Hello all, I'm confused about TextureGrid. I'm creating one from an
ImageGrid, and what I expect is that my image will be chopped into texture
tiles, so that each element in the TextureGrid is a quadrant of my image.
The image I'm using is 512x512. What I thought I would see was the
bottom-left 256x256 corner of the window matching the bottom-left 256x256 of
the image, while the rest of the window would be the black default clear
color.
I'm on python 2.6, vista, pyglet 1.1.3.
Here's a minimal version of the code:
import pyglet from pyglet.gl import * class
MainWindow(pyglet.window.Window): def __init__(self, *args, **kwargs):
pyglet.window.Window.__init__(self, *args, **kwargs) img =
pyglet.image.load("small_background.png") self.grid =
pyglet.image.ImageGrid(img, 2, 2) self.txgrid =
self.grid.get_texture_sequence() def on_draw(self):
glClear(GL_COLOR_BUFFER_BIT) verts = [0.0, 0.0, 256.0, 256.0] tex =
self.txgrid[0, 0] glEnable(tex.target) glBindTexture(tex.target, tex.id)
glBegin(GL_QUADS) glTexCoord2f(0.0, 0.0) glVertex3f(verts[0], verts[1], 0.5)
glTexCoord2f(1.0, 0.0) glVertex3f(verts[2], verts[1], 0.5) glTexCoord2f(1.0,
1.0) glVertex3f(verts[2], verts[3], 0.5) glTexCoord2f(0.0, 1.0)
glVertex3f(verts[0], verts[3], 0.5) glEnd() if __name__ == '__main__': w =
MainWindow(512, 512) pyglet.app.run()
Thanks,
