    摘要： Techniques for generating a stereo image from a single set of input geometry in a three-dimensional rendering pipeline are disclosed. Vertices are processed through the end of the world-space pipeline. In the primitive assembler, at the end of the world-space pipeline, before perspective division, each clip-space vertex is duplicated. The primitive assembler generates this duplicated clip-space vertex using the y, z, and w coordinates of the original vertex and based on an x coordinate that is offset in the x-direction in clip-space as compared with the x coordinate of the original vertex. Both the original vertex clip-space vertex and the modified clip-space vertex are then sent through the rest of the pipeline for processing, including perspective division, viewport transform, rasterization, pixel shading, and other operations. The result is that a single set of input vertices is rendered into a stereo image.

    摘要： A computer system for managing multiple distinct perspectives within a mixed-reality design environment loads a three-dimensional architectural model into memory. The three-dimensional architectural model is associated with a virtual coordinate system. The three-dimensional architectural model comprises at least one virtual object that is associated with an independently executable software object that comprises independent variables and functions that are specific to a particular architectural element that is represented by the at least one virtual object. The computer system associates the virtual coordinate system with a physical coordinate system within a real-world environment. The computer system transmits to each device of multiple different devices rendering information. The rendering information comprises three-dimensional image data for rendering the three-dimensional architectural model and coordinate information that maps the virtual coordinate system to the physical coordinate system.

    摘要： The invention is a system and method of compressing terrain data to be used to render a three-dimensional map representation of the terrain data. In general, the invention operates by first selecting the boundaries of the terrain data and to be compressed and dividing the terrain data into regular geometric areas. Next, a type of free-edged, planar geometric surface is defined which is used to approximate the terrain data for each regular geometric area. The approximations are checked to determine if they fall within user selected tolerances. If the approximation for a specific regular geometric area is within the user specified tolerances, the data is saved for that specific regular geometric area. If the approximation for a specific regular geometric area falls outside the user specified tolerances, the regular geometric area is divided and a free-edged, planar geometric surface approximation is made for each of the divided areas. This process is recursively repeated until all of the regular geometric areas are approximated by free-edged, planar surfaces. Finally, the compressed terrain data is used to render a three-dimensional map.

    摘要： The disclosure provides an approach for rendering heterogeneous polydisperse granular media. In one aspect, a rendering application renders such granular media using a combination of explicit path tracing and accelerated path construction using proxy path tracing, shell tracing, and volumetric path tracing. In proxy path tracing in particular, the rendering application instantiates proxy geometry in the form of a bounding sphere and determines internal scattering in the grain using a precomputed grain scattering distribution function that relates incident and outgoing radiance functions on the bounding sphere. In shell tracing, the rendering application uses shells to aggregate many grain interactions into a single step. The rendering application derives a continuous liquid/volume equivalent to the granular material based on the material's optical properties and selects a precomputed shell transport function (STF) to use from a database by interpolating nearby database entries using radiative transfer equation (RTE) parameters at the shell's center.
