important - change to AC3D file format

Andy · 12th August 2003, 09:50 AM

The next release increments the file format version and makes it 'c'.

This means that the first line of a new .ac file will change from "AC3Db" to AC3Dc". Older files are still compatible.

Objects now have an (optional) crease angle attribute e.g.

Code:

crease 45.0

This indicates that if the angles between two joined surfaces is more than 45 degrees, the edges between the surfaces will be drawn with a crease.

Valid crease angles are 0.0 to 180.0 degrees.

Setting a surface to flat-shaded forces it always to be drawn flat.

The default crease-angle in AC3D is currently 45 degrees.

Comments welcome.
