Algorithm (Workflow)
This function, VLmeshgrid, is designed to generate a list of 3D mesh coordinates based on input vectors for x, y, and optionally z dimensions. It is part of the SG-Library and was introduced in SolidGeometry 4.0.
Input Parameters
- xx: A list of x values.
- yy: A list of y values.
- zz: A list of z values. If not provided, defaults to 0.
Output
- VL: A point list of all mesh coordinates.
Algorithm Steps
- Initialize
zz to 0. If a third argument is provided and is not empty, set zz to this value.
- Use the
meshgrid function to create 3D grids XL, YL, and ZL from xx, yy, and zz.
- Reshape these grids into column vectors and concatenate them to form the output
VL.
- If only two input arguments are provided, adjust
VL to include only the x and y coordinates.
- If no output is requested, plot the points using
SGfigure and CVLplot. Adjust the view based on the number of input arguments.
Example Usage
VLmeshgrid(1:3,1:2,10): Generates a mesh grid with x values from 1 to 3, y values from 1 to 2, and a constant z value of 10.VLmeshgrid([0 15 25 35 45 55 65],0:8:8*22,[10 20]): Generates a mesh grid with specified x values, y values from 0 to 176 in steps of 8, and z values of 10 and 20.
