The Gemstones program creates gemstone objects of several styles, displays them and exports them for other 3D programs to use.
I am releasing the source in case you would like to learn how it works and modify it. I would appreciate it if you would let me know of any interesting modifications that you make.
The Gemstones program displays various gemstone shapes and allow rotation to examine the shapes.
Objects can be saved to OBJ graphic files for import into graphics environments.
The large picture above was created by RayDream 5.5 after importing the shapes. The other pictures were created by screen capture from the program.
Colored lights and White, Black and Gray backgrounds are now available.
To review the gem as it is created:
With Version 2.5, animation is mouse driven rather than keyboard driven. Weren’t you tired of clicking the keys?
To rotate the view, just click on the window and drag with the mouse. Clicking stops any current motion and dragging rotates the view.
To rotate around the Z axis, move drag the cursor near the edges of the window.
To spin the object, release the mouse while still moving. Spin it fast or slow, it keeps the motion it had when you released the mouse.
To zoom the view, use CTRL with the mouse.
To move the view, use SHIFT with the mouse..
- Version 2.9, 16 May 2001, Animation defaults off. Mouse turns on animation when required. Program is much more CPU friendly.
- Version 2.8, 15 April 2001, Startup is much faster. State is saved.
- Version 2.7, 6 April 2001, Correct problem with closing program when minimized.
