Algorithm (Workflow)
This algorithm is designed to create a solid geometry strip around the sagittal plane of a given solid. The function is named SGhullstripsagittal and is part of the SolidGeometry library. Below is a detailed explanation of the algorithm and its parameters.
Input Parameters
- A: The solid object around which the strip is to be created.
- x: The x-coordinate of the strip's center. This is an optional parameter with a default value of 0.
- b: The width of the strip. This is an optional parameter with a default value of 2.
- w: The wall thickness of the strip. This is an optional parameter with a default value of 2.
Output
- X: The solid geometry of the strip created around the sagittal plane.
Algorithm Steps
- Retrieve the parameters
x, b, and w using the getfuncparams function. Default values are used if parameters are not provided.
- Create a bounding box
B around the solid A with dimensions [10 10 10].
- Set the width of the bounding box
B to b.
- Transform
B to align with A using the SGtransrelSG function, centering it at the x-coordinate x.
- Intersect the solid
A with the transformed bounding box B to create a new solid C.
- Extract the contour polygon list (CPL) from the solid
C using the CPLofSGhull function.
- Remove straight lines from the CPL using the
CPLremstraightAmin function.
- Create a new solid
X from the CPL, adding a buffer with thickness w.
- Rotate the solid
X by 90 degrees around the yx-plane using the SGrotate function.
- Align the transformed solid
X with the original solid C using the SGtransrelSG function.
- If no output is requested, plot the original solid
A and the resulting strip X using the SGplotalpha function.
