Thomas Harte	0edc043378	Started introducing an extra layer of indirection so as to be able to bind the texture builder to the same flush and submit patern as the array builder.	2016-12-03 20:47:19 -05:00
Thomas Harte	cb3c837e30	Simplified interface by baking in last-minute-only updates.	2016-12-03 18:19:12 -05:00
Thomas Harte	0220d33562	Resolved failure of initial state setting, which was causing tests sometimes to fail.	2016-12-03 16:42:10 -05:00

Thomas Harte	7c85cb62e4	Moved underscores, removed indirections where they're not necessary, converted those names that were still looking very Objective-C and moved the GL fence variable into the private area, where it should always have been.	2016-11-21 12:14:52 +08:00
Thomas Harte	bc03e12dc5	Switched to suffix underscores.	2016-11-21 11:57:45 +08:00

Thomas Harte	d7d0ed378a	Only the final intermediate buffer needs clearing, on reflection.	2016-11-21 11:26:07 +08:00
Thomas Harte	c89345c639	Reduced buffer size.	2016-11-21 11:21:14 +08:00
Thomas Harte	32dbfe947d	With hindsight, the elimination of this might have been overzealous.	2016-11-20 10:53:35 +08:00
Thomas Harte	ef0367d4a4	Corrected typo.	2016-11-20 09:12:43 +08:00

Thomas Harte	c2349ee3f4	This thing has clearly becoma a real class.	2016-11-19 20:12:40 +08:00
Thomas Harte	7857ef774f	Ensured resets genuinely kill outstanding data.	2016-11-19 20:09:38 +08:00

Thomas Harte	aca1fa0577	Returned some video output. Enough significantly to reduce my paranoia.	2016-11-17 13:37:53 +08:00
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	57f0648742	Fleshed out first implementation of ArrayBuilder, albeit that I need to implement exhaustion properly, as soon as I think of a sensible way to handle synchronisation.	2016-11-17 10:39:30 +08:00
Thomas Harte	324a1de43d	Started pulling out array construction as a separate task.	2016-11-17 09:20:49 +08:00
Thomas Harte	c04a116a05	Fixed comment.	2016-11-16 23:14:56 +08:00
Thomas Harte	edeafd4d94	Wait, OpenGL textures go the other way.	2016-11-16 23:14:15 +08:00
Thomas Harte	6ac20e0066	Pushed responsibility for submitting texture contents up to the texture builder, simplifying the interface.	2016-11-16 23:13:06 +08:00
Thomas Harte	5c5e44874f	Even better: why include the 'Input' prefix when there's only one?	2016-11-16 22:57:17 +08:00
Thomas Harte	04b2688683	Attempted to reduce allocations.	2016-11-16 13:25:50 +08:00
Thomas Harte	c1a509910d	Documented this interface, albeit that the English could do with a second pass, and very sightly simplified inline with current usage.	2016-11-16 13:15:50 +08:00
Thomas Harte	4d0d5eb919	Renamed the 'input buffer builder' to the 'input texture builder' to be explicit about what sort of buffer, and killed the prefix since it's namespaced. Also switched to std::vector.	2016-11-16 12:31:32 +08:00
Thomas Harte	4ee4400801	Removed dead code.	2016-11-16 11:57:22 +08:00
Thomas Harte	6cb4950db4	Improved run-off area.	2016-11-16 11:53:15 +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
Thomas Harte	44d3fd6d5b	Fixed mistimed reset of the target output line. Now all that's left is occasional noise.	2016-11-16 11:22:12 +08:00
Thomas Harte	7a737e0790	Both pathways start with a buffer that clears to black. So no need to keep going on about it.	2016-11-16 11:12:08 +08:00
Thomas Harte	f63e849092	Sought completely to eliminate the outgoing concept of 'clearing zones'.	2016-11-16 11:10:34 +08:00
Thomas Harte	294adde344	Eliminated zoned clearing, in favour of a complete buffer clear on each load and attempted to reduce locking. But imperfectly.	2016-11-16 10:59:12 +08:00
Thomas Harte	ccedb6bea6	Introduced an intermediate buffer that collects lines before flushing them to the output buffer.	2016-11-16 10:49:18 +08:00
Thomas Harte	ba2adf8bb1	Normalised on std::vector rather than std::unique_ptr<uint8_t *> as (probably?) more idiomatic. Improved structure slightly. Introduced a container for line data, albeit one that isn't yet used.	2016-11-16 10:34:54 +08:00
Thomas Harte	9c550c594a	Moved audio work back into its own thread, but this time it queues up an all happens only upon a flush. Hopefully to resolve synchronisation cost concerns.	2016-11-09 21:17:50 -05:00
Thomas Harte	eccfdabeab	Temporarily disabled thread hop, until I can find a way to batch these things.	2016-11-03 22:52:02 -04:00
Thomas Harte	4258401384	Implemented flush, added a call to it from the filter speaker's destructor, to ensure no race conditions on accessing the various bits of instance state there and below.	2016-10-19 21:15:04 -04:00
Thomas Harte	c628b7c5c5	This is the real PAL frequency, I think.	2016-10-17 08:05:02 -04:00
Thomas Harte	1f857c619b	Fixed timing issues. Static box of frame achieved!	2016-10-12 21:42:36 -04:00
Thomas Harte	00e3ad9b04	Added a bit more ceiling for lowpass filtering on constrained machines.	2016-10-10 07:51:01 -04:00
Thomas Harte	e53455a936	Not having read the C++ synchronisation primitives before, this async task queue is probably incorrect. But nevertheless, let's have a quick go at employing it — in a hideously thread unsafe fashion — for audio generation. What can possibly go wrong?	2016-10-07 16:56:34 -04:00
Thomas Harte	dab3580111	Experimental: can I afford a lower sampling rate if there's a low-pass filter in effect?	2016-08-22 22:18:05 -04:00
Thomas Harte	1541273785	Moved responsibility for throwing in a low-pass filter up to the Vic, appropriately.	2016-08-21 18:13:31 -04:00
Thomas Harte	c783090980	It turns out that the Vic has a 1.6Khz low-pass filter. So added that.	2016-08-21 12:13:41 -04:00
