Ian Curtis c5f9a3ad26 Amend the ambient fog logic to be disabled if fog density/start is set to zero. This fixes a regression where the sky stops drawing in lost world. 
Rewrite the scroll fog shader slightly. Scroll fog is a 2d layer, it has no depth, or can be considered to be drawn at infinity, therefore is not effected by the viewport light. The scroll attenatuion value also I think attenatutes the scroll fog alpha value. This fixes various effects in emergency call ambulance.

Ian Curtis a214c6dae8 Prior scroll fog logic was nearly correct. For scroll fogging to draw it needs either a start value or a fog density value, but these can come from a different viewport if they have the same colour fog set. This fixes the credits in vf3 which sets scroll fog, but it never draws on the original hardware. 
For a long time we've had bug reports that in vf3 the background in the Dural levels was the wrong colour, it should have been much darker. We thought it was again missing scroll fog, but gm_mathew worked out it was actually coming from the fogAmbient paramater. Not only does it darken the fog, but it also has an effect on the 2d background from the tilegen, similar to scroll fog. This also fixes the sky in lemans24.

Ian Curtis 79ddc8c739 Rewrite the logic for the scoll fog (render buffer clear colour). Each viewport can potentially have a scroll fog value so the logic of which value to pick wasn't immediately clear. TLDR I think it picks the highest value starting from the lowest priority layers. This fixes the sky in daytona battle on the edge. 2023-10-17 17:30:14 +01:00
Ian Curtis 86d477263f Scroll fog is like a clear colour for the render target, but can be semi transparent as the tilegen layer can be shown underneath. I assumed that transprent polys would be drawn to the render target for transparent polys but unfortunately the logic does not work. So where else could it be drawn? Well with limited memory it must be draw to the buffer for opaque polys, which means this render target is also blended. 2023-10-15 17:16:52 +01:00

Ian Curtis 6595b9320e Rewrite the renderer a bit to spit out the finished graphics from the 3d chip on separate buffers. One buffer is for opaque pixels, and 2 more for translucent pixels. Before the frame was composited on the back buffer, which meant the tilegen had to have been drawn first. This way the images are now totally independant of the tilegen chip so can be drawn as soon as the register write 0xC is written to the tilegen. 
Some games update the tilegen after the ping_ping bit has flipped at 66% of the frame, so we need to split the tilegen drawing up into two stages to get some effects to work. So having the tilegen draw independantly of the 3d chip can make this happen.

Ian Curtis d656643087 gm_mathew worked out that the camera flashes in sega rally 2 have the 'reset-matrix' attribute set inside the culling nodes, which was unsupported until now because we never found any games to have used this bit. The reset matrix is a bit strange, I would assume it would just reset the matrix back to identity, instead it seems to just reset the rotation back to identity whilst preserving the scale/position. 2023-09-27 16:33:53 +01:00

Ian Curtis c6ea81d996 Emulate the entire tilegen chip in a GLSL shader. (This is now possible with opengl 3+). The tilegen drawing was emulated on the CPU, but was one of the most expensive functions in the emulator according to a profiler. On a modern GPU it's pretty much free, because a GPU is a massive SIMD monster. 
Tilegen shaders are mapped to uniforms, and the vram and palette are mapped to two textures.

TODO rip out the redundant code in the tilegen class. We don't need to pre-calculate palettes anymore. etc

The tilegen code supports has a start/end line so we can emulate as many lines as we want in a chunk, which will come in later as some games update the tilegen immediately after the ping_pong bit has flipped ~ 66% of the frame.

The scud rolling start tilegen bug is probably actually a bug in the original h/w implementation, that ends up looking correct on original h/w but not for us. Need hardware testing to confirm what it's actually doing.

These 2 settings are usefull when setting up a multiplayer game on one machine.

Ian Curtis ad0aed42a4 be a bit more flexible with the display frequencies we'll match 2022-12-19 14:11:21 +00:00
Ian Curtis 25604512f4 The model 3 (actually model 1,2 and 3) all used some crazy refresh rate of 57.524hz. If your screen refresh rate is 60hz, supermodel will work fine, but really run too fast. Anyway if you create a custom refresh rate, supermodel will automatically pick this, and set it when the emulator is in fullscreen mode. Apparently this works with most monitors, even cheapo low end ones. 
To active set your command line to:
-res=1920,1080 -vsync -fullscreen -true-hz

Replace the resolution with whatever your monitor's native resolution is.

Ian Curtis 40c8259130 Rewrite the whole project for GL4+. I figured if we removed the limitation of a legacy rendering API we could improve things a bit. With GL4+ we can do unsigned integer math in the shaders. This allows us to upload a direct copy of the real3d texture sheet, and texture directly from this memory given the x/y pos and type. This massively simplifies the binding and invalidation code. Also the crazy corner cases will work because it essentially works the same way as the original hardware. 
The standard triangle render requires gl 4.1 core, so should work on mac. The quad renderer runs on 4.5 core. The legacy renderer should still work, and when enabled a regular opengl context will be created, which allows functions marked depreciated in the core profiles to still work. This will only work in windows/linux I think. Apple doesn't support this.

A GL 4.1 GPU is now the min required spec. Sorry if you have an OLDER gpu. GL 4.1 is over 12 years old now.

This is a big update so I apologise in advance if I accidently broke something :]

Thus making the result similar to the fp64 version, tested e.g. with harleys first person mode (all artifacts still gone as before).

Improves perf on low end boards (e.g. Intel) dramatically (10fps with harley before, now 70 on my laptop), and even on higher end (e.g. NVIDIA laptop, quads are now faster than tri pipeline on my laptop).

Bart Trzynadlowski 7be381c9ba Added configurable refresh rate. Default is 60 but -true-hz on the command line enables 57.524 Hz mode, which some players report making Spikeout and the timing of combos in VF3 more authentic. The config key is RefreshRate and is specified as a floating point value. Should the desire arise, arbitrary refresh rates can be set in Supermodel.ini using this key but almost no validation of the value is performed.
