Algorithm (Workflow)
This algorithm is designed to arrange multiple solid geometries side by side, preparing them for a joint 3D print job. The function SGCpack takes in a solid geometry collector, a solid, and an optional number of parts to add.
Input Parameters
- SG: A solid geometry collector, which can be empty initially.
- B: A solid, represented by vertex list (VL) and face list (FL).
- n: An optional parameter specifying the number of parts to add. Defaults to 1 if not provided.
Output
- SG: The updated solid geometry collector with the new solids packed.
Algorithm Steps
- Check if
B is not a cell array. If it is not, proceed with the following steps:
- Initialize
maxs as [150, 30, 150] and sx as 1.
- Calculate the bounding box of
B using BBofVL.
- Determine the number of parts
n to add, defaulting to 1 if not specified.
- For each part to be added (from 1 to
n):
- If
SG is empty, initialize its vertex list, face list, and bounding list. Otherwise, calculate the bounding box of SG.
- Calculate the new x, y, and z positions for the solid based on the bounding boxes and spacing
sx.
- If the new x position exceeds the maximum size, reset x and adjust y position.
- Transform the vertex list of
B to the new position and concatenate it with SG's vertex and face lists using VLFLcat.
- Update the bounding list of
SG with the new bounding box dimensions.
- If
B is a cell array, iterate over each element and recursively call SGCpack for each solid.
- If no output is expected, plot the solid geometry using
SGplot and display the bounding list.
