ADOBE DIRECTOR BASICS
3D: Controlling appearance
-- Lingo
v3DSprite = sprite("3D")
v3DMember = v3DSprite.member
vCamera = v3DMember.newCamera("Top Down")
vCamera.projectionAngle = 45.0
vCamera.worldPosition = vector(0, 250, 1)
vCamera.pointAt(0, 0, 0)
// JavaScript
v3DSprite = sprite("3D");
v3DMember = v3DSprite.member;
vCamera = v3DMember.newCamera("Top Down");
vCamera.projectionAngle = 45.0;
vCamera.worldPosition = vector(0, 250, 10);
vCamera.pointAt(0, 0, 0);
Rendering a secondary camera in the 3D sprite
The view from the new camera is automatically rendered to the 3D sprite. You need to provide two additional
instructions. Here are the scripting terms you need to use: sprite3d.addCamera() and camera.rect.
The following example creates an inset at the top left corner of sprite(“3D”) to show the output of the new camera
(“Top Down”):
-- Lingo
v3DSprite = sprite("3D")
vCamera = v3DSprite.member.camera("Top Down")
v3DSprite.addCamera(vCamera)
vCamera.rect = rect(0, 0, 160, 120)
// JavaScript
v3DSprite = sprite("3D");
vCamera = v3DSprite.member.getPropRef("camera", 2);
v3DSprite.addCamera(vCamera);
vCamera.rect = rect(0, 0, 160, 120);
All sprites that display the same 3D cast member display the same secondary camera views. It is not advisable to use
the same camera as the main view for one sprite and as a secondary camera for another sprite. The dimensions of the
sprite where the camera is used for the main view affects the camera.rect for the secondary view in the other sprite. The
two views will have the same dimensions. You can set the rect of the primary camera of a 3D sprite, but you may get
unexpected results if you make the dimensions of the camera.rect smaller than the dimensions of the sprite.
Deleting a secondary camera view
To remove a camera that you have added to a 3D sprite, you can use sprite3d.deleteCamera(). This will remove the
secondary camera view from all sprites that display the same 3D cast member. It will not delete the camera from the
3D cast member itself.
Color buffer
Every camera has a colorBuffer property. You cannot access this directly, but you can get and set the values of its two
properties:
camera.colorBuffer.clearValue
camera.colorBuffer.clearAtRender
The clearValue property defines a fill color and clearAtRender determines whether that color is used to fill in any blank
spaces behind visible models.
