WorldBuilder
4 Tutorials - Volcano - Page 1: Getting Started
IThis
is a pretty simple project. It uses some of WorldBuilder 4' s
more familiar tools, but in a slightly different way.
Note
that this tutorial is designed to be used with the free downloadable
Demo version of WorldBuilder 4. Certain features such as file
and rendered image saving are disabled in this version. If
you would like to compare your work with the scene created in this
tutorial example *.awb files are available for download along with
this tutorial.
Let' s start by opening WorldBuilder 4. The default scene
includes the basics for creating our environment: a Camera, a Parallel
Light source, a Landscape and a Compound Sky element.
Note:
To speed up rendering, the AltoStratusClouds2 and SunDiskWithHalo1
components have been hidden. They can be ‘unhidden'
at any time by right-clicking on them in the Scene Tree.
Add
a Skeleton Line set from the Library. Choose volcano3 from
the skeletons group and drag it into the Scene Tree.

|
Render
the scene in the Camera Viewport, to observe how our Skeleton
Lines are deforming our landscape.
Note:
the camera and light angles in this tutorial is different
from the one in the default scene file. See the example
scene file volcano_tutorial.awb for precise camera
and light Location & Direction property coordinates.
Now
let' s fine-tune the geometry of the landscape.
|
|
For
Landscape0, use a Settings > Points value
of 1024.
Enable
Cast Shadow (so that our mighty Volcano throws a mighty
shadow) and Shielded Polygon Culling (so that WorldBuilder' s
rendering engine will ‘ignore' those parts of
the landscape terrain mesh which are not visible to the camera,
thereby saving render time).
Note:
The light source(s) in this tutorial use the Shadow Map feature.
For more information about Shadow Maps see the WorldBuilder
Basics tutorial.

Under
Landscape0' s Skin property, set Evolution
to 70; this will give our volcano a relatively smooth
slope angle.
Now
set Roughness to 93; this will keep the slope
surface itself from appearing too smooth and featureless.
|
|
Render
the scene again.
Our
volcano may look a little strange at this stage.
That's because we're not quite done with adjusting its geometry.
