3d003070b3 Made an attempt better to generalise the idea of things with 4 CLK delays. 2016-05-16 21:54:27 -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
f19ed2e8f8 Started merely attempting to reintroduce the background layer. 2016-05-16 19:04:13 -04:00
Thomas Harte
9d92ad659f Established the basic timing loop, albeit without clocking delays yet. 2016-05-16 08:01:29 -04:00

bf2932cd57 Merge pull request #16 from TomHarte/UniformSetters 
Implemented deferred setting of shader uniforms
 2016-05-15 15:22:06 -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
cca53598d3 Made another run at 2600 colours. 2016-05-14 16:52:24 -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
f487062c62 Merge pull request #15 from TomHarte/2600PAL 
Adds an implementation of the PAL-region colour phase shift formula
 2016-05-13 09:00:25 -04:00
Thomas Harte
8d52765f40 Realised why new shaders weren't taking. Very negligibly decreased Atari drawing cost. 2016-05-12 22:22:24 -04:00
Thomas Harte
6d65bc9b3a Permitted a wider error window on vertical sync, tidied things up a little and started trying to move towards full implementation of the OpenGL contract. 2016-05-11 22:11:01 -04:00
Thomas Harte
4b3c4082d2 These functions appear correctly to model the NTSC and PAL palettes; the CRT's attempt to switch function doesn't work properly yet though. 2016-05-11 21:07:18 -04:00

93760bf8fa Merge pull request #12 from TomHarte/FixedTests 
Ensured that calling `return_from_subroutine` really does unjam the processor if required
 2016-05-10 21:45:24 -04:00
Thomas Harte
e636ae37b4 Ensured that calling return_from_subroutine really does unjam the processor if required, causing all tests once again to pass. 2016-05-10 21:44:11 -04:00
Thomas Harte
5a4262d74e Confirmed: it is inaccurate for a 6502 to self reset at power up. So that responsibility now rests in the machines. 2016-05-10 21:05:52 -04:00

fab59cbc64 Merge pull request #11 from TomHarte/SourceInstancing 
Following the output run switch, switched also to instanced rendering for intermediate scans.
 2016-05-10 20:00:32 -04:00
Thomas Harte
a8ce021136 Fixed comment. 2016-05-10 19:59:03 -04:00
Thomas Harte
0d2d6a452d Fixed some dangling buffer management issues. 2016-05-10 19:55:34 -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
7369139f7e Realised that phase time can fit inside a single byte, since it's always (well) within the first quarter of the line — and if it somehow weren't (?) then taking it modulo the frequency would do. 2016-05-10 19:14:57 -04:00
Thomas Harte
47ae402f7e Introduced a shorthand for setting up array attributes. 2016-05-10 19:11:48 -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
309313c470 Update CRTConstants.hpp 
Lack of data duplication means this storage can be smaller.

fa34b9c67b Merge pull request #10 from TomHarte/NewInstancing 
Introduces use of array instancing for output runs.
 2016-05-10 07:51:27 -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
4592458ea0 Merge pull request #9 from TomHarte/RollingBlackLine 
Found and fixed off-by-one error.
 2016-05-09 21:16:58 -04:00
Thomas Harte
daec21d3d8 Found and fixed off-by-one error. Display should now be completely fixed. 2016-05-09 21:14:59 -04:00
Thomas Harte
e532786f40 Merge pull request #8 from TomHarte/ArrayRestarts 
Switches to always filling GL-headed arrays from 0
 2016-05-09 19:23:03 -04:00

59d766b325 Rationalised buffer sizes. 2016-05-09 19:17:03 -04:00
Thomas Harte
7e2bd78891 With an eye towards instancing, moved away from circular buffers. 2016-05-09 19:14:30 -04:00

e8a0a28018 Merge pull request #6 from TomHarte/GarbageLines 
Fixes the two most obvious potential causes of garbage lines
 2016-05-09 07:54:37 -04:00

ad734f341f Attempted fully to perfect memove, albeit that it's not affecting either current machine. 2016-05-09 07:44:05 -04:00

8eb058064c Fixed: ensured that the attempt to plot a misplaced write occurs correctly. 2016-05-09 07:42:26 -04:00
Thomas Harte
e6a7161e87 Made some minor corrections on the copyback of misplaced write data. 2016-05-09 07:39:57 -04:00
Thomas Harte
45af963b9a Moved more of the circular logic inside getCircularRanges in order to eliminate one more potential source of error. 2016-05-09 07:34:37 -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
cec9ad0dc6 Switched to a more rational interface, ensured output_level will work when eventually needed, and that neither it nor output_data attempts a recursive lock. 2016-05-09 07:02:12 -04:00
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
95ee2fffdb Merge pull request #5 from TomHarte/Glitches 
Started tackling the sources of graphical glitching
 2016-05-08 21:16:06 -04:00
