Thomas Harte
ce78d9d12c Introduces buffer alignment when writing to textures.
To avoid cross-boundary writes and hopefully to eke out a little better performance.

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
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

ef03c84b21 More definitively removed the old sample-offset blending approach to filtering. 2017-07-21 20:58:55 -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

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
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
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
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
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
Thomas Harte
fccdce65b9 Switched to lock guards. 2017-02-19 21:45:28 -05:00
Thomas Harte
97cdfea9e9 Resolved spurious static analyser complaint: input_size and output_size aren't supposed to have defined values if input or output is null. But whatever. 2017-02-11 13:36:09 -05:00
Thomas Harte
23f3ccd77a Made a further attempt to prevent overwrites. 2017-02-05 17:47:34 -05:00
Thomas Harte
ebde955356 This needs to be a memmove as the areas may overlap. 2017-01-29 16:12:48 -05:00
Thomas Harte
7fd02e7f4c Added an extra flag to avoid potential race condition on is_full_, being reset from the background despite a write area not having been allocated. 2017-01-29 16:11:29 -05:00
Thomas Harte
c2d7e36c8f Ensured logic for whether composite output is in use is consistent. 2017-01-25 21:25:03 -05:00
Thomas Harte
5761c8267b [Re-]Eliminated connection between colour subcarrier frequency and monitor output mode. 2017-01-24 20:48:54 -05:00
Thomas Harte
b4159295f6 Switched to using quads for intermediate draws. The specific concern is the flexibility offered in the GL spec as to line drawing algorithms. And even if a driver implements exactly to spec then it should omit the final pixel. 2017-01-11 21:18:41 -05:00
Thomas Harte
d0a93409e6 Made an attempt to simplify in-shader phase calculation, now that output position is a direct multiple of phase. 2017-01-11 08:18:00 -05:00
Thomas Harte
4c3669f210 Reduced precision of input phase, but I'm not necessarily persuaded by it as a move. However it's clear that something is off in that whole area. But if phase is locked by output position, do I need to retain this level of complexity? Also ensured that intermediate buffers prior to the final are sampled using the nearest sampling mode, also to reduce precision errors. 2017-01-10 22:08:07 -05:00
Thomas Harte
eeb646868b Switched off filtering, at least temporarily, to try to ensure that sampling is all where it should be. 2017-01-08 19:53:08 -05:00
Thomas Harte
3d789732a2 Switched back to full buffer clearing. Until I can figure out the source of noise. 2017-01-08 19:50:31 -05:00
