This seems to be a simple typo, but since the texcoords are labeled as `STPf` the `DataFormat` should be `DATAFORMAT_FLOAT_VEC3`. Format `XYf_STPf` reflects this properly.
- add 'location' named field to buffer and mesh vertex format tables, replaces 'name' field.
- location numbers are expected to match 'layout (location = #)' qualifiers in vertex inputs in shader code.
- deprecate vertex inputs in shader code that don't have layout location qualifiers.
- love's default vertex attributes use location 0 for position, 1 for texcoord, and 2 for color.
- add new variants of Mesh:attachAttribute, setAttributeEnabled, and isAttributeEnabled which take location numbers instead of names.
Improves draw performance in vulkan and metal backends.
- Add 'buffers' field, to count the total number of graphics buffer objects.
- Add 'buffermemory' field, to estimate the total number of bytes of graphics memory used by all buffers.
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.
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.
Allows buffers created with love.graphics.newBuffer to only allocate VRAM data. Previously they had a copy of their contents in RAM.
Also makes it easier to implement Buffers in other graphics APIs and to implement more types of Buffers in the future.
GLSL 3+ shaders can read from texel buffers by declaring a uniform samplerBuffer variable and calling texelFetch with a 0-based index, in the shader code. All attributes in a texel buffer's format array must have the same data format (e.g. all 'floatvec4' formats).
Shader:send accepts a texel Buffer for samplerBuffer uniforms.
Added 'texelbuffer' to love.graphics.getSupported (requires GLSL 3+ and desktop OpenGL).
Added 'texelbuffersize' to love.graphics.getSystemLimits. Returns the max number of values in a texel buffer (array length multiplied by the number of attributes declared in the buffer's format array).
