OpenGL CG Technique doesnt validate on linux

Recommended Posts

Nanook    537
I have a really simple cgfx file.. On windows it works fine with both OpenGL and DirectX, but on linux it doesn't validate.

cgGetErrorString says: "Invalid technique handle."

If I run the cgfx file through cgc specifying fp40 and vp40 which is the profiles of the basic_textured_ogl_40 technique I get 0 errors..

This is the code that loads the technique..

[CODE]
m_cgEffect = cgCreateEffect(cgContext, data, NULL);
m_cgTechnique = cgGetFirstTechnique(m_cgEffect);
while (m_cgEffect && cgValidateTechnique(m_cgTechnique) == CG_FALSE)
{
std::cout << "Technique " << cgGetTechniqueName(m_cgTechnique) << " did not validate" << std::endl;
m_cgTechnique = cgGetNextTechnique(m_cgTechnique);
}
if (!m_cgTechnique)
{
std::clog << "Your GPU does not support any of the techniques available" << std::endl;
exit(1);
}
[/CODE]

The cgfx file:

[CODE]
void mainVS(float4 position : ATTR0,
float3 normal : ATTR2,
float2 texCoord : ATTR8,
out float4 oPosition : POSITION,
out float2 oTexCoord : TEXCOORD0,
uniform float4x4 viewProjection,
uniform float4x4 world)
{
oPosition = mul(world, position);
oPosition = mul(viewProjection, oPosition);
oTexCoord = texCoord;
}
void mainFS(float2 texCoord : TEXCOORD0,
out float4 color : COLOR,
uniform sampler2D texSampler0)
{
color = tex2D(texSampler0, texCoord);
}

float4x4 world : World;
float4x4 viewProjection : ViewProjection;

sampler2D texSampler0 = sampler_state {
generateMipMap = true;
MinFilter = LinearMipMapLinear;
MagFilter = Linear;
WrapS = Repeat;
WrapT = Repeat;
};
technique basic_textured_dx_40
{
pass
{
FragmentProgram = compile ps_4_0 mainFS(texSampler0);
VertexProgram = compile vs_4_0 mainVS(viewProjection, world);
DepthTestEnable = true;
DepthMask = true;
}
}
technique basic_textured_ogl_40
{
pass
{
FragmentProgram = compile fp40 mainFS(texSampler0);
VertexProgram = compile vp40 mainVS(viewProjection, world);
DepthTestEnable = true;
DepthMask = true;
}
}
[/CODE]

Found out I had to add in another technique as I got an ATI card on this linux computer and apparently cg doesnt support the other profiles on ATI cards?

[CODE]
technique basic_textured_ogl_arb1
{
pass
{
FragmentProgram = compile arbfp1 mainFS(texSampler0);
VertexProgram = compile arbvp1 mainVS(viewProjection, world);
DepthTestEnable = true;
DepthMask = true;
//CullFaceEnable = false;
//BlendEnable = false;
//DepthFunc = LEqual;
}
}
[/CODE]

      Hello. I'm Programmer who is in search of 2D game project who preferably uses OpenGL and C++. You can see my projects in GitHub. Project genre doesn't matter (except MMO's :D).

      Hello, My name is Matt. I am a programmer. I mostly use Java, but can use C++ and various other languages. I'm looking for someone to partner up with for random projects, preferably using OpenGL, though I'd be open to just about anything. If you're interested you can contact me on Skype or on here, thank you!

      Hello, my name is Mark. I'm hobby programmer. 
      So recently,I thought that it's good idea to find people to create a full 3D engine. I'm looking for people experienced in scripting 3D shaders and implementing physics into engine(game)(we are going to use the React physics engine). 
      And,ye,no money =D I'm just looking for hobbyists that will be proud of their work. If engine(or game) will have financial succes,well,then maybe =D
      Sorry for late replies.
      I mostly give more information when people PM me,but this post is REALLY short,even for me =D
      So here's few more points:
      Engine will use openGL and SDL for graphics. It will use React3D physics library for physics simulation. Engine(most probably,atleast for the first part) won't have graphical fron-end,it will be a framework . I think final engine should be enough to set up an FPS in a couple of minutes. A bit about my self:
      I've been programming for 7 years total. I learned very slowly it as "secondary interesting thing" for like 3 years, but then began to script more seriously.  My primary language is C++,which we are going to use for the engine. Yes,I did 3D graphics with physics simulation before. No, my portfolio isn't very impressive. I'm working on that No,I wasn't employed officially. If anybody need to know more PM me.

      I am developing my engine using the OpenGL 3.3 compatibility profile. It runs as expected on my NVIDIA card and on my Intel Card however when I tried it on an AMD setup it ran 3 times worse than on the other setups. Could this be a AMD driver thing or is this probably a problem with my OGL code? Could a different code standard create such bad performance?

      I'm trying to get some legacy OpenGL code to run with a shader pipeline,
      The legacy code uses glVertexPointer(), glColorPointer(), glNormalPointer() and glTexCoordPointer() to supply the vertex information.
      I know that it should be using setVertexAttribPointer() etc to clearly define the layout but that is not an option right now since the legacy code can't be modified to that extent.
      I've got a version 330 vertex shader to somewhat work:
      #version 330 uniform mat4 osg_ModelViewProjectionMatrix; uniform mat4 osg_ModelViewMatrix; layout(location = 0) in vec4 Vertex; layout(location = 2) in vec4 Normal; // Velocity layout(location = 3) in vec3 TexCoord; // TODO: is this the right layout location? out VertexData { vec4 color; vec3 velocity; float size; } VertexOut; void main(void) { vec4 p0 = Vertex; vec4 p1 = Vertex + vec4(Normal.x, Normal.y, Normal.z, 0.0f); vec3 velocity = (osg_ModelViewProjectionMatrix * p1 - osg_ModelViewProjectionMatrix * p0).xyz; VertexOut.velocity = velocity; VertexOut.size = TexCoord.y; gl_Position = osg_ModelViewMatrix * Vertex; } What works is the Vertex and Normal information that the legacy C++ OpenGL code seem to provide in layout location 0 and 2. This is fine.
      What I'm not getting to work is the TexCoord information that is supplied by a glTexCoordPointer() call in C++.
      Question:
      What layout location is the old standard pipeline using for glTexCoordPointer()? Or is this undefined?
       
      Side note: I'm trying to get an OpenSceneGraph 3.4.0 particle system to use custom vertex, geometry and fragment shaders for rendering the particles.
