I'm curious about the optimal method for creating a custom 3D polygon using an array of 3D points in three.js. This polygon doesn't have any holes and the points are arranged in a way that they connect to adjacent vertices smoothly. I've been able to achieve this in 2D, but I'm looking for a solution that prevents coplanar vertices. Any suggestions or guidance on accomplishing this would be greatly appreciated! Thank you.
One of the key challenges at hand involves transforming a set of points into a 3D mesh by determining how to connect the vertices to form triangles.
This task may seem unexpectedly intricate, given the existence of numerous scientific publications, libraries, and resources dedicated to it.
Fortunately, in this scenario, the process is somewhat simplified as you have an idea of how the vertices should be interconnected. I suggest exploring options such as the earcut-library or libtess.js, which are capable of generating the required triangulations.
Once you have achieved the triangulation, you can follow @lior-trau's guidance on creating the geometry based on the obtained result.
Although this question is quite old, those seeking an answer like I was may want to consider using ConvexGeometry or ConvexHull
