- Moves GLSL constant loading code into glsl_shader.c and out of the
over-populated drawprim.c.
- Creates a new file named arb_program_shader.c which will hold code
specific to ARB_vertex_program & ARB_fragment_program.
- Remove the constant loading calls from drawprim.c
- track sampler declarations and store the sampler usage in reg_maps structure
- store a fake sampler usage for 1.X shaders (defined as 2D sampler)
- re-sync glsl TEX implementation with the ARB one (no idea why they diverged..)
- use sampler type in new TEX implementation to support 2D, 3D, and Cube sampling
- change drawprim to bind pixel shader samplers
Additional improvements:
- rename texture limit to texcoord to prevent confusion
- add sampler limit, and use that for samplers - *not* the same as texcoord above
The new function is called in pass 2 (getister counting/maps), and
it's now in baseshader. It operates on all INPUT and OUTPUT registers,
which, in addition to the old vertex shader input declarations covers
Shader Model 3.0 vshader output and pshader input declarations. The
result is stored into the reg_map structure.
Delete the entire namedArrays code path and all its dependencies (one
of which is quite long - storeOrder in drawprim is always FALSE, for
example). Delete declaredArrays, and make its code path the default.
- Based on comments from H. Verbeet
- Changed the distinction from .rgba & .xyzw masks to only use .xyzw
in GLSL shaders. They are interchangeable, and only served to make
the trace look more intuitive, but they don't always apply as-is, so
we'll just leave everything to .xyzw.
- Got rid of the "UseProgramObjectARB(0)" call in drawprim. If there
is no shader set on the next primitive, then that primitive will
call UseProgramObjectARB(0) when it begins to draw.
loading float constants for GLSL.
- DrawPrim is just too big of a function. This separates the passing
of constants to the shader into new functions.
- Fixes an off-by-one error when loading vertex declaration constants
(should be <, not <=)
- Adds a function for GLSL loading of constants (aka Uniforms)
- Adds a GLSL program variable to the stateblock and sets it to 0 (a
future patch will actually create this program)
It is wrong to maintain a mapping from a constant index to a type
field, because different constant types do not share an index -
boolean constant 0 is supposed to co-exist with floating point
constant 0, not replace it. Drawprim and other code using the type
array to decide whether to look up a constant in bools, floats, or
ints is wrong - you can't make that decision based on the index.
Start to add support for DirectX 8 vertex shaders, constants and
registers are now correctly assigned and loaded allowing support for
most basic d3d8 shaders.
- use D3DCOLOR macros instead of using shift + masks
- fix a bug where diffuse.lpData checked instead of specular.lpData
- implement color fixup on ARB VShader compilation code:
-> on input parameters using swizzle
-> add is_color parameter on vshader_program_add_param
