Alex Szpakowski 9c717cc3a3 Changed SpriteBatch:add/set to do an internal bind, and love.graphics.draw(SpriteBatch) to do an internal unbind. Removed SpriteBatch:bind/unbind, and added SpriteBatch:flush.
Resolves issue #886.

Alex Szpakowski 408a593113 Added support for several specific Canvas formats. Also added love.graphics.hasCanvasFormat.
The list includes RGBA with 4-bit components, RGBA with 10-bit R, G, and B components and a 2-bit alpha component, RGB with 9-bit RGB components and a 5-bit exponent component (for HDR rendering), and several more.

Alex Szpakowski f30a0d72f0 Added Shader:getExternVariable(name).
Returns the base type name ('float', 'image', etc.), the number of components (2 for a vec2), and number of array elements (1 for a non-array variable) for the extern variable with the specified name in the shader.

Returns nil if the variable either doesn't exist or was optimized out by the driver's shader compiler.

Alex Szpakowski e7947d9d2e Pulled Mesh:set/getInstanceCount from 0.9.1 for now.
The feature is difficult to use well unless custom vertex attributes are added.

Alex Szpakowski caa61563cc OpenGL 2.1 is now required to use love.graphics (resolves issue #779.)
Removed love.graphics.isSupported("canvas", "shader", "npot", "subtractive", and "mipmap"), since those features are all guaranteed by the minimum system requirements.

Alex Szpakowski 6259e38d84 Meshes will now use the smallest integer data type possible for index buffer (vertex map) values, instead of always using 32-bit integer numbers. 2014-02-12 02:22:57 -04:00
Alex Szpakowski 615492540d Added ParticleSystem:setRelativeRotation. If enabled, particle rotations and angles will be relative to their current velocities. 2014-02-06 05:46:47 -04:00
Alex Szpakowski b625bb6624 moved Mesh:setWireframe to love.graphics.setWireframe (affects all draws until it's disabled.)
Wireframe mode should only be used for debugging: the wireframe lines behave differently than regular lines, their widths aren't affected by the graphics scale, and the mode isn't available on OpenGL ES.

Alex Szpakowski ce4fdf4ac9 Added sRGB (gamma-correct) support for Images, Canvases, and the main screen.
love.graphics.newImage(path, “srgb”) creates a new Image whose texels are treated as being in the sRGB color space, so they are linearized when drawing/sampling from the image.

love.graphics.newCanvas(w, h, “srgb”) creates a new Canvas whose texels are treated as being in the sRGB color space, so drawing to the Canvas does a linear->sRGB conversion (but blends linearly), and sampling from it (drawing it or using it in a shader) converts from sRGB to linear space.

The "srgb" window flag does the same as Canvases for the main screen.

Alex Szpakowski a7ed581204 Reverted ParticleSystem:setPosition’s functionality to 0.9.0’s beheaviour, added ParticleSystem:moveTo which has the new behaviour (new particles spawn in a line between the old position and where the emitter was moved to.) 2014-01-28 03:20:08 -04:00
Alex Szpakowski 6b538b5827 The emission rate for ParticleSystems is no longer restricted to integer numbers. 2014-01-27 23:42:26 -04:00
Alex Szpakowski d70023e350 Enable OpenGL’s debug output when the LOVE_GRAPHICS_DEBUG environment variable is ‘1’. Resolves issue #607. 2014-01-27 23:30:16 -04:00
Alex Szpakowski c5c788e976 Added a built-in variable readable in shaders: ‘love_ScreenSize’. Its x and y components contain the width and height of the current viewport. Resolves issue #841. 2014-01-27 02:58:34 -04:00
Alex Szpakowski 988404e4ca Added love.graphics.getSystemLimit (resolves issue #840). Deprecated love.graphics.getMaxPointSize.
love.graphics.getSystemLimit currently accepts these enum strings: “pointsize”, “texturesize”, “multicanvas”, and “canvasfsaa”.

Alex Szpakowski 7556fde5e6 Added antialiasing (MSAA) support to Canvases via a new optional parameter. Added Canvas:getFSAA. 2014-01-27 01:31:41 -04:00
Alex Szpakowski ba7e69d776 Added Mesh:setDrawRange(min, max) and Mesh:getDrawRange().
If no vertex map is set, this restricts the drawn vertices to those whose indices in the vertex array are between [min, max] inclusive.
If a vertex map is set, this restricts the values used in the vertex map to those whose indices in the vertex map array are between [min, max] inclusive.

Added Mesh constructor variant: love.graphics.newMesh(vertexcount, texture, drawmode). Creates a Mesh with a certain number of vertices with x,y,u,v,r,g,b,a values of (0,0,0,0,255,255,255,255).
2014-01-21 06:16:47 -04:00
Alex Szpakowski 73f1ce0d40 Added instancing support to Meshes via Mesh:setInstanceCount. Added a new built-in variable to vertex shaders: int love_InstanceID.
love.graphics.draw(mesh) will draw the mesh instancecount times, using hardware instancing when available. The only way to draw individual instances differently from each other is to use the love_InstanceID variable in a vertex shader.

Added love.graphics.isSupported(“instancing”). Hardware instancing is supported if true, otherwise a (slower) pseudo-instancing fallback is used internally when drawing instanced meshes.

Alex Szpakowski 29f47d9a10 Changed particle spawning behaviour in ParticleSystems to spawn at an interpolated position between the location at the previous update and the current one. This results in much smoother behaviour when moving a ParticleSystem constantly via ParticleSystem:setPosition.
Also fixed particle spawning to better fill up the buffer.
