3D Preview

In order to bring up 3D Preview, do the following:

  1. Right click on the 2D map.
  2. Select Show 3D Preview Here.
  3. A 3D Preview window will appear with a visualization of your data.

Hint

The 03000007 icon will also open the 3D Preview window.

  1. Right click on the 2D map.
  2. Select Show 3D Preview Here.
  3. A 3D Preview window will appear with a visualization of your data.

The position of the preview’s eye point is indicated as a wedge-shaped overlay on the 2D Map. It follows the preview to help identify where it is located. All project contents are used to generate the 3D visualization.

Users are able to quickly reposition the 3D preview camera by repeating the above steps.

2D Map Follows 3D Preview

To ensure that the 2D map reflects what is being seen in the 3D preview, be sure to use the Follow On Map feature. In this mode, the 2D Map will be updated periodically with the 3D Preview’s view position.

  1. In the 3D Preview window, right click.
  2. Select Map follows preview.

Hint

There is a short timeout that is reset any time motion is performed in the 3D Preview, so the map will not update until the 3D navigation has settled for 5 seconds to prevent excessive redraw behavior as the user navigates.

3D Preview Follows 2D Map

To ensure that the 2D map reflects what is being seen in the 3D preview, be sure to use the Follow On Map feature. In this mode, the 2D Map will be updated periodically with the 3D Preview’s view position.

To ensure that the 3D preview window reflects the movement within the 2D map, be sure to enable the Map follows preview feature. In this mode, the 3D preview view will follow as the user navigates the 2D map.

  1. In the 3D Preview window, right click.
  2. Select Preview follows map.

3D Preview Properties

The Preview Properties dialog allows the user to configure the behavior of the 3D Preview. While some changes can be seen immediately, the 3D Preview should be closed and reopened for all options to take effect.

To open the Preview Properties dialog, do the following.

  1. On the main menu, click Tools.
  2. Select Preview Properties.

Warning

Setting any of the following options too high may impact performance.

There are multiple Preview Property options.

  • Tiles per side: This number represents how many layers of tiles will surround the tile that the user is currently directly over. For example, setting this to 0 would only display a single tile. Setting this to 1 would add a single layer of tiles around the current tile for a total of 9 tiles in view. Setting this to 2 would add two layers for a total of 25 tiles in view, etc.
  • Number of posts: This number represents the resolution of a single tile’s geometry. Setting this to 256 would make the tile’s geometry a 256 x 256 grid. At 512, the tile’s geometry would be 512 x 512. To appreciate this effect, the user can press Tab to view a wireframe model of the tile and see the number of posts increase at higher resolutions and decrease at lower resolutions.
  • Image raster size: This number represents the resolution of a single tile’s imagery texture.
  • Tile level: This number controls the geographic size of tiles in the 3D Preview. A smaller number means larger tiles.
  • Restore Defaults: Sets the above options to their default values.
