July 14, 2011 Morgan McGuire modified the model from Crytek's OBJ
|
|
export to correct some small errors. He computed bump maps from the
|
|
normal maps using <a
|
|
href="http://cs.williams.edu/~morgan/code/">normal2bump.cpp</a> (since
|
|
MTL files expect height bumps, not normals), put the "mask" textures
|
|
into the alpha channel of the associated diffuse texture, cleaned up
|
|
noise in the masks, created the missing gi_flag.tga texture, and
|
|
removed the long untextured banner floating in the middle of the
|
|
atrium that appears in the file but in none of the published images of
|
|
the model. The banner is in banner.obj.

Sponza Model
|
|
August 19, 2010

|
The Atrium Sponza Palace, Dubrovnik, is an elegant and improved model created by Frank Meinl. The original Sponza model was created by Marko Dabrovic in early 2002. Over the years, the Sponza Atrium scene has become one of the most popular 3D scenes for testing global illumination and radiosity due to it's specific architectural structure which is particularly complex for global illumination light.
|
|
|
|
However, nowadays it is considered as a simple model, thus it was decided to crate a new model with highly improved appearance and scene complexity. It is donated to the public for radiosity and is represented in several different formats (3ds, Obj) for use with various commercial 3D applications and renderers.
