If... vec3 myVec3 = vec3(1.0, 0.0, 0.5); // myVec3 = {1.0, 0.0, 0.5} vec3 temp = vec3(myVec3); // temp = myVec3
The OpenGL Superbible 5th Edition was recently released, and it documents OpenGL 3.3.Unfortunately, OS X only supports OpenGL 2.1 and GLSL version 1.20.The very first non-trivial vertex shader they gi
I\'m running some experiments in WebGL, one of them being an XOR effect fragment shader. For some reason all the bitwise operators are reserved in GLSL and cause a compiler error when used. Why a开发者
I need a shader that starts with a given texture, then each frame of animation operates on the previous output of the shader plus other input.
In C, I can debug code like: fprintf(stderr, \"blah: %f\", some_var); in GLSL ... is there anyway for me to just dump out a value in a Vertex or Fragment shader? I don\'t care if it\'s slow; I just
Closed. This question needs debugging details. It is not currently accepting answers. Edit the question to include desired behavior, a specific problem or error, and the shortest code nece
after one day of trying to figure out how to implement a kd-tree in OpenGL/GLSL i am pretty frustrated ...
I have a texture with a 3x9 repeating 开发者_如何学Pythonsection. I don\'t want to store the tesselated 1920x1080 image that I have for the texture, I\'d much rather generate it in code so that it can
I am currently learning GLSL.It would seem that once you learn one of the shader languages, learning one of the others would not be too difficult.Is it something analogous to learning a widget toolset
I\'m using a series of shaders to perform realtime image processing on the iP开发者_如何学编程hone (3GS/4/iPad). The fps isn\'t what I\'d like it to be.
