Abstract

The embodiment of the invention discloses an information processing method and device and a computer readable storage medium, and the method comprises the steps: obtaining a quadrangle in an illumination image, and screening a target quadrangle through rectangular matching; performing parallel clustering based on the target quadrangle to obtain line segment clusters and corresponding clustering lengths; and uniformly adjusting vertex coordinates in illumination mapping of the illumination graph according to the rectangular constraint of the target quadrangle, the clustering length constraint and the angle constraint of the non-target quadrangle. Therefore, a target quadrangle similar to the rectangle in the illumination image is determined; line segment clustering is carried out on the target quadrangle; all line segment clusters and the average length corresponding to each line segment cluster are obtained; and finally, in combination with the rectangular constraint of the target quadrangle, the clustering length constraint of each line segment cluster and the angle constraint that the shape of the non-target quadrangle is not changed, the oblique line in the illumination image isautomatically adjusted into a flat straight line segment or a quadrangle right angle for optimization, and the information processing efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to an information processing method, device, and computer-readable storage medium. Background technique [0002] The light map is a data structure that stores the light information of the pre-calculated object surface in the virtual scene for subsequent rendering calculations. It is usually represented by a two-dimensional image and is widely used in static objects for real-time three-dimensional rendering. It is a computationally cheap global illumination method. [0003] In the existing technology, light maps are often used in game development. In actual application scenarios, in order to reduce the size of the game, developers use low-resolution light map textures as much as possible. Because low-resolution light map textures The accuracy of the lighting information carried by the map is limited, and the lighting will jump between pixels. Especially ...
