To understand the child, one must study the parent. So to understand 3DRad, one must look at its parent,namely, 3Impact. Having recently become freeware, I decided to take some time off 3DRad and investigate the capabilities of 3Impact5.
I have found that the easiest way for me to study a new engine is to take a project that I know works in another engine, and port it over to the engine that I'm testing. I have had a fair amount of experience with the Nvidia PhysX SDK, integrating its physics into a previous 3D engine. I find that 3Impact/3Drad is sadly lacking on the physics side (it uses the rather outdated ODE physics), so my goal over the next couple of months is to attempt integration of PhysX into 3Impact. You can follow may progress at the 3Impact Forum. There will be downloadable demos illustrating the various tests I am apply
