  9. Shape Generator for DDSCAT

    07 Sep 2015 | | Contributor(s):: Manoj Seeram, Gregory T. Forcherio, donald keith roper

    This Matlab Graphical User Interface walks users through creating custom 3D shapes. It then generates the target and parameter files that are required to simulate the created shapes in the Discrete Dipole Approximation software.

  10. dimension of the object

    Closed | Responses: 1


    I have been able to obtain exact dimension of the object by utilizing the scale in Blender. e.g. i draw a cylinder with length of 25 blender units and diameter 7.5 blender units....
