373820f080 Attempts to establish interface to decouple scan output from generation. 
Restores some functionality that had dropped out in the interim: diagonal scans, decoupling of scan scaling from timing of the composite subcarrier.

a38639d099 Eliminates the concept of an iCoordinate.

Thomas Harte
0c65385c82 Undoes older interpretation of alternating phase. 
I now understand, hopefully, that it's only the phase of the second colour component that alternates. That has the pointwise effect of reversing the colour signal. Hence the effect of phase errors cancelling themselves out up on successive lines up to a point.

Thomas Harte
23c34a8c14 Corrects calculation of intermediate buffer width multiplier. 
Specifically: I had failed to factor in that the multiplied-up input frequency might be less than than the full width of the bitmap.

The Atari and MSX in particular now look much better.
 2018-01-15 16:52:40 -05:00
Thomas Harte
93ece2aec7 "Doubles" the bandwidth given to composite signals.

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

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
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
