EmbreeΒΆ

  • Requires Embree library by Intel.

  • Requires cnpy.

  • Can be compiled using CMake. Relevant CMakeLists.txt is provided.

  • C++ 11 standard minimum required.

  • Outputs *.npz archive in numpy binary archive format, which could

be imported.

Psuedocode:

  • Declare device, scene, geometry, vertex buffer, index buffer

  • Import coordinates, centroids.

  • For each element, pass vertices and indices

  • Then commit geometry, attach geometry to scene.

  • Release geometry.

  • Commit scene for all.

  • Define ray

  • Loop over all elements twice, define ray origin and direction.

  • Define intersect, compare geometry and release scene, device.

The above steps provide a quick summary.
