That is what it is doing. Do you have any idea why this works: ... self.tileAtlas = pyglet.image.atlas.TextureAtlas(1025,1025) #non po2 ... add some 16x16 images glEnable(self.tileAtlas.texture.target) glBindTexture(self.tileAtlas.texture.target, self.tileAtlas.texture.id) glBegin(GL_QUADS) glTexCoord2i(0,0) glVertex3i(0,0,0) glTexCoord2i(1025,0) glVertex3i(1025,0,0) glTexCoord2i(1025,1025) glVertex3i(1025,1025,0) glTexCoord2i(0,1025) glVertex3i(0,1025,0) glEnd() and displays the whole texture on the screen. But this does not work: ... self.tileAtlas = pyglet.image.atlas.TextureAtlas(1024,1024) #po2 ... add some 16x16 images glEnable(self.tileAtlas.texture.target) glBindTexture(self.tileAtlas.texture.target, self.tileAtlas.texture.id) glBegin(GL_QUADS) glTexCoord2f(0.0, 0.0) glVertex3f(0,0.0, 0.0) glTexCoord2f(1.0, 0.0) glVertex3f(1.0, 0.0, 0.0) glTexCoord2f(1.0 ,1.0) glVertex3f(1.0, 1.0, 0.0) glTexCoord2f(0.0, 1.0) glVertex3f(0.0, 1.0, 0.0) glEnd() If I add: glMatrixMode(GL_PROJECTION); glPushMatrix(); glLoadIdentity(); before the glBegin, it does display the texture, but almost freezes my video and it gets about .01 fps. -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
