Hardware color correction update

I was somewhat devastated by the inability to re-write the 3D texture on the fly -- calling glTexImage3D again to replace the texture, in fact, caused a core dump. I can't believe that this is the spec, but I could be mistaken. In any case -- the solution is to call glTexSubImage3D to reload the texture data every frame. This seems to work perflectly.

Also, I should note for other people attempting to do that that in OpenGL if you want to use the vertex shaders, you can't create polygons the old IrisGL way -- you cannot use the glBegin(GL_POLYGON); glVertex3f(); glTexCoord2f(); ... glEnd(); sequence that all us old guys are familiar with. You have to use the glDrawArrays(GL_POLYGON, first, count); call. This means, as well, that you have to load up the arrays in a way that your vertex shader can get to them. These are done with the terribly intuitive1 calls (for a vertex position array called 'p' and texture coordinate array called 'uv')

cgGLSetParameterPointer(cgGetNamedParameter(vertexProgram, "Pobject"), 3, GL_FLOAT, 0, p);
cgGLSetParameterPointer(cgGetNamedParameter(vertexProgram, "TexUV"), 2, GL_FLOAT, 0, uv);

cgGLEnableClientState(cgGetNamedParameter(vertexProgram, "Pobject"));
cgGLEnableClientState(cgGetNamedParameter(vertexProgram, "TexUV"));


In any case, this ability to reload color correction tables is the second-to-last roadblock to releasing this image viewer. The last one is how to turn off the shaders to draw my annotations. This can't be too hard.

Sometimes protein just doesn't cut it and you Pure Keto Cleanse want something sweet. Choosing a low sugar fruit like berries or Granny Smith apples is a great choice. Choosing a healthier carb option is also a good strategy. I always like making healthier substitutions. Keeping roasted veggies that are well seasoned can stop a carb craving in its tracks

Modern Christmas Tree
The color scheme of Victorian xmas décor is also a little different from the American style tree. Although red and green can play a part colors such as gold and silver should be much more predominant. Pink, blue and lavender ornaments are also much more common on a Victorian styled tree than an American country style one.
