Thomas Harte	2bd71e7e9b	.reset is the more normal way to reassign a unique_ptr.	2016-06-23 20:52:44 -04:00
Thomas Harte	4ad074fc78	Introduced a four-cycle delay between playfield fetch and display, curing Yar's Revenge. Also disabled barrel roll scanling colouring again. I really need to make my mind up on that.	2016-05-16 19:55:56 -04:00
Thomas Harte	9d92ad659f	Established the basic timing loop, albeit without clocking delays yet.	2016-05-16 08:01:29 -04:00
Thomas Harte	00a2b42080	Made thread-safe.	2016-05-15 15:19:52 -04:00
Thomas Harte	091516e3cb	The semantics might need better exposition but: fixed UniformXfv calls plus matrix calls, documented new semantics on all setters.	2016-05-15 14:59:59 -04:00
Thomas Harte	328fabcd10	Ensured values aren't dangling pointers.	2016-05-14 18:15:10 -04:00
Thomas Harte	492dc7ccbf	Made an attempt to queue uniform changes until the next call to bind. That's to allow usage from other threads.	2016-05-14 18:06:55 -04:00
Thomas Harte	30f335fa35	Switched pervasively to using the named slot uniform setters on Shader.	2016-05-13 22:08:32 -04:00
Thomas Harte	b6d2c8cb63	Switched to instaced drawing for source[/intermediate] runs too, reducing that data transfer footprint by 50%.	2016-05-10 19:50:12 -04:00
Thomas Harte	47ae402f7e	Introduced a shorthand for setting up array attributes.	2016-05-10 19:11:48 -04:00
Thomas Harte	1d0bcb416d	Dropped the size per output run back down to 8 bytes.	2016-05-10 07:47:47 -04:00
Thomas Harte	b0f0315f12	Fixed: this now implements 12-byte instancing for output runs.	2016-05-10 07:30:12 -04:00
Thomas Harte	86dab3a5d6	Quickest first attempt to switch to instancing for the output array. Texture coordinates seem to be off.	2016-05-10 07:23:47 -04:00
Thomas Harte	7b5982e455	Removed last mentions of 'lateral'.	2016-05-08 20:51:28 -04:00
Thomas Harte	9b2061be98	Actually, that should probably be 1/outputTextureSize, as the output range is -1 to +1.	2016-05-08 16:09:39 -04:00
Thomas Harte	9485ef2c8c	At last a genuine bug fixed: was nudging the wrong amount in intermediate shaders.	2016-05-08 16:07:36 -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	c73751b15a	Reverted deliberately broken segments to produce something mergeable.	2016-05-05 21:27:13 -04:00
Thomas Harte	a74f081aa9	Put lateral lookup table directly into the shader.	2016-05-05 21:21:27 -04:00
Thomas Harte	f621cc8523	Withdrew the pixel unpack buffer in order to avoid the potential for a paused machine to be undrawable. The cost is at least an extra memcpy per frame; I'm letting the driver worry about the whole process for now.	2016-05-04 21:27:10 -04:00
Thomas Harte	535d272039	Tweaks here, tweaks there.	2016-05-03 18:15:24 -04:00
Thomas Harte	6d5a1b33ee	Turned the colour up just a little, slightly lowered luminance signal strength.	2016-05-03 07:51:14 -04:00
Thomas Harte	31f1e6d5c0	Introduced a separate stage for luminance filtering.	2016-05-03 07:46:40 -04:00
Thomas Harte	29e7c96e4c	Brought monitor mode inside the pipeline and added an intermediate filter.	2016-05-02 21:05:58 -04:00
Thomas Harte	c93bcf9f28	Discovered cause of clears: stale code. Tweaked persistence, again.	2016-05-01 22:28:33 -04:00
Thomas Harte	6982e945fb	Fixed those issues breaking GL state, I hope.	2016-05-01 16:17:52 -04:00
Thomas Harte	2616d748fe	Introduced bind-if-necessary/unbind semantics for shaders.	2016-05-01 11:07:49 -04:00
Thomas Harte	fe2abbd4ed	Minor adjustments to ensure sampling occurs as intended.	2016-04-30 20:48:09 -04:00
Thomas Harte	16ef09fc2b	Made an attempt intelligently to use bilinear filtering to increase filtering quality with the same number of samples.	2016-04-29 18:37:35 -04:00
Thomas Harte	23ea832f41	Increased brightness in television mode, added a clear if screen resolution changes.	2016-04-28 22:04:47 -04:00
Thomas Harte	3638414b37	Added additional comments.	2016-04-28 21:55:14 -04:00
Thomas Harte	e6c3b148ac	Switched wholeheartedly to the new shader.	2016-04-28 21:45:44 -04:00
Thomas Harte	8538b62ea2	Made an attempt to extract and consolidate the logic behind the intermediate shaders.	2016-04-28 21:04:59 -04:00
Thomas Harte	87c778ebb7	Fixed code use of parameter name.	2016-04-27 22:58:53 -04:00
Thomas Harte	494ef6a324	Updated documentation, taking the opportunity to improve a parameter name.	2016-04-27 22:57:40 -04:00
Thomas Harte	8849dc3265	Finished consolidation into OutputShader. With its documentation yet to update.	2016-04-27 22:41:32 -04:00
Thomas Harte	496d979aca	Made a decision to clean up by creating per-shader classes. Well, more or less. First thing to be factored out: the output shader.	2016-04-27 22:29:54 -04:00
