我想绘制和显示矩形立方体的边或边,但仍然没有成功使用WPF。它位于用户控件中,我想在Windows窗体(c#)应用程序中显示。正如我所看到的,WPF中的3D对象是用三角形制作的,所以我尝试使用矩形绘制线条,其中矩形的宽度很小(足以识别为立方体的边或侧),但不显示正确。这里是我使用的代码:试图在WPF中绘制矩形立方体的边缘,但不成功

我想着尝试其他图形库,如opengl或gdi +。如果您知道如何在wpf中绘制3D线,那么请举例说明。任何帮助将不胜感激。提前致谢。
矩形立方体?你的意思是直角棱镜吗? – bouvierr 2012-04-03 22:14:26
你想绘制一个对象的线框? – ChrisF 2012-04-03 22:15:03
我编辑了帖子。只有我想看到的物体的边缘或边缘。我不想绘制完整的对象或可见的面,只有对象的边框或边/边。 – mj1261829 2012-04-03 22:25:29
