Hi,

I'm having real trouble finding out how to rotate an object arround two axes without changing axes orientation. I need only local rotation, first arround X axis and then arround Y axis(only example, it doesn't matter how many transformations arround which axes) without transforming the whole coordinate system, only the object. The problem is that if I'm using glRotatef arround X axis, the axes are rotated also and that's what I don't want. I've red bunch of articles about it but it seems I'm still missing something. Thanks for every help.

To have some sample code here, it's something like this

glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glRotatef(rotX, 1.0f, 0.0f, 0.0f);
glRotatef(rotY, 0.0f, 1.0f, 0.0f);
drawObject();

but this transforms the coordinate system also.
