COUNTRY: Greece (Hellas) WEBPAGE: http://corfu.forthnet.gr/nobelis/index.html RENDERER USED: Imagine 3.0 PC TOOLS USED: Just Imagine 3.0 Amiga RENDER TIME: A few minutes! Who cares... HARDWARE USED: Pentium 133 IMAGE DESCRIPTION: A couple of glasses with straws and a brown background DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I didn't care much! I wanted to see how a PC aould render glass and compare it to my Amiga. It was made sometime in 1995. I took a sphere and put another sphere inside it. Changed the inside sphere's attributes to TRANSPARENCY (I need to look at my notes for that one!) and the outside sphere's to glass (for glass just ask Conny at www.is.kiruna.se/~cjo and I am sure he'll know!). I made a tube and used the same glass attributes. Grouped all objects and used the SLICE option of Imagine to cut the top off the two spheres. The glass was ready... A third sphere with MILK attributes (should I be proud of how realistic I can make glass?) was SLICEd again to be leveled lower than the tip of the glass. now here is the cool part! I wanted to simulate the whole milk's surface tention effect and used some other feature of Imagine to make that side curve. However, I forgot to do the same for the straw's interaction with the surface and you can clearly see that part is bad! For the straws I used simple tubes but I didn't like the typical semi-transparent straws so I just made it some _plastic_like_ red (looks like poly-propelene to me! I rendered at 512x400 on a PC and Imagine crashed on me about twice while making the objects as I remember. The picture is not good but I thought I'd put it up anyway. If anyone likes the glass attributes I can look at my notes and submit it to the Imagine mailing list. Did you notice how bad the polygons look on the glass surfaces?
