67ca298a72 Forces a no-op compute shader into the S-Video pipeline. 
The intention is to restrict the area acted over, and to do the S-Video filtering in there. Then I'll just need two such stages for composite.

67d4dbf91a Starts girding for a third pipeline. 2020-08-31 20:01:59 -04:00

b344269140 I think I accept the need for intermediate steps now. 
This allocates storage.

bb547610f2 Adds commentary, shrinks some intermediate texture sizes. 2020-08-30 12:06:29 -04:00

1e1f007bb7 Possibly convinces myself that no-separation chroma/luma isn't practical. 
... as appealing as it may be, were filters perfect.

c40d858f02 Switches back to angular stuff at input resolution; ensures all S-Video modes work. 
Now to roll back onto composite. Fingers crossed!

3d564d85fd Proves that per-pixel sine/cos evaluation avoids phase issues. 
Even in PAL mode. But I'd rather not _require_ this as it kind of negates directly-sampled input.

02cea40ffa Attempts to avoid introducing phase error in scanToComposition. 
Also brightens S-Video up to RGB levels.

7ca0362f23 Treads water. 
Difficult current question: why does the Atari 2600's display change colours as the display tries to achieve horizontal lock? Phase should be unchanged. Ergo something is amiss.

ad6fb85fda Corrects use of composition buffer. 
Something is still very obviously amiss in colour processing somewhere down the line, but the correct forms are once again visibly in evidence.
 2020-08-20 20:21:28 -04:00
Thomas Harte
5dc39a5d24 Adds the composition render pass.

7ac88536dd Respects machine aspect ratio. 
To an extent. Doesn't currently deal with cropping of machines when the window aspect ratio is smaller.
 2020-08-14 21:24:25 -04:00
Thomas Harte
230b9fc9e6 Permits multiple simultaneous scan reading ranges. 
Also updates the OpenGL scan target as per the latest movements of things.
 2020-08-12 22:08:41 -04:00
Thomas Harte
27ca782cac Enables blending; attempts to enable frame preservation. 
The latter seems to be evidencing a double buffer at play. More investigation required.

On the plus side, the direct route is still well within GPU budget at 4k on my Core M. So a huge improvement there.

Thomas Harte
8374a5e579 Adds superficially correct compositeSampleLuminance8Phase8 function. 
Thereby uncovering a minor error in my decoding of colour phase.
 2020-08-10 21:33:59 -04:00

525233e10b Ensures all input data types are parseable in Metal. 
Though now I need to think a bit more about the best way to compose signal-type conversions, and whether output-type calculations (i.e. gamma, brightness) are applied.

f16ad8f71d Takes a shot at submitting texture changes. 2020-08-09 17:59:52 -04:00
Thomas Harte
e340685a99 Seemingly proves that proper geometry is reaching Metal by drawing scans. 
No in-buffer accumulation yet, but this is progress. If I can add accumulation and stencil clearing, I'm not doing badly.
 2020-08-08 23:11:44 -04:00
Thomas Harte
df89a8771c Makes an attempt to have the emulator fill the actual GPU buffers. 
Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.
 2020-08-08 22:49:02 -04:00
Thomas Harte
bdcf266e45 Having learnt a bit more: eliminates Metal attribute tags, switches to more natural expression of structs. 
Also thereby eliminates the need for a forced alignas(4) on various structs.

38960a08d6 Adds adjustment for display aspect ratio. 
While also realising that I appear to be getting away without an MTLVertexDescriptor for Scans. Maybe OpenGL has prejudiced me, and they're actually optional for interleaved data?
 2020-08-07 22:29:24 -04:00
Thomas Harte
fbda7aab23 Does just enough to get the correct (aspect ratio aside) output of scan outlines. 
So, up next, can I start streaming these things?

Thomas Harte
405e9e7c68 Shunts audio into its own QThread. 
For the record, this was the first means I found of attempting that which actually seemed to work. A plain QThread, with something `connect`ed to its `started` signal didn't seem to work (perhaps `connect` is smart at thread confinement?), `moveToThread` didn't work on the audio output after the fact, etc.

5f13ee7c19 Simplifies AudioBuffer by consolidating logic into writes. 
This is kind of fiddling in the margins though; I'm having a lot of difficulty determining the semantically-correct way to get Qt not to funnel all activity through a single thread.
 2020-06-09 23:56:08 -04:00
Thomas Harte
d9f02aecdf Adds an additional buffer. To reduce latency. No, really. 
Specifically: there's no way to guarantee no overbuffering due to the startup race, other than having QAudioOutput obtain data by pull rather than push. But if it's pulling then that implies an extra buffer. And since the sizes it may pull are not explicit, there's guesswork involved there.

So: no extra buffer => uncontrollable risk of over-buffering. Extra buffer => a controllable risk of over-buffering.

b76a5870b3 Moves drawing into the next timer tick after retrace if sync locked. 
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.

This should completely eliminate tearing for machines that can be synced to the native output rate.
