Abstract

The invention discloses a neural network-based calculation method for real-time physical engine enhancement, which includes the steps of: building a multi-layer and multi-face pre-collision shell: dynamically constructing a multi-layer and multi-face pre-collision according to the key concave-convex vertices of objects to be detected for collision Shell; relationship matrix acquisition step: obtain the initial collision detection correspondence relationship matrix based on the multi-layer and multi-face pre-collision shell; screening and judgment step: set the collision detection condition, input the relevant parameters of the collision detection condition into the neural network for parameter screening, screening Finally, judge whether the collision condition meets the safety condition; when the collision condition meets the safety condition, the collision detection correspondence matrix is ​​not updated; Collision shell. In addition, the present invention also discloses a computer-readable storage medium storing a computer program and a computing system enhanced by a neural network-based real-time physics engine.

Description

technical field [0001] The present invention relates to the field of physics, in particular to a neural network-based system, medium and method. In particular, it relates to a system, medium and method for enhancing a neural network-based real-time physics engine Background technique [0002] Scenes such as engineering mechanics, driving simulation, material simulation, and clothing digital try-on need to follow Newton's laws of mechanics and laws of gravity, and use physics engines to achieve results close to the real natural world. With the help of many physical models in the physics engine, especially the real-time collision detection in many physical models is one of the most common and consumes the most calculation time. The most closely related is the area and number of surface triangles of multiple objects to be collided. [0003] The current collision usually adopts the method of point-to-plane distance calculation, but when the area becomes larger or the fixed poin...
