Each model is composed of different types
of elements which fall into one of the following groups:
|
| |
 |
Objects |
| |
The object is the main element of the model. You can have
many Object elements in the model but it is not possible to
directly associate colors and materials to an object.
|
| |
|
|
|
Instance Objects |
| |
Instance Objects are contained in the space of the object.
They are references to other objects, each with its own
position, orientation, scale, color and material. You can have
many Instance Object elements in the model. An instance object
is always associated with an object.
|
| |
|
|
|
Cameras |
| |
Several Camera elements can be defined in the model, each
with its own properties. Any Camera element can be associated
with the View and the animations.
|
| |
|
|
|
Colors |
| |
Colors are based on RGB values. Several Color elements can be
present in the model, each with its own properties. Color
elements can be associated with background and materials.
|
| |
|
|
|
Pictures |
| |
Pictures are bitmap images useful to create the background or
different kind of materials such as wood, stone and fabric.
Images can be included in the model or can be external links to
a file containing the bitmap. Picture elements can be associated
with materials and background. A model can contain several
Picture elements.
|
| |
|
|
|
Materials |
| |
Materials make the scene more realistic, they describe how an
object reflects and transmits light: image mapping, reflections,
transparencies and other effects are applied. The Material
elements are associated with instance objects. A model can
contain several Material elements.
|
| |
|
|
|
Background |
| |
The background is displayed in the View. Only one Background
element is contained in the model.
|
| |
|
|
|
Animation |
| |
Animation is a sequence of key points set in time: each key
point causes a series of transformations of some elements over
time, for example to create animations of the movement of the
camera or of the moving instance objects. The animation is
associated with camera and instance objects.

|
|
|
Work Lights |
| |
Work Lights are parallel light sources used in solid and
non-realistic rendering mode, and they are constantly affecting
the surfaces of the shapes. A model can contain several Work
Light elements.
|
| |
|
|
|
Realistic Lights |
| |
Realistic Lights are parallel light sources equivalent to the
sun used in realistic rendering mode, and they are constantly
affecting the surface of the shapes. A model can contain several
Realistic Light elements.
|
| |
|
|
|
Lights Source |
| |
Light Sources simulate real light like the bulb of a swinging
lamp used in realistic rendering mode. The model can contain
several Light Source elements. The Light Source element is
associated with an instance object.
