#define USE_FEATURE_A
but
#define LOOP_ITERATIONS 16
So, speaking shortly, I want to pass a macro *with* a value so that my shader can, for instance, nicely unroll a loop for which I know a number of iterations upfront. I don't want to declare such a define in the shader directly, because the shader does not have this numeric information - application, right before it compiles the shader, nows.
I tried something like:
D3D10_SHADER_MACRO macros[2];
macros[0].Definition = "LOOP_ITERATIONS";
macros[0].Name = "16";
macros[1].Definition = macros[1].Name = NULL;
or:
D3D10_SHADER_MACRO macros[2];
macros[0].Definition = "LOOP_ITERATIONS 16";
macros[0].Name = "";
macros[1].Definition = macros[1].Name = NULL;
but none of this works. Any idea?
On a side note: what's the purpose of macro's Name anyway?
