PROBLEM TO BE SOLVED: To provide a shading method in computer graphics capable of representing a dark part by pasting an image with a pattern not by reducing a luminance of a surface to darken the surface when executing representation such that the surface of a three-dimensionally shaped object...

enables platform-independent description and exchange across applications and renderers. First launched at Industrial Light & Magic in 2012, MaterialX provides an open standard to represent the data values and relationships required to describe the look of a computer graphics model. This includes ...
This model balances accuracy and computational efficiency, making it suitable for real-time rendering in older graphics pipelines. Physically-based rending (PBR) Physically-based rendering (PBR) is an advanced approach in computer graphics that aims for photorealistic rendering. It models light ...
This article presents a survey of popular shading models used in 3D computer graphics. Each model is discussed on the basis of an hardware-accelerated implementation that runs on typical consumergrade graphics boards. The discussion is f... K Schwenk 被引量: 9发表: 2009年 Calculation method for...
光照模型包括环境光、漫反射光和镜面反射光,可以根据材质属性和光源属性进行调整,从而实现逼真的光照效果。The purpose of this project is creating a lighting effect by applying the lighting model in the vertex and fragment shaders using OpenGL.
