WebDec 26, 2013 · I tried to do it by hand but finally i found refract from GLSL, which is documented in GLSL 1.1 like this: //For a given incident vector I, surface normal N and ratio of //indices of refraction, eta, refract … WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
WebConsider the four points, A, B, C and D. Let's crudely reduce the distance function to try and get rid of the min/max functions in order to understand their effect (since that's what's puzzling about this function). The notation below is a little sloppy, I'm using square brackets to denote 2D vectors. WebNov 10, 2009 · liengen November 10, 2009, 6:21am #2. Solved the problem by making my own refract function. Turned out that the refract function implemented worked as it was supposed to. The only problem was that it didnt “blend” the sphere as I wanted it to blend. system closed October 19, 2024, 7:30pm #3. This topic was automatically closed 183 …
WebApr 13, 2010 · Hi, 🙂 I would like to program a shader that does refract the scene on an object that is being displayed. So far that’s what I’ve done : Vertex Shader : varying vec3 Position; varying vec3 Normal; void main() { gl_TexCoord[0] = gl_MultiTexCoord0; gl_Position = ftransform(); gl_FrontColor = gl_Color; Position = vec3(gl_ModelViewProjectionMatrix * … WebJavascript Jest timer Mock不允许我的测试解除阻止,javascript,node.js,jestjs,Javascript,Node.js,Jestjs,我已经阅读了JS运行时、事件循环、堆栈、作业和回调队列，除此之外，对我来说似乎是同一个问题，但我无法理解为什么这个承诺在我的测试中永远不会回来。
