i can list you atleast 35 titles off had that have used it ... doesn't make it good, just means its popular,
partly because 3D Studio Max's Reactor used it,
partly because Futuremark used it,
partly because Middleware bought out Mathengine earlier this year making them the ONLY professional option now.
Quote: "There are various other engines such as Tokamak or ODE (physics engines) which work with c++, vb and delphi.... The 3d engine I know of which can be used with these 3 languages is truevision3d..."
actually they're both designed purely for C, truevision hacks them for C++,VB,Delphi setups using Object Components - it makes them slow and buggy.
The difference in speed is quite apparent from tests that were displayed on Havok's site for a while when they were doing speed comparisons.
they ran the same demo of 300 cubes in a square collising with another cube you pulled around ... done on a Pentium2 400mhz
there were TTL (time to live/latency) and fps rates given for each demo where the cube was yanked through by a code as a demo and covered for 10seconds.
truevision3d using Tomak under VC++ had a TTL of 620ms and 10fps
Havok using C++ under VC++ had a TTL of 340ms and 35fps
Karma using C under VC++ had a TLL of 180ms and 60fps
although OpenDE is really the cutdown younger brother of Karma, it isn't complex enough for anything too decent enginewise and it speed is hardly amazing.
sorry to burst your bubble about truevision3d mate, but its a VERY VERY slow engine ... and when something makes Quake2 look like a speedy engine sorry that just makes it far too slow compared to what IS out there already.
