20140125686 | IMAGE RENDERING METHOD AND SYSTEM - An image rendering method is provided, comprising comparing a current image frame with a previous image frame to detect a dynamic change in an object in the image frames, with each image frame being defined by a scene graph and each object having an associated geometric bounding volume. If a dynamic change in an object is detected, the method comprises rendering the object's geometric bounding volume to a stencil buffer for each dynamically changed object, using a stencil value assigned to the current image frame. A stencil is then applied to determine areas in the frames having non-zero stencil values. The method further comprises clearing a color buffer with respect to the areas in the previous image frame that have been redrawn and with respect to areas in the current frame that need to be overdrawn, rendering the image frame to the color buffer using a stencil test, so that only the areas with non-zero stencil values are redrawn, and then removing the stencil values from a previous image frame from the stencil buffer. | 05-08-2014 |
