摘要： A three-dimensional (3D) rendering method includes extracting sample points from a 3D scene, acquiring rendering result information for the sample points by rendering the sample points, and generating a rendering result image corresponding to an entire rendering based on the rendering result information for the sample points and feature information of the 3D scene.

摘要： One aspect of the disclosure provides a method for rendering an image. The method includes: placing primitives of the image in a screen space; binning the primitives into tiles of the screen space that the primitives touch; and rasterizing the tiles at one tile of the tiles at a time. The aforementioned rasterizing includes shading a subset of the primitives binned to the one tile at a first shading rate during a first pass and shading the subset of primitives binned to the one tile at a second shading rate during a second pass, the second shading rate is different from the first shading rate, and the aforementioned placing is performed once while the image is rendered.

摘要： This disclosure describes techniques for executing shader programs in a graphics processing unit (GPU). In some examples, the techniques for executing shader programs may include executing, with a shader unit of a graphics processor, a shader program that performs vertex shader processing and that generates multiple output vertices for each input vertex that is received by the shader program. In further examples, the techniques for executing shader programs may include executing a merged vertex/geometry shader program using a non-replicated mode of execution. The non-replicated mode of execution may involve assigning each of a plurality of primitives to one merged vertex/geometry shader program instance per primitive and causing each of the instances to output a plurality of vertices. In additional examples, the techniques for executing shader programs may include techniques for selecting one of a non-replicated mode and a replicated mode for executing a merged vertex/geometry shader program.

摘要： A model generator 2 arranges a three-dimensional model on a base line. A model renderer 4 renders the three-dimensional model. A distance map generator 5 converts each depth of the three-dimensional model rendered into a distance from the base line. An alpha map generator 7 converts the distance from the base line into an alpha value.

摘要： Techniques for performing clipping of graphics primitives 60 with respect to a clipping boundary 65 are described. The clipping step 10 may be performed separately for each tile of a graphics frame to be rendered, after a primitive list for the tile has been read from a primitive memory 38. Clipping may be performed only for larger primitives whose size exceeds a given threshold. Clipping of a primitive 60 to the clipping boundary 65 may be performed inexactly so that only a single clipped primitive is generated which may extend beyond the clipping boundary. A clipped primitive generated by clipping may be used for a depth function calculation of a primitive setup operation and not for an edge determination.

摘要： In various examples, shader bindings may be recorded in a shader binding table that includes shader records. Geometry of a 3D scene may be instantiated using object instances, and each may be associated with a respective set of the shader records using a location identifier of the set of shader records in memory. The set of shader records may represent shader bindings for an object instance under various predefined conditions. One or more of these predefined conditions may be implicit in the way the shader records are arranged in memory (e.g., indexed by ray type, by sub-geometry, etc.). For example, a section selector value (e.g., a section index) may be computed to locate and select a shader record based at least in part on a result of a ray tracing query (e.g., what sub-geometry was hit, what ray type was traced, etc.).

摘要： In one embodiment, a method is for rendering medical volumetric images from received volumetric data, using a cinematic rendering approach, based on a Monte Carlo path tracing algorithm (MCPT). The MCPT algorithm uses at least one microfacet-based bidirectional reflectance distribution function (BRDF) for computing a probability how light is reflected at an implicit surface which is used for shading the implicit surface. In one embodiment, the method includes detecting if a surface scatter event is triggered. If yes, the method includes modifying the computation of a local gradient in the BRDF by perturbing the respective received volumetric data by applying a noise function for simulating a roughness of the implicit surface; and shading the implicit surfaces for rendering the received volumetric data.
