NAME
clip3d - Clips the polygon given in vtx using fixed point math. Allegro game programming library. SYNOPSIS
#include <allegro.h> int clip3d(int type, fixed min_z, fixed max_z, int vc, const V3D *vtx[], V3D *vout[], V3D *vtmp[], int out[]); DESCRIPTION
Fixed point version of clip3d_f(). This function should be used with caution, due to the limited precision of fixed point arithmetic and high chance of rounding errors: the floating point code is better for most situations. RETURN VALUE
polygon3d(3alleg4), clip3d_f(3alleg4) Allegro version 4.4.2 clip3d(3alleg4)

NAME
clip3d_f - Clips the polygon given in vtx using floating point math, Allegro game programming library. SYNOPSIS
#include <allegro.h> int clip3d_f(int type, float min_z, float max_z, int vc, const V3D_f *vtx[], V3D_f *vout[], V3D_f *vtmp[], int out[]); DESCRIPTION
Clips the polygon given in `vtx'. The number of vertices is `vc', the result goes in `vout', and `vtmp' and `out' are needed for internal purposes. The pointers in `vtx', `vout' and `vtmp' must point to valid V3D_f structures. As additional vertices may appear in the process of clipping, so the size of `vout', `vtmp' and `out' should be at least vc * (1.5 ^ n), where `n' is the number of clipping planes (5 or 6), and `^' denotes "to the power of". The frustum (viewing volume) is defined by -z<x<z, -z<y<z, 0<min_z<z<max_z. If max_z<=min_z, the z<max_z clipping is not done. As you can see, clipping is done in the camera space, with perspective in mind, so this routine should be called after you apply the camera matrix, but before the perspective projection. The routine will correctly interpolate u, v, and c in the vertex structure. However, no provision is made for high/truecolor GCOL. RETURN VALUE

## Shopt -s histappend

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file. # When the shell exits, append to the history file instead of overwriting it shopt -s histappend

## Undeletable file

Greetings, I'm trying to delete a file with a weird name from within Terminal on a Mac. It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘. Here are some examples of what I've tried: 12FX009:5 dpontius\$ ls ââWord FinderÂŽ Plusâ˘ 12FX009:5 dpontius\$ rm...
