6f7dd10d95
Reduces draw/update contention.
...
This won't yet have any effect on either port owing to the way they handle contexts, but here it is.
2019-03-07 19:28:32 -05:00
24fb95291a
Reverts to support a full RGBA colour buffer.
2019-03-07 19:22:40 -05:00

Experimentally introduces adaptive quality intermediate buffers.
2019-03-05 21:41:20 -05:00
86a6b04d4a
Begins attempts to keep track of display metrics.
...
i.e. a system that can both make smart decisions about when to use a lower resolution, and hopefully allow some sort of flywheel-esque horizontal retrace synchronisation. And possibly some raster beam chasing?
2019-03-04 21:54:50 -05:00
641e349f33
Switches to an 8bpp stencil, for Nvidia compatibility.
2019-03-03 20:38:24 -05:00

Ensures draw is a no-op prior to pipeline setup.
2019-03-03 15:04:14 -05:00
bee0d09877
Splits display update and draw functions.
...
On the Mac, draw is now called without an update for resizing events, and
anything else requested by AppKit. In all other cases — including from
the SDL version — both are called as if they were still a single function.
2019-03-02 19:33:28 -05:00
d122535a65
Unifies the OpenGL screenshot code and corrects it for arbitrary alignment.
2019-02-27 21:05:02 -05:00
6b4f6971de
Disables upper limit on frame buffer size.
...
Filtering is sufficiently imperfect as to make this justifiable only when performance requires it. So I need a test for that. Marked as TODO.
2019-02-26 22:39:07 -05:00
79707a3c66

2019-02-26 22:35:55 -05:00

...
Thereby revealing some sort of error in offset selection.

7bb90c78d9
Resolves out-of-bounds initial condition whenever this loop began with start_line = 2047.
...
This, I believe, was the remaining cause of screen flashes.
2019-02-24 19:50:19 -05:00
a6e61ef83b
Reverts the clear colour to black.
...
The change was related to debugging; it was not intentionally committed.
2019-02-24 14:36:08 -05:00
c775a6c0f8
Introduces but disables a couple of bits of logging that might be helpful again in the future.
2019-02-24 14:30:39 -05:00
2f491b5be1
Reintroduces fragment snapping for composite colour sampling.
...
Thereby uncovers some sort of slightly-off recording of scan lines. On the Apple II, individual scans reach the ScanTarget at a density of exactly 0.25 colour cycles per pixel. So that timing information propagates exactly. But the whole lines that are composed via ::announce end up trying to fit 0.250154 colour cycles per pixel. Which creates a phase error as the display progresses from left to right.
This will need to be resolved in order to be able to fix the Apple II's intended colour phase. But, also, it's probably what was wrong with the Oric. And, quite possibly, why the single-step shader didn't work.
2019-02-24 13:39:14 -05:00
de7ebead23
Ensures the line_allocation_has_failed_ condition can be exited.

Fixed: the two shaders that use a common input array should use common bindings.
2019-02-10 22:39:24 -05:00
