Why I cannot rotate my cube in PyOpenGL?
I am trying to rotate my cube when I pushed the key 'r' (keyevent), I am using Pyopengl, but I don't know why this doesn't it.
This is a part of my code.
def init():
glMatrixMode (GL_PROJECTION)
glClearColor(0.529, 0.529, 0.529, 0.0)#Definimos color de ventana
glColor3f(0.0, 1.0, 1.0)#Definimos color inicial para el cubo
def dibujarCubo():
glClear (GL_COLOR_BUFFER_BIT)
glColor3f (1.0, 1.0, 1.0)
glLoadIdentity ()
gluLookAt (0.0, 0.0, 5.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);
glutWireCube (1.0)
glFlush ()
def reshape (w, h): #Esta funcion se escarga de reescalar la ventana
glViewport (0, 0, w, h)
glLoadIdentity ()
glFrustum (-1.0, 1.0, -1.0, 1.0, 1.5, 20.0)
glMatrixMode (GL_MODELVIEW)
def keyPressed(*args):
key = args[0]
if key == "r" or key =="R":
glRotatef(30, 1, 0, 0)#Rotate in x
Generally you only want to call OpenGL functions from the display callback.
Modify keyPressed to increment a variable & call glutPostRedisplay() and dibujarCubo to use that variable as a glRotatef() parameter.
尝试在glRotatef（）指令下面再次调用dibujarCubo（）
