Thank you Joachim, Yes, I saw the depthpeeling example, but as I my graphic card is not enough powerfull I cannot launch it ... Sorting the triangles by depth before rendering is a solution, but as my point of view is constantly changing, is it possible to do such a sort in real time ? May be should I use vertex shader for this ?
