MOI – Moment Of Inspiration
Two worlds
There are two main types of creation in 3D. The first family is the family polygonal, we all know and use regularly. A model is described in terms of faces, edges and vertices. Mesh products provide great flexibility because you can change the position of individual facets, orientation or size.
The second family is the family of NURBS, much less familiar to users of polygonal. This family operates from curves and surfaces generated mathematically. There is no facet, but a parametric description of surfaces and solids. Software called “CAD” in the lion’s share in areas related to design or creation of prototypes. Indeed, they allow feats that are unable to perform the software polygonal: smooth curves without faceting, Boolean and leave perfect, rapid creation linked to historical construction.
The problem is that these two families are not compatible. Their philosophies are very different from description of the models make the conversion from one type of model to another is very difficult to achieve. In general, CAD programs offer export a triangulated polygonal chaotic, inadequate, and no UV coordinates. As for processing NURBS to polygons, it is simply not used (except perhaps that was the pioneer Amapi Pro).
Why such a lack of communication? Simply because our two families operate two very distinct areas of 3D. When working with a software like Rhino or Solidworks, export polygon is almost incidental (except perhaps in the field of stereolithography) because software is often in communication directly or machines with prototyping.
Therefore we lack, even today, allowing software to design NURBS objects intended to be subsequently exported polygonal. This is unfortunate, because no program can not currently compete with NURBS with respect to the production of mechanical or design models.

The strength and originality of MOI is to bring in fans of polygons and a simple alternative to the effective creation of models. This software is more than a breath of fresh air, a true bridge between two opposing worlds.

The interface
It has been so for quite some time, a program was born, who wanted to propose to the designers NURBS democratically. The team hired an intern, which provides an easy interface and file format, now the time ultra-popular format 3DM. This young intern named Michael Gibson, and the full program …
Rhino. Suffice it to say that Mr. Gibson is not a beginner, and it shows the willingness to reach each of the power and flexibility of NURBS, we tend to listen.
The interface I is a model of simplicity. After the printing of “toy”, it is compact and very fast to absorb. Each group of functions is stored in a dedicated box: curves, sound, editing, construction … Click on a generic function: immediately rearrange buttons and sub-functions appear. At the top of the screen then come the various options and the modus operandi of the function selected. Simple, clear, effective.
