In the 3D panel of the Preferences dialog box—Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS)— you can determine whether the 3D toolbar and Model Tree are displayed by default. You can also specify a default renderer and determine whether animations are allowed.
Specifies the rendering engine used to affect both performance and quality, so it’s important to select the appropriate renderer. Depending on your system, you may want to change your render engine. For Windows XP, you may be able to select DirectX 8, DirectX 9, or Software. For Mac OS 10.3 or later, you can select OpenGL or Software. If you select a DirectX or OpenGL option, all rendering takes place using the graphics chip on the video card. If Software is selected, rendering may take more time, but the performance may be more consistent with that of the model in its originating application.
Determines whether the Model Tree is displayed when the 3D model is activated. Choose Use Annotation’s Setting to use whichever setting the author used when adding the 3D model to the PDF document.
Determines whether the 3D toolbar is shown or hidden when a 3D model is activated. Choose Use Annotation’s Setting to use whichever setting the author used when adding the 3D model to the PDF document.
Displays a button on the 3D model that lets you hide or display the 3D toolbar.
Some model parts have two sides. To save time and space, you can deselect this option to render only the side facing the user. If the user looks inside a part rendered with only one side, the back side would be invisible.
Some 3D models include animations enabled by JavaScript. Deselect this option to prevent 3D animation.
Lets the user select and highlight parts of the 3D model using the Hand Tool. If this option is not selected, use the Object Data Tool (Tools > Object Data > Object Data Tool) to select the object.
Selecting this option places the manipulation and navigation tools under the Rotate Tool, thereby shortening the 3D toolbar.
