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 invention discloses an image rendering method, device and equipment and a storage medium, and belongs to the technical field of image processing. The method comprises the following steps: 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 thefirst noise values of the plurality of first feature points, selecting the plurality of first feature points located on the same straight line as sampling points; modifying the first noise value of each sampling point according to a currently set rendering parameter to obtain a second noise value of each sampling point, the second noise value of each sampling point indicating the thickness of thevolume cloud at the sampling point; obtaining a pixel value of the position point according to the second noise value of each sampling point; and generating a volume cloud image according to the pixel values of the plurality of position points; and modifying the first noise value to obtain a second noise value, and changing the rendered volume cloud image. And when the rendering parameter is dynamically changed, the second noise value is dynamically changed, so that the dynamically changed volume cloud is rendered.

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...
