System And Method For Creating Real-Time Shadows Of Complex Transparent Objects
US Patent:
6646640, Nov 11, 2003
Filed:
Feb 6, 2001
Appl. No.:
09/778183
Inventors:
Gabor Nagy - Foster City CA
Assignee:
Sony Computer Entertainment Inc. - Tokyo
International Classification:
G06T 1560
US Classification:
345426, 345427, 345582, 345421
Abstract:
A system and method for creating real-time shadows of complex transparent objects includes a processor and a main memory that stores a transparent blocker object and a receiver object. A light source in a three-dimensional game environment determines an origin of a light coordinate system. A unit vector from the light source to the blocker object defines a z-axis of the light coordinate system and defines a light vector. The processor converts vertices of the blocker object from world coordinates into light coordinates. A graphics processor then calculates a shadow map by taking the dot-product of the light vector and each vertex of the blocker object. The shadow map is then stored in a memory of a graphics processor and is applied as a texture map to the receiver object by the graphics processor.
Method And Apparatus For Real-Time Global Illumination Incorporating Stream Processor Based Hybrid Ray Tracing
US Patent:
7212207, May 1, 2007
Filed:
Aug 20, 2003
Appl. No.:
10/645819
Inventors:
Robin J. Green - Redwood City CA, US
Gabor Nagy - San Mateo CA, US
Gabor Nagy - San Mateo CA, US
Assignee:
Sony Computer Entertainment Inc. - Tokyo
International Classification:
G06T 15/60, G09G 5/00
US Classification:
345426, 345582
Abstract:
A method for calculating a lighting function for an object to be rendered using a basis function is provided. The method includes calculating a transfer function approximation of the lighting function through a stream processor. A method for presenting lighting characteristics associated with a display object in real-time and a method for determining secondary illumination features for an object to be displayed are also provided. A computer readable medium and a computing device having a graphics processing unit capable of determining lighting characteristics for an object in real time are also included.
Texturing In Graphics Hardware
US Patent:
2012028, Nov 8, 2012
Filed:
May 2, 2011
Appl. No.:
13/099281
Inventors:
Gabor Nagy - San Mateo CA, US
Assignee:
Sony Computer Entertainment Inc. - Tokyo
International Classification:
G06T 15/00
US Classification:
345419
Abstract:
Methods, systems, and devices for rendering computer graphics using texture maps are disclosed. Multiple texture maps with disparate data types, such as a mix of integer data types for RGB colors and floating point data types for XYZ normal vector components, are passed as one texture map set to a graphics processing unit (GPU). Filter parameters and other interpolation parameters are re-used between the disparate texture maps. A user can specify a number of integer and floating point-based channels for processing at one time by the GPU, thereby customizing a texture set structure.
