Action: Creates a transform to mirror an object through an axis.

Filename: kern/kern_scm/tran_scm.cxx

Syntax: (transform:reflection plane-position


plane-direction)

Arg Types: plane-position position

plane-direction gvector

Returns: transform


plane-position specifies the location to mirror an object.


plane-direction specifies the normal of the mirror in the plane.

Example: ; transform:reflection

; Define a working coordinate system.

(define wcs1


(wcs (position 0 0 0) (gvector 1 0 0)


(gvector 0 1 0)))

;; wcs1

; Set a color for the wcs.

(entity:set-color wcs1 6)

;; ()

; Create a solid block.

(define block1


(solid:block (position 0 0 0)


(position 5 10 15)))

;; block1

; OUTPUT Original


; Create a transform and then create its reflection.

(define transform1


(transform:reflection


(position 0 0 0) (gvector -1 0 0)))

;; transform1

; Apply the transform to reflect the block.

(define transform


(entity:transform block1 transform1))

;; transform

; OUTPUT Result
