Problems solved by technology

Normal map technology is a technology that has been maturely used, but since the normal information of the model is reduced after the model is simplified, the normal map cannot show the bump details before the model is simplified, so it is necessary to study a A method capable of transferring model-rich normal maps

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The traditional model automatic point reduction algorithm performs batch simplification of 3D models in the form of plug-ins or commands in the 3D software integrated development environment. After the end of the automatic optimization command, the developer needs to manually correct all the wrong faces in the optimization model one by one. This after-the-fact processing method deviates from the original intention of automatically optimizing the model to improve work timeliness, and a better alternative should be found, so a 3D model optimization method suitable for mobile augmented reality browsers needs to be used.

[0021] Such as figure 1 As shown, the present invention provides a method for optimizing a three-dimensional model for a mobile augmented reality browser. Taking the process of optimizing a cabinet model by using the me...

Abstract

The invention provides a method for optimizing a three-dimensional model for a mobile augmented reality browser. The method can reduce the waiting time of a user during browsing of a VR scene at a cell phone side and improve the user experience. The method comprises the following steps: Step 1, building a low mould model of an object based on Maya, wherein the low mould model is a model expression form for expressing a basic shape configuration of the object; Step 2, eliminating a hidden surface of the low mould model acquired in the first step, wherein the hidden surface refers to a polygon surface plate in a user invisible area; leading the low mould mode into ZBruh to perform a surface fractionizing operation, and adding model details and generating a high mould mode, wherein the high mould model is a model expression form including rich level details; Step 3, leading the high mould model acquired in the second step and the low mould model acquired in the first step into Maya, and baking a normal map for the low mould model under the reference of a texture coordinate map of the high mould model; Step 4, leading the texture coordinate map of the high mould model and the normal map for the low mould model into Photoshop to generate a color map for the low mould model, and finally, endowing the color map to the low mould model.

Description

technical field [0001] The invention belongs to the technical field of mobile augmented reality, and in particular relates to a three-dimensional model optimization method for a mobile augmented reality browser. Background technique [0002] In recent years, with the rapid development of mobile computing technology, the ability of mobile smart terminals to process complex data has generally improved. The rapid development of embedded computing still cannot meet the current demand for real-time computing of huge data. Therefore, when mobile applications call virtual objects in a virtual reality or augmented reality environment, high memory usage, low screen refresh rate, and rendering consumption usually occur. time and many other issues. Since augmented reality browsers generally adopt a client / server distributed architecture, calling the resource set located in the cloud will be limited by the data transmission bandwidth of the mobile cellular network. The browser cannot ...
