我制作了两个多维数据集视口,但它们都是正面正交投影,因此我需要从侧面看。
这是绘图代码
draw_small是小型静态立方体的绘图
dwar_big是可以移动,缩放和旋转的大立方体的图形

    def on_draw(self) :

        self.clear()

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

        pgl.glViewport(0, 0, 650, 500)
        pgl.glMatrixMode(pgl.GL_PROJECTION)
        pgl.glLoadIdentity()
        pgl.glOrtho(-1300 / 8, 1300 / 8, -1000 / 8, 1000 / 8, 100, 500)
        pgl.glMatrixMode(pgl.GL_MODELVIEW)
        pgl.glLoadIdentity
        pgl.glTranslatef(0, 0, -100)
        pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_FILL)
        draw_small()

        pgl.glPushMatrix()
        pgl.glTranslatef(self.x, self.y, self.z)
        pgl.glRotatef(self.xRotation, 1, 0, 0)
        pgl.glRotatef(self.yRotation, 0, 1, 0)
        pgl.glRotatef(self.zRotation, 0, 0, 1)
        pgl.glScalef(self.zoom, self.zoom, self.zoom)

        if not transparant:
            pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_FILL)
        else:
            ogl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_LINE)

        draw_big()

        pgl.glPopMatrix()


        pgl.glViewport(650, 0, 650, 500)
        pgl.glMatrixMode(pgl.GL_PROJECTION)
        pgl.glLoadIdentity()
        pgl.glOrtho(-1300 / 8, 1300 / 8, -1000 / 8, 1000 / 8, 0, 500)
        pgl.glMatrixMode(pgl.GL_MODELVIEW)
        pgl.glLoadIdentity()
        pgl.glTranslatef(0, 0, -100)
        pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_FILL)

        draw_small()

        pgl.glPushMatrix()
        pgl.glTranslatef(self.x, self.y, self.z)
        pgl.glRotatef(self.xRotation, 1, 0, 0)
        pgl.glRotatef(self.yRotation, 0, 1, 0)
        pgl.glRotatef(self.zRotation, 0, 0, 1)
        pgl.glScalef(self.zoom, self.zoom, self.zoom)

        if not transparant:
            pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_FILL)
        else:
            pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_LINE)

        draw_big()

        pgl.glPopMatrix()

最佳答案

只需将视图空间中的视图围绕y轴旋转90度即可:

pgl.glMatrixMode(pgl.GL_MODELVIEW)
pgl.glLoadIdentity
pgl.glTranslatef(0, 0, -100)
pgl.glRotatef(-90, 0, 1, 0) # roatet 90 degrees around view space y axis


注意,左视图和右视图由pgl.glRotatef(-90, 0, 1, 0)pgl.glRotatef(90, 0, 1, 0)生成。
顶视图和底视图是通过围绕视图空间x轴旋转分别通过pgl.glRotatef(90, 1, 0, 0)pgl.glRotatef(-90, 0, 1, 0)来实现的。
