Image forming techniques

A computer-readable medium that stores instructions, which when executed by a computer, cause the computer to:

• generate a patch based on stored domain points, wherein to generate, the computer is to:
• retrieve encoded domain points of an inner tessellation of the patch from one of an even or odd factor tessellation table,
• convert encoded domain points to the [0,1] domain, and
• retrieve indexes of triangle corners;
• and
• provide the patch for display.

A system comprising:

• a display;
• and
• a computing system to generate patches to transmit to the display, wherein the computing system comprises:
• a tessellator to generate a patch, wherein to generate a patch, the tessellator is to retrieve domain points of a patch, wherein to retrieve domain points, the tessellator is to retrieve domain points of an inner tessellation from one of an odd or even table;
• and
• a domain shader to convert domain points to a [0,1] domain and to generate a three dimensional point on the patch.
