RavenEmitter

Remarks

A node writes statements, not a shader. It has no idea what stage it is in, what the entry point is called or what the master node did; it emits lines that assign to its own output variables and it stops there. Everything structural is ShaderGraphCompiler's, which is what lets a node be twelve lines and a plugin's node be twelve lines too.

Declarations are requests, not text. A node that needs a uniform or an interpolated value says so and gets the name back; the compiler decides where the declaration goes and emits it once however many nodes asked. Two texture nodes sampling the same property declare one binding, and a graph with no normal node interpolates no normal.

Fields and properties (1)

• public ShaderGraphKind Kind

  What shape the compiler is emitting, which decides what a node may reach.

Methods (6)

• public void Emit(string statement)

  Writes one statement into the pixel stage's body.

• public void Assign(string variable, string expression)

  Declares a value the node computes, and names it.

• public void Import(string package)

  Asks for a Raven package to be in scope, for a node that calls a library function.

• public string Uniform(string name, string type)

  Asks for a material uniform, and gets the name to read it by.

• public string Stage(ShaderStageInput input)

  Asks for an interpolated value from the vertex stage, and gets its name.

• public string Sample(string name, string coordinate)

  Reads a material's texture at a coordinate, however this shape reaches one.
