940e9e037e Adds first_scan to LineMetadata.
Also reorders `Line` fields to match `Scan` fields, just for visual consistency.

512c0079a9 Makes thread safe. 2020-08-15 21:52:55 -04:00
Thomas Harte
645c29f853 Adds an intermediate buffer to correct inter-frame smoothing.
Also goes someway back to the old scan output scheduling, albeit presently with limited thread safety.

7ac88536dd Respects machine aspect ratio.
To an extent. Doesn't currently deal with cropping of machines when the window aspect ratio is smaller.

230b9fc9e6 Permits multiple simultaneous scan reading ranges.
Also updates the OpenGL scan target as per the latest movements of things.

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.

a136a00a2f Takes a shot at adding RGB -> S-Video and composite conversion, for all RGB types. 2020-08-11 22:11:50 -04:00
Thomas Harte
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.

28d933d5d6 Does just enough to get 8-bit RGB and 1-bit luminance machines to display.
Assuming an 'RGB' output.

93c6105442 Corrects calculation of dirty texture area. 2020-08-09 20:45:14 -04:00

57fecdc09e Ties everything together in an attempt to display RGB scans.
I'm actually just getting a mess of pixels, but it's something!

f16ad8f71d Takes a shot at submitting texture changes. 2020-08-09 17:59:52 -04:00

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.

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.

edf41b06fd Eliminates the quad buffer.
Vertices can be adduced from vertex ID.

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?

fbda7aab23 Does just enough to get the correct (aspect ratio aside) output of scan outlines.
So, up next, can I start streaming these things?

c575aa0640 Adds a buffer for scans, and posts two test instances. 2020-08-07 22:03:54 -04:00
Thomas Harte
4421acef34 Gets some uniforms in on the action.
With some effort towards scans, but incompletely so.

219923bd63 Reduces vertex size, draws a quad. 2020-08-05 21:33:25 -04:00
Thomas Harte
7551782a25 Switches to interleaved vertex data.
This more closely relates to what I actually want to do.

72df6e52cd This is possibly at least dispatching an empty command buffer correctly. 2020-08-04 19:44:56 -04:00

e235a45abb Breaks all output.
... by switching out NSOpenGLView for MKLView with no drawing infrastructure yet in place.
