Functions

cloneUniforms(src: any): {}

Parameters:

• src any

Returns: {}

Calls:

• console.warn

• property.slice

Code

export function cloneUniforms( src ) {

    const dst = {};

    for ( const u in src ) {

        dst[ u ] = {};

        for ( const p in src[ u ] ) {

            const property = src[ u ][ p ];

            if ( property && ( property.isColor ||
                property.isMatrix3 || property.isMatrix4 ||
                property.isVector2 || property.isVector3 || property.isVector4 ||
                property.isTexture || property.isQuaternion ) ) {

                if ( property.isRenderTargetTexture ) {

                    console.warn( 'UniformsUtils: Textures of render targets cannot be cloned via cloneUniforms() or mergeUniforms().' );
