摘要： Techniques for improving the performance of vector-based, fluid motion simulation techniques in procedural painting algorithms. The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic and serendipitous behaviors of watercolor painting at good interactive rates even on relatively low-powered devices. The techniques may include resampling the vertices of pigment polygons after growth at least at some iterations of the algorithm to provide smoother, more uniform growth; rasterizing dried pigment polygons into a texture so that the dried polygons are not rendered at each iteration of the algorithm; and rendering only a subset of live pigment polygons at each iteration of the algorithm. Polygons used by the techniques may be separated into static water polygons and dynamic pigment polygons.

摘要： Methods and apparatus for simulating fluid motion using procedural shape growth. In a vector-based, fluid motion simulation technique, fluid location may be defined by groups of one or more polygons deposited on a digital canvas. Two or more polygons may overlap. The polygons may be semitransparent. To simulate fluid motion, vertices that specify the edges of each deposited polygon are independently moved. By moving the vertices, a polygon may grow, and fluid motion effects may be simulated, including but not limited to directional flow and blending effects. A randomization technique may be applied to the movement at each vertex to simulate the non-uniform spreading of fluids. Overlapped polygons may be blended with overlapping polygons to simulate the mixing of fluids. The technique may be applied, for example, in watercolor painting simulation, where groups of one or more polygons are deposited using brush strokes.

摘要： Anti-aliased output based on a scene comprising a plurality of objects may be generated. In one embodiment, a number of samples for an anti-aliasing operation is determined. For each of the samples: each of the objects may be translated in space according to jitter values; the objects may be multiplied by a fractional alpha value for the respective sample; a fractional alpha value stored in a buffer may be modified by a transparency value for each transparent object; and the objects may be rendered to the buffer by blending the objects with existing contents of the buffer. The fractional alpha values may vary from sample to sample. In one embodiment, the plurality of objects comprises one or more opaque objects and one or more transparent objects. In one embodiment, the objects may be rendered directly to a screen buffer.

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： A system and method for rendering with an object proxy. In one embodiment, a method includes forming a set of view textures corresponding to a set of viewing directions; selecting a viewing direction for rendering; selecting at least two view textures from the formed set based on the selected viewing direction; and rendering the object proxy at the selected viewing direction. The rendering step includes applying texture from the selected view textures onto the selected object proxy. The view texture set forming step includes: calculating texture coordinates for the object proxy based on the level of obstruction at different portions of the object proxy and texture packing data; and drawing portions of the object based on the level of obstruction data for the object proxy and based on the texture packing data to obtain a view texture at the selected viewing direction.

摘要： Techniques for improving the performance of vector-based, fluid motion simulation techniques. The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic, serendipitous behaviors of painting at good interactive rates even on relatively low-powered devices. Instead of employing polygons in a procedural painting algorithm that are combinations of pigment and water, a technique may be employed in which the polygons are separated into pigment polygons and water polygons. The water polygons are not rendered; only the pigment polygons are rendered. To improve the performance of the wetness determination at vertices of the pigment polygons, a technique may be used that first rasterizes all of the water polygons into a buffer, which may be referred to as a wetness layer or wetmap; the wetness at a vertex is then determined by sampling this buffer or layer at the vertex's position.

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.
