Awesome, it seems there is hardware acceleration for the clothing solver, particles and fluids on most modern NVIDIA GPUs. Would be cool to see some SPH.
Exactly Sir @jvcleave, the PhysX 3.3.3 running on Tegra k1, right now Iām trying to cross compile from linux to Android, I am having some problems with the compiler of ndk9d but is solvable, short news updates.
Yes Sir @amnon , I am also very excited about the new future.
regarding the Smoothed particle hydrodynamics-personally Iāve always had a soft spot for fluid dynamics, I always try alone to write something without good results, now with physx changes everything, I hope to pack a examples of SPH.
I have some examples on the repository of 3D fluid but the cast is processed in CPU.
Do you intend to turn these tests into an ofxAddon eventually? If so, I hope it will include support for windows/codeblocks. And a step-by-step on making it work, I suppose one needs to register and get the SDK (source) or something? Anyway, looking forward to trying this some day. Very promising. Keep up the good work!
@amnon for the moment is a study phase of the sdk,
just have a good familiarity with it I provide to package ofxaddons and test on most operating systems.
are under linux; but do not use codeblocks, in any case I think the editor codeblocks
to its system for linking external libraries (probably very simple).
However, to be clear on how to properly link an external library like the new PhysxNvidia then you can refer to config.make of one of the examples:
as can be seen from the example config.make above the folder there is another folder called āphysxNVā here I quote what you need for a compilation of physx 3.3.3:
includes
lib
lib
bin
careful to use the correct link for the operating system.
Iām on a debian 64 bit then in config.make find links to:
Lib/linux64
lib/linux64
Bin/linux64
etcā¦
Referring to your question, the answer is yes!
but there are some fundamental differences between 3.3.3 and 3.3.2
Now my Physx3.3.2 correspond to physxNV folder but
when i compile the make file it return those errors:

If i undertood, it compile in C and we need C++,
but i have g++ installed !?. may be i need something like g+Ā±mingw-w64 deb ?
