Creates an approximated curve from a PointsCloud.
This command can be useful if associated with the command Planar Clouds from PointsCloud. In fact, it allows you to create a curve from point clouds on planes. The input cloud can be not planar.
Attention: the sort criterion is the lowest distance from points. You can obtain undesired result if your cloud has point subsets with the same distance themselves.
How to use
1. Click the Curve from PointsCloud icon or choose the Tools > PointsCloud > Curve from PointsCloud command.
2. The program console prompts Pick a PointsCloud.
3. Select the PointsCloud. If you select the cloud from the browser, the program console will also prompt you the Init point message. Select with the mouse a point on cloud. This is the guess point for point sort and the curve starting point. If you select the cloud in the interactive views the picking point will be the start point.
Options
PointsCloud
To change the PointsCloud.
Views / Modeling Tool panel. Switch the Replace check button on and pick another PointsCloud in the scene.
Curve type
To generate Open or Closed periodic curve.
Modeling Tool panel. Switch the chosen radio button on.
Fitting
To choose the curve generation method.
Modeling Tool panel. Switch the chosen radio button on.
You have the following choices:
Approximate. Creates an approximated curve. When you choose this option, you should also specify the minimum distance from a point to the other points (Dist. Tolerance parameter) and the curve order (Order parameter).
Interpolate. Creates an interpolating curve.
PointToCV. Points on cloud will be the curve control points. You can type the curve order in the Order section.
Order
To define the curve order in case you have chosen Approximate and PointToCV fitting options.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.
Dist. Tolerance
To set the tolerance for excluding ìirregularî points on cloud: if the minimum distance from a point to the other points on cloud is higher than this parameter, the point is out of sort processing.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.
