I apologize in advance if this is addressed in a tutorial or forum or this shouldn't be asked here but I've been searching for hours and haven't found it.
Is it possible to reconstruct a surface from X,Y,Z points (unstructured point cloud) to triangle mesh with G3Sharp?

Hy,

thx for sharing this demos. 😀

I don't find a demo how to use the method "MeshExtrudeMesh()" may you can add it?

Thx & Regards

First, it looks like you have a great library here, thanks for all your work! I have the following data defining an isosurface mesh from another program and would like to build a mesh for spatial queries (e.x. ray intersection):

• Vertices: float[n, 3] where n = number of vertices and each row holds the coordinate of a vertex [x y z]
• Triangles: int[n, 3] where n = number of triangles and each row holds three indices to the vertices array
• Normals: float[n, 3] row holds the orientation [x y z] of a normal and corresponds to a vertex with the same row index

How do I efficiently create a DMesh3 from this data? I assume that I then want to pass this DMesh3 to an instance of DMeshAABBTree3 in order to perform efficient ray intersection queries. Is this correct?

Ultimately, the problem I would like to solve is computing the relative radial position of a point inside the isosurface. Ex: radial = dist(center, point) / dist(center, edge) where center is the isosurface center of mass (already computed), point is a query point, and edge is the point on the isosurface that lies on the ray (center, point).

This may be a stupid question but how to run this demo with Unity?
