Material modeling system based on PBR material

Abstract

The invention discloses a material modeling system based on a PBR material, and the system comprises: a material manufacturing module which carries out the visual PBR material parameter adjustment of a material template, so as to manufacture a new PBR material; a real-time rendering and previewing module which is used for performing online real-time rendering and previewing an online rendering effect in real time by applying a new PBR material; a data conversion module which is used for converting PBR material parameters corresponding to a new PBR material rendered by the online real-time rendering engine into offline rendering parameters adopted by the offline rendering engine, and aligning a light field adopted by the online real-time rendering engine with a light field required to be adopted by the offline rendering engine; an off-line rendering and preview module which is used for performing off-line rendering by adopting the off-line rendering parameters and the light field needing to be adopted so as to obtain and preview an off-line rendering effect; and a confirmation module which is used for confirming the designed new PBR material by comparing the online rendering effect and the offline rendering effect to be the same. The material modeling system can improve the material modeling efficiency and ensure the material modeling quality.

Description

technical field [0001] The invention belongs to the field of graphics, and in particular relates to a material modeling system based on PBR material. Background technique [0002] With the popularization of the concept of VR, rendering renderings have become a widely accepted terminal visual display medium, and with the improvement of computer performance, the production cost of renderings has been reduced, rendering technology has been widely used in various industries . Material is an important material part in rendering, and its realism determines the upper limit of rendering effect. [0003] Modelers generally create materials by setting a large number of material parameters, and continuously render to verify the material effect. The material parameters are very rich and complex. Sometimes in order to achieve special materials, it needs to be mixed with multiple materials. Therefore, in the process of material production, the modeler needs to have rich experience and t...

Problems solved by technology

This set of mainstream material modeling process requires talents with high technical foundation and modeling experience to operate, and requires a computer with high configuration to perform repeated renderings to check whether the effect is as expected. This process has caused a lot of problems. The waste of rendering resources and the consumption of human resources, and it is impossible to guarantee that the material effect meets expectations

[0005] When using local material modeling software, you can create extremely personalized and professional materials, but generally speaking, there are the following problems: (1) In the material production process of traditional 3dmax or substance designer and other local material software, a large number of rich and complex The parameters are difficult to understand, and the production of complex materials may require the mixing of multiple material nodes, which leads to a high technical threshold for material production. At the same time, modelers need to collect materials and modify parameters to achieve the purpose of improving efficiency. The standard of material modeling is different, the process is inefficient, and the threshold is high; (2) Modeling through local material software also requires high computer configuration for repeated rendering to verify that the rendering effect conforms to the effect of the physical world. The cost is high, and it is also very time-consuming; (3) local software such as Substance designer is used to produce PBR materials, and the effect is verified through real-time rendering. The experience process is fragmented, and it is difficult to ensure that the real-time material effect recalled is consistent with the final offline rendering, and the effect is found to be inconsistent during application

[0006] The above-mentioned material modeling through local material software, because its parameters are complex and difficult to adjust, the technical and experience threshold is too high, the hardware cost is high, the material adjustment process is inefficient and time-consuming, and the effect of real-time rendering and offline rendering is difficult to unify, which limits rendering commercial use of technology

[0007] For online cloud material modeling software, the modeling process lacks flexibility, is very inefficient, and consumes rendering resources

If the user wants to adjust the material parameters to achieve the desired effect, the inability to preview the effect in real time makes the parameter adjustment process extremely painful. Each preview needs to be rendered offline, which also increases a lot of waiting time and wastes a lot of rendering. server resources
