Algorithm (Workflow)
This function, VLFLboxT, generates a 3D box model with optional parameters for size and transformation. It is part of the SG-Library and is used for creating housings or flange plates.
Input Parameters
- T: Transformation matrix applied to the box.
- sz: Size in the z-direction. Default is 1.
- sx: Size in the x-direction. Default is 10.
- sy: Size in the y-direction. Default is equal to
sx.
- dz: Position change in the negative z-direction. Default is 0.01.
- R: Radius of a hole in the plate to remove SLS material. Default is 5.
Output Results
- VL: Vertex list of the box.
- FL: Facet list of the box.
Algorithm Steps
- Initialize default values for
sz, sx, sy, dz, and R.
- Override defaults with user-provided values if available and valid.
- If
dz is less than or equal to 0, set R to 0.
- Define a base plane
PL using sx and sy.
- Generate the vertex list
VL by transforming the base plane and its elevated counterpart using VLtransT.
- Calculate the facet list
FL for the sides and top/bottom of the box.
- If
R is greater than 0, ensure R is not too large relative to sx and sy.
- Create a circular hole in the plate using
PLcircle and adjust the vertex and edge lists accordingly.
- Close the volume with
VLFLcloseVLELh and apply transformations.
