bjorn 5c4fc79242 mv lovr.graphics.init lovr.graphics.initialize; 
init is undocumentable due to Lua conventions.

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 ea30100c31 rm texture variant of newMaterial; 
Does not make sense anymore now that Pass:setMaterial(Texture) exists.

bjorn 7aebde2f92 Fix StencilAction; 2022-08-26 22:23:04 -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 f45706f875 Change Buffer format 'name' to 'location' string; 
Name is confusing because it seems like it supports key/value setting.

bjorn f515346e20 Rename CoordinateSpace; 
It's now OriginType, and global -> root and local -> parent.
 2022-08-17 22:33:43 -07:00
bjorn 5799b0effb Rename setBackground back to setBackgroundColor; 
The "fancy background" idea won't go here.

bjorn 143b0ba664 Fix DefaultShader initialization; 2022-08-12 18:26:47 -07:00
bjorn 7e5221492d rm pointSize from Material; 
It's weird, and about as inconvenient as just putting it in the shader.

bjorn 019814e2c1 Change the way modules are destroyed; 
They are now destroyed explicitly after tearing down the Lua state
instead of relying on finalizers.  It's definitely annoying to make it
coordinated in a centralized way like this instead of being distributed,
but there's not really any reliabel way to ensure that graphics objects
are destroyed before the graphics module/device is destroyed, which is a
problem.

bjorn 16860e8ef5 rm stats; 
These stats don't make sense right now.
 2022-08-04 07:59:07 -07:00
bjorn acd87a5e5c lovr.graphics.present; 
It's nice to have an explicit action for presentation.
 2022-08-04 00:06:54 -07:00
bjorn 89312c1c4b Add on-disk shader cache; 
Set t.graphics.shadercache to true (the default) and lovr will
read/write a shader cache file from/to disk.

bjorn 4ee092e81b Make Pass a regular object; 
It uses newPass instead of getPass.  Temporary objects had lifetime
issues that were nearly impossible to solve.  And normal objects are
easier to understand because they behave like all other LÖVR objects.

However, Pass commands are not retained from frame to frame.  Pass
objects must be re-recorded before every submit, and must be reset
before being recorded again.

Pass objects now provide a natural place for render-pass-related info
like clears and texture handles.  They also allow more information to be
precomputed which should reduce overhead a bit.

It is now possible to request a stencil buffer and antialiasing on the
window and headset textures, via conf.lua.

lovr.graphics.setBackground should instead set the clear color on the
window pass.  Though we're still going to try to do spherical harmonics
in some capacity.

There are still major issues with OpenXR that are going to be ironed
out, and the desktop driver hasn't been converted over to the new
headset Pass system yet.  So lovr.headset integration is a bit WIP.

bjorn f89b1811aa Adjust default Buffer field locations; 
I guess it's better to match them up with the default attributes.
In most cases you're going to want to manually specify them with names
or numbers anyway.

bjorn f7d7281e70 Add index16/index32 FieldTypes; 
Similar to u16/u32 but are 1-indexed when written using tables.

Doesn't 100% work, Buffers are kind of a mess, ugh.

bjorn cbe24f482f Adjust font uvs; 
- Padding is automatically computed from spread.
  - Spread increases detail at small sizes.
  - Remove failure cases where padding < spread/2
- UVs are un16x2, making room for color
- Don't center glyphs inside their atlas bounding box
- Cache normalized UVs and update them (for glyphs and vertices) when
  the atlas changes size.
  - Updating the UVs is UGLY and duplicates a lot of code.  It may be
    better to normalize the UVs on the fly, or just re-render the entire
    string if the atlas is updated.
