Requirements: . * GHC 7.6+ . * OpenGL 3.3 . You need to use `-threaded` flag in executables that use this library. . Here are the most important features of this library: . * Safe and automatic finalization of OpenGL resources . * No implicit state (that is, no glBind* mess or equivalent). There is a monad for mass-rendering that has implicit state but the state is localized to running of that monad. (see Caramia.Render). . * Only vanilla OpenGL 3.3 required. Some extensions will be used if they are available. . Here are some curious features that you might find useful. . * This library plays nice with other OpenGL libraries. It does not mess up the implicit OpenGL state (except for aforementioned rendering monad). . * This library does not create an OpenGL context. You can use whatever library you want to create an OpenGL context as long as it can get an OpenGL 3.3 context. You may be interested at looking at the tests in this package to see how to use this with the `sdl2` package. . * Operations are generalized over `MonadIO`. Works on top of pure `IO` and also in your custom monad stacks, if they have `MonadIO` at bottom. . (At least) the following OpenGL concepts are present in this library: . * Buffer objects (you can do low-level mapping and use raw pointers) . * Geometry, vertex and fragment shaders . * Indexed and non-indexed rendering . * Framebuffers . * Textures (with many topologies, 1D, 2D, 3D, texture arrays, cube textures; we also have buffer textures and multisampling textures) . * Vertex array objects . * Blending, stencil, depth and cull tests . * Instanced rendering . * Synchronization objects . * Query objects . Some notable missing features: . * Tesselation shaders. This is an OpenGL 4.x feature but we could add it. . * Using shaders with transform feedback. . * Multi-threaded rendering. . This library tries to avoid including obsolete or redundant features of OpenGL. . One major flaw(?) of this library is that OpenGL resources cannot be easily released promptly. This may or may not be a problem for you. OpenGL resources may refer to each other behind the scenes so if we implement a mechanism to release resources early, this mechanism needs to take care of resources referring to each other. . Expect bugs. While this library has been tested in some of the author's toy programs, the library currently lacks automatic tests. flag build-toys default: False description: Build some toy programs to test and play with. source-repository head type: git location: https://github.com/Noeda/caramia.git library exposed-modules: Graphics.Caramia Graphics.Caramia.Blend Graphics.Caramia.Blend.Internal Graphics.Caramia.Buffer Graphics.Caramia.Buffer.Internal Graphics.Caramia.Color Graphics.Caramia.Context Graphics.Caramia.Framebuffer Graphics.Caramia.Framebuffer.Internal Graphics.Caramia.ImageFormats Graphics.Caramia.ImageFormats.Internal Graphics.Caramia.Internal.ContextLocalData Graphics.Caramia.Internal.FlextGL Graphics.Caramia.Internal.OpenGLCApi Graphics.Caramia.Internal.OpenGLDebug Graphics.Caramia.Internal.TexStorage Graphics.Caramia.Memory Graphics.Caramia.Prelude Graphics.Caramia.Query Graphics.Caramia.Render Graphics.Caramia.Render.Internal Graphics.Caramia.Resource Graphics.Caramia.Shader Graphics.Caramia.Shader.Internal Graphics.Caramia.Sync Graphics.Caramia.Texture Graphics.Caramia.Texture.Internal Graphics.Caramia.VAO Graphics.Caramia.VAO.Internal ghc-options: -Wall -fno-warn-name-shadowing build-depends: base >=4.6 && <5.0.0.0 ,bytestring >=0.10 && <1.0 ,containers >=0.5 && <1.0 ,exceptions >=0.6 && <1.0 ,lens >=4.6 && <5.0 ,linear >=1.15 && <2.0 ,OpenGLRaw >=1.5 && <2.0 ,semigroups >=0.15 && <1.0 ,text >=0.9 && <2.0 ,transformers >=0.4 && <1.0 ,vector >=0.10 && <1.0 if !os(windows) build-depends: unix >=2.7 && <3.0 hs-source-dirs: src default-language: Haskell2010 if os(darwin) frameworks: OpenGL -- This is just a dumping ground test that does stupid things.
