Embodiment Construction

[0186] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0187] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various concepts herein, but unless otherwise specified, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another. For example, a first feature point could be termed a second feature point, and, similarly, a second feature point could be termed a first feature point, without departing from the scope of the present application.

[0188] Volumetric cloud: The virtual cloud generated by computer equipment is called volumetric cloud. Volumetric clouds are similar to real-world clouds in that they are translucent, irregular, and have a certain shape and thic...

Abstract

The embodiment of the present application discloses an image rendering method, device, equipment and storage medium, belonging to the technical field of image processing. The method includes: determining a plurality of position points arranged on the same plane; for each position point in the plurality of position points: according to the plurality of first feature points and the first noise values ​​of the plurality of first feature points, Select multiple first feature points on the same straight line as sampling points; modify the first noise value of each sampling point according to the currently set rendering parameters to obtain the second noise value of each sampling point, and the sampling point’s The second noise value indicates the thickness of the volume cloud at the sampling point; according to the second noise value of each sampling point, the pixel value of the position point is obtained; and the volume cloud image is generated according to the pixel values ​​of multiple position points. The first noise value is modified to obtain the second noise value, and the rendered volumetric cloud image changes. When the rendering parameters change dynamically, the second noise value changes dynamically, thereby rendering a dynamically changing volumetric cloud.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image rendering method, device, equipment and storage medium. Background technique [0002] Volume rendering technology (Volume Rendering) is a commonly used volumetric cloud rendering technology. Volumetric clouds can be rendered in the interface by using volume rendering technology, simulating the translucent and irregular performance of real clouds and fog. However, how to make the rendered volumetric clouds more realistic has become an urgent problem to be solved. [0003] Due to the use of the Perlin noise algorithm, the generated Perlin noise value has good randomness and continuity. Therefore, the Perlin noise algorithm is currently used to render volumetric clouds. Such as figure 1 As shown, the Perlin noise algorithm is used to generate texture data, the texture data includes multiple feature points and the Perlin noise values ​​of the multipl...
