Session Name:

Eliminating Texture Waste: Borderless Realtime Ptex


In this session, John McDonald will demonstrate a new, border-free technique for rendering Ptex datasets in real-time, on any OpenGL 4 (or Direct3D 11) capable consumer hardware. By jettisoning borders, the memory overhead of this method has even dropped below those of standard texture mapping. Session attendees will see a live Ptex demo running on commonly available consumer hardware. They will dive with John, deep into the guts of a complete, working OpenGL implementation.
