Crash with compound collisions of convex hulls

[carli2]

Hi,

The following occurs after digging a while in the gwX-Landscape (which is basically a compound collision of hulls and digging means removing the compounds and hulls and building them again)

Code: Select all

gwX.engine: ../../source/physics/dgCollisionConvex.cpp:1840: virtual dgInt32 dgCollisionConvex::CalculatePlaneIntersection(const dgVector&, const dgVector&, dgVector*) const: Assertion `maxCount < 512' failed.

[Julio Jerez]

you need to move to core 300.

core 300 has unlimited compound subshapes

you need to move to core 300.

core 300 has unlimited compound subshapes

Is core300 API compatible to latest Core200?
Some people already tested to just replace the dll on windows, but it "did not work"

core300 compiled for linux, but I got:

Code: Select all
