Embodiment Construction

[0036] In actual image processing, 3D models need to be constructed and rendered. However, when using a conventional 3D engine for rendering, it results in a huge amount of calculation, high difficulty in data processing, and high hardware configuration requirements.

[0037] The overall method of the present invention is: for the 3D model, the bounding box of the model can be obtained (a set of coordinate points of a three-dimensional space cuboid, which surrounds the smallest cuboid of the 3D model), and according to the actual accuracy requirements, the bounding box can be split into several For small cuboids, use the 3D engine to perform collision detection on the original 3D model and several small cuboids, and mark each small cuboid in space, then the surface of the outer contour of the 3D model will collide with some / some cuboids, so , can use the existing 3D collision detection technology to distinguish the collision, so select those cuboids that have collided, you can ...

Abstract

The invention relates to a copying rendering method of a 3D model, and belongs to the technical field of image processing. For a 3D model, a bounding box of the model can be obtained, the bounding boxis divided into a plurality of small cuboids according to the actual precision requirement, collision detection is conducted on the original 3D model and the small cuboids through a 3D engine, spacemarking is conducted on each small cuboid, and the 3D model is redrawn. The method has the advantages that the spatial structure data of the 3D model is simplified; The rendering of the 3D model is free from a 3D engine, so that the 3D model is lighter, the mobile display requirement of the 3D model is promoted, and the threshold from model design to model display is reduced; The spatial calculation of the 3D graph is simpler, and the collision problem of the model and the position problem of the model can be solved very conveniently.

Description

technical field [0001] The invention relates to a copying and rendering method of a 3D model, which belongs to the technical field of image processing. Background technique [0002] A 3D model can also be said to be a three-dimensional model built with 3D software, including various buildings, characters, vegetation, machinery, etc., such as a 3D model diagram of a building. [0003] Nowadays, there are also various forms of online advertisements, such as text advertisements, picture advertisements, video advertisements, etc., the purpose of which is to provide users with better browsing methods, display effects, attract users, increase user attention, interaction, and participation, and ultimately achieve Conversion rates. It is an inevitable trend that the two-dimensional display method will be replaced by the three-dimensional stereoscopic method in the near future, but this must be based on a 3D modeling technology that is easy to operate, low in cost, and has a stron...
