I’m confused with using the glRotatef function of OpenGL.
When I’m calling for this: gl.glRotatef(90f, 1.0f, 0.0f, 0.0f); it rotates in Y direction of the object, like it’s inverted?
Any explanation for this?
glRotatefrequires you to specify the normal to the plane you want it to rotate in. You’ve specified a normal ofx=1, y=0, z=0, which specifies that you want the rotation to occur in theyzplane.
