Creating the first scene

Creating a sphere

The scene is now empty. No object, no lamp is in. Select the front view. This will be the view where you will work.

Now will add an object in the scene. Move the cursor in a zone of view window far from the camera. Click with the right button
of the mouse. A menu will pop up. This allow to create a new object in that position.


 
 

Then the scene will be:


 
 

Create a lamp

Now you should add a light source in the scene if you want to render it. It is simple like to create a sphere. Create a point lamp
like in the picture above.


 

The pointlamp object look like a sphere but they are quite different; the pointlamp is invisible but allows to see the other objects.
To see what type of an object is, select him, then on the status bar you will see the name of the object and the type.
 
 

Create the image

Now you can render the image. Use Command "Action|Create image". The views will disappear and the program will start to
render. If you have a true color display you will see the correct image, else you will see an approximate image. The status bar
will show the line under rendering and a guess of the time remaining.

The final image will be:
 

You can return to the wireframe views using command "Window|All views".

The image size is 100x100 pixels. If you think it is too small you can change it. To do it, select the camera then click right button
on the camera.

This action will show a menu that allow to modify the object. This menu is the same for every object except for the last item
"Special", which may be different from type to type. For camera use "Special|General".

"dimx" is the horizontal dimension ( in pixels ), "dimy" is the vertical dimension ( in pixels ), "focald" the focal distance (the
distance from PRP to VRP ), "high" is the dimension of the window on the projection plain.


 

Try to change:

dimx from 100 to 320

dimy from 100 to 200

high from 2 to 0.5

Now render again the scene. The output will be bigger.
