20130307852 | SYSTEM AND METHOD FOR CALCULATING MULTI-RESOLUTION DYNAMIC AMBIENT OCCLUSION - A system and method for generating a three-dimensional image is provided. An embodiment of the present invention includes calculating the ambient occlusion at a vertex in multiple, independent stages. Determining the global AO at the vertex may be performed using a first technique. Determining the local AO at the vertex may be performed using a second technique. The total AO can be found as a function of the local AO and global AO. | 11-21-2013 |
20100045676 | SYSTEMS AND METHODS FOR FAST REAL-TIME RENDERING OF MULTIPLE LIGHT SOURCES - Example embodiments of the present invention include systems and methods for the efficient rendering of multiple light sources, each controlled individually, in a single pass. An example embodiment encodes the light sources in a texture map, such as DXT. Each channel of the multi-channel texture map encodes data associated with a light source. The pixel shader then renders multiple light sources according to the multiple channels of the texture. Additionally, the pixel shader may render multiple textures, and thus render an even greater number of individual light sources. In a further embodiment, the rendering of a plurality of individually controlled light sources is accomplished in a single pass. | 02-25-2010 |
20100045675 | SYSTEMS AND METHODS FOR REPRODUCTION OF SHADOWS FROM MULTIPLE INCIDENT LIGHT SOURCES - Systems and methods are provided for simulating shadows in a scene. In an embodiment, two or more light sources that cast shadows from objects are identified. Each of those light sources is then assigned to a channel in a shadow mask buffer. The shadows are then accumulated into the shadow mask buffer and may be combined with corresponding lights to render the scene. | 02-25-2010 |
20100045669 | SYSTEMS AND METHOD FOR VISUALIZATION OF FLUIDS - Example embodiments of the present invention are directed to methods and systems for simulating and visualizing a flowing fluid when interacting with an intersecting object. An example embodiment provides for simulating the falling fluid as a two-dimensional plane and rendering first and second depth buffers corresponding to current depth information for, respectively, a top surface and a bottom surface of the object. The values of first and second current simulation textures are rendered for the top and bottom surfaces of the object, where for a given frame each of the first and second current simulation texture values is set to either a corresponding value of the first or second depth buffer or a corresponding, velocity-offset value of the previous frame's first or second simulation texture respectively. A visible fluid mesh is rendered in the two-dimensional plane based on the current simulation textures. | 02-25-2010 |
