Ian Curtis cdf5e4b2b2 Fix transparency depth testing ... The two transparency layers, might not be separate layers at all. We believe the hardware is writing each layer to every other pixel (stipple alpha), then using an anti-aliasing filter to effectively blend the pixels. Because the pixels don't overlap they don't depth test against each other. We are using separate layers to emulate this, so the depth buffer must be saved and restored between the layers.		2023-11-17 16:07:20 +00:00

Legacy3D	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.	2023-10-14 20:05:00 +01:00

FBO.cpp	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.	2023-09-23 15:27:04 +01:00

IRender3D.h	Smooth texture repeat makes no sense for alpha/contour textures with pixel dilate. HW seems to treat them as non smooth anyway. Also implement some line of sight stuff, used by Scud. Really need to check the threading/synchronisation of the register reads but it basically works.	2018-10-19 20:59:46 +00:00

Shader.cpp	fix some real errors (Model3,InputSystem), minor errors (SCSP,SDL/Main) and some performance warnings	2022-07-11 17:43:59 +02:00
Shader.h	missed 2 changed files with last commit	2022-07-11 18:27:44 +02:00
Shaders2D.h	gm_mathew - the line scroll values, the top 16bits are the even lines, the bottom 16bits are the odd lines. We had it swapped. This fixes the number below the word results in daytona, when you finish a game.	2023-10-31 23:50:19 +00:00
