Abstract: A graphical rendering system and method is disclosed which stores generated and calculated path parameters along the entire user drawn path. These stored parameters are then editable or otherwise filtered at any point so as to create for the user different effects without the necessity of redrawing any portion of the path. Color changes or blends can be created along the length of the path or at any specific segment such as overdraws where the color is darker due to the overdraw. The system and method allow for changing of pen type and for giving different weights to certain of the stored parameters depending upon the currently selected pen type, color choice, light source shading, or desired rendered media.
