摘要： Systems, methods, and computer-readable storage media for rendering three-dimensional scenes including transparent surfaces are described, including two techniques for efficient rendering of transparent surfaces that exploit partial ordering in the scene geometry. The first (hybrid layer peeling) may combine unordered meshes with ordered meshes in an efficient way, and may be well suited for rendering scenes such as volumes with embedded transparent meshes. The second (coherent layer peeling) may efficiently detect and render correctly sorted fragment sequences for a given pixel in one iteration, allowing for a smaller number of passes than traditional depth peeling. Pre-sorting and/or periodic sorting of some or all of the surfaces in a scene may be performed, but perfect sorting may not be required. The methods may be implemented in hardware, software, or a combination thereof, such as by program instructions executable on one or more CPUs and/or GPUs.

摘要： Systems and methods for rendering a gaseous display. The distance from a user's reference point to each pixel through the gas is determined. The distance is then converted into an attenuation factor that is used to blend the scene color with the gas color. The result can then be used to simulate patchy fog, clouds, or other gases of more or less constant density and colors.

摘要： The present invention provides an improved system and method for rendering shadows in a computer graphics system. Textures representing the area of influence resulting from a combination of light sources and shadow casters are pre-computed. Scenes are then rendered using the pre-computed textures. A first step entails generating sets of directions and associated pre-computed textures for each light source and shadow caster pair in a simulation frame. Next, a first scene in the simulation is rendered. During this step one or more of the pre-computed textures are used to darken the area of influence or shadow portion of the scene.

摘要： Methods and apparatus for procedural modeling are described for generating procedural models and exploring procedural model space. Common procedural components (models, modules, and methods) and a hierarchical framework are described that may be used to construct hierarchical procedural models. A model may comprise a hierarchy of one or more modules. Each module includes a sequence of methods and an optional geometry for display. A method may be controlled by one or more parameters. The values of the parameters may be specified via curves. A module description may be condensed into a single array of values for parameters of the module. Thus, a model or module may be specified by filling in values for arrays of parameters for the sequence of methods. An interpolation technique for interpolating between models is described in which models are matched according to a cost function so that ancestry is preserved.

摘要： Method and apparatus for synthesizing element arrangements from an example. Embodiments may synthesize element arrangement patterns from an example arrangement. Embodiments may combine a texture synthesis technique based on local neighborhood comparison of an example and a target with procedural modeling based on local growth. Given an example, connectivity of elements may be constructed to get neighborhoods information of each element. A synthesis process may start with a single seed and expand the synthesized pattern by placing new elements at seed locations one by one. A reference element may be selected from the example that has neighborhood features that are most similar to neighborhood features of the target seed in the synthesized pattern. A non-rotation mode, a rotation mode, and a flow field mode may be provided. A painting tool, a flow field tool, and a boundary tool may be provided.

摘要： Methods and apparatus for improving printability of a three-dimensional model are disclosed. For a computer-based three-dimensional model to be generated by a three-dimensional printing system, a three-dimensional printability analysis of the model is performed. The three-dimensional printability analysis applies one or more test cases representing forces that may be applied to the model. The three-dimensional printability analysis generates one or more points at which stresses associated with the test case exceed the structural tolerances of a material to be used by the three-dimensional printing system for a fabrication of the model. For each point of the one or more points, one or more corrections to the model designed to decrease the stresses associated with a respective test case are calculated. For each test case, the corrections are evaluated. The evaluating includes selecting a preferred correction based on one or more criteria.
