Functions

MeshNormalNodeMaterial.setupDiffuseColor(): void

JSDoc:

/**
     * Overwrites the default implementation by computing the diffuse color
     * based on the normal data.
     */

Returns: void

Calls:

• float (from ../../nodes/tsl/TSLBase.js)
• diffuseColor.assign
• colorSpaceToWorking (from ../../nodes/display/ColorSpaceNode.js)
• vec4 (from ../../nodes/tsl/TSLBase.js)
• directionToColor (from ../../nodes/utils/Packing.js)

Internal Comments:

// By convention, a normal packed to RGB is in sRGB color space. Convert it to working color space. (x4)

Code

setupDiffuseColor() {

        const opacityNode = this.opacityNode ? float( this.opacityNode ) : materialOpacity;

        // By convention, a normal packed to RGB is in sRGB color space. Convert it to working color space.

        diffuseColor.assign( colorSpaceToWorking( vec4( directionToColor( normalView ), opacityNode ), SRGBColorSpace ) );

    }
