Embodiment 1

[0057] see figure 1 , which is a flow chart of Embodiment 1 of the three-dimensional model processing method provided by the present invention.

[0058] The three-dimensional model processing method provided in this embodiment includes:

[0059] S101: Acquire a three-dimensional model and a material of the three-dimensional model;

[0060]It should be noted that the three-dimensional model may be a model file that has already been made, or a model file that is made immediately by the user. The 3D model can be a 3D model generated by Sketchup, 3D Studio Max or other model making software. The model data format can be FBX format, 3DS format, etc., and will not be listed here.

[0061] The material of the 3D model, including: metal, wood and glass, etc. In actual operation, its material can be specified by the user according to the actual modeling needs. For example, when the 3D model is a chair, its material type can be leather, wood, metal, etc. In addition, different reg...

Embodiment 2

[0073] see figure 2 , which is a flow chart of Embodiment 2 of the three-dimensional model processing method provided by the present invention.

[0074] The 3D model processing method provided in this embodiment, the acquisition of the 3D model and the material of the 3D model also includes:

[0075] S201: Setting basic parameters of the model scene;

[0076] The basic parameters include: display scale value and color correction value.

[0077] The purpose of setting the display scale value is to make the scale of the model generated by the three-dimensional model processing method provided by the present invention uniform. It can be understood that the setting of the color correction value, such as the gamma value, is also to make the quality of the generated model uniform.

[0078] S202-S206 in this embodiment are the same as S101-S105 in the first method embodiment, and will not be repeated here.

[0079] In order to make the generated 3D model more realistic and three...

Embodiment 3

[0086] The following takes 3D Studio Max software as an example to introduce the specific process of shadow map and AO effect generation.

[0087] see image 3 , which is a flow chart of Embodiment 3 of the three-dimensional model processing method provided by the present invention. Compared to figure 2 , this embodiment provides a more specific three-dimensional model processing method.

[0088] The generating the shadow map of the 3D model according to the material type specifically includes S301-S303:

[0089] S301: Generate a ground shadow object of the 3D model;

[0090] The ground shadow object is a transparent plane;

[0091] It should be noted that the ground shadow object is a plane generated on the ground below the model, which initially has no attributes. After that, assign the shader ball to the ground shadow object, that is, after setting the material parameters of the ground shadow object, the ground shadow object becomes a plane of transparent material.

Abstract

The embodiment of the present invention discloses a three-dimensional model processing method, including: acquiring the three-dimensional model and the material of the three-dimensional model; setting the material parameters of the three-dimensional model according to the material of the three-dimensional model; and generating A shadow map of the 3D model; generating an ambient light shading effect of the 3D model according to the material parameters; baking the shadow map and the ambient light shading effect to the 3D model to generate a 3D model with light and shadow effects Model. The 3D model processing method provided by the embodiment of the present invention directly generates the shadow map and ambient light occlusion effect of the 3D model according to the material of the 3D model specified by the producer, which saves the time for making the model and reduces the time for the producer to learn modeling. time and cost.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a three-dimensional model processing method and device. Background technique [0002] A three-dimensional model, that is, a 3D model can also be said to be a three-dimensional model built with three-dimensional software, including various objects, characters, vegetation, machinery, etc., such as a 3D model diagram of a chair. [0003] With the development of virtual reality technology, the requirements for modeling technology are getting higher and higher. In the traditional 3D model making process, technicians need to spend a lot of time on the necessary technical processing of the 3D model to make it more realistic and three-dimensional, so as to meet the requirements of virtual reality. However, when 3D models are produced by different producers, the material parameters set are not uniform, and the quality of the generated materials is different, resulting in...
