Irrlicht Engine

It's correct. Tolerance can be 0, also rounding errors of tolerance does not influence result.

Spintz :
It depends on model (from average quantity of weights on one vertex). And uselessness of the first nulling cycle on all vertices in not a debugging mode is obvious.

P.S. I'm use VC++6.0 (SP5 ...

To fix threefold count of verices remove
irrMath.h:
inline bool equals(const f32 a, const f32 b, const f32 tolerance = ROUNDING_ERROR_32)
{
return (a + tolerance > b) && (a - tolerance < b);
}
by
inline bool equals(const f32 a, const f32 b, const f32 tolerance = ROUNDING_ERROR_32)
{
return ...

operator*(scalar) и operator+(matrix4) is typical matrix operations.


Threefold count of verices
it's error in CXAnimationPlayer::addFacesToBuffer always return -1

Some optimizations increase FPS to (max, in Debug) 70 (+30).
CXAnimationPlayer.cpp:

void CXAnimationPlayer::modifySkin()
{
// set animated vertices to zero
#ifdef _XREADER_DEBUG
for (s32 k=0; k<(s32)Joints.size(); ++k)
{
for (s32 w=0; w<(s32)Joints[k].Weights.size(); ++w)

Hello! I am using Irrlicht SVN (last).
Without .x model (tyny.x and it's optimized to 2K poly's version) FPS~=160. With model, FPS ~=40.
I'm fix some leaks in modifySkin() and animateSkeleton(), but FPS stil be very slow (~50). Two matrix transform in modifySkin() executed many (~7000) times at one ...
