It allows to catch intersections with point OpenGL types. It uses shortest distance between the cast ray and geometry's vertices. In addition, it filters out the geometries whose primitive sets are different than GL_POINTS. The result primitive index is saved to hit.primitiveIndex.

Detailed Description
It allows to catch intersections with point OpenGL types. It uses shortest distance between the cast ray and geometry's vertices. In addition, it filters out the geometries whose primitive sets are different than GL_POINTS. The result primitive index is saved to hit.primitiveIndex.
