View Full Version : Boolean operations vs. memory
danshewan 09-22-2006, 01:26 PM Hey guys,
I'm trying to model a stone tablet, engraved with text in a Roman-style font. I figured the easiest way to do this would be a simple Boole object.
I used a cube (pretty small) for the tablet itself (with a minimally-modified BhodiNUT shader for the stone texture), and an extruded text spline for the text. Everything is okay until I try and add the cube (or stone tablet) object to the Boole object.
When I do this, not only does the actual cube wireframe disappear (leaving just a colored area where the texture should be), but my system starts slowing down really badly. As yet, I've been unable to figure out why this is happening. Just so you know, I'm running version 8.2, on Mac OSX 10.4.7, with 1GB of RAM with a 2Ghz processor - surely this isn't too taxing for the system to handle?
Any suggestions of alternative methods or troubleshooting my system would be greatly appreciated. Thanks,
Dan

Booleans are both memory and cpu intensive. Depends how lengthy your text is of course (10 commandments?), but imagine all the curves text contains....
If I was you I'd try using sub-poly displacement instead. And get another GB or ram.

Another option is to extrude the type.
Using Illustrator:
- set type
- type color white
- convert type to outline
- draw tablet shape
- color black
- select both
- compound paths make
- save to v 8
- open in C4D
- extrude to say ... 5
It'll take a while if you have less than 2GB ram.
You can also save to state after the extrude. You can then
leave the letters at the depth you want and pull the corner
points of the tablet to the thickness you like.

PS
I used linear cap extrude.
Here's a cu with side light.

Good idea Vid2k. And how did you get that nice chiselled bevel on the text?!?

Just a simple linear cap + 1 step + radius 1
You can make it sofetr with other cap adjustments.

Amazing--that doesn't work here no matter what font I choose. The fillet always crashes into itself at some point, or else it doesn't come close to a chiselled front. What font are you using there?

Times Roman 12pt bold
Make sure you do not check "constrain"
Make sure you stay with ngons
Make sure the step and radius are not large since that will do the same thing
Do you want the AI or C4D file ?
Here's an old image that shows how this works in a render

Yeah, I'd love to look at the .c4d file if you can send it. adamt [at] 3danvil [dot] com.

I'd also really like to see that .c4d. Anyway for you to host it? I'm sure a bunch of people could learn from it :)

Got the files, thanks (I can post if Vid2k says it's okay). This is rather brilliant in a way. You *can* do this with Cinema's native fonts/splines too, making a nearly perfect chiseled front that's completely impossible to do with extruded text absent the rectangl outline. If you check the wireframe you'll see that fillets are crashing all over the place, but it's hidden by the solid object.
Now the challenge is figuring out how to take this shape and turn it into a convex chiseled front. I'll have to give this some thought....

You're welcome Adam.
I was waiting for an email reply, LOL.
Yes, I'm happy to share the file ..... attached
Yes you can do convex ... just reverse the colors
in the AI file ... I think :)

Ahhhh now I get it :) Thanks for sharing!

Thanks :)
Here's the convex version. You need to make the type and the "tablet/base
as separate items and move the base into position ...... this is the easy version.
The harder version is to chisel the letters one at a time ... like this old example
"Medalist"

Yeah, the harder version is what I'm talking about--sweet!

Wow, thanks guys - plenty for me to get stuck into. Thanks again for the suggestions and files etc., and hopefully I'll have a WIP I can post sometime soon. Cheers,
Dan
