A system and a method for rendering data associated with a 3-D scene description are provided. The system includes a graphics processing unit configured to operably communicate with a communications bus. The graphics processing unit is further configured to receive the 3-D scene description from the communications bus and to generate a 3-D image data set comprising at least a first 2-D data field based on the 3-D scene description. The graphics processing unit is further configured to transmit the 3-D image data set through the communication bus.

System and method for rendering data associated with a 3-D scene description

A system and a method for generating dithering patterns associated with a digital image are provided. The method includes generating a first table index value indicative of a location in a first table where first, second, and third color intensity values associated with a plurality of pixels on the display device are stored. The method further includes transmitting the first table index value from a computer to a second device via a communication bus. The method further includes accessing the first table using the first table index value to obtain the first, second, and third color intensity values associated with the plurality of pixels, the accessing being performed by the second device. The method further includes generating first, second, and third dithering patterns associated with the plurality of pixels based on the first, second, and third color intensity values, respectively, and position values indicative of positions of the plurality of pixels.

A graphics memory system for managing image data for a volumetric display that displays volumetric images, the system including a first buffer memory with a first predefined address space for holding image data for a three-dimensional image; a second buffer memory with as second predefined address space for holding image data for a three-dimensional image, wherein the first and second predefined address spaces are the same; and a voxel router in communication with both the first and second buffer memories, wherein the voxel router is configured to use a selectable one of the first and second buffer memories as an active memory out of which stored image data is to be read for display on the volumetric display and to use the other of the first and second buffer memories as an inactive memory into which image data is to be written.
