Abstract
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.
