Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0029] According to a method of OBJ file parsing surface rendering based on Unity3D provided by the present invention, comprising:

[0030] Step M1: Unity3D reads the OBJ file model and records it in the data structure;

[0031] Specifically, the step M1 includes:

[0032] Step M1.1: export the OBJ file model information, the file model information includes: the name of the file model, the color of the file model, the vertices of the file model, such as figure 1 As shown, the normals of the file model...

Abstract

The invention provides an OBJ file analysis surface rendering method and system based on Unity 3D and a medium. The method comprises the steps that M1, the Unity 3D reads an OBJ file model and recordsthe OBJ file model in a data structure; and M2, a corresponding model is generated through the read OBJ file model. An original Unity reading model only supports 65535 vertexes, if the number of thevertexes is too large, incomplete reading can be caused, the algorithm reads data through a model cutting method, and the Unity can read the model with multiple vertexes.

Description

technical field [0001] The present invention relates to the technical field of computer vision and video processing, in particular to a method, system and medium for OBJ file parsing surface rendering based on Unity3D. Background technique [0002] At present, many solutions for reading OBJ files to generate models require professional 3D graphics software, and need to reorganize file data such as vertices by themselves; [0003] Patent document CN105205179A (application number: 201510708568.3) discloses a method and device for converting obj-type 3D type files. The method for converting a 3D type file of the obj type includes: creating a read file object; processing the 3D type file of the obj type in a preset reading manner through the read file object; importing the processed information into Into the standard model object, the standard model object can be directly called by the windows platform. This method of creating and reading a file object and directly reading and...
