Abstract: Cloud-based real time rendering. For example, one embodiment of a system comprises: a first graphics processing node to perform a first set of graphics processing operations to render a graphics scene, the first set of graphics processing operations comprising ray-tracing independent operations; an interconnect or network interface coupling the first graphics processing node to a second graphics processing node; the second graphics processing node to receive an indication of a current view of a user of the first graphics processing node and to receive or construct a view-independent surface generated by view-independent ray traversal and intersection operations; the second graphics processing node to responsively perform a view-dependent translation of the view-independent surface based on the current view of the user to generate a view-dependent surface and to provide the view-dependent surface to the first graphics processing node; and the first graphics processing node to perform a second set of graphics processing operations to complete rendering of the graphics scene using the view-dependent surface.

Abstract: An apparatus and method to execute ray tracing instructions. For example, one embodiment of an apparatus comprises execution circuitry to execute a dequantize instruction to convert a plurality of quantized data values to a plurality of dequantized data values, the dequantize instruction including a first source operand to identify a plurality of packed quantized data values in a source register and a destination operand to identify a destination register in which to store a plurality of packed dequantized data values, wherein the execution circuitry is to convert each packed quantized data value in the source register to a floating point value, to multiply the floating point value by a first value to generate a first product and to add the first product to a second value to generate a dequantized data value, and to store the dequantized data value in a packed data element location in the destination register.

Abstract: Apparatus and method for context-aware compression. For example, one embodiment of an apparatus comprises: ray traversal/intersection circuitry to traverse rays through a hierarchical acceleration data structure to identify intersections between rays and primitives of a graphics scene; matrix compression circuitry/logic to compress hierarchical transformation matrices to generate compressed hierarchical transformation matrices by quantizing N-bit floating point data elements associated with child transforms of the hierarchical transformation matrices to variable-bit floating point numbers or integers comprising offsets from a parent transform of the child transform; and an instance processor to generate a plurality of instances of one or more base geometric objects in accordance with the compressed hierarchical transformation matrices.
