I\'ve been wondering whether it is possible to have an array of sampler2D in a GLSL 1.5 vertex shader.
I was wondering if there is support in the newer shader models to read-back a pixel value from the target framebuffer. I assume that this is alrdy done in later (non-programmable) stages in the drawin
I\'m attempting to plot an iterative function in OpenGL ES. An array of ints is being updated with how often a given pixel is hit by the iterative function. I\'d like to pass this density array to a f
I am trying to get Ardor3D\'s terrain system to work on SM3.0 hardware. The current GLSL fragment shader uses a uniform vec2 array to pass an array of xy coordinates into the fragment shader.
I\'m trying to render a simple textured quad in OpenGL ES 2.0 on an iPhone. The geometry is fine and I get the expected quad if I use a solid color in my shader:
I\'m looking for a way to draw something similar to these \"knobs\" with an GLSL shader I only want to draw the coloured circles, and my application is not for a knob rather开发者_高级运维 a funky
I am trying to create an OpenGL fragment shader that converts a normal image to an image that contains fish eye effect. This is what i mean by fish eye affect (http://www.marcofolio.net/photoshop/crea

As we all get to know eventually, the specification is one thing and the implementation is another. Most of bugs we cause ourselves, but sometimes that\'s not the case.
I have a rather simple fragment shader with a branch and I\'m a bit unsure how it is handled by the GLSL compiler and how it would affect performance.
