Task
Write language name in 3D ASCII
You are encouraged to solve this task according to the task description, using any language you may know.
Task

Write/display a language's name in 3D ASCII.


(We can leave the definition of "3D ASCII" fuzzy, so long as the result is interesting or amusing, not a cheap hack to satisfy the task.)

Quotes are not escaped by \ in ada (nor does \ have any meaning in strings), so this turns out highlighting funny.

ZX Spectrum Basic

We have used an extended (non-ASCII) character in this example to produce an inverted space symbol (143 on the spectrum character table), for simplicity. We could substitute another character, and change the handler to cause a colour switch using a traditional space (ascii 32), but the output would still look the same. Fixed the error and removed the need for 2^z.

  10 DIM b(5,5): REM our bigmap characters
  20 FOR l=1 TO 5: REM 5 characters
  30 FOR m=1 TO 5: REM 5 rows

To me it does not work. So I bring my particular solution:

120 RETURN 
130 DATA "XXX  XXXX XXX X XXX"

Bit of a long one,but it works and it does something other than taking strings and simply copying to STDOUT. (It adds line offset to those strings,and the strings are encoded with numbers just because.)

Go

Go does have a "Go" logo, although it is rarely used. A graphic is at http://golang.org/doc/gopher/bumper.png and the logo is the word Go with the two little lines to suggest movement. It's not 3D, so for inspiration I googled 3D ASCII fonts or something similar and found Patrick Gillespie's site at patorjk.com/software/taag/ with lots of ASCII fonts. The first one I liked was "Block" for its simple 3D illusion of drawing only the shadow, then I found "Lean." It's the same 3D effect as Block only slanted, reminiscent of the slanted Go logo.

For the interest component of the task, I thought about rendering the result from an input string and realized that it wasn't completely trivial as the glyphs of the Lean font overlap with the standard letter spacing. Rendering different fonts would add interest because now there would be a point in developing a common font representation and rendering function. Block and Lean would have sufficed, but I looked further and found the Keyboard and Small Keyboard fonts. These I found somewhat amusing, for the final component of the task.

package main

import (
    "fmt"
    "strings"
)

var lean = font{
    height:  5,
    slant:   1,
    spacing: 2,
    m: map[rune][]string{
        'G': []string{
            `  _/_/_/`,
            `_/      `,
            `_/  _/_/`,
            `_/    _/`,
            `  _/_/_/`,
        },
        'o': []string{
            `        `,
            `  _/_/  `,
            `_/    _/`,
            `_/    _/`,
            `  _/_/  `,
        },
    }}

var smallKeyboard = font{
    height:  4,
    slant:   0,
    spacing: -1,
    m: map[rune][]string{
        'G': []string{
            ` ____ `,
            `||G ||`,
            `||__||`,

            start = f.height

        for i := range rows {
            rows[i] = strings.Repeat(" ", (start-i)*f.slant)
        }
    }
    if f.spacing >= 0 {
        spacing := strings.Repeat(" ", f.spacing)
        for j, c := range s {
            for i, r := range f.m[c] {
                if j > 0 {
                    r = spacing + r
                }
                rows[i] += r
            }
        }
    } else {
        overlap := -f.spacing
        for j, c := range s {
            for i, r := range f.m[c] {

        }
    }
    return strings.Join(rows, "\n")

Explanation: the argument says where to place the solid "blocks". Each block is described by three integers, describing position along the x, y and z axis. In other words, 1 0 0 is one position to the right of 0 0 0, while 0 1 0 is one place down and 0 0 1 is one place towards the observer. (Thus the space at the top of the "slimmer" version could have been eliminated by subtracting 2 from the middle column of integers being passed to 'view'.)

It's convenient to encode these three element values as ascii characters. The original used base 5 (after subtracting 21), the alternate version used octal (after subtracting 32).

Note that the order the block positions are described in is irrelevant (the characters indicating position could be shuffled with no change in the rendered result).

Java

This was written ages ago as an exercise in obfuscation, and improved here with upper case letters. The font is "lean" from figlet.

It's not really that obfuscated. The characters in z are used to draw the letters. The array f contains one element per letter of the alphabet. Each array element is another array of 7 longs because each output letter is made of 7 lines of text. Each long value represents a sequence of 2-bit integers that are extracted by bit-twiddling and used to find the right character in z.

    char[]z={' ',' ','_','/',};

jq

Works with gojq, the Go implementation of jq

One small point of interest here is the use of string interpolation to simulate a "heredoc" string.

def jq:
"\("

                #
               #     #   ###
              #      #  #   #

        #   #    #   #   ####

                            #
")";                 

def banner3D:
  jq | split("\n") | map( gsub("#"; "╔╗") | gsub(" "; "  ") )
  | [[range(length;0;-1) | " " * .], . ] | transpose[] | join("") ;

Raku

(formerly Perl 6) Produces a good old-fashioned stereogram, meant to be looked at by focusing beyond the screen, not by crossing your eyes. If you can't get it to converge, try shrinking the font size till the images are closer together than your eyes. Also helps to be old enough to have progressive lenses, so you can look through the reading part of your glasses. Or borrow glasses from someone who's farsighted. :-)

REXX

block characters

The REXX program works in   ASCII   or   EBCDIC.

It's astonishing how much time I wasted spent on this program.
Most of the time was spent on writing comments, but the code was so easy to read, so the comments were elided.  

This REXX has been used as part of a test suite for some REXX interpreters to stress test their syntax parser.

simpler, shorter

This is a version of the above REXX program (with a minor bug fixed),
the input text has additional spacing between the   letters   for better readability,
the letter   E   (in the input text) was shortened,
the output doesn't have extraneous leading blanks,
the output doesn't have trailing blanks,
the input text can be any consistent non-blank character except the forward slash   (/)   or backward slash  (\).

/*REXX pgm draws a "3D" image of text representation;  any character except  /  and  \  */

This works in Oracle. For other databases, try it without "from dual".
