The method includes the steps of receiving a three-dimensional (3D) model, receiving a set of probes, where each probe specifies a location within the 3D model and an orientation of the probe, and performing, via a processor, a lighting simulation based on the 3D model, the set of probes, and one or more light path expressions. The light path expressions are regular expressions that represent a series of events, each event representing an interaction of a ray at a location in the 3D model.

Abstract: Techniques to patch a shader program after the shader has been compiled and/or while the shader is in an execution pipeline are described. The shader may be patched based on references to global constants in a global constant buffer. For example, the reference to the global constant buffer may be patched with the value of the global constant, conditional statements based on references to the global constant buffer may be replaced with unconditional statements based on the value of the global constant in the global constant buffer, to optimize the shader or increase computational efficiency of the shader.

Abstract: Concepts and technologies are described herein for providing raster-based mesh decimation. Generally described, input data defining a model is processed to render the model as a depth map from a multitude of perspectives. By capturing depth map data from a multitude of perspectives, components of the model that are visible from the multitude of perspectives are captured in the depth map data and components that are blocked by the visible components are not captured in the depth map data. Point cloud data is generated by merging the depth map data captured from the multitude of perspectives. Output mesh data is generated by applying a surface reconstruction to the point cloud data. One or more mesh decimation algorithms may be applied to the mesh data. Image data may also be captured from the input data and applied to the output mesh data.

Abstract: An apparatus and a method for generating 3-dimensional computer graphic images. The image is first sub-divided into a plurality of rectangular areas. A display list memory is loaded with object data for each rectangular area. The image and shading data for each picture element of each rectangular area are derived from the object data in the image synthesis processor and a texturizing and shading processor. A depth range generator derives a depth range for each rectangular area from the object data as the imaging and shading data is derived. This is compared with the depth of each new object to be provided to the image synthesis processor and the object may be prevented from being provided to the image synthesis processor independence on the result of the comparison.

Abstract: Techniques for controlling patch-usage in image synthesis are described. In implementations, a curve is fitted to a set of sorted matching errors that correspond to potential source-to-target patch assignments between a source image and a target image. Then, an error budget is determined using the curve. In an example, the error budget is usable to identify feasible patch assignments from the potential source-to-target patch assignments. Using the error budget along with uniform patch-usage enforcement, source patches from the source image are assigned to target patches in the target image. Then, at least one of the assigned source patches is assigned to an additional target patch based on the error budget. Subsequently, an image is synthesized based on the source patches assigned to the target patches.
