Algorithm (Workflow)
This algorithm is designed to perform a z-sweep on a given Contour Vertex List (CVL) and return a swept CVLz contour along with a 2.5D solid representation.
Input Parameters
- CVL: A sliced contour represented as a Contour Vertex List.
- varargin: Additional optional parameters for the sweeping process.
Output Results
- CVLn: The resulting swept CVLz.
- SG: The 2.5D solid representation of the swept contour.
Algorithm Steps
- Extract unique z-values from the CVL using the
unique function and remove NaN values with woNaN.
- Initialize variables:
n for the number of unique z-values, olap for overlap, and empty arrays CVLn and SG.
- Iterate over each unique z-value:
- Separate the CVL at the current z-value using
CVLseparatez.
- Sweep the contour using
CPLsweep with optional parameters.
- If not the last z-value, create a solid geometry slice using
SGofCPLz and concatenate it to SG using SGcat2 and SGtransP.
- Add the z-value to the contour using
VLaddz.
- Append the processed contour to
CVLn and separate slices with NaN values.
- Remove the last NaN separator from
CVLn.
- If no output arguments are specified, plot the results using
SGfigure, CVLplot, and SGplot with lighting adjustments.
