The IMA department of the UdG with his SIR project has developed a realistic ilumination simulation of the new UdG building, called P4. This page offers screenshots, videos and 3D models of this building and results obtained using different illumination algorithms.
3D Model
The building is composed by three floors, with doors and windows. In addition, there is an exterior environment that simulates an horizont. There exists multiple light sources inside each floor and one general exterior light that simulates the sun. This 3D model is in MGF format, and has four different walkthroughs (one per level) in MGFE format.
You can download the 3D model here:
- p4.tar.gz (with absolute paths-suited for SIR applications)
- p4_ext.tar.gz (with relative paths-suited for RenderPark, etc.)
There are also the 3D model in other formats :
The features of these models haven't been tested or couldn't be translated from MGF (materials, light emitters, ...). Please, contact with albertm@ima.udg.es if there is any problem or if other format is required.
New P4 model
version.
P4 2.0 has these new features :
- Geometry structured in an intuitive tree data
- All non-convex polygons have been tesselated
- All building lights are placed and sized like real P4 building
- Brick texture applied to exterior and some interior walls
- Some changed materials, such exterior windows and metals
- Holes have been placed in ceilings/floors of each level. Also a glass
material has been applied to each hole
- A few wrong geometry has been repaired
- The model contains 57000 polygons, aprox.
You can download this model in VRML 2.0 format here :

Screenshots
Some screenshots (obtained with the multi-frame, ray tracer and hierarchical Monte Carlo radiosity algorithms) of different places inside the building are shown below:

Walkthrough videos
Three walkthroughs (one per level) have been also produced by using the multi-frame algorithm.
