a38639d099 Eliminates the concept of an iCoordinate.
Real-life precision appears not to support the idea of sub-sample pixel storage.

6547560e52 Gives the CRT the ability to move iCoordinate multiplication outside of the fragment loop.
That resolves precision issues, as were plaguing the Apple II.

23c34a8c14 Corrects calculation of intermediate buffer width multiplier.
Specifically: I had failed to factor in that the multiplied-up input frequency might be less than than the full width of the bitmap.

The Atari and MSX in particular now look much better.

93ece2aec7 "Doubles" the bandwidth given to composite signals.
Because I suspect it may inadvertently have been halved previously. I'm investigating.

bded406caa Initialize all const members.
Without this change, GCC versions >4.8 will error with things like:

```
./CLK/Outputs/CRT/Internals/CRTOpenGL.cpp:154:2:error: uninitialized const member
'Outputs::CRT::OpenGLOutputBuilder::draw_frame(unsigned int, unsigned int, bool)::RenderStage::target'

2e15fab651 Doubles down on <cX> over <X.h> for C includes, and usage of the namespace for those types and functions. 2017-11-11 15:28:40 -05:00

c0055a5a5f Further builds up SConstruct, correcting many missed imports and a couple of improper uses of C99 in C++ code. 2017-11-09 22:04:49 -05:00

6cb95b4fc5 Switched to passing around std::strings rather than char *s, because they should be easier to capture. 2017-02-20 10:35:33 -05:00

c2d7e36c8f Ensured logic for whether composite output is in use is consistent. 2017-01-25 21:25:03 -05:00

5761c8267b [Re-]Eliminated connection between colour subcarrier frequency and monitor output mode. 2017-01-24 20:48:54 -05:00
Thomas Harte
b4159295f6 Switched to using quads for intermediate draws. The specific concern is the flexibility offered in the GL spec as to line drawing algorithms. And even if a driver implements exactly to spec then it should omit the final pixel. 2017-01-11 21:18:41 -05:00

4c3669f210 Reduced precision of input phase, but I'm not necessarily persuaded by it as a move. However it's clear that something is off in that whole area. But if phase is locked by output position, do I need to retain this level of complexity? Also ensured that intermediate buffers prior to the final are sampled using the nearest sampling mode, also to reduce precision errors. 2017-01-10 22:08:07 -05:00
Thomas Harte
3d789732a2 Switched back to full buffer clearing. Until I can figure out the source of noise. 2017-01-08 19:50:31 -05:00

7ad64ff16b Made further efforts to support throughput via memory barrier. 2017-01-08 14:47:16 -05:00

be48c950b4 Started taking steps towards using a texture barrier where possible to reduce all of my framebuffer binds. Some output appears, but it's not correct. 2017-01-08 11:13:20 -05:00

0487b8c178 Definitively eliminated the additional y filtering step; if I'm going to work to ensure always four samples per colour cycle, I can put the channel separation coefficients directly into their shaders, cutting down on samples. 2017-01-07 16:02:33 -05:00
Thomas Harte
5740015f56 Temporarily disabled composite processing to show the pure stream. Fixed both automatic calculations of phase — per line and, at input, per pixel. 2017-01-07 12:38:00 -05:00
Thomas Harte
c746a3711f Temporarily disabled my attempt to be clever with bilinear filtering when applying a lowpass filter. Will need to investigate. 2017-01-04 08:06:18 -05:00
Thomas Harte
aa7774a9a6 Experimental: up the chroma accuracy, just let the luma go straight through. Subject to figuring out how I'm still losing so much precision. 2017-01-03 22:41:34 -05:00
Thomas Harte
a836120945 Restored proper colour separation, but somewhere a massive hit in horizontal resolution is happening — much greater than one would expect from the sample size picked. So investigation to come. 2017-01-03 22:32:07 -05:00
