Embodiment
[0080] Such as image 3 As shown, first, the program starts to run;
[0081] Determine the level of importance of different parts of the model, and the process of initial compression of the model according to the corresponding level of each part is as follows:
[0082] Eliminate multiple sub-materials, assign new materials to components with lost materials, unify model materials into standard materials, avoid incompatibility between different engine versions due to format conversion, and uniformly name the mesh models and materials in the file, so that each The name of each grid and material is unique. The model is displayed on the interface of the predetermined software, and the display angle of the model is the predetermined display angle. The predetermined display angle is 45 degrees. The structure that cannot be observed at the 45-degree view is defaulted to Don’t pay attention to the redundant structure, give it clear, and default the structure that can’t recognize the c...

The invention provides a model data processing method and device and a computer readable storage medium. The method comprises the steps that the levels of the importance degrees of different parts of a model are determined, and the higher the levels are, the more important the corresponding parts are; initial compression is conducted on the model according to the corresponding grades of all the parts, at least the model subjected to initial compression forms an initial compression file, the compression ratios of any two parts with different grades are different, and the compression ratio of the part with the high grade is large. In the method, different parts in a model are determined as levels of different importance degrees, the level corresponding to each part is compressed, the part with the higher level is an important part, and the important part is compressed by adopting a compression ratio greater than that of other parts with lower levels, or the important part is not compressed, so that the compression efficiency of the model is improved. Therefore, it can be ensured that part of important structures are not distorted when a large model is compressed, and the problem of serious distortion caused by a compression technology in the prior art is solved.
Description
technical field [0001] The present application relates to the field of model data processing, and in particular, relates to a model data processing method, device, computer-readable storage medium, and processor. Background technique [0002] With the maturity of construction robots, related 3D technologies such as lightweight BIM engines, digital twins, and digital simulations have also developed rapidly. The intermediate formats of mainstream 3D models include obj, fbx and the outdated 3ds format. In the robot offline programming system and WEB side, the loading and rendering speed of the model needs to be within an acceptable range. For large models, the loading and rendering performance is extremely poor, and even the platform crashes due to the influence of computing power and memory limitations, which is difficult to meet the simulation requirements. Waiting for demand. And there is currently no good compression scheme that can solve this problem well. [0003] Alth...
