Functions

BasicLightMapNode.setup(builder: any): void

Parameters:

  • builder any

Returns: void

Calls:

  • float (from ../tsl/TSLBase.js)
  • this.lightMapNode.mul

Internal Comments: 

// irradianceLightMap property is used in the indirectDiffuse() method of BasicLightingModel (x2)

Code 
setup( builder ) {

        // irradianceLightMap property is used in the indirectDiffuse() method of BasicLightingModel

        const RECIPROCAL_PI = float( 1 / Math.PI );

        builder.context.irradianceLightMap = this.lightMapNode.mul( RECIPROCAL_PI );

    }
