The next step for your carreer at SGAG is to be an SGAG Constructor. You will be something like an engineer, an arquitect. You will create customized galleries using the "SGAG objects" (also called "blocks").

SGAG uses the traditional Cartesian Coordinate System where we have 3 axises: X, Y and Z.

Any point in the space is defined by 3 numbers. The values for x, y and z.

Whe can call the region where Y=0: Floor

We have created inside the SGAG environments, for help the SGAG Constructors, a "Grid" that shows the points of the Floor. You will use it for the exercices of the training we are beginnig here (and for the "real life", creating SGAG galleries).

So, your first task is to create a new blog at Blogger having the "SGAG Template".

At this template change the parameters DEFAULTGALLERY and GRID. Look:

...
////////////////////////////////////////////////
////AREA FOR INSTALLERS & CONSTRUCTORS & WIZARDS
////////////////////////////////////////////////
'DEFAULTGALLERY="no";'+
//Change to "no" if you are defining your gallery
'GRID="yes";'+
////////////////OBJECTS HERE:
 
 
///////////////////////////////////////////////////
////////END OF SGAG SCRIPT AREA
//////////////////////////////////////////////////
...

Opening the SGAG space you will see the grid in the floor. The avatar lands at the point where X=0, Y=0 and Z=0. He looks in the North direction .

A Cartesian Coordinate System has 4 "quadrants":

To facilitate your work you need to save (right-click) this image at any place of your hard disk

It is the Floor of the 2nd Quadrant.

A point at this floor will have a value of X that will be positive. And a value of Z that will be negative.

IMPORTANT: The dimensions in SGAG are defined in centimeters.

This quadrant has 5000 x 5000 centimeters.

OK. Opening our figure of the 2nd Quadrant Floor at Windows Paint (or Photoshop etc.) you need to print some copies of it on paper. Like we said, now you will be an engineer, an arquitect. And engineers, before to construct anything, use to design it over a blueprint.

Our initial exercice will be very easy:

Exercice 0: Design a point in the position having X = 2000 and Z = - 4000.

Try to do it now and before to go to the next lesson, look the correct result here.
