Functions

Camera.copy(source: any, recursive: any): this

Parameters:

• source any
• recursive any

Returns: this

Calls:

• super.copy
• this.matrixWorldInverse.copy
• this.projectionMatrix.copy
• this.projectionMatrixInverse.copy

Code

copy( source, recursive ) {

        super.copy( source, recursive );

        this.matrixWorldInverse.copy( source.matrixWorldInverse );

        this.projectionMatrix.copy( source.projectionMatrix );
        this.projectionMatrixInverse.copy( source.projectionMatrixInverse );

        return this;

    }

Camera.getWorldDirection(target: Vector3): Vector3

JSDoc:

/**
     * Returns a vector representing the ("look") direction of the 3D object in world space.
     *
     * This method is overwritten since cameras have a different forward vector compared to other
     * 3D objects. A camera looks down its local, negative z-axis by default.
     *
     * @param {Vector3} target - The target vector the result is stored to.
     * @return {Vector3} The 3D object's direction in world space.
     */

Parameters:

• target Vector3

Returns: Vector3

Calls:

• super.getWorldDirection( target ).negate

Code

getWorldDirection( target ) {

        return super.getWorldDirection( target ).negate();

    }

Camera.updateMatrixWorld(force: any): void

Parameters:

• force any

Returns: void

Calls:

• super.updateMatrixWorld
• this.matrixWorldInverse.copy( this.matrixWorld ).invert

Code

updateMatrixWorld( force ) {

        super.updateMatrixWorld( force );
