In a vertex shader, I calculate a vector using only uniforms. Therefore, the outcome of this calculation is the same for all instantiations of the vertex shader. Should I just do this calculation on t
Is there a maximum number of assembly开发者_StackOverflow中文版 language instructions to be loaded into the fragment program unit?
I would like to render the 3D volume data: Density(can be mapped to Alpha channel), Temperature(can be mapped to RGB).
I\'m doing ray casting in the fragment shader. I can think of a couple ways to d开发者_Go百科raw a fullscreen quad for this purpose. Either draw a quad in clip space with the projection matrix set to
I\'m trying to learn to play with OpenGL GLSL shaders.I\'ve written a very simple program to simply create a shader and compile it.However, whenever I get to the compile step, I get the error:
I am trying to use a trivial geometry shader but when run in Shader Builder on a laptop with a GMA X3100 it falls back and uses the software render. According this document the GMA X3100 does support
Is it possible to set the color of a single vertex using a GLSL vertex 开发者_Python百科shader program, in the same way that gl_Position changes the position of a vertex ?For versions of GLSL prior ve
I need to debug a GLSL program but I don\'t know how to output intermediate result. Is it possible to make some debug traces (like with printf) 开发者_运维技巧with GLSL ?You can\'t easily communicate
I am trying to get update the eye position in my shader from my appliaction but I keep getting error 1281 when I attempt this. I have no problems after the initialization just when i subsequently try
