The Specifier

The Specifier uses an approach that is far simpler than tools that rely on NURBS or tesselated-mesh based surface representations.
None of these tools use a grid in the specification or editing of 3D surfaces.
The are all based on the cartesian coordinate system, and the cartesian grid does not help in specifying or editing a 3D surface.
The Specifier's use of a hexagonal-grid makes the editing of 3D surfaces easy.
It is easy to specify angle or curves or surfaces on a hexagional grid.
The Specifier uses this fact to develop a hexagonal geometry modeler.

In addition,
- The Specifier uses InterUnit-UI, instead of WIMP, which makes it far simpler to use.
InterUnit-UI is a new design paradigm that has far better ergonomics than WIMP.
- Most existing tools are not that simple to use (they all use WIMP).
Shapr3D is a recent tool that has been specially designed for ease of use.
- The Specifier is being designed in sync with the design of a bicycle-trailer prototype.
Hence it's design is use-centric and domain relevant.
This also makes the design a lot simpler, since it starts with a narrow target.
- It includes the ability to do some ergonomic modeling of the user of the design.
- Since The Specifier uses a hexagonal grid as an underlying graphic design basis.
This makes its computational complexity a lot lower.
It is also designed with a minimal feature-set and resource usage approach,
since it is an introductory tool.
It does not have to rely on 3D hardware acceleration.
It will be very responsive on average PC hardware as a native app.
It does not have any server side execution components (like cloud based tools).

Most existing tools are either native, requiring workstation class processors,
or cloud-based, implying browser and internet-bandwidth constraints.
