Abstract:
Back-facing patches of graphics objects are culled from tessellation using parametric tangent plane techniques extended to account for displacement of a simple mesh when establishing a complex mesh for rendering.

Claim (Index 1):
A device comprising:\n at least one compute circuit configured to receive data input and generate output, the circuit being configured to: receive data from at least one displacement map prior to tessellating graphics object patches with which the displacement map is associated; for at least a first patch of the graphics object patches: calculate four normals of the patch, one at each patch corner control point, using a cross product between the respective corner control point and control points of the patch that are nearest to the respective corner control point; using each normal, displace the control points of the patch that are nearest the respective corner control point according to data from the displacement map to create two new patches, one being positive displacement and one being negative displacement; determine whether any coefficient of either new patch's parametric tangent plane is front-facing; responsive to determining that a coefficient in either new patch is front-facing, tessellate the first patch; and responsive to determining that no coefficient in either new patch is front-facing, not tessellate the first patch.
