罗丹(Rodin)作品:亚当(Adam)

我们的第二件雕塑模型是罗丹的作品:亚当。这个雕塑模型高56厘米,比原始雕塑作品尺寸要小,作为1881年罗丹雕塑作品群“地狱之门”中亚当家族的模型测试版本。似乎在创作这个雕塑群之前,罗丹已将它视为类似于米开朗基罗的作品“人的创造”。

这个测试版模型与最终雕塑作品仍然有一些明显的差异,特别是头部和左手,但是它的构图和概念已经非常之清晰。雕塑的右手则与米开朗基罗的作品“人的创造”类似。

这个新的模型我们使用了126张照片,生成的模型包含了430万个多边形面。我们将它优化为3.9万个面使其可用于在线版本。这个模型可于Sketchfab上免费下载,更高分辨率的专业版本则可在Snaptank找到。

Adam by Rodin

Our second piece for this sculpture collection is a miniature of Rodin's Adam. This piece of smaller scale than the original, 56cm, seems to be a pre-test to the sculpture of Adam finally made in 1881 to place on the sides of "The Gates of Hell". Although it seems that before this assignment, Rodin already had exposed like "the creation of the man".

There are obvious differences between the final sculpture and this test, especially in the head or left hand, but the composition and concepts were already clear. The right hand a clear link to Michelangelo's "The Creation of Adam" remains the same.

For this new model we have used 126 photographs, with which we have generated a model of 4.3 million polygons. Model that we have optimized for its online version to 39 thousand polygons. The model is ready for free download from Sketchfab, and the high resolution version for professional use at Snaptank.

Juan Bordes, Sculpture

Today in our blog we start a new series of articles with sculptures that we have scanned in 3D. With this initiative we want to continue sharing from Moøkan our work, especially in the field of cultural diffusion and promotion. Thanks to the agreement with some of our clients we will share some of the sculptures of their private collections giving public access to them in a digital environment.

We have chosen to start, the most contemporary of this series. A complete body of sculptor and architect Juan Bordes, A 46 cm piece in bronze lacquered in white.

The sculptor, member of the Royal Academy of Fine Arts of San Fernando and author among other publications "History of the human figure: drawing, anatomy, proportion, physiognomy". He is one of the greatest theoreticians on the human figure and its representation. Which is why we chose this sculpture to start this series.

The model was made by photogrammetry. Using 117 photos and generating a detailed model of 10 million polygons and an 8k texture. The version presented here, designed for web, has been simplified to 36 thousand polygons after been retopologized, and two textures, the color (diffuse) and the normal map, that collects the information lost in the polygons reduction.

Pictures from the original model.

Juan Bordes, escultura

Hoy en nuestro blog empezamos una nueva serie de artículos con esculturas que hemos escaneado en 3D. Con esta iniciativa desde Moøkan queremos seguir compartiendo nuestro trabajo, especialmente en el ámbito de la divulgación cultural. Gracias al acuerdo con algunos de nuestros clientes vamos a compartir algunas de las esculturas de sus colecciones privadas dando acceso público a ellas en un entorno digital.

Hemos elegido para empezar, la más contemporánea de esta serie. Un cuerpo completo del escultor y arquitecto Juan Bordes, Una pieza de 46 cm en bronce y lacada en blanco.

El escultor, miembro de  la Real Academia de las Bellas Artes de San Fernando y autor entre otras publicaciones “Historia de la figura humana: el dibujo, la anatomía,la proporción, la fisiognomía” es en uno de los mayores teóricos sobre la figura humana y su representación. motivo por el que hemos elegido esta escultura para empezar esta serie.

El modelo lo hemos realizado por fotogrametría. Empleando 117 fotos y generando un modelo detallado de 10 millones de polígonos y una textura de 8k. La aquí expuesta, su versión web, ha sido simplificada a 36 mil polígonos tras una retopologia; y dos texturas: la de color y el mapa normal, que recoge la información perdida en la reducción de polígonos.

Pictures from the original model.

Fotoescultura y fotogrametría un salto de 150 años.

La fotogrametría es una técnica moderna de la captura digital de modelos reales, de la que ya hemos hablado anteriormente en este blog. técnica con la que trabajamos en la reconstrucción de esculturas o edificios. Esta técnica analiza un grupo de fotos de un modelo de diversos puntos de vista y con ellas y bastantes operaciones de triangulación obtenemos un modelo automático en 3D.

El modelo resultante gracias a la impresión 3D no queda limitado al mundo digital sino que puede materializarse como una escultura en un proceso también automatico. Esto que hoy día es posible gracias a la tecnología actual, pero fue imaginado de forma similar por Fraçoise Willème en 1860. Lo llamo fotoescultura, una técnica que necesitaba aun de mucha mano humana pero que realmente soñaba industrializar la escultura.

La fotoescultura llegó a tener cierta fama en su época y retrató a la corte imperial francesa, o a la corte española de Isabel II por su socio en España Jean Laurent. Lamentablemente esta técnica tenía un elevado coste y encontraría el rechazo de la mayoría de los artistas de su época quienes se posicionaron en contra los avances tecnológicos que empezaban a dominar el mundo.

La técnica es un claro antecedente de lo que hacemos hoy día con la fotogrametría. Consistía en tomar 24 fotografías simultáneas de la persona a retratar, en un sala dispuesta para ello. Con estas fotografías y la ayuda de un pantógrafo se dibujaban las siluetas del modelo a la escala deseada. Estas siluetas eran como gajos con los que se construía un modelo que finalmente un artista trabajaría para dar el detalle suficiente a la escultura.

Lo más interesante es que el material del que partían, fotografías desde distintos puntos de vista es lo mismo que utilizamos en la fotogrametría por lo que el material fotográfico que Willème y sus socios crearon podría servir para crear modelos fotorrealistas de la alta sociedad del siglo XIX, creando un vínculo que salta 150 años en el tiempo y tecnología, uniendo la era del vapor con la digital.  

En Moøkan nos hemos decidido a intentar lograr este vínculo y homenajear la obra del escultor francés buscando archivos originales de sus estudio para poder procesar sus fotografías y reconstruirlas en 3D. Esperamos poder actualizar pronto este proyecto con nueva información y si es posible algún modelo virtual.

照片雕塑和摄影测量:150年的飞跃

Photogrammetry is a modern technique of digital capture of real models, which we have already talked about in this blog. Technique we work on rebuilding sculptures or buildings. This technique analyzes a group of photos of a model from different points of view and with them and many triangulation operations we obtain an automatic model in 3D.

The resulting model thanks to 3D printing is not limited to the digital world but can materialize as a sculpture in an automatic process. This is now possible thanks to the current technology, but it was similarly imagined by Fraçoise Willème in 1860. He called it photo-sculpture, a technique that still needed a lot of human handcraft but really dreamed of industrializing sculpture process.

The photo-sculpture came to have a certain fame at the time and portrayed the French imperial court, or the Spanish court of Isabel II by his partner in Spain Jean Laurent. Unfortunately this technique had a high cost and would find the rejection of the majority of the artists of its time who stood against the technological advances that began to dominate their world.

This technique is a clear antecedent of what we do today with photogrammetry. It consisted of taking 24 simultaneous photographs of the person to be portrayed in a room prepared for it. With these photographs and the aid of a pantograph the silhouettes of the model were drawn to the desired scale. These silhouettes were like segments with which a model was built that finally an artist would work to give sufficient detail to the sculpture.

The most interesting thing is that the material with which they worked, photographs from different points of view is the same as we used in photogrammetry, so the photographic material that Willème and his partners created could serve to create photorealistic models of the high society of the nineteenth century, Creating a link that leaps 150 years in time and technology, linking the era of steam with digital.

In Moøkan we have decided to try to achieve this leap and to honor the work of the French sculptor by searching original files of his studio to be able to process his photographs and reconstruct them in 3D. We hope to be able to update this project soon with new information and if possible some virtual model.

Vulkan: gráficos móviles de alta calidad

Día a día la capacidad de los teléfonos inteligentes se aproxima más a la de los ordenadores de sobremesa acercándose poco a poco a la llamada convergencia. Cuando ambas plataformas ofrecerán funcionalidades y calidades similares.

Esto supone muchas ventajas tanto para los usuarios que encontrarán mayores y mejores compatibilidades como para los desarrolladores que podremos producir más fácilmente en entornos multiplataforma.

Vulkan es un nueva API grafica (una herramienta de sistema que las aplicaciones con graficos 3D usan) que poco a poco reemplazará al OpenGL en en todo tipo de dispositivos para generar gráficos 3D de última generación. Pero lo que nos interesa en caso es es que Vulkan funciona tanto en windows como en Android, acercándonos a la convergencia.  

Sin duda el mayor avance supone para las aplicaciones en el mundo móvil, que hasta ahora estaban limitadas por OpenGL. Esta nueva tecnología permitirá un gran aumento en el realismo del 3D en tiempo real para Android. Por ahora apenas es compatible con el Samsung Galaxy 7, Google Pixel o el nuevo Xiaomi Mix, pero pronto lo veremos en muchos más teléfonos.

Como una muestra de esta tecnología Epic Games, desarrolladores del motor gráfico que usamos en Moøkan para generar nuestras aplicaciones, ha creado una aplicacion para la presentación del Samsung Galaxy 7, Protostar una demo en tiempo real que funciona en estos telefonos mostrandonos todo el potencial de Vulkan y Unreal Engine 4.

 

 

Vulkan realmente supone un gran salto para los dispositivos móviles que junto a Google Daydream nos confirman nuestras expectativas para el mercado de las Experiencias Virtuales y la Realidad Virtual, como algo accesible para todos en los próximos 2 años.

Vulkan:高品质的移动图形

Day by day the capacity of smartphones is closer to that of desktop computers gradually approaching the so-called convergence. When both platforms will offer similar functionalities and qualities.

This will brings many advantages for users who will find greater and better compatibilities as well as for developers who can more easily produce in cross-platform environments.

Vulkan is a new graphics API  (a system tool that 3D graphics applications use) that will gradually replace OpenGL on all kinds of devices to generate next-generation 3D graphics. But what interests us in the case is that Vulkan works on both windows and Android, approaching convergence.

No doubt the biggest advance is for the applications in the mobile world, which until now were limited by OpenGL. This new technology will allow a big increase in the realism of real-time 3D for Android. For now it only supports the Samsung Galaxy 7, Google Pixel or the most recent Xiaomi Mix, but soon we will see it on many more phones.

As a sample of this technology Epic Games, developers of the graphics engine that we use in MooKan to generate our applications, has created an application for the presentation of Samsung Galaxy 7, Protostar a real-time demo that showing the full potential of Vulkan and Unreal Engine 4.

 

 

Vulkan really is a big leap for the mobile devices that together with Google Daydream confirm our expectations for the Virtual Experiences and Virtual Reality market as something accessible to everyone in the next 2 years.
