增强现实 - 3D 到 2D 点投影
此处和这里解释了如何通过特定位置和经度获取屏幕坐标,即 3D 到2D。我想通过投影矩阵学习同样的知识。我找到了很多材料,但在理解矩阵、它们如何工作等方面仍然存在问题。有人可以用简单明了的方式解释它,以便在我的脑海中得到一个图像吗?因为这一切在我脑子里都非常非常模糊。
提前致谢。
此致。
Here and here it is explained how to get screen coordinates by specific location and longitude, that is 3D to 2D. I want to learn the same with projection matrices. I've found a lot of materials, but still having problems to understand matrices, how they work etc. Can someone explain it in a plain and simple manner in order to get a picture in my head? Because it' is all very, very fuzzy in my head.
Thansk in advance.
Best regards.
