System, method, and computer program product for shading using a dynamic object-space grid

A system comprising:

• a processing pipeline that is configured to:
• receive an object defined by a plurality of triangle primitives in a three-dimensional (3D) space that is specific to the object;
• define an object-space shading grid for at least one of the plurality of triangle primitives based on coordinates at vertices of the at least one triangle primitive in the 3D space,
• wherein a shape of an object-space shading element corresponds to a shape of the at least one triangle primitive, wherein the object-space shading grid comprises at least one object-space shading element;
• and
• execute a shader program to compute a shaded value at a point on the object-space shading grid for a first triangle primitive.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, causes the processor to perform steps comprising:

• receiving an object defined by a plurality of triangle primitives in a three-dimensional (3D) space that is specific to the object;
• defining an object-space shading grid for at least one of the plurality of triangle primitives based on coordinates at vertices of the at least one triangle primitive in the 3D space,
• wherein a shape of an object-space shading element corresponds to a shape of the at least one triangle primitive, wherein the object-space shading grid comprises at least one object-space shading element;
• and
• executing, by a processing pipeline, a shader program to compute a shaded value at a point on the object-space shading grid for a first triangle primitive.
