Projection

Projection enum

When a mapping primitive, like a plane, sphere, box, or cylinder, is used, there are two projection options. If m_type = srfp_mapping, then m_projection is ignored.

Derived Classes:

Namespace: Rhino.Render
Projection: references

Values (3)

None = 0

None

ClosestPoint = 1

ClosestPoint: world xyz maps to the point on the mapping primitive that is closest to xyz. In this case, ON_TextureMapping::Evaluate ignores the vector argument.

Ray = 2

Ray: world xyz + world vector defines a world line. The world line is intersected with the mapping primitive and the intersection point that is closest to the world xyz point is used to calculate the mapping parameters.
