Algorithm (Workflow)

This function, SGmodelMass, is designed to create a mass point with two frames using the SG-Library. It is a part of the SIMMECHANICS INTERFACE and was developed by Tim Lueth.

Input Parameters

Output

Algorithm Steps

  1. Initialize the radius R to 1. If an argument is provided and is not empty, set R to the provided value.
  2. Create a sphere with radius R using the function SGsphere(R) and assign it to SG.
  3. Create a box with dimensions [R*2, R*2, R*2] using the function SGbox and assign it to SG.
  4. Set the color of the solid geometry SG to magenta ('m').
  5. Set the transformation of SG for frame 'B' using the function SGTset with an identity matrix and a zero translation vector.
  6. Set the transformation of SG for frame 'F' using the function SGTset with an identity matrix and a zero translation vector.
  7. If no output is expected (nargout==0), plot the solid geometry using SGfigure, set the title using titleofcaller, and view the plot from a specific angle using view(-30,30). Finally, plot the solid geometry with SGTplot(SG).
