GPU HLSL compute shader warnings int and uint division
I keep having warnings from compute shader compilation in that I'm recommended to use uints instead of ints with dividing.
By default from the data type I assume uints are faster; however various tests online seem to point to the contrary; perhaps…

Using input/output structs in GLSL-Shaders
In HLSL I can write:
struct vertex_in
{
float3 pos : POSITION;
float3 normal : NORMAL;
float2 tex : TEXCOORD;
};
and use this struct as an input of a vertex shader:
vertex_out VS(vertex_in v) { ... }
Is there something similar in…

What is the correct way to structure a Cg program?
This tutorial uses explicit OUT structures, e.g:
struct C3E1v_Output {
float4 position : POSITION;
float4 color : COLOR;
};
C3E1v_Output C3E1v_anyColor(float2 position : POSITION,
uniform float4 constantColor)
{

confused about the shading language to use ( HLSL or GLSL ), because of supporting platforms.
HLSL resources are available in abundance, but I saw through the web that it's specific to DirectX (windows). Would that be a problem if I'm planning to…

GLSL ES Pixel Shader only works if unused texcoords are passed in
I have a vertex shader, shared between several pixel shaders - GLSL ES 2.0 on iOS. The VS outputs transformed position, normal and one set of 2D uv coords. Here is the bare-bones of it:
void main() {
vec4 xlt_outPos;
vec3 xlt_outNormal;
