Introduced first in SolidGeometry 2.0, Creation date: 2014-12-09, Last change: 2025-09-14
plots a tetrahedron list as one volume or as separated tetrahedrons
Description
uses tetramesh to print all tetrahedrons in one step.
Each tetrahedron is plotted seperately (slow)

Algorithm (Workflow)
This algorithm is designed to plot a list of tetrahedrons using the function VLTLplot. It utilizes the tetramesh function to render the tetrahedrons either as a single volume or as separate entities.
Input Parameters
- VL: Vertex list - A matrix containing the coordinates of the vertices.
- TL: Tetrahedrons list - A matrix where each row represents a tetrahedron by indexing into the vertex list.
- c: Color - An optional parameter to specify the color of the tetrahedrons. Default is 'r' (red).
- so: Single handle - An optional boolean parameter. If true, all tetrahedrons are plotted as a single graphics object. If false, each tetrahedron is plotted separately. Default is true.
Output
- h: Handles to graphics object - Returns handles to the plotted graphics objects.
Algorithm Steps
- Check if the vertex list
VL or tetrahedron list TL is empty. If either is empty, return an empty handle h.
- Set the default color
c to 'r' (red). If a color is provided as an argument, use that instead.
- Set the default for
so (single object) to true. If a value is provided, use that instead.
- Set the colormap using
VLcol and determine the color mapping cmc using the specified color c.
- Set the color limits with
clim([0 7]).
- If
so is true, plot all tetrahedrons as a single object using tetramesh with the color applied to all tetrahedrons.
- If
so is false, iterate over each tetrahedron and plot them individually using tetramesh.
- Call
VLFLplotlight(0,1) to adjust the lighting of the plot.
