PyOpenGL我如何导入obj文件？

            glColor3fv(colors[x])

    glEnd()

def main():
        pygame.init()
        display = (800, 600)
        pygame.display.set_mode(display, DOUBLEBUF | OPENGL)
        gluPerspective(45, (display[0] / display[1]), 1, 500.0)

                    pygame.quit()
                    quit()

                if event.type == pygame.KEYDOWN:

            glRotatef(1, 5, 1, 1)
            glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
            Cube()
            pygame.display.flip()
            pygame.time.wait(10)

main()

现在，我想将场景与多维数据集一起添加到我的窗口中，或将其替换为任何东西

有人可以告诉我如何做到这一点吗？

找不到有关如何在opengl和pygame中正确使用wavefront的太多信息>

opengl编程的新手

所以我想我必须从场景中添加新的顶点吧？

我现在想添加obj，以了解如何将Blender模型导入游戏中

谢谢

import pygame从pygame.locals导入OpenGL *从OpenGL.GL导入*从OpenGL.GLU导入*导入pywavefront scene = pywavefront.Wavefront（'Handgun_obj.obj'）顶点=（（（-1，-1，-1） ，...

当您读取collect_faces = True时，设置关键字参数Wavefront .obj file。这导致为每个网格收集三角形面数据。（请参见PyWavefront）
