I've seen lots of problems with height-fields not being smooth but I'll give it
a try. Can I put media in a height-field?

You can make grid of spheres according to trace() intersections. Radius of
spheres is radius of smoth beveled text. If you don't like it you can check
utils at http://www.povray.org/links/3D_Programs/Fonts_and_Font_Utilities/

Thanks, I think I'll try that.

I believe the original author of the bevel macro was Chris Huff. It's a
great macro, but doesn't work well on certain fonts. It's easily converted
to work on any object that has a flat face. Here's the macro, along with a
usefull "Italicize" macro, and an example picture of both macros in action.
However, for the particular image that you're working on, I agree that
another method is needed to produce that type of bevelling.
Regards,
Dave Blandston
//BevelText (String, Cuts, BevelAng, BevelDepth, Depth, Offset)
//String: the text string
//Cuts: the number of "cuts" to use to get the bevel effect. Multiple of 4
is best.
//BevelAng: the angle of the bevel.
//BevelDepth: the thickness of the bevelled portion.
//Depth: the total thickness of the text object
//Offset: the offset vector for the text object. Might screw stuff up...
#macro BevelText (String, Cuts, BevelAng, BevelDepth, Depth, Offset)
union {
text {ttf "sfb_____.ttf", String Depth - BevelDepth, Offset}
intersection {
#local J = 0;
#while (J < Cuts)
#local A = 2 * pi * J / (Cuts);
#local CA = cos( radians (BevelAng));
#local SA = sin (radians (BevelAng));
text {ttf "sfb_____.ttf", String BevelDepth, Offset
translate -z * (BevelDepth - J * .0001)
Shear (x, y, <cos (A) * SA, sin (A) * SA, CA> / CA)
} //text
#local J = J + 1;
#end //#while
} //intersection
translate z * BevelDepth
} //union
#end //macro BevelText
#macro Shear (A, B, C)
matrix <A.x, A.y, A.z,
B.x, B.y, B.z,
C.x, C.y, C.z,

#macro Italicize ()
matrix < 1, 0, 0,

Example Usage:

Italicize ()
texture {YourTexture}
} object

Nice logo!
You might be able to simulate the effect of the "print" text using Chris
Huff's BlobObject macros (sent to
povray.text.scene-files newsgroup on 20/03/2001)

Yes. just remember to make the HF hollow. (I've forgotten that bit far
too many times...)
And the smoothness of the HF depends on the resolution of the image used
to make it. If you've got the memory, then make them as big as you
can...
Bye for now,
Jamie.

I've set my Outlook Express to delete posts older than a day because the HDD got
full, so I can't search from here. I did an advanced search on news.povray.org
but didn't get anything. Could you or Chris maybe e-mail it to me at
jpr### [at] citywalkcoza please? I think it should do the job for me.

Gee... are you good with CorelDraw!!!
Where do you want the photons? Why don't you just make them in Corel,
too? Personally, I've made anisotropic blurred reflection in PhotoShop
so I know it can be done :)

Thanks :)
The shadow tool in CorelDraw helped a lot with that. You could even do an
airbrush effect if you wanted, with beziers and the shadow tool =)

With Corel I imagined what it should look like and then did it. With Pov, I want
to make it look like it would if it were in RL with photons and radiosity.

I can't remember what photoshops blur looks like but Corel has a nice guassian
blur.

I know. I use Corel, too. Otherwise I wouldn't have known you were
that good :)
I still suggest you do them by hand, though. You'll have more artistic
control this way.
