Disclosed in some examples are methods, systems, devices, and machine-readable media for 3D radar weather data rendering techniques. A computer-implemented method for 3D radar weather data rendering includes retrieving weather data from a weather radar. Gridded data is generated based on the weather data. The gridded data includes a uniform grid of cubes, where each of the cubes is associated with at least one weather parameter value of a plurality of weather parameter values corresponding to the weather data. A triangular mesh for a data grouping within the gridded data is extracted. An object file including vertices and faces associated with the triangular mesh is generated. The object file is communicated to a three-dimensional (3D) visualization system to present a 3D rendering of the object file.

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. The aforementioned rasterizing includes shading a subset of the primitives binned to one of the tiles over multiple passes at multiple shading rates, each of the shading rates is based at least on a frequency at which a color being shaded at each pass changes across the screen space, and the subset of the primitives are cached in an on-chip memory of a processor rendering the image between the passes.

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.

The present invention relates to a glossy part of radiation is estimated coming from a surface illuminated by area light source(s) having source surface(s) (A) bounded by edge curves, by determining integrand function(s) representative of that glossy part. The latter corresponding to an integration of the integrand function along the edge curves. In this respect, the integrand function(s) is/are approximated by means of peak-shape function(s) having a known antiderivative over the edge curves, and the glossy part is computed from analytical expressions associated with integrations of the peak-shape function(s) along the edge curves. Such invention can offer efficient and accurate computation for specular part of reflection as well as glossy transmission, and is notably relevant to real-time rendering.
