Tab
), scale it 3.5 times bigger (press
S
, digit
3.5
, and hit
Enter
) and go
out of edit mode (press
Tab
). Now, move the plane one Blender unit down
(press
G
, then
Z
, digit
-1
, and then hit
Enter
).
4. Go to the little icon (
Viewport Shading
) showing a sphere in the bottom
bar of the 3D view and click on it. A menu showing different options
appears (
Bounding Box
,
Wireframe
,
Solid
,
Texture
,
Material
, and
Rendered
). Select
Rendered
from the top of the list and watch your cube
being rendered in real time in the 3D viewport.
5. Now, you can rotate or/and translate the view or the cube itself and the

7. Select

window under the

panel on the right-

9. Under the
Nodes
tab, click on
Use Nodes
to activate a node system for
the selected light in the scene; this node system is made by an
Emission
closure connected to a
Lamp Output
node.
10. Go to the
Strength
item, which is set to
100.000
by default, and start to
increase the value—as the intensity of the Lamp increases, you can see
the cube and the plane rendered in the viewport getting more and more
bright, as shown in the following screenshot:
How to do it...
We just prepared the scene and had a first look at one of the more appreciated fea-
tures of Cycles: the real-time rendered preview. Now let's start with the object's ma-
terials:
