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.

CapitaineSheridan 1b066fe4b3 Crosshair refactor
-add a new separate class for crosshair
-crosshair coordinates are calculated by matrix instead of recreating every object at correct coordinates
-add ability to scale crosshair by dpi
-add ability to use bitmap crosshair (located in ./Media/). 32bits bmp format + alpha
-cmd line "-bitmapcrosshair" or "-vectorcrosshair" and/or BitmapCrosshair=0|1 in config file
-these changes are only for lost world game with Crosshairs=1|2|3

don't forget to copy the 2 crosshair images in Supermodel/Media folder

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 :]

Ian Curtis 8aa476aeeb Previous mpeg audio code worked for me in debug mode, but the release build had some serious corruption issues when being built in visual studio. Replaced the old spaghetti code with a more modern implementation. 2019-02-21 14:56:25 +00:00
Ian Curtis b5f9ad9651 Quad rendering engine. Set QuadRendering = 1 in the ini file to use, or -quad-rendering at the end of the command line to use. 2018-09-13 12:50:34 +00:00
Ian Curtis c7ffd0a808 Draw transparent polys to separate layers and composite at the end. This solves a tonne of transparency errors we had been battling with for a long time. The model3 is strange in the fact it only supports a max of two translucent overlapped polys. They are not blended into the frame normally. Doing this means the topmost translucent polys only are visible in the scene, the equivalent of doing a depth pass first, but without the added cost. 2018-06-16 21:31:29 +00:00
Ian Curtis 04758e38b6 Update make files and fix build for the various options (Harry Tuttle) 2018-01-22 21:01:35 +00:00
Ian Curtis 6efa03112e Rewrite projection maths based upon previously unknown viewport values. The previous values used roughly worked as the normals for frustum planes. Perhaps they were only used for culling and not actually rendering, as sometimes the values don't work correctly. 2018-01-08 18:35:42 +00:00

Ian Curtis edfb521a9b Daytona seems to use this completely undocumented feature of the real3d pro-1000, the ability to invert texture colours. This patch fixes the colours on the cars, and the signs which should flash by alternating their colours. 2017-04-05 17:57:38 +00:00

Ian Curtis c2b1db11f8 Cull geometry based on the culling distances in the nodes. Should give some sort of speedup on lower end pcs where the CPU is predominantly the bottle neck. 2016-06-16 20:05:29 +00:00
