Question

My code draws a 3D world, with a 2D set of graphics on top of it. The 3D world is made out of textured quads and the textures are generated with the following code:

textures = []

image = pyglet.image.load(os.path.join(img_dir, "magic.png"))

textures.append(image.get_texture())

glEnable(textures[-1].target)
glBindTexture(textures[-1].target, textures[-1].id)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, image.width, image.height,
    0, GL_RGBA, GL_UNSIGNED_BYTE,
    image.get_image_data().get_data('RGBA',
    image.width * 4))

The quads are then drawn with (the other 2 just have different coords):

glBindTexture(texture.target, texture.id)
glBegin(GL_QUADS)
glTexCoord2f(0.0, 0.0); glVertex3f(4.0, -2.0, 100.0+self.clock)
glTexCoord2f(1.0, 0.0); glVertex3f(4.0, -2.0, -100.0+self.clock)
glTexCoord2f(1.0, 1.0); glVertex3f(-4.0,  -2.0, -100.0+self.clock)
glTexCoord2f(0.0, 1.0); glVertex3f(-4.0,  -2.0, 100.0+self.clock)
glEnd()

I have set up the correct parameters when drawing the 3D and 2D graphics, and when I draw a 2D triangle on top of the 3D quad (with the following code) everything works fine:

glBegin(GL_TRIANGLES)
glVertex3f(0.0, 10, 0.0)
glVertex3f(-10, -10, 0)
glVertex3f(10, -10, 0)
glEnd()

However, I then try to draw a sprite and the 3D quads lose their texture and are drawn as white.

self.spr=pyglet.sprite.Sprite(pyglet.image.load(os.path.join(img_dir, "largebullet.png")).get_texture())
...
self.spr.draw()

Note that there’s some fog in the background

Answer 1

I found a solution to this, by running glDisable(texture.target) on the enabled textures after they were drawn. It’s not ideal because they have to be reenabled again, but for now it works ok.
