System: Windows 7 64 bit Visual Studio 2013 (Visual Studio 2012 is still installed) Perl is installed (ActivePerl-5.18.2.1801-MSWin32-x64-297964.msi) Python is installed (python-2.7.6.amd64.msi) Direct X 10 SDK is installed (DXSDK_Jun10.exe I had to use this workaround ) Downloaded Qt 5.2.1 Downloaded Qt 5.3.0 alpha What I did multiple time: Extract the sources in a temp folder (C:\QtSrc) Delete qtwebkit

But when I use shaders like this: Vertex Shader: attribute vec4 aVertex; attribute vec4 aColor; varying vec4 vColor; void main(void) { gl_Position = gl_ModelViewMatrix * gl_ProjectionMatrix * aVertex; vColor = aColor; } where the attributes aVertex and aColor comes from a vertex buffer, passed through a call of glVertexAttribPointer .

I know that iGlobalTime is the time elapsed since the Shader started, and I think the iChannel stuff is for pulling rgb out of textures, but would appreciate info on how to set these. edit: have been going through all the shaders that come with three.js examples and think that the answers are all in there somewhere - just have to find the equivalent to e.g. iChannel1 = a texture input etc. 回答1: I am not sure if you have answered your

Here's the main code: GLuint VertexArrayID; glGenVertexArrays(1, &VertexArrayID); glBindVertexArray(VertexArrayID); GLuint VertexArrayID2; glGenVertexArrays(1, &VertexArrayID2); glBindVertexArray(VertexArrayID2); GLuint programID = LoadShaders( "SimpleVertexShader.vertexshader", "SimpleFragmentShader.fragmentshader" ); GLuint MatrixID = glGetUniformLocation(programID, "MVP"); GLuint MatrixID2 = glGetUniformLocation(programID,

This question relates to using shaders (probably in the Unity3D milieu, but Metal or OpenGL is fine), to achieve rounded edges on a mesh-minimal cube. I wish to use only 12-triangle minimalist mesh cubes, and then via the shader, Achieve the edges (/corners) of each block being slightly bevelled. In fact, can this be done with a shader ? Thanks, shader gurus! I recently finished creating such shader. The only way it can work is by providing 4 normal vectors instead of one for each vertex (smooth, sharp and one for each edge of the triangle for the given vertex). You will also need one float3

This is my first time debugging glsl Hello I am VERY new to opengl. I am working on modifying another shader I found online. The version I found online works just great, however somewhere along in my code I made a mistake while editing. The problem is I have combed through it and can not see it, I was hoping for some fresh eyes. To be clear it is not that what is being drawn is incorrect, it flat out wont compile #version 330 core struct Material {

I keep hitting this problem when building game engines where my classes want to look like this: interface Entity { draw(); } class World { draw() { for (e in entities) e.draw(); } } That's just pseudo-code to show roughly how the drawing happens. Each entity subclass implements its own drawing. The world loops through all the entities in no particular order and tells them to draw themselves one by one. But with shader based graphics, this tends to be horribly inefficient or even infeasible. Each entity type is probably going to have its own shader program. To minimize program changes, all
