Alex Szpakowski a31b500b03 Simplify quad drawing code, and use glDrawElementsBaseVertex when available. 2017-12-24 22:05:10 -04:00
Alex Szpakowski 3fb621af95 Always use a 16 bit index array for quad indices, with multiple draws when necessary. See issue #1356. 2017-12-24 15:54:03 -04:00
Alex Szpakowski 7354de2059 Add (low level) functionality to allow rendering 3D Meshes.
- Add love.graphics.setDepthMode(testcomparison, enablewrites).
- Add love.graphics.setMeshCullMode.
- Add love.graphics.setFrontFaceWinding.

Depth testing and depth writes require a depth buffer to work. The mesh cull mode controls whether front/back faces of a mesh are culled. The front face winding determines whether a clockwise or counterclockwise-oriented face in a mesh is considered front facing.

Bart van Strien 9e4374935d Show (short) list of possible enum values when an invalid value is encountered (resolves #1318)
All enum errors have (hopefully) been changed to a luax_enumerror, which has a
fixed error message. If additionally a list of valid options is passed, it
lists that in the error message. For every enum error with few options I've
implemented this using a getConstants call.

This solution has been designed specifically to reduce the number of template
instantiations (as I've been told that was a concern). All new template code
happens in places where there already was an instantiation of the relevant
StringMap. Of course there is still std::vector<std::string>...

Bart van Strien 77663ed847 Replace love.graphics.pop("all") with love.graphics.getStackDepth (resolves #1248 again)
The pop("all") api was a bit awkward, especially considering there's a
push("all") that does something else. I think any use case that benefited from
pop("all") benefits from getStackDepth just as much if not more. There is also
additional functionality, like being able to find the source of a mismatched
push/pop.

Functions which are deprecated will print out a message and show up in a small dialog on-screen, when they're first called. Deprecation output is disabled in fused mode by default, and can be modified with love.setDeprecationOutput(enable).

2017-04-28 21:36:50 -03:00
Alex Szpakowski 7161d600b7 Add mipmapping support to Canvases.
- Added an optional mipmap index argument to the non-table variant of love.graphics.setCanvas, and an optional ‘mipmap’ field to the table variant.
- Canvas:setMipmapFilter now works.
- Added Canvas:generateMipmaps.
- Added Canvas:getMipmapMode.
- Added a new ‘mipmaps’ enum field to the table passed into love.graphics.newCanvas. Accepted values are “none” (default), “manual”, and “auto”.

If a Canvas has the manual mipmap mode, you will either need to render to a mipmap level or call Canvas:generateMipmaps. If it has the auto mode, mipmaps will be automatically generated after rendering to that Canvas. Generating mipmaps is not free.

Alex Szpakowski a0ef2ac28b Add Depth compare / shadow sampler support. Officially this is only supported in glsl3 shaders.
- Add Texture:setDepthSampleMode(comparemode). Only works on textures with depth pixel formats. A texture with the depth sample mode set will only work with a depth sampler.
- Add DepthImage, DepthArrayImage, and DepthCubeImage sampler keywords to glsl3.

Alex Szpakowski 0001b4695e Add new variants of love.graphics.clear for controlling how the depth and stencil buffers are cleared.
- Add love.graphics.clear(r, g, b, a [, stencilvalue, depthvalue]).
- Add love.graphics.clear(color1, color2, …, [, stencilvalue, depthvalue]).
- Add love.graphics.clear(false, stencilvalue, depthvalue).

stencilvalue and depthvalue are either true, false, or a number. True is the default behaviour and clears that buffer to the default value (0 for stencil, 1 for depth), false prevents clearing.

The third variant listed above only clears the depth and/or stencil buffers and not the color buffer.
