This separate the FOV calculations from other refdef calcs, cleaning up the
renderer proper and making it easier for other parts of the engine (eg,
csqc) to update the fov.
The server edict arrays are now stored outside of progs memory, only the
entity data itself (ie data accessible to progs via ent.fld) is stored in
progs memory. Many of the changes were due to code accessing edicts and
entity fields directly rather than through the provided macros.
set_bits_t is now 64 bits for x86_64 machines (in linux, anyway). This gave
qfvis a huge speed boost: from ~815s to ~720s.
Also, expose some of the set internals so custom set operators can be
created.
Now we can get tight (<1e-6 * radius_squared error) bounding spheres. More
importantly (for qfvis, anyway) very quickly: 1.7Mspheres/second for a 5
point cloud on my 2.33GHz Core 2 :)
It "works" for lines, triangles and tetrahedrons. For lines and triangles,
it gives the barycentric coordinates of the perpendicular projection of the
point onto to features. Only tetrahedrons are guaranteed to reproduce the
original point.
Rather than prefixing free_ to the supplied name, suffix _freelist to the
supplied name. The biggest advantage of this is it allows the free-list to
be a structure member. It also cleans up the name-space a little.
I'd forgotten that ED_ConvertToPlist mangled light into light_lev and
single component angle values into a vector. This fixes much of the
breakage in qflight (but not the light levels)
Sys_LongTime returns time in microseconds as a 64-bit int. Sys_DoubleTime
uses Sys_LongTime, converts to double and offsets 0 time by 4G (2**32).
This gives us consistent sub-microsecond precision for a very long time.
See http://randomascii.wordpress.com/2012/02/13/dont-store-that-in-a-float/
Once and for all: remove the default and move the Sys_Error outside the
switch (changing appropriate breaks to returns). Now gcc will let me know
when I forget to update the switch statements.
I'd missed a set of bit->lightnum conversions that resulting in lightnum
becoming much greater than 128 and thus trashing memory when the surface
was marked.
This give much better control over individual joystick axes. They now have
per-axis pre and post amplification, the linear controller mappings are
more intuitive, and axes can now bet setup as buttons using thresholds.
Many thanks to Johnny on Flame for his work on the "user interface".
Johnny's number->J_AXISn mapping is preserved, but I had intended for any
key to be supported (J_AXISn was just to ensure free keys were available).
This gives both methods (and some range checking on the axis button
number).
First, this completely smashes joystick input: it will not work (though it
doesn't crash). This is because there is, as of yet, no means to configure
the system.
Each joystick axis has:
- per-axis amplification (both pre and post).
- per-axis offset (offset applied after pre-amp but before post amp)
- selectable destination:
- linear delta: position and angles (as before)
- axis button: if the value crosses the threshold, the given key is
pressed or released as appropriate.
The axis amplification still uses joy_amp and joy_pre_amp (and
in_amp/in_pre_amp), but now also has the per-axis settings.
The per-axis offset is most useful for axis buttons. For example, the xbox
360 controller triggers are analong but go "all the way to negative on 0
state". Offsetting the input keeps axis button thresholds simple.
Amplification and offset is applied before anything is done with the axis
value. The formula is:
joy_amp * in_amp * axis-amp *
(offset + value * joy_pre_amp * in_pre_amp * axis-pre_amp)
Axis button thresholds are very simple: if the sign of the value is the
same as the sign of the threshold and abs(value) >= abs(threshold), the
button is pressed. While multiple thresholds and keys can be placed on an
axis, only one can be pressed at a time. The threshold furthest from 0
wins.
The ~ gets expanded to CSIDL_LOCAL_APPDATA, $HOME, $USERPROFILE or just
".", whichever succeeds first. The usual location will be:
"C:\windows\profiles\<user>\Local Settings\Application Data".
"." is now the fallback for *nix systems too.
