OpenGLES rotation in fixed coordinate system
- by Jenicek
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.
