Thomas Harte	a82fa31370	Switched back to broad locking for CRT updates. To eliminate one more thing.	2016-05-09 06:58:26 -04:00
Thomas Harte	47302de23a	Switched to simpler storage for _image.	2016-05-08 21:11:56 -04:00
Thomas Harte	1f02c5df88	Tidied up some further loose ends.	2016-05-08 20:58:18 -04:00
Thomas Harte	7b5982e455	Removed last mentions of 'lateral'.	2016-05-08 20:51:28 -04:00
Thomas Harte	986019f9f9	Fixed error that could lead to split output run vertex writes.	2016-05-08 20:30:59 -04:00
Thomas Harte	1a214a8308	Fence sync tied up. Remaining glitches are likely off-by-one-type errors but we'll see.	2016-05-08 19:45:36 -04:00
Thomas Harte	ef3b91d3aa	Made an attempt to get formal on synchronisation.	2016-05-08 19:42:33 -04:00
Thomas Harte	dd469fe83a	Switched back to normal frame drawing logic and cleaned up the circular range stuff a little, to make it clear that no errors lie there.	2016-05-08 18:50:30 -04:00
Thomas Harte	ccdbec3ffc	Corrected for potential lost lines.	2016-05-08 16:43:11 -04:00
Thomas Harte	a75259ce9f	Removed some dead caveman debugging statements.	2016-05-08 16:18:42 -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	8284b272ad	Picked appropriate new-world values for various buffers.	2016-05-05 20:00:28 -04:00
Thomas Harte	284b310074	Attempted to implement end-of-buffer tests for all stages.	2016-05-05 19:52:05 -04:00
Thomas Harte	e9a9cfb09f	Fixed off-by-one error on texture upload.	2016-05-05 07:22:49 -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	2e7ac0e6db	With a lot of logging also currently ongoing, fixed circular ranges for clearing and when covering an entire buffer.	2016-05-04 21:08:38 -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	3684c6404f	Proven through deliberate inefficiency: the issues are (i) texture upload; and (ii) buffer wraparound.	2016-05-03 22:22:12 -04:00
Thomas Harte	759fbd89ca	Switched pixel unpack buffer back to explicit flushes.	2016-05-03 21:26:09 -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	fc1a67c157	Lateral is no longer written per vertex. It's a fixed list.	2016-05-03 18:45:55 -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	4a0e1dc789	Switched to explicit flushing of data.	2016-05-01 22:33:00 -04:00
Thomas Harte	c93bcf9f28	Discovered cause of clears: stale code. Tweaked persistence, again.	2016-05-01 22:28:33 -04:00
Thomas Harte	09ed8eb654	Quelle surprise, failure to find strikes again. Fixed.	2016-05-01 21:07:27 -04:00
Thomas Harte	1b6754c5f8	Shuffled code, realised I wasn't actually binding my shader.	2016-05-01 19:22:24 -04:00
Thomas Harte	69984b54e5	Fixed aspect ratio storage. Adjusted indentation slightly.	2016-05-01 16:49:44 -04:00
Thomas Harte	6982e945fb	Fixed those issues breaking GL state, I hope.	2016-05-01 16:17:52 -04:00
Thomas Harte	4ec4cceb84	Made a first attempt at adding draw-as-a-quad functionality to texture targets.	2016-05-01 13:52:35 -04:00

Thomas Harte	501ab74eaf	Fixed time multiplier calculation.	2016-04-28 22:12:59 -04:00

Thomas Harte	3638414b37	Added additional comments.	2016-04-28 21:55:14 -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	ef3647f6cf	Being bold: per-scan timing isn't coming back, I think, so started completely removing it.	2016-04-27 23:00:43 -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	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
