How do I get textures to work in OpenGL?

Question

I\'m using the tutorials on http://arcsynthesis.org/gltut/ to learn OpenGL, it\'s required, I have to use it. Mostly I want to apply the textures from Tutorial 15 onto objec

Ok guys, I've worked on this whole thing, and did manage to somehow get it running. First off I had to add samplers:

GLuint g_samplers;

//Add Later
void CreateSamplers()
{
glGenSamplers(1, &g_samplers);

    glSamplerParameteri(g_samplers, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glSamplerParameteri(g_samplers, GL_TEXTURE_WRAP_T, GL_REPEAT);

//Linear mipmap Nearest
glSamplerParameteri(g_samplers, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glSamplerParameteri(g_samplers, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
}

I also added this to the file thing:

glimg::OpenGLPixelTransferParams xfer = glimg::GetUploadFormatType(pImageSet->GetFormat(), 0);

glimg::SingleImage image = pImageSet->GetImage(0, 0, 0);
glimg::Dimensions dims = image.GetDimensions();
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, dims.width, dims.height, 0, 
  xfer.format, xfer.type, image.GetImageData());

The xfer variable does get the format and type adjusted to the dds. Also the render code got turned into this:

//Added necessary 
glActiveTexture(GL_TEXTURE0 + g_colorTexUnit);
glBindTexture(GL_TEXTURE_2D,g_checkerTexture);
glBindSampler(g_colorTexUnit, g_samplers);
g_pLeftMesh->Render();
glBindSampler(g_colorTexUnit, 0);
glBindTexture(GL_TEXTURE_2D, 0);

And of course at the end of init() I needed to add the CreateSamplers thing:

//Added this later
LoadCheckerTexture();
CreateSamplers();

I'm sorry for all the trouble with all this, but guess OpenGL really is just this confusing and it was just dumb luck that I got it right. Just posting this so that people know
