A technical demonstration showing an interactive virtual model of an hotel lobby, is available for download. RTGU is a realtime 3d rendering pipeline - composed of a set of tools, ranging from 3d content export/conversion to realtime 3d rendering using OpenGL. The model is completely designed using 3dsMax and V-Ray, then exported and lit using RTGU tools, and rendered using OpenGL 3.x features : rendering uses FBO to do HDR rendering in RGBA16F textures ; tone mapping relies on ARB_texture_multisample extension to resolve MSAA ; linear rendering is achieived by using sRGB textures and framebuffers ; lighting is stored in HDR textures (2D/3D) as lightmaps and spherical harmonics.
