pixelShaderDefinitions

  • get pixelShaderDefinitions(): "\n fn outColor(inColor: vec4<f32>) {\n rt0 = inColor;\n }\n " | "\n void outColor(in vec4 inColor) {\n rt0 = inColor;\n }\n "

  • Gets the pixel/fragment shader function definitions for color output. Returns appropriate function definition based on the current process approach (WebGL/WebGPU).

    Returns "\n fn outColor(inColor: vec4<f32>) {\n rt0 = inColor;\n }\n " | "\n void outColor(in vec4 inColor) {\n rt0 = inColor;\n }\n "

    Shader code string containing the outColor function definition

vertexShaderBody

  • get vertexShaderBody(): string

  • Gets the vertex shader body code. Currently returns empty string as no additional vertex processing is needed.

    Returns string

    Empty shader body string

vertexShaderDefinitions

  • get vertexShaderDefinitions(): "\n fn outPosition(inPosition: vec4<f32>) {\n output.position = inPosition;\n }\n " | "\n void outPosition(in vec4 inPosition) {\n gl_Position = inPosition;\n }\n "

  • Gets the vertex shader function definitions for position output. Returns appropriate function definition based on the current process approach (WebGL/WebGPU).

    Returns "\n fn outPosition(inPosition: vec4<f32>) {\n output.position = inPosition;\n }\n " | "\n void outPosition(in vec4 inPosition) {\n gl_Position = inPosition;\n }\n "

    Shader code string containing the outPosition function definition

Methods

getPixelShaderBody

  • getPixelShaderBody(): string

  • Gets the pixel/fragment shader body code. Currently returns empty string as no additional fragment processing is needed.

    Returns string

    Empty shader body string

StaticgetAssignmentStatement

  • getAssignmentStatement(varName, inputSocket): string

  • Generates variable assignment statement with proper type declaration. Creates appropriate syntax for both WebGL (GLSL) and WebGPU (WGSL) based on the current process approach.

    Parameters

    • varName: string

      The name of the variable to declare

    • inputSocket: Socket<string, CompositionTypeEnum, ComponentTypeEnum, SocketDefaultValue>

      The socket containing type and default value information

    Returns string

    The variable assignment statement string

StaticgetAssignmentVaryingStatementInPixelShader

StaticgetAssignmentVaryingStatementInVertexShader

  • getAssignmentVaryingStatementInVertexShader(inputNode, varNames, j): string

  • Generates varying variable assignment statement for vertex shaders. Creates code to write varying variables that will be passed to fragment shader.

    Parameters

    • inputNode: AbstractShaderNode

      The shader node that provides the varying variable

    • varNames: string[]

      Array of variable names to assign

    • j: number

      Index of the current variable in the varNames array

    Returns string

    The varying variable assignment statement string for vertex shader

StaticgetInstance

StaticgetMainBegin

  • getMainBegin(isVertexStage): string

  • Generates the main function beginning code for vertex or fragment shaders. Handles differences between WebGL (GLSL) and WebGPU (WGSL) shader languages.

    Parameters

    • isVertexStage: boolean

      True if generating code for vertex shader, false for fragment shader

    Returns string

    The shader code string for the main function beginning

StaticgetMainEnd

  • getMainEnd(isVertexStage): "\n return output;\n}\n" | "\n return rt0;\n}\n" | "\n}\n "

  • Generates the main function ending code for vertex or fragment shaders. Handles differences between WebGL (GLSL) and WebGPU (WGSL) shader languages.

    Parameters

    • isVertexStage: boolean

      True if generating code for vertex shader, false for fragment shader

    Returns "\n return output;\n}\n" | "\n return rt0;\n}\n" | "\n}\n "

    The shader code string for the main function ending

StaticgetMainPrerequisites

StaticgetPixelPrerequisites

  • getPixelPrerequisites(shaderNodes): string

  • Generates fragment/pixel shader prerequisites including definitions and varying variable declarations. Creates appropriate code for both WebGL (GLSL) and WebGPU (WGSL) based on the current process approach.

    Parameters

    • shaderNodes: AbstractShaderNode[]

      Array of shader nodes used to generate varying variables for WebGPU

    Returns string

    The complete fragment shader prerequisites code string

StaticgetVertexPrerequisites

  • getVertexPrerequisites(shaderNodes): string

  • Generates vertex shader prerequisites including definitions, vertex inputs, and uniform declarations. Creates appropriate code for both WebGL (GLSL) and WebGPU (WGSL) based on the current process approach.

    Parameters

    • shaderNodes: AbstractShaderNode[]

      Array of shader nodes used to generate varying variables for WebGPU

    Returns string

    The complete vertex shader prerequisites code string
