Updating the cinematographic videos: Virtual Office

Real Time Render is a great tool that allow us to live experiences in a much more natural way, giving us the freedom to interact with the environment, to move freely and to pay attention to the things that interest us.

This doesn't mean at any point that other directed and closed methods as the cinema are loosing its value. Cinema allow us to transmit in a very direct way and the viewer only needs to pay attention to what we want to communicate. Right now in Moøkan we are recording video footage of our projects to offer both communication options.

Through this new step we finally integrate one of the features key to choose Unreal Engine 4 as our main tool; the capability to produce video footage from the scenes we have created on it. It has a really high speed rendering that allows us to create a video from one of our projects with a very low cost of computing time.
 

The first one is from our Virtual Office

Villalonso´s Castle

On this article we are going to talk about these two new 3D models created by drone photogrammetry, where we can appreciate the Villalonso´s castle, on one with the surroundings and on the other with more detail. We share a free light version through Sketchfab, ideal to visualize it from the smartphone with a low consumption data, while the complete version is available for sale on Snaptank.

This small but remarkable castle, located in the province of Zamora, Spain, is one of the best preserved in the region. Nowadays we still can appreciate it in a very similar condition to the  original. The present construction dates back to the XV century, although this fortification is already named on earlier texts when it belonged to the Calatrava Order.

The castle is made of limestone masonry, with a prototypic square floor plan, with cylindrical towers on the corners, an Homage Tower with a cornice of machicolations and all of it surrounded by a complete line of battlements. Also its moat can still be noticed, currently almost completely flooded, as well as the remains of a second outside wall with polygonal towers.

 

This fortification has been scenario of historical events as the conflict between Joanna la Beltraneja and the Catholic Monarchs. More recently it has provided the setting for two movies, been the most remarkable “Robin and Marian” performed by Sean Connery and Audrey Hepburn.

Nowadays the castle is a private property, and it can be visited on Sundays and public holidays from 12:00 to 14:00. In our aim to facilitate access to culture and heritage we hope our model can be helpful for those who want to know the fortification.

The day we captured the images for this photogrammetry the environment conditions were really good. The cloudy day allowed us to capture images without shadows from the direct sunlight. It was a windy day and at some point it was a bit difficult to pilot the drone, a DJI Phantom 4, but its stabilization system and attitude system made it possible to take fine photos and recover the course seamlessly and we were pleasantly surprised.

We are really satisfied by the results achieved after our optimization efforts thanks to the simple geometry of the monument and the new software Instant Meshes of retopology that we shortly ago implemented to our workflow. It gave us a great result for detection and maintenance of shafts to maintain the basic geometry while we reduced the polygons.

Castillo de Villalonso


En este artículo presentamos dos nuevos modelos 3D capturados por fotogrametría dron, donde podemos apreciar el castillo de Villalonso en su entorno y en detalle. Aquí compartimos gratuitamente la versión ligera mediante Sketchfab, ideal para ver desde el móvil sin un elevado consumo de datos, y la versión íntegra a la venta en Snaptank.

Este pequeño pero impresionante castillo, en la provincia de Zamora, España, es uno de los mejor conservados en la región. A día de hoy se puede apreciar en un estado muy semejante al original. La construcción actual data del siglo XV, aunque la fortificación es mencionada en textos anteriores cuando perteneció a la orden de Calatrava.

El castillo está construido en sillería de roca caliza, con una planta prototípica cuadrada, cubos cilíndricos en las esquinas y la torre del homenaje con una cornisa de matacanes, todo ello rematado con una línea completa de almenas. Se puede apreciar también su foso, actualmente medio anegado, así como los restos de un segundo muro exterior con torres poligonales.

 

La fortificación ha sido escenario de sucesos históricos como la cuestión entre Juana la Beltraneja y los Reyes Católicos. Más recientemente ha sido escenario de dos películas, donde destaca "Robin y Marian" con  Sean Connery y Audrey Hepburn.

Esta fortificación, hoy propiedad privada, se puede visitar los domingos y festivos de 12:00 a 14:00. En nuestro deseo de facilitar el acceso a la cultura y patrimonio esperamos que nuestro modelo pueda servir de ayuda para aquellos que desean conocer el castillo.

En este caso hemos contado con unas condiciones bastante favorables para la captura del edificio en 3D. El día nublado nos ha permitido tomar fotos sin sombras de la luz directa del sol. Sí es cierto que el viento en algún caso dificultó el manejo del dron, un Phantom 4, pero sus sistemas de estabilización y posicionamiento nos permitieron tomar buenas fotos y recuperar siempre la trayectoria sin esfuerzo lo que nos dejó gratamente sorprendidos.

Nuestros trabajos de optimización en este caso han dado unos resultados realmente satisfactorios gracias a la sencilla geometría del monumento y el nuevo software Instant Meshes de retopología que hemos implementado en nuestro trabajo. Gracias a lo cual hemos obtenido un magnífico resultado en detección y conservación de los ejes para que al reducir los polígonos saliese a la luz la geometría elemental.

在圣比森特德尔瓦列的圣母升天教堂

The Church of the Asunción (before known as Saint Mary's Church) in San Vicente del Valle, Burgos. The nave is one of the best preserved buildings of the pre Romanesque architecture in Spain. This church is dated at the end of the VI century a.c. and is in a dominant position in the high valley of the Tirón River between La Sierra de la Demanda and Los Montes de Ayago.

The church was about to become a ruin after the fire of 1985, when the wooden roof was lost. The fire also uncovered some architectural elements hidden for centuries. These remains caught the interest of experts and local authorities thanks to the efforts of the local priest to preserve the building. Finally, at the beginning of the 90´s the local government and the bishopric funded the restoration putting in value the Visigothic origin of the church.

In Moøkan we want to contribute to the preservation and promotion of this piece of the Spanish heritage by digitalizing the church’s volume through the drone photogrammetry. At the end of the spring of 2016, we went to this stunning spot with our flying equipment. Now after completing the digital reconstruction in our offices we publish and share our work here.

We hope our models will allow everyone to come closer to the church of La Asunción, having a better experience than just through the photos, and if possible, encourage anyone interested to go to San Vicente del Valle to visit it.

The church shows similarities to other pieces of the same period as Santa María de Quintanilla de las Viñas, San Pedro de Arlanza, Santa Cecilia de Barriosuso, San Román de Tobillas, Santa María de los Arcos de Tricio o Santa Coloma.

To further deepen on this monument we recommend the text by Fernando Arce Sainz, from the CSIC: La iglesia altomedieval de la Asunción en San Vicente del Valle (Burgos): historiografía, estratigrafía e interpretación. It has been our main source.

This time we performed the aerial photogrammetry with a DJI Phantom 4 and supported with more photographs of our DSLR camera. In total we have used 110 images that allowed us to create a model with over 20 million of points.

We had a splendid sunny day that allowed us to enjoy an incredibly beautiful view, but the environmental conditions for the collection of data weren’t ideal for a correct digitalization. The best conditions for a photogrammetry is to have a cloudy day.

From this data we created three final models. The first and less detailed represents the area, to appreciate the church in its landscape context on one of valley slopes. The other two are more detailed models of the church to appreciate many more details, one made only with drone photography and the other with a mixed technic.

We have optimized these models lowering its polygon number for the online version, and we are sharing it here with you in Sketchfab from where you can download it for free. On this models the discarded detail is provided by the texture on the normal layer.

We show both models since they have different level of detail. The mixed technic model has a more detailed geometry showing cornice elements that weren’t captured by the photos of the drone. Due and incident with our equipment, the lens of our DSLR was damaged so the texture presents some defects and blurry areas. The model done only with the photos of the drone has a higher definition of the textures.

As result of the photogrammetry we can also explore the geometry without the texture to appreciate some details that otherwise would be hidden or hard to see.

We can see an example on the roof. When we explore the model we can perceive some lines that appear on the roof separated an equal distance. The first idea was that it could be cause by a deformation of the roof and showing the position of the beams. The images of the cornice and the interior showed us that wasn’t a valid theory since we could see a higher number of beams.

Finally, after studying carefully the photos we discovered these lines were more obvious from some angles. They are rows of tiles reinforced with cement mortar to ensure the durability of the roof. That makes that row to stand out slightly above the rest.

To see the 3D model in other graphic modes, select the button options on the Sketchfab visor, render, and choose between the different modes.

The photogrammetric study is also a scientific tool to study objects, buildings and terrains, allowing us to see much more than the obvious and analyze an element or site without going to visit it. A tool of great value to analyze projects of intervention in the architectural heritage or other existent structures as well as for topographic analysis.

La Iglesia de La Asunción en San Vicente del Valle

La iglesia de La Asunción (antes conocida como de Santa María) en San Vicente del Valle, Burgos. La nave es una de las construcciones mejor conservadas de la arquitectura prerrománica en España. De origen visigodo datado a finales del siglo VI d.C. La iglesia está en un posición dominante en el alto valle del río Tirón entre La Sierra de la Demanda y Los Montes de Ayago.

La iglesia estuvo apunto de convertirse en una ruina tras un incendio en 1985, en el que la cubierta de madera se perdió. El incendio también dejó a la vista algunos elementos de la arquitectura que llevaban siglos ocultos. Los restos aparecidos lograron captar el interés de los expertos y autoridades locales gracias al esfuerzo del párroco local en preservar el edificio. Finalmente a principio de los 90 el gobierno local y el obispado financiaron la restauración donde se puso en valor el origen Visigodo de la iglesia.

En Moøkan hemos querido contribuir a la conservación y difusión de esta pieza del patrimonio español con la digitalización de la volumetría de la iglesia mediante fotogrametría drone. Para ello nos hemos desplazado hasta este abrumador enclave a finales de la primavera de 2016 con nuestro equipo de vuelo. Ahora tras haber completado la reconstrucción digital en nuestras oficinas publicamos y compartimos nuestros trabajo aquí.

Esperamos que nuestro modelos permitan a todos acercarse virtualmente a La Asunción, teniendo una experiencia más completa que la de la fotografía, y si cabe animar a interesados a visitarla en San Vicente del Valle.

La iglesia muestra semejanza a otras obras coetáneas como Quintanilla de las Viñas, San Pedro de Arlanza, Santa Cecilia de Barriosuso, San Román de Tobillas, Santa María de los Arcos de Tricio o Santa Coloma.

Podemos observar sus fábricas altomedievales donde en la parte inferior, de la fundación podemos ver una obra de sillería con materiales reciclados de otras edificaciones romanas. En sucesivas intervenciones también prerrománicas se recreció la altura de la nave añadiendo 5 ventanas geminadas donde destacan los capiteles de bella talla que han sido fundamentales en el proceso historiográfico de datación.

La iglesia cuenta con cuatro etapas de construcción altomedievales, en las que se configura la mayor parte del volumen que podemos ver hoy. Las modificaciones continuaron en toda su historia. A las reformas renacentistas se debió que se ocultase el origen visigodo de la iglesia cuando se cegaron y macizaron las ventanas altas geminadas y se cubrió el aula con falsas bóvedas de arista.

Del periodo moderno, es claramente visible hoy día el recrecido en la espadaña. Arrancando desde la espadaña antigua se construye la nueva con dos cuerpos, el primero con dos arcos de medio punto. El segundo cuerpo tiene un arco central de medio punto flanqueado con aletas semicirculares y rematado en un frontón curvo. Sobre estos unos pináculos de tipo herrerianos con las típicas bolas.

Para seguir profundizando sobre este monumento te recomendamos el texto de Fernando Arce Sainz, del CSIC: La iglesia altomedieval de la Asunción en San Vicente del Valle (burgos): historiografía, estratigrafía e interpretación. Que ha sido nuestra principal fuente.

En esta ocasión hemos realizado la fotogrametría aérea con un drone Phantom 4 de DJI y apoyado con fotos de corto alcance con nuestra DSLR. En total hemos usado 110 fotografías de las cuales hemos obtenido un modelo de casi 20 millones de puntos.

Las condiciones para la toma de fotos no eran las ideales, si bien el día soleado brindaba una vista inigualable, lo ideal para una correcta digitalización es un día nublado.

Sobre este hemos generado tres modelos finales. El primero con menor detalle para representar el área, donde se puede apreciar en su contexto paisajístico en una de las laderas del valle. los siguientes son modelos más detallado de la iglesia donde se pueden apreciar muchos más detalles uno con solo fotografía drone y el otro con técnica mixta.

Finalmente estos modelos los hemos optimizado reduciendo sus polígonos para su versión online, la que aquí estamos compartiendo mediante Sketchfab y que se puede descargar libremente. Modelos donde el detalle descartado se aporta mediante las textura en la capa normal.

Mostramos los dos modelos pues aunque el de técnica mixta tiene más detalle en la geometría mostrando elementos de la cornisa que desde el drone no se fotografiaron. Debido a un incidente con nuestro equipo la óptica de nuestra DSLR quedó dañada por lo que la textura presenta algunos defectos y áreas desenfocadas. Así la textura del modelo drone presenta mejor definición.  

Como resultado de la fotogrametría también podemos explorar la geometría de sin textura para poder apreciar detalles que de otra manera quedan ocultos a simple vista o resultan más difíciles de percibir.

Este es el caso de lo que encontramos en la cubierta. cuando exploramos el modelo obtenido nos fijamos en unas líneas que aparecen sobre la cubierta de forma cada cierta distancia. La primera idea fue que se tratase de alguna deformación que nos estuviese mostrando la posición de la vigas. Las imágenes de la cornisa y del interior nos llevaron a descartar esa opción pues se ve claramente que hay muchas más vigas.

Finalmente tras estudiar cuidadosamente las fotos descubrimos esas líneas desde algunos ángulos si eran más evidentes. Se trata de unas hileras de tejas reforzadas con mortero para mejorar la durabilidad de la cubierta. Lo que hace que esa fila de tejas sobresalga levemente sobre el resto.

Para ver el modelo 3D en otros modos gráficos, selecciona en el visor de Sketchfab el botón de opciones, render, y elige los distintos modos.

Concluyendo, el estudio fotogramétrico resulta también una herramienta científica para estudiar objetos, edificios y terrenos, permitiéndonos ver mucho más de lo evidente y analizar una obra sin tener que visitarla físicamente. Una herramienta de gran valor a la hora de analizar un proyecto de intervención en patrimonio u otras estructuras existentes o para análisis topográficos.

Dragons from Tian Hou Temple

After a visit to the Tian Hou Temple, Shekou, Shenzhen, we have create two new examples of photogrammetry models. The temple is a reconstruction of one of the most ancient buildings of what today is Shenzhen, a temple dedicated to TianHou the Mother Of Heaven and goddess of the Sea. The legend says it was built to show gratitude to the goddess for saving the great flee of the famous admiral ZhengHe around the year 1410. From that date the temple has been rebuilt many times, the last one in the 90's of last century. 

We have recreated two elements, that now we share with you through Sketchfab. The first, is one of the two symmetrical sculptures of dragons from the first platform of the inside courtyard. The second one is a decorative element from a traditional stone handrail with a relief of a dragon on the clouds flying over the sea. 

This two models have been optimized to be easy to show on a browser. The dragon sculpture, originally have 6.5 million polygons, a model of 450 Mb. Now you can download it just with 30k polygons with only 1,9 Mb including two texture maps, for diffuse color (the material you can see) and a normal map (to recuperate the detail loss by the polygon reduction).

Dragones del templo Tian Hou

Tras nuestra visita al templo Tian Hou, en Shekou, Shenzhen, hemos creado dos nuevos ejemplos de modelos fotogramétricos. El templo es una reconstrucción de una de las edificaciones más antiguas de lo que hoy es Shenzhen, dedicado a TianHou la madre del cielo y diosa del mar. La leyenda dice que fue construido para agradecer a la diosa el que salvase la gran flota del famoso almirante ZhengHe alrededor del año 1410. Desde entonces el templo ha sido reconstruido en muchas ocasiones, la última en los años 90 del pasado siglo. 

Hemos recreado dos piezas, que ahora queremos compartir con vosotros a través de Sketchfab. El primero es uno de las dos esculturas de dragón simétricas de la primera plataforma del patio interior. El segundo es un fragmento decorativo de una barandilla tradicional de granito, con un relieve de un dragón entre las nubes, que vuela sobre el mar. 

Estos dos modelos han sido optimizados para poder verse fácilmente desde el navegador. La escultura del dragón, originalmente tenía 6.5 millones de polígonos, un modelo de 450 Mb. Ahora puedes descargarla con tan sólo 30 mil polígonos en 1.9Mb incluyendo dos mapas de texturas, uno para el color difuso, el material que puedes ver; y otro el mapa normal, que recupera el detalle perdido en la reducción de polígonos.
