I'm trying to draw some objects in Pyglet using the same Vertex List and
transforming; unfortunately, I can't get the shape to appear on my screen.
Why can't I see it? Is this a good way to draw the same shape in different
places with different colors?
from pyglet.gl import *
from pyglet.graphics import *
class PointySide:
neither = 0
left = 1
right = 2
both = 3
v_lists = {}
def getVList(psTup):
if psTup in v_lists:
return v_lists[psTup];
vs = (0,0,3,0)
for i,v in enumerate(psTup):
if v & PointySide.right:
vs = vs + (4,i*4+2)
vs = vs + (3,i*4+4)
for i,v in enumerate(psTup[::-1]): # in reverse now
vs = vs + (0,i*4)
print v
if v & PointySide.left:
vs = vs + (1,i*4+2)
v_lists[psTup] = vs
return vs
# Direct OpenGL commands to this window.
window = pyglet.window.Window()
t = (PointySide.both,PointySide.left)
l = getVList(t)
pointsnum = len(l)/2
vertex_list = pyglet.graphics.vertex_list(pointsnum,
('v2i/static',l),
('c3b/static',(255,0,0) * pointsnum) # * repeats a tuple, because python
)
@window.event
def on_draw():
glClear(GL_COLOR_BUFFER_BIT)
glLoadIdentity()
glPushMatrix()
glTranslatef(-10,-60,0)
#glScalef(2,2,1)
# # #
pyglet.graphics.draw_indexed(4, pyglet.gl.GL_TRIANGLES,
[0, 1, 2, 0, 2, 3],
('v2i', (100, 100,
150, 100,
150, 150,
100, 150))
)
vertex_list.draw(GL_POLYGON);
glPopMatrix()
pyglet.app.run()
