Cone Of Vision - [source code]

Use this component to generate and visualize cones of vision.

This component can help you to customize view analysis. Plug its outputs into Ladybug_View Analysis.

Inputs

  • type [Optional]

This input sets the cone of vision, the cone is defined by four values that are vertical angle+, vertical angle-, horizontal angle+, horizontal angle-, distance limits.

Connect a number from 0 to 9. The default is set to 0.

0 = Human (50°, 70°, 62°, 62°, 10 meters) 1 = Peripheral vision (60°, 70°, 60°, 60°, 10 meters) 2 = Outdoor (90°, 15°, 180°, 180°, 100 meters) 3 = Car at 25 mph (50°, 15°, 50°, 50°, 182.88 meters) 4 = Car at 45 mph (50°, 15°, 33°, 32.5°, 365.76 meters) 5 = Car at 65 mph (50°, 15°, 22°, 20°, 609.60 meters) 6 = Color Recognition (30°, 40°, 30°, 30°, 10 meters) 7 = Sign Recognition (30°, 40°, 15°, 15°, 10 meters) 8 = Word Recognition (30°, 40°, 5°, 5°, 10 meters) 9 = Optimal Video Display Area (0°, 30°, 30°, 30°, 10 meters)

If no value is provided, it will be 2 ("Outdoor").

  • viewPoint [Default]

The point of vision in which to generate the cone of vision. If not supplied, default value will be the Rhino origin.

  • viewDirection [Default]

A vector that represents the view direction. If not supplied, default value will be the vector of Y-Axis.

  • distanceLimit [Optional]

Set the limit of the view.

This input let you customize the cone of vision.

  • vAngleUp [Optional]

The vertical angle of the upper visual field. A number from 0.0 to 90.0.

This input let you customize the cone of vision.

  • vAngleDown [Optional]

The vertical angle of the lower visual field. A number from 0.0 to 90.0.

This input let you customize the cone of vision.

  • hAngle [Optional]

The horizontal angle from the standard line of sight. A number from 0.0 to 180.0.

This input let you customize the cone of vision.

Outputs

  • readMe!

...

  • coneOfVision

Brep that represent the cone of vision.

  • parameters

Connect this list to Ladybug_View Analysis for customizing the view analysis.

the parameters are vertical angle+ (°), vertical angle- (°), horizontal angle (°), distance limit (meters), view direction in the horizontal plane (°). NB. 0° is the direction of green axis of Rhino.
