Add preview of 1984-2019
The 2020 winners are hinted it, but the source code is not there,
nor are the hints. Someone could look into the HTML and
see what was commented out, but that is not a problem because
WHO won is known and the name of their AWARD is known already.
Moreover a number of the winners have talked about what their
entirs do, so the commented out spoiler text is not a bit problem.
One will find HTML commented out with:
<!-- XXX remove when 2020 is ready
2020 links here
XXX remove when 2020 is ready -->
The "XXX remove when 2020 is ready" string is found at the
start and end comment blocks. Again, soneone could read
what was commented out, but that is OK since most of that
information is known or can be known. The following files
have such HTML comment blocks in them.
./winners.html
./years-spoiler.html
./years.html
In addition, ./all/summary.txt was modified to not
include the 2020 entries for the momemt.
The 2020 winner code AND write-ups are NOT part of this set.
p.s. The all/all.tar.bz2 does not contain the 2020 source code (yet?).

<h2>Judges' comments:</h2>
|
||||
|
||||
<h3>To build:</h3>
|
||||
|
||||
<pre><code>make endoh4
|
||||
</code></pre>
|
||||
|
||||
<h3>To run:</h3>
|
||||
|
||||
<pre><code>./endoh4
|
||||
</code></pre>
|
||||
|
||||
<h3>Try:</h3>
|
||||
|
||||
<p>NOTE: The author recommends the use of xterm.</p>
|
||||
|
||||
<pre><code>./endoh4 < cube.txt
|
||||
</code></pre>
|
||||
|
||||
<p>For example, if you are a soccer fan, try:</p>
|
||||
|
||||
<pre><code>make all
|
||||
./endoh4 < solids/archimedian-solid/a11-truncated-icosahedron.txt
|
||||
</code></pre>
|
||||
|
||||
<h3>Selected Judges Remarks:</h3>
|
||||
|
||||
<p>This program is formatted as the net for a tetrahedron. (hint, try feeding the
|
||||
program it’s own source code). When it runs there is an animation for the
|
||||
computation to work out the convex hull.</p>
|
||||
|
||||
<h2>Author’s comments:</h2>
|
||||
|
||||
<h3>Spec</h3>
|
||||
|
||||
<p>This is a convex polyhedron viewer, which:</p>
|
||||
|
||||
<ol>
|
||||
<li>reads three-dimentional vertices (3N float values) from stdin,</li>
|
||||
<li>calculates a convex hull of them, and</li>
|
||||
<li>renders it.</li>
|
||||
</ol>
|
||||
|
||||
|
||||
<p>This simple spec involves many details.</p>
|
||||
|
||||
<ul>
|
||||
<li>3D convex hull calculation
|
||||
|
||||
<ul>
|
||||
<li>recursive gift wrapping algorithm</li>
|
||||
<li>automatical merging of (almost) co-planar faces
|
||||
(i.e., faces are not triangulated)</li>
|
||||
<li>random perturbation for robustness</li>
|
||||
</ul>
|
||||
</li>
|
||||
<li>3D rendering
|
||||
|
||||
<ul>
|
||||
<li>perspective projection</li>
|
||||
<li>ASCII line drawing: <code>"',;;;,;'"</code></li>
|
||||
<li>camera in a spherical spiral orbit</li>
|
||||
</ul>
|
||||
</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p>(Note that this program does not use <code>math.h</code>.)</p>
|
||||
|
||||
<h3>Portability</h3>
|
||||
|
||||
<p>I think it conforms with both C89 and C99.
|
||||
I confirmed that it worked on gcc, clang, and tcc.
|
||||
It should not be warned with -pedantic and -Wextra.</p>
|
||||
|
||||
<h3>Tips</h3>
|
||||
|
||||
<p>You may want to use <code>tput</code> to hide a terminal cursor.</p>
|
||||
|
||||
<pre><code>tput civis
|
||||
./endoh4 < cube.txt
|
||||
tput cnorm
|
||||
</code></pre>
|
||||
|
||||
<h3>Bonuses</h3>
|
||||
|
||||
<p>You can change the screen size. Let the aspect ratio be about 3:1.</p>
|
||||
|
||||
<pre><code>gcc -DS=120,40 -o endoh4 endoh4.c
|
||||
</code></pre>
|
||||
|
||||
<p>The shape of this code is the geometric net of a regular tetrahedron.
|
||||
So, try:</p>
|
||||
|
||||
<pre><code>./endoh4 < endoh4.c
|
||||
</code></pre>
|
||||
|
||||

## Judges' comments:
|
||||
### To build:
|
||||
|
||||
make endoh4
|
||||
|
||||
### To run:
|
||||
|
||||
./endoh4
|
||||
|
||||
### Try:
|
||||
|
||||
NOTE: The author recommends the use of xterm.
|
||||
|
||||
./endoh4 < cube.txt
|
||||
|
||||
For example, if you are a soccer fan, try:
|
||||
|
||||
make all
|
||||
./endoh4 < solids/archimedian-solid/a11-truncated-icosahedron.txt
|
||||
|
||||
### Selected Judges Remarks:
|
||||
|
||||
This program is formatted as the net for a tetrahedron. (hint, try feeding the
|
||||
program it's own source code). When it runs there is an animation for the
|
||||
computation to work out the convex hull.
|
||||
|
||||
## Author's comments:
|
||||
### Spec
|
||||
|
||||
This is a convex polyhedron viewer, which:
|
||||
|
||||
1. reads three-dimentional vertices (3N float values) from stdin,
|
||||
2. calculates a convex hull of them, and
|
||||
3. renders it.
|
||||
|
||||
This simple spec involves many details.
|
||||
|
||||
* 3D convex hull calculation
|
||||
* recursive gift wrapping algorithm
|
||||
* automatical merging of (almost) co-planar faces
|
||||
(i.e., faces are not triangulated)
|
||||
* random perturbation for robustness
|
||||
* 3D rendering
|
||||
* perspective projection
|
||||
* ASCII line drawing: `"',;;;,;'"`
|
||||
* camera in a spherical spiral orbit
|
||||
|
||||
(Note that this program does not use `math.h`.)
|
||||
|
||||
### Portability
|
||||
|
||||
I think it conforms with both C89 and C99.
|
||||
I confirmed that it worked on gcc, clang, and tcc.
|
||||
It should not be warned with -pedantic and -Wextra.
|
||||
|
||||
### Tips
|
||||
|
||||
You may want to use `tput` to hide a terminal cursor.
|
||||
|
||||
tput civis
|
||||
./endoh4 < cube.txt
|
||||
tput cnorm
|
||||
|
||||
### Bonuses
|
||||
|
||||
You can change the screen size. Let the aspect ratio be about 3:1.
|
||||
|
||||
gcc -DS=120,40 -o endoh4 endoh4.c
|
||||
|
||||
The shape of this code is the geometric net of a regular tetrahedron.
|
||||
So, try:
|
||||
|
||||
./endoh4 < endoh4.c
|
||||
|
||||
