Embedded Files
Here are some of my models, true three-dimensions (3D), and are in the VTU file format.
They can be viewed using the Virtue3D-Optimizer (downloaded here too). Unrar, and run.
For sample imagery of my fractals, seashell collection etc., please view them in the appropriate pages.
Notes for the viewer:
1. keyboard shortcuts: Backface on/off ('B'), Texture on/off ('T'), Headlight on/off ('H'), Smooth/Flat/Wireframe shadings ('G','F','W').
2. it is possible to get a reflective surface of models by:
Applying the menu View->Environment->ReflectionMap.
Applying "reflection" checkbox on selected shape (in Appearance tab).
Turning the Texture off in the 3d-view window (key "T").
Have fun!
Solar System with all planets and major moons in 3D motion
Some models have animation, such as "Cyclides", which is a topological transform used in approximating surfaces.
Some models from the Aliquot Sequences are represented in 2D (Tree_901.gif) and 3D (Tree_901.gif , Tree_901.vtu) - are worth comparison.
The Aliquot-Forest model (AliquotForest_Globe71.vtu) displays 71 trees growing on an invisible globe, colored each in a distinguishable shade.

Naming obviously originates in Omar Kha'iam's celebrated quatrains (highly recommended).

Swirling gems - the incredible beauty of design cuts of precious gems
As part of my job in the diamonds industry, I was working with the geometry of gems as well as raw stones. This is a selection of precious gems design cuts.
Designs: Barrel, C32, Cart Wheel, Cushette, Cushion, Oval Classic, Penta Star, Radiant Classic, Radiant Square, Round Brilliant, Spider Gem, Tiger Eye, Triang Cushion
Squid-game flower
KALI designs: Compartment Virus , Tatrahedral Bacteria, Mantises & Monkeys
KALI designs: Scorpions & Snails , Passion Flower , Rhino Virus
"Pillows" seashell with KALI texturing
The Burning Bush - hallucy
Robot Battle: a programming game of designing robots that would fight other robots with the same resources, to find out better designs.
Played this for years, with multiple designs and tournaments. Below is a friendly version of a team of bots that coordinate their movements to shoot mines, avoid lethal crashes, and feast on cookies.
Sample code of the Cookie Monster bot (a short, initial version, in Robot Battle language):
Init{ name("CukyMonster") author("Ophir Spector") version("3") R = 7447 # ORDERCUKY radio code R.id = _id bots = _robotsTotal Cuky[bots] = 0 lockgun(1) blocking(0) radioChannel(3) regRadio(Radio,1) regCldRobot(Crash,2) regDtcMine(ShootMine,3) regDtcCookie(GetCuky,4) regCore(Core)}
