Ian Curtis 8dda8e9105 Fix the line of sight function.
Polygons have a line of sight value that's either a 0 or 1. We write this value into the stencil buffer, then read the app can read it back to determine the polygon attribute is visible or not. The returned value is 1/depth value in world coordinates. The first bit of the float is actually a control bit, 1 indicates no geometry hit, 0 indicates geometry hit.

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

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
