i guess you are using 03-camera.pd in Bewegungsmelder. The point is that
the students realize it is 3d. use [rectangle -4 3] to flip the
rectangle and look at it from the other side - thus the pixels textured
on it are in reverse order. m.
This particular trick would work even if [rectangle] were part of a 2D
toolkit. But otherwise, it's true that it's a good trick. It takes less
CPU than [pix_flip].
There are two ways to flip coordinates of a 2D thing : reflexion in 2D,
such as [scaleXYZ -1 1 1] or [scaleXYZ 1 -1 1] or rotation in 3D, such as
[rotateXYZ 180 0 0] or [rotateXYZ 0 180 0]. Picking the size of a
rectangle is the same as $1 $2 of scaleXYZ.
