Refract glsl
WebFor reflect function, the formula is given in th HLSL documentation, but for refract function it is not. It took me some time to find the implementation, but finally I've found it in the GLSL … Web最佳答案. refract () 的第三个参数被记录为“折射率 eta 的比率”。. 所以你的建议对我来说很有意义。. 它的比率是 eta 从 Material A 到 Material B，比率将为 1.0 / eta 从 Material B 到 …

WebRay Marching. Screen space reflection uses a technique known as ray marching to determine the reflection for each fragment. Ray marching is the process of iteratively extending or contracting the length or magnitude of some vector in order to probe or sample some space for information. The ray in screen space reflection is the position vector ...
