System, method, and computer program product for rendering a screen-aligned rectangle primitive

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

• determining coordinates for a screen-aligned rectangle by projecting a specification line onto a screen-space plane, wherein the specification line is within a three-dimensional (3D) space;
• computing a plane equation associated with the specification line;
• and
• rasterizing the screen-aligned rectangle that is within the screen-space plane based on the coordinates and the plane equation,
• wherein the plane equation corresponds to a rendering parameter for the screen-aligned rectangle.

A system comprising:
