Subject: Tess 1.05 PPC - Symmetric Drawing Program
With Tess, you can quickly create attractive symmetric planar
illustrations. While you draw, Tess will automatically maintain the
symmetry group you have chosen; 11 rosette, all 7 frieze, and all 17
wallpaper groups are included. Illustrations may be saved using Tess1
own cross-platform format or printed out using your own ink-jet or
laser printer. Tess is shareware; unregistered copies are
fully-functional, but are for evaluation purposes only until
registered. Tess has an English and a Korean interface
Recent changes: (changes since 1.04)
* A Korean interface is now available; the translation was performed by
the Mathlove company of Korea.
* Using the preferences, you can now choose the system of notation used
to name symmetry groups: Fejes Toth notation, short crystallographic,
full crystallographic, and orbifold notation are available.
* A fundamental region or a lattice cell for the current symmetry group
can now be shown by selecting either "Show a Fundamental Region" or
"Show a Lattice Cell" in the "View" menu. When a lattice cell is
shown, a thick line will display one axis of the lattice cell so that
primitive and centered cells can be distinguished. These new display
aides can help you understand crystallographic and orbifold notation.
* Guides for mathematical terminology and symmetry group notation have
been added: select "Terminology" or "Symmetry Group Notation" in
the help menu to open a guide.
* The amount of rounding or smoothing applied to the corners of objects
can now be controlled by entering a maximum corner radius. This radius,
specified in pixels or as a percentage of the distance between adjacent
control points, controls the curvature of the circular or elliptical
arcs used.
* "Smooth" and "Sharpen" menu items have been added to the
"Object" menu; selecting these items will increase and decrease the
selected objects' maximum corner radii.
* You can now enable and disable the stroking and filling of already
created objects with the newly available fill and / or stroke buttons in
the tool window.
