Volume Heat Map

Notes:

Visibility is line-of-sight, adding primitives to the scene will block visibility.  

It's important to note that without a blocking element, the visibility represents ideal conditions with no occlusions.  

Toggling the Volume Heat Map

When cameras are added to the volume you can enable the heat map view of camera visibility by pressing the Volume Heat Map button, from the default selection inspector.

To disable the heat map view press the Turn Off button in the heat map settings. 

Marker distance

The marker listed in the volume heat map tool panel affects the maximum distance cameras use to affect the Volume heat map. This distance is also reflected in the displayed frustums of the cameras. 

You can change the associated marker size by pressing the marker size button and selecting a new [Marker Type/Size] from the list.

Visible range

The range slider controls the displayed visibility in the Volume Heat map.

Green = 4+ cameras with visibility

Yellow = 3 cameras with visibility

Orange = 2 cameras with visibility

Red = 1 camera with visibility

Select the No Visibility button to see the area in the volume where no cameras have visibility.

Interactive mode

When Interactive is checked, the app will constantly recalculate the volume heat map. You can press Refresh to selectively recalculate when it's disabled.  

In heavy scenes or on certain devices it is advised to disable Interactive to improve performance and/or battery life.  

Interactive is disabled by default when there is an occluding object in the scene.
