无法再添加三个立方体
having trouble adding three more cube
我正在尝试制作一个立方体,但我只能制作两个。如您所见,第三个立方体已损坏。我很难再制作三个立方体,因为我很难理解顶点和边。
我尝试在顶点中添加和删除数字,虽然有时面是正确的,但边缘是破损的。
有人可以帮我吗?
一个立方体网格完全足够了。绘制这个立方体 fife 次并使用 glTranslate
将立方体移动到世界上的不同位置。当前变换矩阵可以用glPushMatrix
和glPopMatrix
保存和恢复:
for i in range(5):
glPushMatrix()
glTranslate(-2+i, 0, 0)
