Processing method and device for judging overlapping between models

Abstract

The invention relates to a processing method and a device for judging overlapping between models. The method comprises the steps of acquiring a first model and a second model in a scene; determining afirst projection after the first model is projected to a two-dimensional plane and a second projection after the second model is projected to the two-dimensional plane; and judging whether the firstmodel and the second model are overlapped according to the overlapping region of the first projection and the second projection. Compared with the prior art that the position is selected by dividing grids, the relative position between the object models obtained after the position is adjusted through the method is more random, and the method is more suitable for some scenes where objects are randomly placed; moreover, the scene does not need to be manually divided into grids in advance, and whether the width and height of the test grid are reasonable is repeatedly verified, so that the manualprocessing amount can be effectively reduced, and the research and development efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a processing method and device for judging overlap between models. Background technique [0002] Computer graphics technology has been widely used in games, film production and other fields that require special effects production. A common graphics rendering process includes: model loading, texture mapping, and rendering display process. In the actual rendering and display process, due to the complexity of the scene and too many target objects, it is often unavoidable that the objects will occlude and overlap each other, which does not meet expectations. [0003] For example, in some pictures in which there are multiple objects and each object has a front-back position relationship, the front object will cause serious occlusion to the rear object. Similar situations often occur in scenes where multiple minions block each other in the game. [0004] The curre...

Problems solved by technology

However, there are problems with this method. Dividing into multiple grids can easily lead to insufficient random positions and appear too neat. Sometimes it is not suitable for some scenes that need to be placed randomly

For each scene, the width and height of each grid needs to be preset in advance, which makes this process time-consuming and laborious. It usually requires repeated tests to find a suitable width and height to avoid occlusion
