Abstract: A method, apparatus, system, and computer program product provide the ability to render a line having line stylization/linetype pattern via texture mapping of a graphics processing unit (GPU). Linetype information for a pattern of a linetype for the line is acquired. The pattern is stored in a texture by encoding a type of element of the pattern and a texel center location. The GPU renders the line by computing a distance between a pixel of the line and the texel center location, determining if the distance exceeds a threshold, and rendering the pixel if the distance is within the threshold.
