Embodiment 1

[0052] like figure 1 As shown, the method includes the following steps:

[0053] S1. Export the required model files and shader files as the basic data source for rendering objects and material mapping objects. In a preferred embodiment of the present invention, the model file and the material ball file are exported through the three-dimensional software 3Dmax. The steps to create a shader file are: open the [Material Editor] window, select the first shader, prepare a "mahogany floor" material, then click the [Get Material] button, and in the pop-up [Material / Map Browser] dialogue box, select [Mtl Library] on the left side of the window, and click the [Save As] button. If there are materials in the [Material / Map Browser] dialog box, click the [Clear Material Library] button to delete all current materials. Select a path in the pop-up [SaveMaterialLibrary] dialog box, enter "material file library" in the [File Name] text box, and click the [Save] button.

[0054] After saving...

Embodiment 2

[0093] In Embodiment 2 of the present invention, the place different from the above-mentioned Embodiment 1 is that the judgment condition (2) for judging whether the current pixel point I (x, y) on the image is a noise pixel can also be: D

[0094] To sum up, the method of the present invention can replace any material with any part, rendering more flexible, and the unity of design style is easier to control. The material replacement process of the specified part is to obtain the corresponding texture name through the currently selected Surface, and find out all the Surfaces with this texture name through the established correspondence between the texture name of the diffuse material and the Surface, and map them on...

Abstract

The invention discloses a rendering and drawing method based on a three-dimensional model for replacing the material of a specified part, and relates to the field of computer graphics and image rendering. The method includes the steps of: exporting the required model file and shader file, uploading the model file and shader file to the rendering server through the background server, the client pulls the corresponding model file from the server, and realizes changing the material of the specified part, and the background server receives To the rendering data sent by the client, put the rendering task into the rendering queue. When the rendering server starts, it automatically reads all the shader files into the memory, and then reads the tasks in the rendering queue in turn. The rendering server pulls the rendering data from the rendering queue. The task obtains the data, and replaces the model material, starts rendering through Vray, and when the rendering is completed, the rendering server uploads the image to the background server for storage. The method of the present invention can replace any part with any material, and the rendering is more flexible, and the uniformity of the design style is easier to control.

Description

technical field [0001] The invention relates to the field of computer graphic image rendering, in particular to a rendering method for replacing the material of a specified part based on a three-dimensional model. Background technique [0002] With the widespread use of 3D cloud design in the home improvement industry, while helping many designers to quickly and effectively complete their renderings, the existing 3D models cannot replace the specified style of material. The existing model color change function is to replace the entire model with another model with a different color, and the options are limited. The realization principle of the existing model color changing function is to make multiple copies of the model, and each copy uses a different material. The user can only choose within a limited range, and cannot partially replace the material according to the part of the model. Contents of the invention [0003] In order to solve the above-mentioned technical pro...
