tform_move - Geometric procedure

Creates a transformation


Description

Creates a translational transformation with optional scaling.

Syntax

tform_move(id, p1, p2, sx, sy, sz:attributes);

REF	id;
VECTOR	p1;
VECTOR	p2;
FLOAT	sx;
FLOAT	sy;
FLOAT	sz;

Principal parameters

id	- Local identity
p1	- Original position
p2	- Translated position and origin for optional scaling

Optional parameters

sx	- Scalefactor in X-direction, default = 1
sy	- Scalefactor in Y-direction, default = sx
sz	- Scalefactor in Z-direction, default = sy

Attributes

PEN	- Pen or colour number
LEVEL	- Level number
BLANK	- Visible(0) or invisible(1)

Example

tform_move(#1,vec(0,0,0),vec(100,0,0),1,1,5);

Creates a translation of 100 units in the X-direction with simultaneous scaling 5 times in Z. Scaling is performed with X=100 and Y=Z=0 as origin.
