Virtual reality visualization method and device, computer equipment and storage medium

Abstract

The invention discloses a virtual reality visualization method and device, computer equipment and a storage medium, which are used for realizing dynamic import and rapid visualization of any CAD model of a multi-channel VR system and improving VR visualization iteration efficiency of the CAD model. According to the main technical scheme, the method comprises the steps of obtaining a CAD visual model; importing the CAD visual model into the basic virtual scene, and rendering and displaying the CAD visual model according to the geometric information and the material information of the CAD visual model; determining a display position, determined in the basic virtual scene, of the displayed CAD visual model; sending the CAD visual model, the display position and the basic virtual scene to each rendering node; the rendering nodes are used for loading the CAD visualization model into the basic virtual scene, and rendering the CAD visualization model according to the corresponding projection relation; and after all the rendering nodes finish rendering of the CAD visual model, the rendering nodes display a rendering result according to a unified frame sequence.

Description

technical field [0001] The invention relates to the technical field of virtual reality, and in particular, to a virtual reality visualization method, device, computer equipment and storage medium. Background technique [0002] VR technology refers to simulating the real world through a computer simulation system, and providing users with a multi-information, three-dimensional dynamic and interactive simulation experience through the fusion of multiple information. Different from traditional interaction methods, users can interact with the virtual environment with the help of CAVE system, VR helmet, operating handle and other equipment, combined with three-dimensional image display, which is more realistic and autonomous. [0003] Virtual simulation evaluation refers to the use of VR technology in the product design stage to display the digital prototype of the product in three dimensions in the VR environment. Designers use VR equipment to place themselves in the virtual env...

Problems solved by technology

[0004] In the existing technology, if you need to change the model, you need to go back to the visualization software to change the model, and then perform a series of processes such as material editing, lighting calculation, shadow baking, etc., in order to publish the modified visualization model to the multi-channel VR system. The operation is cumbersome and the time period is long, which is not suitable for the rapid iteration of the virtual simulation of the design scheme
