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

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.

//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,
0, 0, 0>
#end //macro Shear
#macro Italicize ()
matrix < 1, 0, 0,
.2, 1, 0,
0, 0, 1,
0, 0, 0>
#end //macro Italicize
Example Usage:
object {
BevelText ("Hi There, Sportsfans!", 16, 45, .04, .2, 0)
Italicize ()
texture {YourTexture}
} object
