A straightforward C++ openFrameworks addon to check if a 3D point (ofVec3f) is inside a closed 3D ofMesh. To determine this, it uses the Möller–Trumbore ray-triangle intersection algorithm.
Use ofxPointInMesh's static method by passing a point and a mesh as arguments:
bool isInside = ofxPointInMesh::isInside(thePoint, theMesh);Also see the examples. Project files for Windows Code::Blocks are included. You can use openFrameworks' ProjectGenerator to generate project files for other IDE's.
