Abstract
Method, system, and computer-readable medium for emulating a point sprite represented by a three dimensional vertex in a cross platform environment. The system includes a three dimensional vertex representing a point sprite and a vertex and fragment shaders written in the first programming language. One or more variables are assigned to a set of points representing the 3D vertex using the vertex shader and convey information from the vertex shader to the fragment shader. The point sprite emulator translates the vertex and fragment shaders from the first programming language into a second programming language. The translation includes a transfer of each variable from the vertex shader to the fragment shader such that the information included in each variable is preserved. The point sprite is rendered from the 3D vertex using the translated vertex fragment shaders and displayed on a display screen.
