Functions

checkRayDirectionAgainstReferenceVector(rayDirection: any, refVector: any, assert: any): void

Parameters:

  • rayDirection any

    assert.ok( refVector.x - rayDirection.x <= Number.EPSILON && refVector.y - rayDirection.y <= Number.EPSILON && refVector.z - rayDirection.z <= Number.EPSILON, 'camera is pointing to' +
        ' the same direction as expected' );

}

getRaycaster(): Raycaster

Returns: Raycaster
