swf_ortho

Name

swf_ortho — Define 3D co-ordinate system

Synopsis

void swf_ortho(xmin, xmax, ymin, ymax, zmin, zmax);
double xmin: X-axis minimum
double xmax: X-axis maximum
double ymin: Y-axis minimum
double ymax: Y-axis maximum
double zmin: Z-axis minimum
double zmax: Z-axis maximum

Returns

Void

Description

Creates a co-ordinate system inside the SWF background for manipulation and transformation of objects. Normally the X and Y axis starts from the bottom left corner. Using swf_ortho() the co-ordinate system can be redefined indpedent of where to co-ordinates usually start and the dimensions of the file.

In the example below, a SWF file 200x200 pixels is adjusted to have a co-ordinate system of 100x100x100 pixels with an origin startting in the middle of the square. This means that the displayed text is displayed at 0,0,0, or at the centre.
