makeIf you wish to change the size (see the Author’s remarks
below) you can do so with the SIZE variable. For instance you can do:
make clobber SIZE=50,50 allbut you can also do this directly with the endoh4.sh script as described below.
The current status of this entry is:
STATUS: INABIAF - please **DO NOT** fixFor more detailed information see 2013 endoh4 bugs.
./endoh4 < file
./endoh4.sh fileThe second form is preferable as it will temporarily make the cursor invisible
as recommended by the author. If no file is specified in the ./endoh4.sh command
line it will feed to the program endoh4.c.
./endoh4.sh cube.txtHit ctrl-c to end the program.
The author recommends the use of xterm.
For an example, if you are a football/soccer fan, try:
./endoh4.sh solids/archimedian-solid/a11-truncated-icosahedron.txtYou can provide more than one file:
./endoh4.sh solids/archimedian-solid/a11-truncated-icosahedron.txt cube.txtHit ctrl-c/intr to go to the next file.
If you wish to change the size to 50,50 without passing any arg:
SIZE=50,50 ./endoh4.shNot specifying a file feeds endoh4.c to the program.
This program is formatted as the net for a tetrahedron (hint: try feeding the
program it’s own source code like ./endoh4.sh). When it runs there is an
animation for the computation to work out the convex hull.
This is a convex polyhedron viewer, which:
stdin,This simple spec involves many details.
"',;;;,;'"(Note that this program does not use math.h.)
I think it conforms with both C89 and C99. I confirmed that it worked on gcc,
clang, and tcc. It should not trigger warnings with -pedantic and -Wextra.
You may want to use tput to hide the terminal cursor.
tput civis
./endoh4 < cube.txt
tput cnormor
./endoh4.sh cube.txtYou can change the screen size. Let the aspect ratio be about 3:1.
cc -DS=120,40 -o endoh4 endoh4.cThe shape of this code is the geometric net of a regular tetrahedron. So, try:
./endoh4 < endoh4.c # or ./endoh4.shThe solids/ directory includes various solid data:
