fix issue where ftenq protocol positions were sticking. fixed manifest file windowless infinite wait. Added support for ^[\img\foo^] images on the console if they are at the start of the line. Console objects may now be drawn by csqc. Key input is blocked for now, lest csqc get access to things its not allowed to access. Will add provisions later. fixed sound menu crash. added ultrawide speex codec. clamp micamp levels to try to boost audio quality/audiability. rtp control plugins are now allowed to use opus, speex support is correctly queried instead of assumed. WriteFloat now works properly, and not just for ents. no longer sending prespawn/precaches/signon commands to clients that do not expect them. fix sql column header queries. more verbose about active nq protocol verions. -condebug overrides config. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4461 fc73d0e0-1445-4013-8a0c-d673dee63da5

info about bloom algo:
|
|
bloom is basically smudging.
|
|
screen is nearest-downsampled to some usable scale and filtered to remove low-value light (this is what stops non-bright stuff from blooming)
|
|
this filtered image is then downsized multiple times
|
|
the downsized image is then blured
|
|
the downsized images are then blured horizontally, and then vertically.
|
|
final pass simply adds each blured level to the original image.
|
|
all samples are then added together for final rendering (with some kind of tone mapping if you want proper hdr).
|
|
|
|
note: the horizontal/vertical bluring is a guassian filter
|
|
note: bloom comes from the fact that the most downsampled image doesn't have too many pixels. the pixels that it does have are spread over a large area.
|
|
|
|
http://prideout.net/archive/bloom/ contains some sample code
|
