A question in 3d model
Hello, the research I am doing needs to extract point coordinates of the surface of the 3D model. Is there any good method?
@igs2matlab, I think this depends a lot on the details of what you're trying to do, how the points, surfaces, etc are represented, etc.
@dengwirda , I am currently doing the calculation of space potential by finite difference method in three dimensions. The 3D models I know, such as OBJ or IGS, only contain the feature points of the model, but the coordinates of the surface points of the 3D model need to be extracted as the bottom boundary conditions in the research. The method i'm taking now is to project the surface of the 3D model into 2D, then use your algorithm to extract the 2D coordinates, and finally work out the 3D coordinates. What do you think of this?
