Detailed Description
Visible and non-visible areas are determined for an area defined by an observer location, horizontal and vertical view angles, and a minimum/maximum distance range. These properties define a frustum (3D solid) inside of which visibility is calculated.
The minimum distance allows you to exclude obstacles close to the observer (the corner of a building, for example). Since terrain and other obstacles between the observer and the specified minimum distance are completely excluded from the analysis, this value should be relatively small.
Visibility is not evaluated beyond the maximum distance specified. This can be used to model factors that restrict the visible distance.
Note: You cannot declare or create a component of this type in QML code.
Property Documentation
Whether the Viewshed frustum outline is visible.
The frustum outline visibility can be controlled for individual Viewsheds.
Signal Documentation
Emitted when the frustumOutlineVisible property changes.
Note: The corresponding handler is onFrustumOutlineVisibleChanged.
Emitted when the horizontalAngle property changes.
Note: The corresponding handler is onHorizontalAngleChanged.
Emitted when the maxDistance property changes.
Note: The corresponding handler is onMaxDistanceChanged.
Emitted when the minDistance property changes.
Note: The corresponding handler is onMinDistanceChanged.
Emitted when the verticalAngle property changes.
Note: The corresponding handler is onVerticalAngleChanged.
Method Documentation
color frustumOutlineColor() |
Returns the color used to render the frustum outline.
The frustum (3D solid) within which visibility is evaluated can be symbolized with a specified outline color.
This is a global setting and applies to all viewsheds within the application.
See also setFrustumOutlineColor().
color obstructedColor() |
Returns the color with which non-visible areas of the viewshed will be rendered.
Areas of the scene view that are not visible from the observer location and within the frustum defined for the viewshed analysis will be rendered using the specified color.
This is a global setting and applies to all viewsheds within the application.
See also setObstructedColor().
void setFrustumOutlineColor(color frustumOutlineColor) |
Sets the color used to render the frustum outline to frustumOutlineColor.
The frustum (3D solid) within which visibility is evaluated can be symbolized with a specified outline color.
This is a global setting and applies to all viewsheds within the application.
See also frustumOutlineColor().
void setObstructedColor(color obstructedColor) |
Sets the color with which non-visible areas of the viewshed will be rendered to obstructedColor.
Areas of the scene view that are not visible from the observer location and within the frustum defined for the viewshed analysis will be rendered using the specified color.
This is a global setting and applies to all viewsheds within the application.
See also obstructedColor().
void setVisibleColor(color visibleColor) |
Sets the color with which visible areas of the viewshed will be rendered to visibleColor.
Areas of the scene view that are visible from the observer location and within the frustum defined for the viewshed analysis will be rendered using the specified color.
This is a global setting and applies to all viewsheds within the application.
See also visibleColor().
color visibleColor() |
Returns the color with which visible areas of the viewshed will be rendered.
Areas of the scene view that are visible from the observer location and within the frustum defined for the viewshed analysis will be rendered using the specified color.
This is a global setting and applies to all viewsheds within the application.
