hi ppl
i made a simple class for a square
it has the functions to create a vertex array and to draw it (worked quite well)
now i implemented my own rotations, meaning that i store a matrix containing the transformations and apply it using glmultmatrix before drawing the vertex array using gldrawrangeelements
the problem is that i get render artefacts!!!
now to the strange things
it works well for rotations about the world x-axis (all rotations are done about world axis) but not for y- or z-axis
using immediate mode looks ok and no artefacts appear (for all axis)
i even moved the camera further away as i thought it could be problems with the near clipping plane but that did not help
any ideas?
btw i use a geforce2mx and latest nvidia drivers on linux
any help is highly welcome
thx in advance
