Alex Szpakowski a31b500b03 Simplify quad drawing code, and use glDrawElementsBaseVertex when available. 2017-12-24 22:05:10 -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.

Alex Szpakowski 9fe81ad922 Allow a temporary/internal depth buffer to be used when a Canvas is active, similar to how temporary stencil buffers are allowed.

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.

Also fixed Canvas MSAA (resolves issue #1271).

- Add new love.graphics.setCanvas variants: setCanvas(canvas, slice), and setCanvas(canvastable) where canvastable is in the format: {{canvas1, layer=2}, {canvas2, face=5}}

- Add Texture:getTextureType, getDepth, getLayerCount, getMipmapCount, and getFormat.

- Remove Image:getData and Image:refresh.

- Update Canvas:newImageData to accept a slice argument.

- Add love.image.newCubeFaces(imagedata).

Alex Szpakowski bea7cfdaab Add low-level hardware instancing support to Meshes.
Add “instancing” Graphics Feature constant.

Add love.graphics.drawInstanced(mesh, instancecount, x, y, …) which draws the mesh multiple times in a single draw call. Each instance of the mesh will appear in the exact same spot unless one of the following are used:

- Add an optional vertex attribute step type argument to Mesh:attachAttribute. “pervertex” is the default. “perinstance” causes the attribute to be per-instance instead of per-vertex, when the mesh is drawn.

- Add love_InstanceID as a built-in read only int variable in GLSL 3 vertex shaders. It is always 0 except when a Mesh is drawn with more than 1 instance specified in the draw call. It can be used to manually compute or index into per-instance values in a shader.

Alex Szpakowski 731b5d5cf0 Added support for GLSL 3 shaders (GLSL 3.30 and GLSL ES 3.00).
To use GLSL 3 in a shader, the first line of the shader has to be: #pragma language glsl3

glsl1 is the default language.

Added “glsl3” graphics feature as part of the table returned by love.graphics.getSupported().

Added love.graphics.validateShader(boolean gles, shadercode). It returns a boolean along with an error string if the shader code has errors for its target language and platform (gles or desktop).

Implemented support for Core Profile OpenGL 3.3 in love.graphics.

Alex Szpakowski d26002f5cc Revamped and streamlined retina / high-DPI support (resolves issue #1122).
With the highdpi window flag enabled on a retina-capable display and OS, content should now appear to the user at the same size and in the same positions as with the flag disabled.

As a result, mouse and touch coordinates, Texture and graphics dimensions, and the graphics coordinate system now use pixel density-scaled units instead of pixels. Raw pixel units should generally only be used for things such as shader algorithms which execute per-pixel and rely on accurate pixel dimensions. love.window.fromPixels and friends typically don’t need to be used anymore.

Images, Canvases, and Fonts can have an optional explicit ‘pixel density’ set when creating them. This allows for easily loading high pixel density content which displays at the same size as regular or low pixel density content.

API changes:

- Added Texture:getPixelWidth/getPixelHeight/getPixelDimensions and Texture:getPixelDensity. Texture:getWidth/getHeight return the pixel density-scaled width and height (as it will appear on the screen when drawn) rather than the number of pixels on each texture dimension.

- Added love.graphics.getPixelWidth/getPixelHeight/getPixelDimensions.

- Added optional ‘pixeldensity’ field to the settings table parameter of love.graphics.newImage. It defaults to 1, or if the file the Image was loaded from has “@2x”, “@3x”, etc. at the end of its name, it uses that number as the pixel density scale by default.

- love.graphics.newCanvas now takes a table as its third parameter, with fields “format”, “msaa”, and “pixeldensity”. pixeldensity defaults to the main screen’s pixel density. The width and height parameters specify the visual size that the Canvas will be drawn at / can be drawn to (pixel density-scaled units).

- love.graphics.newVideo accepts a table as its second parameter, with optional fields “audio” and “pixeldensity”. pixeldensity defaults to 1.

- love.graphics.newFont variants have an optional pixeldensity parameter at the end of the argument list. For TrueType fonts this defaults to the current pixel density scale of the screen, and for BMFonts and ImageFonts this defaults to 1.

- Added Font:getPixelDensity.

- Renamed love.window.getPixelScale to love.window.getPixelDensity.

Alex Szpakowski 0d2e08baff Implement automatic batching for points, lines, shapes, and images/quads.
The above are batched together into a single draw call when called without other drawing calls in between, as long as the following criteria are met:

- The texture is the same.
- The primitive type is the same (points cannot be batched with non-points).
- The love.graphics state is the same (aside from the current color - i.e. setColor - and the transform state).
- The active shader’s uniform values are the same.

You can examine the ‘drawcalls’ field of love.graphics.getStats() to help determine if your code is allowing for optimum batching.

- love.graphics.push can accept an optional Transform as a second argument, which will apply the Transform after pushing the matrix stack,
- Shader:send can accept Transform objects when sending to a mat4 uniform variable.
