####SharpShaders - A library for crafting GPU shader code in F#.

####Why write shaders in F#?

• Targeting multiple platforms
• Code Sharing
• Unit Testing
• Syntactic sugar
• Because it's FUN!

####The Secret Sauce: Code Quotations ####Examples

• Basic Gouraud Shader
• Blinn Phong Shader
• Higher order functions

####Future Work

• Runtime code compilation
  • It should be possible to edit an F# shader and immediately see the result at runtime (if the changed shader compiles of course)
• Geometry, Hull, Domain, Compute Shaders
• Dynamic Shader Linking
  • The Dynamic attribute on shader functions should indicate that this function can be swapped at runtime

[<Dynamic>]
let marble = ...
[<Dynamic>]
let lumpy = ...
[<Dynamic>]
let crinkled = ...

let mutable surface = marble

[<PixelShader>]
member m.pixel(input:PSInput) =
    surface input

At runtime the surface shader can be swapped:

ps.surface <- ps.crinkled
