bjorn cdecc1bae7 Add defer system; Rework exceptions; util cleanup; 
Defer can be used to clean up resources when an error occurs.

bjorn 67e228125b Add d24 TextureFormat; 
LÖVR uses d32f by default, but that's not guaranteed to be supported.

However, GPUs must support either d32f or d24, so we can fall back to
d24 reliably.

bjorn 35f97f08f3 glTF: support glb models without BIN chunk; 2024-01-29 00:29:23 -08:00
bjorn 40d85c6a16 Model uses sn10x3 normals and tangents; 
This shaves 20 bytes off of each model vertex, or around 40% savings.
The vertex size is also a power of two which results in extreme amounts
of style points.

bjorn 90a14478a3 lovrImageCreateRaw takes sRGB flag; Fix readback encoding; 
Roundtripping pixels through a readback preserves sRGB encoding.

bjorn f0686f0115 Update msdfgen; Orient contours properly; 
This fixes issues where some fonts would have glyphs with weird windings
and they would get rendered inside-out.

Unfortunately updating msdfgen increased its size by a factor of 2-3x.

bjorn 072452a4da Fix issue where OBJ UVs are upside down; 
Most OBJ loaders use OpenGL texture coordinate conventions.

After switching to Vulkan, the UV origin became upper-left and images no
longer needed to be flipped on import.  This means that the OBJ importer
now needs to flip its UVs to compensate.  Somehow, no one noticed until
now!  Most people are using glTF I guess.

bjorn 4892d228b3 WIP; 2023-07-24 15:34:44 -07:00
bjorn be795c0ebd Change vec3 back to 3 floats; Clean up maf/vectors; 
The "vec3 is 4 floats" thing was consistently confusing to people.  It's
reverted everywhere except for Curve.

maf now has full sets of methods for vec2/vec3/vec4, for consistency.

Vector bindings now use luax_readvec* helper functions for the
number/vector variants, and use maf for most functionality, which cleans
things up a lot.

bjorn 06811dcb1a Fix lovr.graphics.newModel when model has unused meshes; 
Prefer n^2 loop over a weird sentinel value that wasn't always getting written over.

s-ol 7dbdda1205 Fix node indexing for GLTF models with multiple root nodes 2022-11-14 08:02:13 -08:00
bjorn cacc5eae71 ModelData:getTriangles reuses vertices better; 
ModelData:getTriangles currently adds a fresh set of vertices for every
mesh in a node.  This is technically correct, but it wastes space when 2
nodes reference the same set of vertices with different index buffers,
which is pretty common when a node has multiple materials.  It also
breaks ODE, who doesn't like it when vertices outnumber indices too
much.

bjorn 2e0b5a4efa Flip msdf glyphs; 
They don't look right when using a negative y scale for some reason,
even though the rendering was still working.

bjorn bcde681710 Mark ASTC textures as sRGB; 
They don't contain this metadata, but marking as sRGB is more reasonable
than not.

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.
