siren - Lightweight 3D operation environment

siren is lightweight 3D operation environment powered by Open CASCADE Technorogy. siren is integrated to mruby; lightweight Ruby interpreter environment, so it gives high-level 3D geometrical and topological operation with easy and simple scripting. For example, you can get volume of shape, intersection lines of some shapes, center of gravity and a result of boolean operation. It supports IGES, STEP file with NURBS surface and curve.

You can get more information at siren official page.

Example

# Make two boxes
box1 = Siren.box [10, 10, 10]
box2 = Siren.box [10, 10, 10]

# Move box2
box2.translate! [5, 5, 5]

# Fuse two boxes
box3 = box1.fuse box2

# Print volume of box
p box3.volume # => 1875

box3.faces do |face|
  # Print area of face
  p face.area
end

3. Add conf.gem :github => "dyama/mruby-siren" line to mrbgems/default.gembox.
4. Make mruby.

If your OCCT installed path is not /opt/occ<version no>, you should change mrbgem.rake file in build/mrbgems/mruby-siren. Default install path is;

• /opt/occ/710 ... for Linux
• /usr/local/opt/opencascade ... for Mac OS X
• \occ\710 .. for MinGW64

Usage

• Run /bin/mirb.

  $ cd ~/mruby/bin $ ./mirb

• Run /bin/mruby with siren script.

  $ cd ~/mruby/bin $ ./mruby script.rb

• To specify the library path

  $ LD_LIBRARY_PATH=/opt/occ/710/lin64/gcc/lib ./mirb $ LD_LIBRARY_PATH=/opt/occ/710/lin64/gcc/lib ./mruby script.rb

Or add the library path to /etc/ld.so.conf.
