How to measure length between the two mouse cursor? about smpl-anthropometry HOT 2 CLOSED

Hi, sorry for the late reply!

To measure the distance between two arbitrary points A and B on the body, you could do:

1. something like this where they follow the shortest path along the edges between two vertices of the mesh:
   • Find the closest mesh vertices on the body to A and B
   • find their distance between these vertices using the code
   • add the distance from the mesh vertices and the points A and B
2. something similar to the measure_circumference in measure.py:
   • define a plane with three points: points A and B, and a third random point (would be better if this third point was on the "opposite" side of the body than the first two)
   • use the trimesh.intersections.mesh_plane to find the slice segments between the plane and mesh
   • use the segments to find your distance
   • you could first find the closest point in the segments to point A
   • then start from this point and iteratively find the next closest segment, forming a loop measurement until you reach the closest segment to point B
   • Note1: you need to define a method to know if you're measuring from A to B or from B to A
   • Note2: points A and B might be on a segment, so if you need a precise measurements, take that into consideration
   • Note3: if you slice the body with a plane, you can get multiple slices - you should know the region of your measurement so you can eliminate the unnecessary slices
