bjorn 116d14cdf8 Details; 2023-06-24 11:26:09 -07:00
bjorn 6862b8c970 Change cofactor/normal matrix to mat3; 
This means per-draw uniform data is 128 bytes now!

bjorn 6c252a47b8 Don't declare builtin flags in compute shaders; 
They aren't used, and increase file size and clutter up disassembly.
 2023-04-05 21:53:39 -07:00
bjorn a2b12c9e7c Vertex tangents don't require normalMap flag anymore; 2023-03-31 19:23:20 -07:00
bjorn 6de1c624b4 Scope shader macros by the stage they're valid in; 
Leads to better error messages if you try to use e.g. DefaultPosition in
a fragment shader.

bjorn 7027defe3c rm attachmentCount shader flag; 
It doesn't work as intended (due to glslang issues?).  The current way
to write a shader that uses multiple attachments is to declare multiple
output variables, which is a little better because you can name them
however you want and customize the type.

It would be nice to be able to support a "void" entrypoint for multiple
attachments so you don't need to awkwardly return the first target's
color, but I can't find a way around this right now.

bjorn cd04060467 Use correct roughness for indirect specular lighting; 2022-09-23 23:58:47 -07:00
bjorn d905b649a4 Lighting helper fixes; 2022-09-23 23:44:31 -07:00
bjorn ef407fd564 Add var shader helper; 
Now you can write var(0) instead of layout(set = 2, binding = 0).
The advantage is less typing and resilience in the event that the
default set changes.
The disadvantage is that now you can't use var.

bjorn 8697466009 Shader flag adjustments; 
- glowTexture is on by default, but still requires the glow flag.
- occlusionTexture is named ambientOcclusion, and is on by default,
  but is still not used by any builtin shaders/helpers.

bjorn 0b0faf6dc6 DefaultColor respects flag_colorTexture; 2022-09-02 15:07:45 -07:00
bjorn 085550da33 Tonemapping, I guess; 2022-08-26 10:34:32 -07:00
bjorn ad7c854571 Add evaluateSphericalHarmonics helper; 2022-08-26 10:28:43 -07:00
bjorn 70aff00a11 Rename shader flags; Add color flags; 2022-08-26 10:28:23 -07:00
bjorn 5a2fe54c04 Improve Pass:fill; 
It can now fill an array texture to a multiview pass, copying to
the corresponding layers.

bjorn ede1036694 Temporary Passes; 
Sigh, back to getPass.  I don't even know at this point.  Basically now
that we came up with a half-solution for temp buffers, it makes sense to
apply this to passes as well, since we aren't going with the workstream
idea and temp passes are more convenient than retained passes.

bjorn 51312f4704 Add attachmentCount/defaultPointSize specialization constants; 2022-08-14 09:43:00 -07:00
bjorn f894c87723 Clamp roughness to .05; 2022-08-13 00:26:18 -07:00
bjorn 13f40a05c3 Update getPixel syntax for array textures; 
vec3 is just kinda weird.

bjorn b51d4e7de7 Normal mapping; 2022-08-12 17:59:06 -07:00
bjorn 7e5221492d rm pointSize from Material; 
It's weird, and about as inconvenient as just putting it in the shader.
 2022-08-09 19:54:54 -07:00
bjorn 0a599ccdd6 Rename PixelColors to PixelColor; 2022-08-09 19:51:53 -07:00
bjorn 63a327c0b2 Add getLighting builtin function to shaders; 2022-08-09 19:49:47 -07:00
bjorn 7efd19c45c Add uniform buffer for global constants; 
So far it has resolution and timestamp.

Broke the nogame shader, need to recompile.
