Script Modeling

  • You can create 3D model even if you

are not familiar with 3DCG/CAD software

  • You can create shapes that are

difficult for hand creation

  • Modifying shape is easy

SLIDE 21

What is Blender?

  • Developed since 1995
  • Open source software, Multi platform
  • Language: C, C++, Python
  • Python is used as API interface
  • Blender has its own python interpreter in the

software（3.5.1 in Blender2.77a）asyncio!!

Script Modeling with OpenSCAD and Python

slide-54
SLIDE 54

What is OpenSCAD?

  • CAD software, Open source (GPL)
  • Multi platform（Win, Mac, Linux）
  • Implemented by C++(Qt)
  • Create 3D model using original programming language
  • No GUI to manipulate 3D data
slide-55
SLIDE 55
slide-56
SLIDE 56

Feature of OpenSCAD

  • Very good for Software Engineer
  • Written script can be kicked from command line
  • Generate model in Server
  • Create multiple model with command

Generate by 1 command

  • You can pass arguments from command line to OpenSCAD

script

slide-63
SLIDE 63

OpenPySCAD

  • Generate OpenSCAD code from Python code
  • https://github.com/taxpon/openpyscad
  • Install via pip command

$ pip install openpyscad

slide-64
SLIDE 64

OpenPySCAD

  • Union operation

Cube([20, 10, 10]) + Cube([10, 20, 10]) union(){
 cube([20, 10, 10])
 cube([10, 20, 10])
 };

slide-65
SLIDE 65
  • Difference operation

Cube([20, 10, 10]) - Cube([10, 20, 10]) difference(){
 cube([20, 10, 10])
 cube([10, 20, 10])
 };

OpenPySCAD

slide-66
SLIDE 66

OpenPySCAD

  • Rotation

c1 = Cube([20, 10, 10]) c1.rotate([0, 0, 45]) rotate([0, 0, 45]){
 cube([20, 10, 10])
 };
