3D Applet Documentation
The basic concept of this applet is that three points, that are well defined, are assembled to a triangle and thus form a polygone with a surface. It offers simple functions to define the junctions between several points as well as high-level functions that are predefined objects that consist of numerous polygones.
The idea is that polygones are grouped in objects like cubes, spheres etc.
The objects themselves can be grouped in containing objects again.
Thus, the applet allows a simple manipulation of complex objects.
Documentation of the functions:
PUBLISH ON THE WEBSITE will upload a file that you have created and publish it on the gallery of the site
the EXPORT functions convert the files to POV-Ray format (a rendering tool) or VRML
as this applet offers you the possibility to achieve real 3D effects with red/green 3D-glasses you will have to CALIBRATE it to your glasses. The trick is that the object will be showed in two pictures. Your glasses should have the effect that you only see one of the pictures on each eye. thus it is important to calibrate in a way that you do not see the edge between white and the color on one side while having a visible contrast between the color and white on the other side.
Just try it, it's easier than it might sound!
3D PREVIEW will show the object with the described 3D effect
NORMAL PREVIEW will show you a rendered image (with light effects) of the object
most of the functions in EDIT are as you expect them to be from other programs
the LINKING functions concern the links between the points
SNAP will align the selected points the lines of the grid in the development environment
COLORIZE should be evident
the object that can be ADDED should be know
a VERTEX is just another (mathematical) word for one of these points
LIGHT is a light source that will give you the desired light effects depending on where you place it
the OBJECT functions should be comprehensive too, the only thing you have to keep in mind is that objects can be part of other objects, that is why you can add one to another or remove it again
the SELECTED object is the one you can work on by using the buttons below
the SELECT button does basically the same as the mentioned menu item, however it allow you select items that are not an object (vertexes, lines etc.), and it is much easier to select an object by using the menu item because this offers you a list of all the objects
the STRETCH buttons scale the object in one, two or three dimensions
each of the three grids represent the view from one axis (x, y or z)
the fourth square is reserved for previews
the arrows on the grids will scroll them
+ and - will zoom in and out
however, note that you do not change neither the objects size by zooming nor its position by scrolling
It might seem to have too many complicated functions but we are sure that you will get used to it very quickly.
If you keep in mind that one view is from the front, the other from the side and the last from above you shouldn't have any problems with it.
