GetRGB()

RGBColor GetRGB ( const Vector3D &  position, const Vector3D &  normal, const Vector3D &  uvw  )

overridevirtual

Retrieves the RGB color at a given 3D position using UV mapping.

Parameters

position	3D position in the scene.
normal	Normal vector at the position (not used in UV mapping).
uvw	UV texture coordinates at the position.

Returns

The RGB color sampled from the image at the given UV coordinates.

Reimplemented from Image.
