11073daee1 Issues appear to be around timing generally. Working on it. 2016-06-02 20:15:48 -04:00
Thomas Harte
40600b4bcb Made sprite placement consistent at least. Not necessarily yet correct. 2016-05-18 22:07:24 -04:00
Thomas Harte
3765c5fbb5 Fixed error that would prevent an interrupting frame from ever being drawn. 2016-05-18 21:45:35 -04:00
Thomas Harte
ddfc9910e5 Sought to draw in a standard serial arrangement as and when bandwidth allows it. 2016-05-09 07:17:12 -04:00
Thomas Harte
9c89b668ae Made further attempts to improve synchronisation and interrelated timing between display and machine update. 2016-04-20 22:35:46 -04:00
Thomas Harte
104f44f27f Attempted to improve deinterlacing, gave the CRT full control over blend mode, switched back to 2000000Mhz audio. 2016-04-14 22:20:47 -04:00
Thomas Harte
fd1f6a7e1f Expanded on thinking. 2016-04-06 19:35:53 -04:00

e885438363 The penny has finally dropped that I can drive the CPU stuff in a manner completely decoupled from the GPU stuff. For much improved parallelisation. 2016-04-06 19:34:34 -04:00
Thomas Harte
4595741ab0 Made an attempt not to interrupt the display link queue too much when emulation is running slowly. 2016-04-04 20:22:33 -04:00
Thomas Harte
902017a962 Fixes: drop any processing backlog, try not to allow an Electron document to close mid-draw, perform a frame grab even if the emulated machine is over-processing, really really don't create a CRT until it's safe. 2016-03-20 18:42:37 -04:00
Thomas Harte
eabc382540 Fixed: of course I can't rely on the pointer to CVTimeStamp not becoming dangling during a queue jump. 2016-03-19 23:02:42 -04:00
Thomas Harte
4c5d66c317 Made sure GL context isn't activated until it's locked. 2016-03-19 22:54:56 -04:00
Thomas Harte
a546277f88 Added the simplest mechanism to decouple emulation from the display link queue. 2016-03-19 22:53:37 -04:00
Thomas Harte
9da7716c72 Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow. 2016-03-19 22:46:17 -04:00
Thomas Harte
bb0cd89574 Got explicit about threading guarantees. 2016-03-13 13:38:03 -04:00
Thomas Harte
41c09f8c3f Renamed CSCathodeRayView to CSOpenGLView as it no longer has any CRT-related responsibilities. It just does the GL and manages a serial dispatch queue. 2016-03-05 14:45:09 -05:00
Thomas Harte
95efeb1d56 Ensured all delegate and responder delegate messages occur on the same queue. 2016-03-05 14:35:47 -05:00
Thomas Harte
c754a6e45a Decoupled execution speed and frame rate; cleaned up. 2016-03-03 22:12:31 -05:00
Thomas Harte
60d35fa72b Requested multisampling, if available, rather than supersampling. 2016-02-27 22:46:31 -05:00
Thomas Harte
c7f54d649e Switched back down to two samples per pixel. Though one might do it. Need to investigate. 2016-02-18 23:21:25 -05:00
Thomas Harte
a01f90ff3e Attempted a switch to the real PAL visible area and to something a bit like a real phosphor decay. 2016-02-14 21:57:23 -05:00
Thomas Harte
d3d505b7bc That's one header file less. 2016-02-05 23:05:58 -05:00
Thomas Harte
6ab425deda There is now a semi-reasonable amount of screen output again. 2016-02-05 21:35:39 -05:00
Thomas Harte
80e7e5e602 Updated to return old behaviour of drawing only upon changes. 2016-02-04 23:05:47 -05:00
Thomas Harte
8bc3f8046d This endeavours to move everything into the CRT class except the final version of shader building. 2016-02-04 22:57:46 -05:00
Thomas Harte
e0d51408e4 Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT. 2016-02-04 22:28:50 -05:00
Thomas Harte
4554abb755 Made an attempt to be more rigorous in display generation on the Electron, to make sure I deal with mid-line changes to/from blank line mode. Even if it turns out that they generate pixels. 2016-01-29 21:14:13 -05:00
Thomas Harte
f727582911 Started making first moves towards stripping CSCathodeRayView of its responsibilities. If that can be merely an OpenGL view that presents things, things will be a lot more portable. 2016-01-20 08:21:33 -05:00
Thomas Harte
956b90e203 Attempted further to improve latency; added view adjustment for non-4:3 output aspect ratios. The 4:3 is currently hardcoded, so further work will be required. 2016-01-18 23:55:52 -05:00
Thomas Harte
6112f4ef6b Withdrew soft filtering for now; until the sampling frequency is passed on it's not sufficiently rigorous. 2016-01-12 16:42:16 -05:00
Thomas Harte
75d6ec354b Added some very basic filtering in RGB mode. 2016-01-12 16:27:09 -05:00
Thomas Harte
3d6f20b7b9 Output, at last! Though sync is clearly way off. 2016-01-09 21:53:33 -05:00
Thomas Harte
09df218c01 Some output! Showing that three lines of solid sync isn't smart. But here it is. 2016-01-09 21:48:53 -05:00
Thomas Harte
b4f31edea3 Made an attempt to get RGB output mode up and running, and showing at least a box where pixels would be. 2016-01-09 21:32:56 -05:00
Thomas Harte
0db8938d27 Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least. 2016-01-06 23:14:36 -05:00
Thomas Harte
616dc0b57c Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping. 2016-01-04 23:40:43 -05:00
