ALE3D asks

[rhornung67]

ALE3D folks are interested in several new things in Axom (some of which are already in the development plan). Some follow-up is needed to refine requirements and use cases.

• Port octree to run on GPUs, which would make STL shaping run on the GPUs. We would benefit from that, since right now STL shaping is using OpenMP CPU threading in the GPU builds.
• Geometric primitives that would enable GPU support for 2D ProE shaping (intersection of a tetrahedron with a plane, volume of intersection of a polygon with a quadrilateral, etc.)
• Look into an isosurface detection method that we use in DSD (mesh crossing points) and how it compares to the marching cubes method in Axom. We might be able to replace what we have with marching cubes or they might be able to implement this other method for us.
