What I'm doing is basically this, so here's the code:
------------------------------------------------------------
# -*- coding: cp1252 -*-
import pyglet
import math
from pyglet.gl import *
# Direct OpenGL commands to this window.
window = pyglet.window.Window(resizable=True)
@window.event
def on_draw():
glClear(GL_COLOR_BUFFER_BIT)
glLoadIdentity()
#glTranslatef(50.0,0.0,0.0)#Sirve para mover la vista de la
ventana(o algo asi).
rtri = 15
glRotatef(rtri,0.0,0.0,1.0)#Rotating around Z.
#glRotatef(rtri,0.0,1.0,0.0)#Rotating around Y.
#glRotatef(rtri,1.0,0.0,0.0)#Rotting around X.
#COMENZANDO A DIBUJAR EL TRIANGULO.
glBegin(GL_TRIANGLES)
glColor3f(1.0,0.0,0.0)#Color, justo antes del primer vertice (en
RGB---ROJO).
glVertex3f(window.width/2,window.height,0.0)#SUPERIOR.
glColor3f(0.0,1.0,0.0)#Color, justo antes del segundo vertice (en
RGB---VERDE).
glVertex3f(100.0,0.0,0.0)#INFERIOR IZQUIERDO.
glColor3f(0.0,0.0,1.0)#Color, justo antes del tercer vertice (en
RGB---AZUL).
glVertex3f(window.width,0.0,0.0)#INFERIOR DERECHO.
glEnd()
pyglet.app.run()
------------------------------------------------------------
The triangle basically disappears if I don't use decimals in 'rtri'.
If I use the decimals, it is when the triangle starts getting
'slashed.'
