6. Placing Shapes in a Scene
When you create a geometry, it has a specified size, location, and orientation, as defined
in its own space. You place such a geometry
• In relationship to other shapes in the same scene.
• Into the coordinate system of the root node, known as world space.
This chapter describes how to perform each of those tasks.
The final transformation that affects the view of the user is that created with the camera.
Rotating the camera has an obvious affect on the view of the scene. To read more about
the camera transformation, see “Using a Camera to View a Scene” on page 98.
This chapter has the following sections:
•“Creating a Sense of Depth” on page 77.
•“Transforming Shapes to New Locations, Sizes, and Orientations” on page 79.
Creating a Sense of Depth
Geometries are layered by Cosmo 3D according to the order in which they are rendered.
For example, the first geometry rendered is usually covered by the second geometry if
they overlap.
