6547560e52 Gives the CRT the ability to move iCoordinate multiplication outside of the fragment loop.
That resolves precision issues, as were plaguing the Apple II.

70039d22f1 Allows a CRT machine owner to set the target frame buffer for OpenGL output, breaking the assumption that it'll be zero. 2017-11-12 19:29:22 -05:00

2e15fab651 Doubles down on <cX> over <X.h> for C includes, and usage of the namespace for those types and functions. 2017-11-11 15:28:40 -05:00
Thomas Harte

ce78d9d12c Introduces buffer alignment when writing to textures.
To avoid cross-boundary writes and hopefully to eke out a little better performance.

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
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
be750ee427 Eliminated all dangling implicit signedness conversions. 2017-07-21 21:52:37 -04:00

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
a5075d9eb5 Formalised the reasoning behind the colour phase fix-up and made it an opt-in per-caller value. Only the Oric currently needs to opt in. 2017-05-16 20:31:39 -04:00
Thomas Harte
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00
Thomas Harte
e63229a5e5 Pulled vertical sync detection entirely outside the loop, and gave it greater perspective. 2017-03-06 19:15:33 -05:00
Thomas Harte
ad73379d1c Took vertical sync detection logic entirely out of the loop. 2017-03-05 20:17:55 -05:00

d19f26887d Performed a very naive shuffling of output builder sets onto the OpenGL queue. Which makes the frequency switcher work properly from it's possibly-contextless thread. 2017-02-20 10:39:31 -05:00
Thomas Harte
6cb95b4fc5 Switched to passing around std::strings rather than char *s, because they should be easier to capture. 2017-02-20 10:35:33 -05:00
Thomas Harte
d979a822ac Introduced a deferred task list for the OpenGL thread. 2017-02-19 21:46:07 -05:00
Thomas Harte
d0a93409e6 Made an attempt to simplify in-shader phase calculation, now that output position is a direct multiple of phase. 2017-01-11 08:18:00 -05:00
Thomas Harte
a549fd1ecc 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. 2016-12-10 13:42:34 -05:00
Thomas Harte
5216dda675 Added some brief extra exposition to the texture builder, cut all internal tex_x/y and source_divider stuff from the CRT. 2016-12-06 19:08:55 -05:00
Thomas Harte
4ff33254e1 Sought to shift locking back up to the CRT. And to be a bit more RAII-ish. 2016-12-06 18:48:30 -05:00
Thomas Harte
1f91d29434 Progressed to usage of an array builder and a texture builder up to the point of a successful build. 2016-11-17 12:26:04 +08:00
Thomas Harte
0f3b02edb7 Switched to postfix underscores and gave this class ownership of a texture builder and an array builder, though it presently uses neither. 2016-11-17 11:00:11 +08:00
Thomas Harte
9ee11d7765 At the expense of API simplicity, at least for now, resolved the most glaring cause of dirty lines. 2016-11-16 11:34:05 +08:00

1f857c619b Fixed timing issues. Static box of frame achieved! 2016-10-12 21:42:36 -04:00
Thomas Harte
257420b0f7 Fixed potential output error if buffer top were hit; clarified buffer size constants. 2016-05-10 19:04:03 -04:00
Thomas Harte
8e4ab37719 Things are back pretty much to where they were, but offset is eliminated as an input. 2016-05-07 18:37:18 -04:00
Thomas Harte
87df57195d Started on an attempt not to treat the various buffers as free to loop within, starting with the input texture. 2016-05-04 07:39:45 -04:00
Thomas Harte
2541711061 Made attempts (i) to flush buffers before unmapping them; and (ii) to bring texture uploads within the new orthodoxy. 2016-05-03 20:56:47 -04:00
Thomas Harte
082003ed0a Reintroduced the CRT delegate and the 2600's automatic region switching. Albeit that the CRT itself doesn't adjust properly to new timings yet. 2016-04-24 18:36:22 -04:00
Thomas Harte
80a3169674 Started reviving the Atari 2600 emulation. Put new startup sequence into place. 2016-04-24 06:56:08 -04:00
Thomas Harte
4be8053ba9 Updated documentation. 2016-04-12 22:38:49 -04:00
Thomas Harte
7276a06cc0 Added a helper to calculate a visible rect based on output timings, used it to scale the Electron output up to the full window size. 2016-04-11 21:47:23 -04:00
Thomas Harte
aa8a192c7e Simplified API down to their being a single texture with a specified depth. 2016-03-19 17:37:55 -04:00
Thomas Harte
4ac1f959e9 A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything. 2016-03-19 17:07:05 -04:00
Thomas Harte
67dffc89e0 Stripped unnecessary includes. 2016-03-13 13:25:34 -04:00
Thomas Harte
7255408313 Experimented with going back to horizontal sync on leading edge; not sure so (temporarily?) disabled. 2016-03-08 22:54:05 -05:00
Thomas Harte
bf5747f83e Made an attempt to chop out all the stuff of building up the OpenGL data from the stuff of parsing input. 2016-03-08 22:40:23 -05:00
Thomas Harte
14b2927275 Made further attempts to tidy up; trying to demarcate between public interface and private. 2016-03-08 20:59:16 -05:00
Thomas Harte
c7976dd657 Started trying to clean up my Outputs namespace by moving stuff related to the CRT underneath a separate subnamespace. 2016-03-08 20:49:07 -05:00
