INTRODUCTION
The following tutorial illustrates some of the capabilities of haptic
technologies. The Free Form modeling system software allows the user to use the sense of touch for creating three dimensional models on the computer. This is an intuitive and expressive tool that is similar to working with clay or foam materials. The primary advantage of this tool is that it allows the user to test and compare multiple design proposals for complex surfaces without the waste or expense of materials.
Basics: WORKSPACE
This is the virtual sculpting environment that begins each work session in Free Form Software. The white square on the screen represents a block of virtual clay. This configuration is the default setting for all sculpting activity.
Basics: EMPTY MODEL SPACE
Free Form Software also allows you begin with an empty modeling space. Choose File, New from the pull-down menu to obtain the “Create Model Screen.”
The result of selecting this option will be a completely empty work space.
Material Options: EMPTY MODEL SPACE
To add clay: First, From the Free Form Tool Menu, select the desired tool.
This allows more flexibility in sizing the digital clay material more closely to the match your specific design parameters.
Basics: MOUSE FUNCTIONS
The left mouse key allows you to view the object from many angles. You may also adjust or save specific views by selecting the view command from the main toolbar menu.
Material Options: CLAY COARSENESS
Free Form Software also allows you adjust the “coarseness” of the digital clay. This option adjusts the grain size of the material and maximum tool size available.
In general it is best to begin with rough shape option. The other options (Refine Shape, Add Detail, Add Free Detail and Custom are best used for finishing work.)
STREAM TOOL
This tool allows the addition of
digital clay material in streams
that are dictated by the shape
and size of the tool selected.
It is best used for small additions
of material and offers a unique
flexibility not found in stone carving, for example. Although
the blobs are so irregular that once they are added, they must be shaped considerably, in most cases.
