ADOBE DIRECTOR BASICS
3D basics
3D and 2D views
A 3D camera displays all the models visible in its field of view. It can also display 2D overlays and backdrops. Overlays
appear in front of the visible models, backdrops appear behind all the models. For more details see “Overlays and
backdrops” on page 112.
Refreshing the camera view
Every camera has a colorBuffer property. This determines what color to show in areas that are not filled with models,
overlays or backdrops. You can set this background color for all cameras in the 3D cast member through the
Background color chip in the Property Inspector at the 3D Model tab.
When a camera refreshes its view of the world, the render process follows this order:
Fill view with background color
Show backdrops
Render visible models
Show overlays
To clear or not to clear at render
You can tell a camera not to clear the previous view with the background color. When the 3D sprite next refreshes its
view, it will render the models in their new position on top of the existing view. This can be exploited in different ways:
to create trails (if you use one camera), or to create a skybox effect (if you use multiple cameras).
To see an example of trails, download the movie Interpol.dir and launch it.
Setting a camera's colorBuffer.clearAtRender property to FALSE can create trails.
To see an example of a skybox, download the movie Skybox.dir, , and launch it. You can use the mouse and arrow keys,
and keys I, O, W and S to move the camera.
