Witryna22 sie 2012 · The Extrinsic Camera Matrix. The camera's extrinsic matrix describes the camera's location in the world, and what direction it's pointing. Those familiar with OpenGL know this as the "view matrix" (or rolled into the "modelview matrix"). It has two components: a rotation matrix, R, and a translation vector t, but as we'll soon see, … Witryna5 lis 2016 · Andrea. 2,385 13 27.
