Sasha Szpakowski 42812ad521 Add texture views. Fixes #2022.
Add love.graphics.newTextureView(basetexture, viewsettings). Requires GLSL4 support.
Add 'viewformats' boolean setting to texture setting tables.
Add Texture:hasViewFormats.

The viewsettings table has the following fields:
  format = nil, -- set this to a pixel format to override the base format. It must have the same number of bytes per pixel as the original, and the 'viewformats' setting on the original texture must be true for this to work. Cannot be used for compressed or depth/stencil textures.
  type = nil, -- set this to a texture type to override the base texture type. 2d base textures can make [2d, array] views. [array, cube] base textures can make [2d, array, cube] views.
  mipmapstart = nil, -- set to a number to use a less detailed mipmap level as a base.
  mipmapcount = nil, -- set to a number to override the number of mipmaps in the texture view.
  layerstart = nil, -- set to a number to use a specific layer or cube face as a base.
  layers = nil, -- set to a number to override the number of layers in an array texture view.

Sasha Szpakowski 04462ece30 graphics: clean up some stencil code 2024-01-04 21:35:52 -04:00
Sasha Szpakowski 9b5851e039 Move current love.graphics.setStencilMode functionality to setStencilState.
Add new higher level love.graphics.setStencilMode function.
- Add love.graphics.setStencilMode(mode [, value = 1])
- Add love.graphics.setStencilMode().
- Add mode, value = love.graphics.getStencilMode().

The possible modes are "off" (same as no parameters), "draw", and "test".
The "draw" mode disables color writes and sets the stencil state to ("replace", "always") using the given value.
The "test" mode enables color writes and sets the stencil state to ("keep", "equal") using the given value to compare to.

Sasha Szpakowski dbc7d7f3ca Add love.graphics.newMesh variant to create a Mesh from existing Buffers.
This allows a Mesh to be created that doesn't have its own internal vertex buffer and purely references other vertex buffers instead.

The prototype looks like this:
mesh = love.graphics.newMesh(attributelist, drawmode)

where attributelist is an array of tables each with the following fields, similar to Mesh:attachAttribute:
{
    buffer = vertexbuffer,
    name = "VertexPosition", -- the name this vertex attribute will use in a shader
    nameinbuffer = nil, -- the name of the attribute in the vertex buffer. Defaults to the name field.
    step = nil, -- vertex attribute step ("pervertex" or "perinstance"), defaults to "pervertex".
    startindex = nil, -- 1-based array index within the given vertex buffer where the attribute data will start being pulled from during rendering. Defaults to 1.
}

Sasha Szpakowski 96040b2b2a Fix list of data types in the error message when using an invalid vertex data type in the deprecated type+component count vertex format declaration. 2023-09-09 13:22:45 -03:00
Sasha Szpakowski 0b48dacb4e Remove convenience constructor functions for vertex and index buffers.
love.graphics.newVertexBuffer and newIndexBuffer don't do enough to justify their existence since love.graphics.newBuffer already covers all buffer creation functionality.

1-based indices in newIndexBuffer versus 0-based indices in newBuffer(..., {index=true}) was also confusing.

Sasha Szpakowski 2178b634c8 Add functions for indirect draws and compute dispatches.
Resolves #1879.

- Add an 'indirectdraw' boolean field to the graphics feature support table returned by love.graphics.getSupported. This is almost always supported when compute shaders are supported, except on a few older phones.

- Add an 'indirectarguments' boolean field to the settings table in love.graphics.newBuffer.

- Add love.graphics.dispatchIndirect(shader, argumentsbuffer [, argumentsindex = 1]).
    The compute dispatch's threadgroup width, height, and depth values are fetched from the buffer (as 3 uints) instead of coming from function parameters.

- Add love.graphics.drawIndirect(mesh, argumentsbuffer, argumentsindex, x, y, ....).
    Vertex or index count, instance count, and other related parameters for drawing the mesh are fetched from the buffer (as 4 or 5 uints depending on whether the mesh has an index buffer) instead of coming from function parameters. It's usually a good idea to keep parameters other than the instance count in sync with what the mesh should be using.

- Add love.graphics.drawFromShaderIndirect(drawmode, argumentsbuffer [, argumentsindex = 1] [, maintexture = nil]) and drawFromShaderIndirect(indexbuffer, argumentsbuffer [, argumentsindex] [, maintexture = nil]).
    Vertex or index count, instance count, and other related parameters are fetched from the buffer as 4 or 5 uints, as above.

For the dispatch indirect arguments buffer, it has to have 3 uint32 elements: { uint threadgroupsX, uint threadgroupsY, uint threadgroupsZ }.

For non-indexed draws, the arguments buffer has to have 4 uint32 elements: { uint vertexCount, uint instanceCount, uint baseVertex, uint baseInstance }. Note that baseInstance should always be set to 0 as many drivers don't support non-zero values.

For draws which use an index buffer, the arguments buffer has to have 5 uint32 elements: { uint indexCount, uint instanceCount, uint firstIndex, uint baseVertex, uint baseInstance }. As above, the baseInstance value should always be 0.

A buffer can be created to have an array of those structures, which can be used with the argumentsindex parameter of the Indirect dispatch/draw functions.

Sasha Szpakowski defe811f62 Allow creating a mipmapped texture with less than the full mip range.
When creating a texture with user-specified mipmaps, it no longer errors if all mipmaps down to 1x1 aren't present.

Added a 'mipmapcount' field to the settings table in newImage and friends (only used when mipmaps are enabled for the texture.) If it's set, only mipmap levels up to the specified count will be created instead of always creating the full range.

Old OpenGL ES 2 devices don't support loading a mipmapped texture without the full mipmap range, so there's a new 'mipmaprange' boolean field in the table returned by love.graphics.getSupported.

Sasha Szpakowski 7a0f6621e7 Initial (WIP) Harfbuzz text shaping integration.
This a significant refactor / rewrite of much of the love.graphics Font code.
Text positioning is now split into TextShaper classes in the love.font module. This isn't exposed to users yet.
BMFonts and ImageFonts use the same text shaping as before (in the new TextShaper API). Fonts loaded via FreeType now use Harfbuzz for text shaping.

The new code isn't at feature-parity with the old code yet. Harfbuzz-based text shaping enables kerning support in more fonts, character combining into ligature glyphs, and directions other than left-to-right (this isn't supported in love yet).

Sasha Szpakowski f17d3d94f1 Rename love.graphics Text objects to TextBatch.
The name Text is too generic compared to what they're designed for, it made people unnecessarily confused about their purpose.

Alex Szpakowski 3a5c3df02f Add sync and async texture and buffer readback APIs.
- Add imagedata = love.graphics.readbackTexture(texture, [slice, mipmap, x, y, w, h, [dest, destx, desty]]).
- Add readback = love.graphics.readbackTextureAsync(texture, [slice, mipmap, x, y, w, h, [dest, destx, desty]]).
- Add bytedata = love.graphics.readbackBuffer(buffer, [offset, size, [dest, destoffset]]).
- Add readback = ove.graphics.readbackBufferAsync(buffer, [offset, size, [dest, destoffset]]).
- Deprecate Texture:newImageData.

The async variants return a new GraphicsReadback object. It has the following methods:
- isComplete()
- hasError()
- wait()
- getBufferData()
- getImageData()
- update() (called automatically every frame by love, not normally needed).

Support notes:
- readbackBuffer and readbackBufferAsync require buffer copying support.
- readbackTexture with a render target (canvas) is always supported. readbackTexture with a non-render-target requires copy-texture-to-buffer support.
- readbackTextureAsync with a render target requires copy-render-target-to-buffer support. readbackTextureAsync with a non-render-target requires copy-texture-to-buffer support.

Alex Szpakowski 0fa00e0bdc love.graphics.newShader: add a compile options table parameter.
The only field currently read from the table is 'defines', which can contain either an array of define names, or name-value pairs.
For example: newShader(file, {defines={"MYFEATURE_ENABLED", MYSETTING=1}})

Fixes #1577

Alex Szpakowski 6dbb7fa5de Add love.graphics.setStencilMode. Remove old stencil API.
- Add setStencilMode(drawaction, comparemode, value = 0, readmask = 0xFF, writemask = 0xFF).
- Add getStencilMode.
- Remove love.graphics.stencil.
- Remove love.graphics.set/getStencilTest.

Note that the new setStencilMode API does not clear the stencil buffer, and does not turn off color writes (it can still be done manually), unlike love.graphics.stencil.

Fixes #1161.
Fixes #1251.

Alex Szpakowski 173fe3dab5 Add a love.graphics.setColorMask variant which accepts a single bool.
Remove the variant which accepted no args - it would be too confusing because setColorMask(false) does the opposite of what setColorMask(nil) used to do.

Alex Szpakowski ecbc5ca7f6 Add love.graphics.getQuadIndexBuffer.
love's pre-generated quad index buffer is useful when combined with drawShaderVertices. Note that it uses 16 bit indices so it can only draw up to 16k quads in a single call.
2022-01-03 16:22:08 -04:00
Alex Szpakowski 0c4be3d5e3 Add love.graphics.drawShaderVertices (name subject to change).
It draws a number of vertices, or a number of indices from an index buffer, without using any vertex data from a vertex buffer. A custom shader is required while using it.

It is useful when a custom GLSL3 vertex shader which uses love_VertexID is used to pull or compute per-vertex information from other sources.
