I created this about 30 years ago. The point is that it is NOT a photo and top pros have not been able to pick that up about this image.

Comments?

Hi Tegan,

I love games. If it's not a photo it would be hard to tell what it is by viewing it on a monitor. Is it a lithograph or serigraph?

Neither, but it is in 3 dimensions.

Well I'm stumped. But to be honest, I'm not sure it's a fair test. I mean what we are looking at IS a photo right. (You had to photograph the object to upload it)
Now that it IS in 2 dimensions - much harder to say what it WAS/IS

Still I'm competitive and it's bugging me......maybe I'm stretching but could the white material be a kleenex or a hanky?

Now to really confuse you. :D No I never used a physical camera at all to create it. It was_is in 3 dimensions and by that I mean the image but you need something to go through this image in three dimensions and to see it from the top, side, back, etc. By the way, the white material was NOT material at all.

Ya got me and now I'm darn curious.

Do tell...

I used an Amiga computer which had a small memory of 16 meg and a slow turtle speed of 16 megahertz (as opposed to 3 gigahertz). At the time it was great.

The clouds are created by a fractal program. The reflections in the water are created by a ray tracing program based on physics parameters. The iceberg was first created as a combination of triangles, pentagons, polyhedrons etc and then I mapped the white texture on to it. I used a program called 3D Professional. I added the clouds and water into the picture as a somewhat blocky sketch on the screen. Remember what I had on the screen was a 3D image on a 2D screen which makes image work rather complicated to say the least.

The next step was to bring out the software virtual camera and put it into the scene. I had to determine where to place the camera in the virtual scene as well as what lenses and filters to use. I also had to place the sun, control and diffuse the light and control shadows.

Once I got everything together on the monitor, apparently in the right place in 3 dimensions. (difficult on a 2 dimensional screen), I then set the image to render. Rendering is a process where all the lighting, lens, filters, reflections, colours, texture, angles, decisions are calculated and produced as a complete image on the screen. It took 24 hours.

The 3D program is of course necessary to see it in 3 dimensions or to move around in the image.

Complicated but I hope you understand that iceberg was completely created on a primitive computer by today's standards but it is one of my most interesting works because of that.

WOW. I could have lived 3 lifetimes and never guessed.

Thanks for telling, it was killing me, and no matter how it was created, NICE SHOT!

Thanks

that's cool picture
