The plugin can be found in the folder: Viz Artist 3: Built Ins -> Container Plugins -> Maps.

The MapPyramid plugin is used to build a set of map layers for displaying an area in high resolution when zooming into a specific area. The maps are created as GeoImage (flat map) or Globe objects and placed under a low resolution map of the entire area for geographical referencing. The Map Tiler plugin is also used for managing Pyramid object maps when used in a scene.

Properties

images/download/attachments/29301748/plugincontainer_mappyramid_editor_scaled.png

  • Viz World Map Editor (WME) : will open the new WME

  • WME (Classic): will open the WME Classic Interface

  • Mode: Defines the maps mode. Available modes are Static and Dynamic.

    • Static: Enables the maps to be imported to Viz Artist’s image library and saved with the scene.

    • Dynamic: Enables the pyramid maps to be loaded from the cache and temporary folder. When the CWMClient receives a new map, the pyramid will be generated.

  • Map Style: Defines the map style to be used for the pyramid maps:

    • Source: Uses the top CWMClient container (Map Tiler) style selection when creating the pyramid maps.

    • Target: Uses the hop CWMClient style selection when creating the pyramid maps.

    • Split: Splits the pyramid layers style, based on image latitude and longitude size. If the image size is smaller then the threshold the target style will be used, if larger then the source style will be used. Additionally, it is possible to turn on the color correction option in Pyramid Control which will color correct the target image to match the source images. Set the Satellite Threshold (deg).

  • Max Pyramid Height: Defines the maximal number of maps that will be created in the pyramid. The optimal number of pyramid maps is calculated by the MapPyramid plugin. If the optimal number exceeds the Max Pyramid Height value, then the plugin will generate the maximal number defined.

  • Pyramid Factor: Calculates the number of maps required defining the size factor between the maps of the pyramid.

  • Pyramid Steps: Defines how the map coverage area grows from pyramid to pyramid:

    • Equal: The size factor will be based on map pyramid height, pyramid factor and the resolution difference between the base map and the final map. The actual number might be different than the pyramid factor. The number of levels might also be smaller than the max pyramid height

    • Constant: The value of the pyramid factor will be used as is, with the value of max pyramid height.

  • Create Hole: Will create a hole on each pyramid tile

  • Image Aspect: (Power of 2). Will calculate the closest power of 2 size, based on the selected image size of the CWMClient Plugin texture size. Target will use exactly the same size as the CWMClient Plugin texture size.

    Note: It is recommended to use this setting to improve performance.

  • Auto Hide Local Texture (Hide Lower Resolution): Defines whether the map created by the CWMClient plugin, located on the MapPyramid container, will be turned off when the texture resolution of that map is lower than the Globe or GeoImage map tiles resolution. If it is enabled (On), the maps with lower resolution will be turned off automatically by the MapPyramid plugin. If it is disabled (Off), the MapPyramid will not turn off the low resolution maps.

  • Apply Fade: Defines whether the maps used in the pyramid will use soft edges. Available options are Off, Target and Pyramid.

    • Off: No soft edges will be used. The transition between the maps will be visible (the maps will have sharp edges).

    • Target: Sets the last map (target) to have soft edges only.

    • Pyramid: Sets all maps in the pyramid to have soft edges.

  • Fade Range: When Apply Fade parameter is used, the Fade Range is used to set the fade level (the area of the image that the fade will be applied to).

  • Build Tiles: Triggers a rebuild of the pyramid maps.
