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.

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

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.

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.

Made an attempt to simplify in-shader phase calculation, now that output position is a direct multiple of phase.

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

Switched off filtering, at least temporarily, to try to ensure that sampling is all where it should be.

Started taking steps towards using a texture barrier where possible to reduce all of my framebuffer binds. Some output appears, but it's not correct.

Definitively eliminated the additional y filtering step; if I'm going to work to ensure always four samples per colour cycle, I can put the channel separation coefficients directly into their shaders, cutting down on samples.

Temporarily disabled composite processing to show the pure stream. Fixed both automatic calculations of phase — per line and, at input, per pixel.

Fixed: colour_cycle_numerator_ doesn't need to be multiplied by the time multiplier because it'll get that for free from the calculation of next_run_length.

Experimental: up the chroma accuracy, just let the luma go straight through. Subject to figuring out how I'm still losing so much precision.

Restored proper colour separation, but somewhere a massive hit in horizontal resolution is happening — much greater than one would expect from the sample size picked. So investigation to come.
2017-01-03 22:32:07 -05:00
Thomas Harte
7d60df9075
Added the option for both intermediate and output shaders to use only a portion of the input/output texture; made an attempt to pick an appropriate proportion in order to align signal sampling with the colour subcarrier.

Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.

Made an attempt to shuffle the texture builder to a similar flush/submit pattern as the input builder. Don't care about thread safety yet, as it's obvious I'm going to need to move that back up to the CRT.
2016-12-06 07:24:07 -05:00

Started introducing an extra layer of indirection so as to be able to bind the texture builder to the same flush and submit patern as the array builder.

Moved underscores, removed indirections where they're not necessary, converted those names that were still looking very Objective-C and moved the GL fence variable into the private area, where it should always have been.
