  • Patent number: 12039662
    Abstract: A method and apparatus for recognizing a pixel point, an illumination rendering method and apparatus, an electronic device, and a storage medium, which is used to effectively detect a pixel point located in a shadow region, to improve the quality of lightmap rendering. The method includes: obtaining a lightmap of a target object in a target scene; determining, according to a distance between each adjacent pixel point of a pixel point in the lightmap and the pixel point, a coverage radius corresponding to the pixel point; and determining, by using the pixel point as a starting point, that when a ray emitted along at least one tangential direction of the pixel point intersects an unlighted surface of an object in the target scene and a length of the ray is the same as the coverage radius, the pixel point is located in the shadow region.

  • Publication number: 20230033319
    Abstract: A method for processing a shadow texture can compute data concurrently to improve computation density, reduce data transmission batches, and improve shadow texture processing efficiency. Model data and light source information of at least one object in a virtual scene is acquired. A shadow with a first resolution corresponding to each object is acquired. A second resolution is determined based on the model data of each object. A shadow edge formed by each object under the influence of the light source information is determined in parallel by utilizing rasterized pixels of the model data. The distance from the rasterized pixels to the shadow edge corresponding to each object is computed, and the corresponding distance data is stored.

  • Publication number: 20220392144
    Abstract: This application discloses an image rendering method and apparatus, an electronic device, and a storage medium, and belongs to the field of image processing technologies. The method includes: acquiring a lightmap of a target three-dimensional model in response to a light rendering instruction; acquiring a seam edge of the target three-dimensional model; determining, in the lightmap, a target pixel corresponding to the seam edge; and updating an initial pixel value of the target pixel in the lightmap to obtain a repaired lightmap. In this application, the seam edge of the target three-dimensional model is automatically identified, and the pixel value of the target pixel is automatically updated, so that automatic recognition and automatic repair of a seam problem can be completed by one click, thereby avoiding a waste of labor resources for troubleshooting and repairing the seam problem, reducing image rendering time, and improving image rendering efficiency.

  • Publication number: 20220207821
    Abstract: An image rendering method and a related apparatus, terminal and storage medium that: obtains a low-resolution first shadow map and a high-resolution second shadow map of a target virtual object, determines a first texel range of each texel and a central point in the first shadow map, performs scaling processing, based on the central point, on the first texel range by using a scaling coefficient to obtain a second texel range, and performs shadow rendering on the target virtual object according to the second texel range. A shadow map-based image rendering process is implemented, and since a calculation amount of determining a map position according to a low-resolution map is relatively small, image rendering efficiency is improved. Additionally, rendering of a high-resolution shadow map is completed, generation of edge aliasing is avoided, and an image rendering effect is improved.
