Ian Curtis 538a714086 Fade out microtextures with higher textures LODs. Fixes incorrectly applied microtextures in LA machineguns. 2018-10-23 00:16:23 +00:00
Ian Curtis bf4d725970 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
Ian Curtis 42eaa7f3d8 fix copy paste error :] 2018-10-14 10:05:24 +00:00
Ian Curtis 3eeec35e7c Correctly emulate the real3d pro-1000 texture modes in our shader. 2018-10-13 13:29:45 +00:00
Ian Curtis 7bcc70a170 Update makefile 2018-10-01 17:42:45 +00:00
Ian Curtis 3dbfa73734 Both lemans24 and dirt devils are rendering some totally transparent objects as the first model in each viewport. The HW seems to skip these entirely, and including them breaks our near/far plane calculations leading to Z fighting. 2018-09-19 20:43:41 +00:00
Ian Curtis e3255e45f3 Tweak the ratio for the near plane. Fixes missing text on the map indicator at the start of spikeout. The vertices are 0.003 units apart so a tonne of precision is required at the near plane to not depth test out. 2018-09-18 21:46:38 +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 e4f5f0bcaf Sega bass fishing is starting some off the meshes with a shared vertex. Without having a previous vertex to share with, the values were just uninitialised and junk. The hardware itself seems to hold the value from the previous mesh, and sega bass fishing relies on this undefined behaviour to function correctly. Storing the cached vertices as member variables instead of locally to the function means it holds the values from the last mesh, and uses those values instead of random garbage. 2018-09-02 21:36:24 +00:00

Ian Curtis 73ff32a10d fix cast, and remove extra ; that had snuck into the shaders 2018-06-18 10:24:46 +00:00
Ian Curtis f9be1259c0 Opaque polys definitely depth test with less than or equal. Virtua striker is drawing co-planar polys for the bar gfx 2018-06-17 11:30:01 +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 4d275ba49e Parse siblings after children. It's the only way to get Daytona water fall to look correct without h/w poly sorting. 2018-05-03 18:37:49 +00:00
Bart Trzynadlowski 3f9b1b76e5 Added a stretch mode (-stretch) and modified new renderer's viewport code (hopefully correctly) to handle aspect ratio correction and widening the way the legacy one does. 2018-05-03 03:46:44 +00:00
Ian Curtis c6b86c0812 Render the opaque part of texture transparency in the first pass. Fixes numerous transparency related issues in lemans24 and some in ocean hunter. I don't really know if this is the 'correct' way of solving this because the real3d pro-1000 is a complete black box. There is still a lot we don't understand about how it handles transparency. 2018-05-02 20:10:02 +00:00

Ian Curtis b184ca3e1b Clamping must be applied before the spotlight is applied on step 1.0 h/w. 2018-03-10 09:13:28 +00:00

Ian Curtis d708ce9ba2 top/bottom were swapped for off axis projection 2018-01-10 16:08:02 +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 cc28d5f00e Implement sub 8x8 tile encoding. Fixes incomplete mipmap chains which previously only went down to 8x8 pixels before. It wasn't known these textures existed before. (Harry Tuttle) 2017-12-17 22:25:50 +00:00
Ian Curtis cede67468c Fix some bad/missing textures in fighting vipers. The game is referencing totally illegal texture sizes. The real h/w was just handling it somehow, whilst we were returning null for the textures. This might produce junk textures for the lower mipmaps, but this can be clamped in a later update. 2017-12-13 01:21:25 +00:00
Ian Curtis 62d9584b0d Shift fog maths to fragment shader to fix bug in virtua on. 2017-11-23 17:51:51 +00:00
Ian Curtis bddc86aba9 The vertex shader is run before clipping is done. If fogging values are calculated and clamped in the vertex shader it can interpolate bad values, since the range has been truncated. This happens if the polys overlap the near plane. The solution to clamp the values in the fragment shader. This fixes a bunch of fogging errors I long thought were transparency related errors in the ocean hunter. 2017-11-20 22:21:15 +00:00
Ian Curtis bc7f1e9fac Fixed shading also works with untextured polys. Fixes some shading issues in La machineguns. (Harry Tuttle) 2017-11-07 00:15:57 +00:00
Ian Curtis df44ad458b Update step 1.5 luminous logic with Harry's findings. Fixes various shading issues. 2017-11-05 13:25:33 +00:00

Ian Curtis 7f6df0cc84 Remove fixed shading check from specular. 2017-10-07 12:39:30 +00:00
Ian Curtis eb798ed15e Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle) 2017-10-05 19:15:00 +00:00
Ian Curtis 43cf6b3bbf update spotlight code (Harry Tuttle) 2017-10-05 18:49:08 +00:00
Ian Curtis 9bac7836ed add missing header 2017-09-30 19:05:04 +00:00
Ian Curtis 0afd9026dc Fix the sky in one of the levels in virtua on. The problem was caused by the fact we didn't split the mesh by the fog % burn through, so all the polys had the same value. We could use a vertex attrib, but % burn through fog is so rarely used and when it is, normally every poly in the mesh has the same value. 2017-09-26 00:30:08 +00:00
Bart Trzynadlowski 55bb02d4e5 - New work-in-progress frame timing code (disabled by default, compile with NEW_FRAME_TIMING defined to activate it)
- New JTAG emulation, moved into its own class, CJTAG
- Removed game-specific sun clamp hacks from CNew3D (JTAG and Real3D emulation will call the appropriate method to configure this at run-time)
- Removed JTAG from Real3D save state data and reused some of that space for new state variables having to do with the internal JTAG-based config as well as new frame timing state variables

Ian Curtis a3e2fb7906 Calculating the length of the vertex results in quite broken values for fogging when the vertices are traversing the view frustum. The hardware also wouldn't have been doing a square root per vertex for fogging. Simply using the z values is enough. Todo check clamping of values for the near/far planes. 2017-09-06 13:07:39 +00:00
Ian Curtis 2786d95795 add interface for sun clamp 2017-09-02 14:54:16 +00:00
