Ray Intersect box
Relation constraint plugin which adds two nodes:
Determine intersection point from the ray and polygonal mesh. To the input node of the box parameters are polygonal mesh and a ray points, the output are a point of intersection and texture coordinates. Box is in developing stage.
Node allows to translate from the cartesian coordinates system into the spherical coordinates, as well as return u, v coordinates from virtual projected sphere. Additionally, you can also specify an input object, a transformation which will be used as a coordinate reference system to calculate the spherical coordinates.
