我需要在python Pyglet中制作多维数据集的多维数据集视口,但我总是只有一个。

查看def on_resize():

WINDOW = 1000 
INCREMENT = 5
transparant = False

class Window(pyglet.window.Window):
    xRotation = yRotation = zRotation = 30
    zoom = 1
    far = 100
    dist = 35
    x = y = z = 0

    def __init__(self, width, height, title = '') :
        super(Window, self).__init__( 1300,1000, title)
        pgl.glClearColor(0, 0, 0, 1)
        pgl.glEnable(pgl.GL_DEPTH_TEST)



    def on_draw(self) :

        self.clear()

立方体图

        pgl.glPopMatrix()

    def on_resize(self, width, height) :
        pgl.glClear(pgl.GL_COLOR_BUFFER_BIT | pgl.GL_DEPTH_BUFFER_BIT)

        pgl.glViewport(0, 0, 650, 500)
        pgl.glLoadIdentity()
        pgl.glMatrixMode(ogl.GL_PROJECTION)
        pgl.glOrtho(-width / 8, width / 8, -height / 8, height / 8, 0, 500)
        pgl.glFlush()

        pgl.glViewport(500, 0, 650, 500)
        pgl.glLoadIdentity()
        pgl.glMatrixMode(ogl.GL_PROJECTION)
        Ratio = width/height
        # pgl.gluPerspective(self.dist, Ratio, 1, 1000)
        pgl.glOrtho(-width/8, width/8, -height/8, height/8, 0, 500)
        pgl.glFlush()
        pgl.glMatrixMode(ogl.GL_MODELVIEW)
        pgl.glTranslatef(0, 0, -100)

Window(WINDOW, WINDOW, 'Cube')
pyglet.app.run()

您能帮助解决这个问题吗?

设置视口和矩阵将修改OpenGL状态。之后,您必须立即画些东西。设置新的视口将覆盖先前的设置。像这样:

pgl.glClear(pgl.GL_COLOR_BUFFER_BIT | pgl.GL_DEPTH_BUFFER_BIT)

pgl.glViewport(0, 0, 650, 500)    
pgl.glMatrixMode(ogl.GL_PROJECTION)
pgl.glLoadIdentity()
pgl.glOrtho(-width / 8, width / 8, -height / 8, height / 8, 0, 500)
pgl.glMatrixMode(ogl.GL_MODELVIEW)
# set modelview matrix
# draw cube

pgl.glViewport(500, 0, 650, 500)
pgl.glMatrixMode(ogl.GL_PROJECTION)
pgl.glLoadIdentity()
# this is actually the same as before, so you can just leave it
pgl.glOrtho(-width/8, width/8, -height/8, height/8, 0, 500)
pgl.glMatrixMode(ogl.GL_MODELVIEW)
pgl.glTranslatef(0, 0, -100)
# set modelview matrix
# draw cube

这是针对OpenGL初学者的一般提示/提示/规则,它们会遇到以下问题:

在学习的过程中,在绘图功能之外不进行OpenGL调用!设置矩阵,视口等总是 进入绘图功能。
