Class ShaderGraphResolver

ShaderGraphResolver is a class that resolves the shader node graph and generates shader code. It provides functionality to convert a graph of shader nodes into complete vertex and fragment shaders.

Methods

StaticcreatePixelShaderCode

  • createPixelShaderCode(pixelNodes, isFullVersion?): undefined | string

  • Creates a complete fragment/pixel shader code from the given pixel nodes. This method performs topological sorting, generates function definitions, and constructs the main shader body for fragment processing.

    Parameters

    • pixelNodes: AbstractShaderNode[]

      Array of shader nodes that contribute to fragment processing

    • isFullVersion: boolean = true

      Whether to generate a full version with all prerequisites and boilerplate

    Returns undefined | string

    Complete fragment shader code as a string, or undefined if generation fails

StaticcreateVertexShaderCode

  • createVertexShaderCode(vertexNodes, varyingNodes, isFullVersion?): undefined | string

  • Creates a complete vertex shader code from the given vertex and varying nodes. This method performs topological sorting of nodes, generates function definitions, and constructs the main shader body with proper variable declarations and connections.

    Parameters

    • vertexNodes: AbstractShaderNode[]

      Array of shader nodes that contribute to vertex processing

    • varyingNodes: AbstractShaderNode[]

      Array of shader nodes that pass data from vertex to fragment stage

    • isFullVersion: boolean = true

      Whether to generate a full version with all prerequisites and boilerplate

    Returns undefined | string

    Complete vertex shader code as a string, or undefined if generation fails

StaticgenerateShaderCodeFromJson

  • generateShaderCodeFromJson(json): undefined | {
        pixelShader: string;
        vertexShader: string;
    }

  • Generates complete vertex and fragment shader code from a JSON shader node graph definition. This is the main entry point for converting a serialized shader graph into executable shader code. The method performs the full pipeline: node construction, dependency resolution, stage assignment, and final code generation.

    Parameters

    • json: ShaderNodeJson

      JSON representation of the shader node graph containing nodes and connections

    Returns undefined | {
        pixelShader: string;
        vertexShader: string;
    }

    Object containing both vertex and fragment shader code, or undefined if generation fails

    Example

    const shaderCode = ShaderGraphResolver.generateShaderCodeFromJson(graphJson);
    if (shaderCode) {
      const { vertexShader, pixelShader } = shaderCode;
      // Use the generated shaders...
    }
