opencl

http://enja.org/2010/12/16/particles-in-bge-fluids-in-real-time-with-opencl/ that is great

are there any way NOW to speed up physic in blender ? some plugin/modification ?

It says he modded the GE (which you can do thanks to the GPL, or some license on Blender anyway) I don’t think the guy’d hand out the work because it’d obviously be quite difficult to make… (If he did, look on the site/contact 'em for the build) also check Graphicall.org to see if there is an existing build of Blender with it there, or learn openCL and modify the source code yourself (not a decision to be taken lightly) :smiley:

Taken that Physics in blender means Bullet

Bullet3 -> openCl accellerated
GSoC -> better integration of bullet in blender

Solution 1) : wait until this 2 are completed
Solution 2) : start coding a physic engine compatible with blender in openCl, than create an interface/communication system/way to allow blender and your new library to work together, keeping all the compatibility with the old stuff.

I hardly think solution 1 is the nearest one of the two.
(for the fluid thing, should be the patch somewhere)

Some progress of the BGE and opencl
