Another NVIDIA developer session from GDC 2011 is now available – Realistic and Interactive Clothing in Epic Games “Samaritan” Demo Using NVIDIA APEX (in .pdf format).
Update: recorded session is now available at GDC Vault. Content of this post was updated accordingly.
New interesting technic was presented during presentation – highly detalized graphical mesh with many details (pockets, clasps, etc) was attached to a simplified uniformly tesselated mesh called “Drive Mesh“, that was used for APEX Clothing simulation. In this case, clothing with very complex geometry (like on the Samaritan character above) can be easily authored and simulated with high performance.
Also, APEX Particles authoring process has been upgraded with additional feature – this module now can be connected to game engine editor via .dll (if developers prefer their own particle editor), or still can be authored via PhysXLab, as before.
Some interesting facts: APEX Clothing is using SPUs on PS3 console; there is a plan to bring APEX to mobile platforms (like Tegra).
