I read lots of information about getting depth with fragment shader. such as http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=234519
I tried to use the transform feedback function, and I made 2 vertex shaders which only affects vertex position.
I am a Computer Science Student and I am currently doing a 2d Game for my Coursework. I know that it\'s kind of unnecessary, but I tried to implement the FXAA algorithm for the AA of the game. The sha
I\'m new to OpenGL and shaders. I have a project that involves using shaders to display cubes. So basically I\'m supposed to display eight cubes using a perspective projection at (+-10,+-10,+-10) fro
I\'m new to WebGL and I\'m facing some problems of the shaders. I wanna do multiple light sources in the scene. I searched online and knew that in WebGL, you can\'t pass an arrayinto the fragment shad
Let\'s say my texture is 256x256 pixel. It contains 16 sub-textures of 64x64 pixel. The sub-textures are to be rendered to quads. To increase performance I want to pass discrete values to the shader w
I encountered what seemed to me as strange behavior using glUniformMatrix4x3fv. Specifically when I give TRUE as for the transpose flag entire rows of my matrices are missing in my shader variable (an
The problem is that I pass two textures in shader, but the picture on 3-d model is the same for both sampler2D variables开发者_运维技巧 (It is with image \"normal.jpg\", the first one.). I\'ll be very
I am writing my first program using OpenGL, and I have gotten to the point where I am trying to get it to compile my extremely simple shader program. I always get the error that it failed to compile t
I have written a level renderer in OpenGL following many online tutorials. I actually render with vertex arrays and the开发者_StackOverflow中文版 range draw command. Now because I want to have the lev
