Functions

depthCompare(uv: any, compare: any): TextureNode

Parameters:

• uv any
• compare any

Returns: TextureNode

Calls:

• texture (from ../accessors/TextureNode.js)
• depth.depth
• depth.compare

Code

( uv, compare ) => {

        let depth = texture( depthTexture, uv );

        if ( depthTexture.isArrayTexture ) {

            depth = depth.depth( depthLayer );

        }

        return depth.compare( compare );

    }

depthCompare(uv: any, compare: any): TextureNode

Parameters:

• uv any
• compare any

Returns: TextureNode

Calls:

• texture (from ../accessors/TextureNode.js)
• depth.depth
• depth.compare

Code

( uv, compare ) => {

        let depth = texture( depthTexture, uv );

        if ( depthTexture.isArrayTexture ) {

            depth = depth.depth( depthLayer );

        }

        return depth.compare( compare );

    }

linearShadowDistance(light: any): void

Parameters:

• light any

Returns: void

Calls:

• reference( 'near', 'float', camera ).setGroup
• reference( 'far', 'float', camera ).setGroup
• objectPosition (from ../accessors/Object3DNode.js)
• linearDistance

Code

( light ) => {

    const camera = light.shadow.camera;

    const nearDistance = reference( 'near', 'float', camera ).setGroup( renderGroup );
    const farDistance = reference( 'far', 'float', camera ).setGroup( renderGroup );

    const referencePosition = objectPosition( light );

    return linearDistance( referencePosition, nearDistance, farDistance );

}

getShadowMaterial(light: Light): NodeMaterial

Parameters:

• light Light

Returns: NodeMaterial

Calls:

• shadowMaterialLib.get
• linearShadowDistance
• vec4 (from ../tsl/TSLBase.js)
• shadowMaterialLib.set

Code

( light ) => {

    let material = shadowMaterialLib.get( light );

    if ( material === undefined ) {

        const depthNode = light.isPointLight ? linearShadowDistance( light ) : null;

        material = new NodeMaterial();
        material.colorNode = vec4( 0, 0, 0, 1 );
        material.depthNode = depthNode;
        material.isShadowPassMaterial = true; // Use to avoid other overrideMaterial override material.colorNode unintentionally when using material.shadowNode
        material.name = 'ShadowMaterial';
        material.fog = false;

        shadowMaterialLib.set( light, material );

    }

    return material;

}
