WebNov 2, 2012 · 1. Every rotation in gl is according to a given vector. Dependending from where you are looking at the triangle, you will have to rotate according to that vector. For instance, if you are looking from z>0, you have to rotate your triangle with. inZ = 1. such that the triangle rotates according to the vector (0,0,1). WebglRotatef ( angle, x, y, z) Parameters. Variables Description; angle Specifies the angle of rotation, in degrees. x, y, z Specify the x, y, and z coordinates of a vector, respectively. Sample Code References. The following code samples have been found which appear to reference the functions described here. ...

Note that if I change the code so that (0,0) is the center of the window, glRotatef(angle, 0., 0., -1.); will indeed work, rotating the rectangle around its center.

WebHowever, I don't understand the rotation concept at all. If I do glRotatef(1,0,0,1) it makes my quad spin around. If I just do glRotatef(1,0,0,0) it makes the quad smaller (further away) but if I try to rotate around the X or Y axis, I get a black screen. I don't understand the angle either.
