ce78d9d12c Introduces buffer alignment when writing to textures.
To avoid cross-boundary writes and hopefully to eke out a little better performance.
2017-10-17 22:09:48 -04:00
Thomas Harte
edbc60a3fb Various undefined behaviour fixes.
Primarily around uninitialised variables, but also with an attempted use of a negative pointer.

c6e6c3fcfb Resolves all current analyser warnings. 2017-08-24 22:18:44 -04:00
Thomas Harte
2d81acb82e Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14. 2017-08-11 19:18:45 -04:00
Thomas Harte
62eadbb51a Adjusted gamma ratio to be the correct way around. The PAL midrange should be slightly darker now. 2017-08-10 15:36:27 -04:00
Thomas Harte
ad8c8166bc Built in gamma conversion for all machines, assuming an output of 2.8 for PAL, 2.2 for NTSC. 2017-08-10 15:17:08 -04:00

55fd9122d0 Slightly relaxed vertical sync testing. 2017-07-30 21:19:42 -04:00
Thomas Harte
0bf4fdc9af Simplified slightly. 2017-07-29 21:37:59 -04:00
Thomas Harte
ed8c73eb14 Ensured lengthy constant sync can't appear to be two sync pulses, regardless of other interruption. 2017-07-29 18:25:04 -04:00
Thomas Harte
3528a7f78b Made an attempt at triggering vertical sync the expected number of time after it begins, regardless of total length. 2017-07-29 17:33:52 -04:00
Thomas Harte
54bcc40192 With an eye towards being more accurate as to vertical sync recognition: acknowledged that the detection period varies between PAL and NTSC. 2017-07-29 14:53:53 -04:00
Thomas Harte
be750ee427 Eliminated all dangling implicit signedness conversions. 2017-07-21 21:52:37 -04:00
Thomas Harte
449c33ee8b Signedness fixes. 2017-07-21 21:28:04 -04:00

ef03c84b21 More definitively removed the old sample-offset blending approach to filtering. 2017-07-21 20:58:55 -04:00
Thomas Harte
5b4c5b0cbf Avoided having two different variables named next_output_run. 2017-07-21 20:46:08 -04:00
Thomas Harte
8ccec37a4b Eliminated a further potential cause of texture/geometry mismatch: the texture retain succeeded but then there wasn't room for geometry. 2017-07-09 19:11:38 -04:00
Thomas Harte
a25c2fd6b5 Got more explicit about what the thinking is here re: multiple sources of action. 2017-07-09 17:54:26 -04:00
Thomas Harte
ee1a9a4781 Eliminates attempts cleverly to shuffle unsubmitted runs, because no mechanism exists to stop them overwriting previously-submitted-but-not-yet-flushed runs. Which implies that the buffer must be fully circular. The cost of which is sometimes having to make two calls to glTexSubImage2D. Also added some TODOs, and a means for reporting when a retain_latest is ineffective, in which situation it would be inappropriate to attempt to generate correlated geometry 2017-07-09 17:50:22 -04:00
Thomas Harte
2f90f35478 Ensured the same write area can be submitted multiple times — this is actively used if a run of data overlaps a flywheel-suggested sync. Which nullifies the idea of not having a write area in the barrel, at least as soon as any one has been allocated. 2017-07-07 23:37:44 -04:00
Thomas Harte
12f7e1b804 Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE. 2017-07-07 23:35:14 -04:00
Thomas Harte
c7fa2ed11a It makes more sense not to retain the previous texture builder run until vertex storage is confirmed. 2017-07-07 23:21:25 -04:00
Thomas Harte
bfbe12b94b Made an attempt further to tie geometry and texture generation fully together, removing the assumption that the caller will achieve one-to-one calling. 2017-07-07 22:25:05 -04:00
Thomas Harte
ab1374f801 Added an assert on an assumed buffer size alignment. 2017-07-06 21:46:24 -04:00
Thomas Harte
344d267fd2 Introduced sharper chrominance for genuinely black-and-white signals. 2017-07-06 21:38:33 -04:00
Thomas Harte
4211389ac7 Connected machine-supplied colour burst amplitude to shader, discarding hard-coded value. Net effect: the colour component is now discarded for the ZX80 and 81. 2017-07-06 21:29:08 -04:00
Thomas Harte
c6d00ec7d1 Switched phase and amplitude varying to a 3d vector; the third component is 1/amplitude if amplitude is non-zero, and zero otherwise. So you can multiply by that to get chrominance, rather than dividing by amplitude. With the direct effect that detected chrominance should automatically be zero if the colour burst didn't exist (i.e. had zero amplitude). 2017-07-06 21:25:38 -04:00
Thomas Harte
a5075d9eb5 Formalised the reasoning behind the colour phase fix-up and made it an opt-in per-caller value. Only the Oric currently needs to opt in. 2017-05-16 20:31:39 -04:00
Thomas Harte
c2b5a9bb1f Minor fix: given that phase is now a function of position, stop nudging position. 2017-05-13 21:50:48 -04:00
Thomas Harte
b14c892740 Switched to a safer RAII approach to this lock. 2017-05-10 21:29:39 -04:00
Thomas Harte
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00
Thomas Harte
e63229a5e5 Pulled vertical sync detection entirely outside the loop, and gave it greater perspective. 2017-03-06 19:15:33 -05:00
Thomas Harte
ad73379d1c Took vertical sync detection logic entirely out of the loop. 2017-03-05 20:17:55 -05:00
Thomas Harte
4751615623 Fixed NTSC colour cycle count, and hence the 2600's reported line lengths and phase offset. 2017-03-04 17:31:39 -05:00
Thomas Harte
a3fcd15980 Loosened sync charge level requirement. 2017-03-01 22:16:56 -05:00
Thomas Harte
d19f26887d Performed a very naive shuffling of output builder sets onto the OpenGL queue. Which makes the frequency switcher work properly from it's possibly-contextless thread. 2017-02-20 10:39:31 -05:00
Thomas Harte
6cb95b4fc5 Switched to passing around std::strings rather than char *s, because they should be easier to capture. 2017-02-20 10:35:33 -05:00
