Ryan Holtz	f42b5ccda0	No whatsnew ... Attempting to fix the HLSL 'blurriness' reported by a few people. Now HLSL will auto-prescale to the nearest texture size that is greater than the target screen size on both axes and is also an even multiple of the raw bitmap's size.	2011-05-31 13:53:25 +00:00
Ryan Holtz	ed6689e2d4	Fixed scanlines, nwn. This took much longer to fix than it should have. :[	2011-05-31 05:02:17 +00:00
Ryan Holtz	37e8c1d7e4	Fixing some scanline-alignment issues.	2011-05-31 02:04:28 +00:00
Ryan Holtz	244eb4cf24	No whatnsew: Really, really, really fixed the remaining pixel alignment and UV clamping issues. Tested Gradius, Pac-Man, Mr. Do, and Stompin' with no observed issues. Gradius, in particular, is a good test case as the bottom row of its "Credits" readout lies on the bottom row of pixels, and the scrolling starfield allows visual verification of the X extents as they scroll on and off.	2011-05-28 14:14:05 +00:00
Ryan Holtz	3e437e09f0	HLSL updates, nwn: ... - Favor bilinear sampling on X and point sampling on Y. Best of both worlds.	2011-05-27 23:24:53 +00:00
Ryan Holtz	c8ef077d5b	HLSL Updates: [Ryan Holtz, Bat Country Entertainment] ... - Switched to point-sampling through most of the shader chain to avoid non-intentional pixel smearing - Corrected alignment and scaling on the shadow mask and scanlines; dramatically reduces rainbow banding at non-oversampled resolutions.	2011-05-27 10:07:11 +00:00
Ryan Holtz	e97aa6b56d	Internal HLSL cleanup - removed aux texcoords, restored software vertex processing due to low-end cards not doing hardware vertex processing, removed unnecessary tristrip->trilist splitting. Restores D3D functionality on integrated chipsets and marginal cards. [Ryan Holtz, Ashura-X]	2011-05-24 18:28:54 +00:00
Ryan Holtz	ae9fbbe44d	NTSC fixes, nw	2011-05-23 01:53:35 +00:00
Ryan Holtz	41d1d2acdc	TortoiseSVN indicates these didn't get updated, this should finally nail down the texture border pixel stretching issue, nwn	2011-05-22 03:48:13 +00:00
Ryan Holtz	a47bd09534	HLSL Improvements: [Ryan Holtz, Bat Country Entertainment] ... - Added magnet deconvergence via a shader uniform - Improved phosphorescence - Improved YIQ codec	2011-05-21 06:47:56 +00:00
Ryan Holtz	f3d341a544	Initial shader import (nw) ... Focus: 8-sample blur that averages 7 samples around a center sample. Phosphor: Not currently used, treated as a pass-through by drawd3d.c, but could be used to implement additional convolutions in a second pass. Pincushion: Used (when commented in in drawd3d.c) to pincushion an entire full-screen texture but not otherwise apply any convolutions. Post: The meat and potatoes. It does scanlines, it does aperture masking, it does dot crawl, it does chroma subsampling, it does YIQ colorspace convolution, it does RGB colorspace convolution, it does pincushioning, it walks, it talks, it does the dishes, it'll screw your wife for you, and if you don't have a wife it will find one for you, get you married to her, and screw her for you, IT IS THAT GOOD, LADIES AND GENTLEMEN. Primary: Simple passthrough for UI and artwork.	2011-05-16 16:55:34 +00:00
