intersect and delete 3D Mesh
显示 更早的评论
Hi,
I'm trying to optimize a plotted 3D geometry by 'cutting' it with a differnt geometry. The Idea is to identify the intersecting parts of it and delete these. Does anyone know if this is possible? And if so how? The first geometry is a pyramid frustum and the second, which is going to be the cutting one, is a cylinder.
Let me know if theres a need of code, more infos or sth, im kinda new here :)
Cheers

What is the form of the 3D geometry?
Is it an external file like .stl? or do you simply have the data points for the geometry? or something else?

Hi @Alexander. This is known as constructive solid geometry (CSG). Here are a few MATLAB resources for you.
- gptoolbox on File Exchange contains two functions, mesh_boolean and mesh_boolean_winding_number.
- Iso2Mesh on File Exchange contains the surfboolean function.
- GEOMLib on File Exchange is a library for 3D CSG.
- Surface Booleans on File Exchange gives a demonstration of CSG, but actively recommends Iso2Mesh over their code.
