2. Primitives

Simple 3D models can be created inside Nemo, it is not necessary to use a 3D modelling

application for this task. These simple models are collectively called primitives. The simplest

primitive, Rectangle, has several special functions, and special mention should be made also of

piechart, which could be a big help in making circular diagrams.

They have the common properties identical with those of the Text Object.

Special properties:

● primitive Type: the type of the Primitive. See the list for yourself, it should be self-

explanatory.

● slices and stacks: it indicates the number of polygons (usually triangles or quads) used

in creating the primitive. The influence of these values can be best appreciated with a

sphere primitive. Even with a simple rectangle the number of polygons can make a

difference. In OpenGl, the greater the number of polygons, the more precise the effect of

lighting (if you use vertex lighting, of course, in case of per pixel calculations, it does not

matter).

● two sided, if the backside of the rectangle is also required.

● fit to screen: in this case - no matter what transformations are set for the rectangle, it will

always perfectly fill the screen. Only Translate Z has any effect, as it defines the distance
