1. Inclusions rendering

Table of Content

In this inclusion rendering demonstration, you can see how different types of defects affect the gemstone's appearance.

There are three default defects: a surface reaching large crack and two coupled solid material inclusions. While the appearance of the latter is only affected by the diffuse lighting (depends on panorama in question), the crack also exhibits reflective and transparent appearances depending on the observation parameters.

To see inclusions demo select from menu File / Crack - inclusion demo in the DiamCalc 3.2 Demo version

New Oxygen Microscope / Oxygen Inclusion 3.0 beta allow making export of allocated polished diamond with its inclusions and textures and HeliumPolish scanned models into DiamCalc file.

2. Non convex (concave) cut renderings are supported

Table of Content

Now DiamCalc supports photorealistic rendering for concave cuts.

3. Importing non convex cuts from binary STL

Table of Content

Now import for non convex cut is supported from binary STL. Previous versions supported import from binary STL format of convex cuts only.

4. Stars effect

Table of Content

Stars effect is a feature which appears in real life when a bright object is observed in darkness, and there is an occluder object in front of it.

In case of human eye, eyelashes could be such occluder, producing stars effect. In case of camera, polishing or scratching on the objective causes occludes.

Different occluder images can be chosen from the program kit:

Camera occluder example Stars effect

5. Export movies for iPod / iPhone using DC QuickTime exporter

Table of Content

Export QuickTime movies (MOV) for iPod / iPhone is available.

To export QuickTime movie:

  • Press button Movie menu
  • Choose Record:
  • Set movie recording options
  • Press Ok
  • The recording will proceed. Press Stop when movie is ready
  • Choose Export to MOV:
  • Save file *.mov
  • Import *.mov file into your iTunes
  • Select *.mov file in iTunes and Right click mouse on it
  • Select Create iPod or iPhone Version in context menu to convert movie for your iPod / iPhone

6. Creating layer through three points in the Cut Designer

Table of Content

Creating layer through three points is a new flexible method for creating cut. One of the main advantage of this method is you need not to know and set Gear indexes and slope angles while you create layers of facets (see example in the section Creating Gabrielle cut through three points. Variant 2 in the DiamCalc 3.2 beta Documentation, PDF).
