Property Documentation

OpenMayaRender.MIntersection.barycentricCoordinates

static

 Get the barycentric coordinates (a, b). Only valid for triangles.
 Follows Tomas Moller & Ben Trumbore, jgt 97 "Fast minimum storage ray/triangle intersection" which means that a point, T(a,b), on a triangle is given by: 
    T(a,b) = (1-a-b)V0 + aV1 + bV2
 where V0, V1, and V2 are the triangle vertices.

OpenMayaRender.MIntersection.edgeInterpolantValue

static

 The edge interpolant value. Only valid for edges.
 It corresponds to the intersection position on the edge, from 0 to 1 starting at V0 going to V1.

OpenMayaRender.MIntersection.index

static

 The index of the hit vertex, edge or triangle.
 It is the position in the index buffer of the render item geometry when provided, and the position in the vertex buffer if not.

OpenMayaRender.MIntersection.instanceID

static

 The draw instance ID of the render item. Only valid for instanced render items.

OpenMayaRender.MIntersection.intersectionPoint

static

 The intersection point.

OpenMayaRender.MIntersection.selectionLevel

static

 The selection level of the intersection.
 See MSelectionContext::selectionLevel for list of valid level values.
