Functions¶
SplitNode.getVectorLength(): number¶
JSDoc:
/**
* Returns the vector length which is computed based on the requested components.
*
* @return {number} The vector length.
*/
Returns: number
Calls:
Math.maxvectorComponents.indexOf
Code
SplitNode.getComponentType(builder: NodeBuilder): string¶
JSDoc:
/**
* Returns the component type of the node's type.
*
* @param {NodeBuilder} builder - The current node builder.
* @return {string} The component type.
*/
Parameters:
builderNodeBuilder
Returns: string
Calls:
builder.getComponentTypethis.node.getNodeType
Code
SplitNode.getNodeType(builder: NodeBuilder): string¶
JSDoc:
/**
* This method is overwritten since the node type is inferred from requested components.
*
* @param {NodeBuilder} builder - The current node builder.
* @return {string} The node type.
*/
Parameters:
builderNodeBuilder
Returns: string
Calls:
builder.getTypeFromLengththis.getComponentType
Code
SplitNode.generate(builder: any, output: any): any¶
Parameters:
builderanyoutputany
Returns: any
Calls:
builder.getTypeLengthnode.getNodeTypethis.getVectorLengthbuilder.getTypeFromLengththis.getComponentTypenode.build_stringVectorComponents.slicebuilder.formatthis.getNodeType
Internal Comments:
// needed expand the input node (x3)
// unnecessary swizzle (x3)
// ignore .components if .node returns float/integer (x3)
Code
generate( builder, output ) {
const node = this.node;
const nodeTypeLength = builder.getTypeLength( node.getNodeType( builder ) );
let snippet = null;
if ( nodeTypeLength > 1 ) {
let type = null;
const componentsLength = this.getVectorLength();
if ( componentsLength >= nodeTypeLength ) {
// needed expand the input node
type = builder.getTypeFromLength( this.getVectorLength(), this.getComponentType( builder ) );
}
const nodeSnippet = node.build( builder, type );
if ( this.components.length === nodeTypeLength && this.components === _stringVectorComponents.slice( 0, this.components.length ) ) {
// unnecessary swizzle
snippet = builder.format( nodeSnippet, type, output );
} else {
snippet = builder.format( `${nodeSnippet}.${this.components}`, this.getNodeType( builder ), output );
}
} else {
// ignore .components if .node returns float/integer
