poICFD SetMaxBreakAngle

Specifies the threshold value for the break angle between two neighboring streamline segments, which is used to decide if the two line segments should be merged into one, or kept untouched.

Syntax

poICFD_handle SetMaxBreakAnglebreak_angle

Application

HyperView Tcl Modify

Description

This command specifies the threshold value for the break angle between two neighboring streamline segments, which is used to decide if the two line segments should be merged into one, or kept untouched. This command will only take effect when streamline decimation is turned on by calling the SetStreamLineDecimation command. The valid value range for the break_angle is from 0 to 90 degrees.

Inputs

break_angle: The break angle threshold for decimation to be set.

Example

To specify the break angle threshold for streamline decimation to "2 degrees":

Error

Returns HW_InvalidArgs if the specified break_angle is not valid.
