Problems solved by technology

[0003] In the prior art, the method of obtaining dynamic wallpaper by 3D rendering is very suitable for general situations, but it is not so easy to realize in the face of some special visual requirements (such as high-tech holographic projection effects, scenes of water splashes, etc.), for example, For the scene where the vertices are distorted by a large amount, because the points cannot form a normal triangle, there will be broken surfaces

Embodiment Construction

[0052] In order to facilitate a better understanding of this application, several concepts involved in this application are introduced first.

[0053] 1. Point Cloud

[0054] Point cloud is a collection of massive points on the target surface obtained by measuring instruments.

[0055] The point cloud obtained according to the principle of laser measurement (such as measurement by laser scanner), including three-dimensional coordinates (XYZ) and laser reflection intensity (Intensity).

[0056] The point cloud obtained according to the principle of photogrammetry (such as by camera measurement), including three-dimensional coordinates (XYZ) and color information (RGB).

[0057] The point cloud is obtained by combining the principles of laser measurement and photogrammetry, including three-dimensional coordinates (XYZ), laser reflection intensity (Intensity) and color information (RGB).

[0058] After obtaining the spatial coordinates of each sampling point on the surface of t...

Abstract

An embodiment of the invention provides a dynamic wallpaper generating method, device and apparatus and a medium, wherein the method comprises: acquiring vertex data that are extracted from a 3D modelor point cloud data; adding vertex color to the vertex data; generating a dynamic wallpaper according to the vertex data which vertex color is added to. By using the dynamic wallpaper generating method, device and apparatus and the medium, point rendering is performed to generate a dynamic wallpaper; surface fracture due to failure of points to form a normal triangle is avoided.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a dynamic wallpaper generation method, device, equipment and medium. Background technique [0002] In the prior art, most of the dynamic wallpapers of smart phones use 3D models to match textures, and then render them with triangular faces according to the vertices of the models. [0003] In the prior art, the method of obtaining dynamic wallpaper by 3D rendering is very suitable for general situations, but it is not so easy to realize in the face of some special visual requirements (such as high-tech holographic projection effects, scenes of water splashes, etc.), for example, For the scene where the vertices are distorted by a large amount, because the points cannot form a normal triangle, there will be broken surfaces. Therefore, how to design and generate dynamic wallpapers to meet some special visual needs (such as high-tech holographic projection effects, water...
