Hello
For those who want to experiment with hand drawn holography art,
here is a site http://3dalter.50megs.com/ with a program
for making scratch patterns from .3ds objects, and some suggestions too.
Raúl.

I alway thought it would be neat to make the scratches into a hologaphic film using a laers and and x-y table with stepper motors....

Here is a video clip of a monster's head hand-drawn hologram, made using 3dSilhouette program.

I think the major problem with trying to make scratches digitally rather than by hand wih a compass is that for best signal to noise ratio, the scratch must be smooth and continuous and not a stairstep approximation. Each scratch is a curved mirror which reflects a point of light with apparent position depending on the radius and viewing angle and if it is not a smooth arc, the parts that deviate from the ideal arc will reflect light at the wrong angle, creating a noisy image. Maybe if the resolution was very very fine (microns?), the problem would diminish?

Hi Raul,
Can you email me the software? colin at holographyforum dot org.
It looks like fun.

For those whol do not know about the original work see here:

I made a few when I first found this page.

This one is great, Raul
What was the model ?
Did you use equal depth pages ?
Did you draw with compass or with machine ?
How long did it take you to draw scratches ?
greetings
Adam

Thanks Adam
I used a 3d Head made with 3dMeNow program that generates 3d heads from profil and front photographies of a person.
With equal depth pages, 46 pages where generated (depth from 30 to 120), but printed only 23, I merged them by pairs
for saving paper.
Hologram was drawn with a compass on A4 transparency sheet, it took approximately 4 hours to completion.
Regards,
Raul.

I have been playing with Raul's software and it is quite fun. I am excited about trying another Scratch-O-Gram. Raul kindly provided me with the information to make a wiki entry here:
http://www.holographyforum.org/HoloWiki ... tch-O-Gram
The software is stored on The Holography Forum server.
Thank you Raul!
