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 aaab9791d5 Improve backbuffer depth buffer.
- Setting the depth buffer for the backbuffer is now done as a boolean instead of a bit depth integer, in love.conf or love.window.setMode.
- Error if depth writes are enabled when the active canvas setup or backbuffer does not have a depth buffer (now it matches stencil behaviour).
- Don't allocate a backbuffer depth-stencil buffer if they're not requested. Metal also determines the format for that buffer based on which combination of depth and stencil is requested. OpenGL still has to allocate the depth-stencil buffer for the backbuffer all the time, because changing it requires the context to be recreated.

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 8872497561 graphics: handle default textures in high level code.
Previously each backend had to set up default textures with its own code, which needs some care for it to be robust.

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.

slime 99ad576668 metal: implement storage texture support for shaders.
Fixes #1783
2022-10-10 13:47:17 -03:00
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.

Miku AuahDark 405e33a689 Use int instead of PixelFormatUsageFlags for isPixelFormatSupported. 2022-03-05 13:42:20 +08:00
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.
