Abstract: The present disclosure relates to a texture mapping method and apparatus, a device, and a storage medium. The texture mapping method includes: obtaining three-dimensional coordinates and a normal direction of a fragment of a three-dimensional grid; determining sampling coordinates based on the three-dimensional coordinates and the normal direction of the fragment; performing a sampling on a preset texture image based on the sampling coordinates; and mapping an image obtained by the sampling to the fragment based on an association relationship between the sampling coordinates and the fragment.

Abstract: This disclosure discloses an image rendering method and apparatus. The image rendering method includes: obtaining a first depth and a second depth corresponding to each pixel point of pixel points in an image to be rendered, wherein the first depth corresponding to the pixel point is a depth of a real scene corresponding to the pixel point in a Normalized Device Coordinate system, and the second depth corresponding to the pixel point is a depth of a virtual scene corresponding to the pixel point in the Normalized Device Coordinate system; obtaining a depth difference corresponding to the each pixel point based on the first depth and the second depth corresponding to the each pixel point, wherein the depth difference corresponding to the pixel point is a difference between a depth of a real scene corresponding to the pixel point and a depth of a virtual scene corresponding to the pixel point in a camera coordinate system; determining an opacity corresponding to the each pixel point according to the depth difference corresponding to the each pixel point, wherein the depth difference corresponding to the each pixel point is positively correlated with the opacity corresponding to the each pixel point; and rendering a layer corresponding to the virtual scene over a layer corresponding to the real scene to generate the image to be rendered based on the opacity corresponding to the each pixel point.

Abstract: A video processing method and apparatus, a device, and a storage medium are provided. The method includes: acquiring three-dimensional reconstruction data of a video image and a first texture image corresponding to a current moment; determining target brightness of a target pixel position on the first texture image corresponding to the current moment according to a pre-obtained mapping relationship between pixel positions and initial brightness and brightness change rates; adjusting brightness of the target pixel position on the first texture image to the target brightness so as to obtain a second texture image; and mapping the second texture image onto the video image based on the three-dimensional reconstruction data so as to obtain a target video image.
