Mesh 를 다룰 때 pytorch3d, open3d 두가지의 3d 라이브러리를 많이 쓰는 편이다. Triangle Mesh 가 있는 상황에서 Point Cloud를 뽑아내는 두 라이브러리 함수를 정리해 놓았다. 1. Open3D의 Sampling http://www.open3d.org/docs/release/tutorial/geometry/mesh.html#Sampling Mesh — Open3D 0.17.0 documentation Open3D has a data structure for 3D triangle meshes called TriangleMesh. The code below shows how to read a triangle mesh from a ply file and print its v..

나중에 실 사용을 위해서 적어둔 글입니다. Two matrix modes usually used Conversion 1. GL_MODELVIEW (default) - Camera Matrix (Extrinsic) It is a combination of view conversion and model conversion. View Conversion used by (gluLookAt) gluLookAt(eyeX, eyeY, eyeZ, centerX, centerY, centerZ, upX, upY, upZ) # eyeX, eyeY, eyeZ : viewer # centerX, centerY, centeZ : where viewer looking at # upX, upY, upZ : camera coordi..
