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 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 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 165926aa06 Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions. 2017-08-29 10:27:29 +00:00
Bart Trzynadlowski f04a285727 DMA and register space access for Real3D have been unified and CReal3D::ReadRegister() returns little endian data now that the PowerPC handler byte-swaps back, to be consistent with how DMA registers work. 2017-08-29 01:28:21 +00:00

Ian Curtis cd5978773a Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade. 2017-08-19 20:06:31 +00:00

Ian Curtis 0efd4dac39 Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading. 2017-08-15 23:21:57 +00:00
Ian Curtis b1cc9a615d With fixed shading, when lighting is disabled, fixed shading appears to be a flat shaded version based upon the poly colour, instead of per vertex attributes. 2017-08-15 20:50:36 +00:00

Ian Curtis 5709ee2659 Sometime ago I managed to work out that specular on the model3 is not real specular, and really is just an extension of diffuse lighting. But attempts were derailed by corner cases and the fact we were not handling the normals correctly. Anyway Harry managed to successfully come up with an algorithm, and coefficients that give an almost perfect match to specular on the model3, based soley on observations from video footage! He also worked out that the lighting on hardware 1.5 onwards appears to be unclamped (ie greater than 1). This quite radically changes the brightness of some of the games, but much better matches the original hardware. 2017-08-09 16:56:56 +00:00

Ian Curtis 3fc28159eb Add the unclamped light model we know exists to the shaders. 2017-08-03 10:41:18 +00:00
Ian Curtis b1bd877b82 Ski champ for some reason is passing denormalised numbers for the modelscale. This is causing a NaN in our shader killing the lighting for these models, so we simply skip these, since they are essentially zero anyway. Thanks to Harry for finding this bug :) 2017-08-01 23:48:53 +00:00
Ian Curtis 9aa3f13777 We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model. 2017-07-29 16:30:30 +00:00

Ian Curtis 3efb055344 Clamp the ambient light to a max of 0.75. LA Machine guns seems to use an ambient value of 1, which is full bright for everything. But for some reason the hardware seems to treat this as ~ 0.75. This fixes various missing shading in the game. This doesn't seem to have any negative effects on other games I have tested. Clamping in the shader as we might need the full range of values for fixed shading. 2017-06-29 19:05:30 +00:00

Ian Curtis 97781108e8 A second go at fixing the fixed lighting in star wars .. Fixed shading is per vertex poly colours. For some reason in star wars they are treated as unsigned values instead of signed, like in every other game. These polys are all marked with specular enabled, where as in the rest of the games they are missing this flag. That's the only difference I can find. 2017-06-21 17:04:53 +00:00

Ian Curtis 3c78571615 There are 2 bits in the polyheader labelled discard. When both are set ie in sega rally, the polygons are totally discarded. Scud seems to set bit 1 which seems halve the opacity. 2017-04-15 19:00:46 +00:00
Ian Curtis 21836c088c The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded. 2017-04-14 23:41:11 +00:00

Ian Curtis 391aafd4c1 Virtua fighter has a few massive polys that shouldn't be visible. It looks like these polys have a bad matrix, but the node distances are all zero.

Ian Curtis ff624afb4d The mipmap data in some games seems to being sent behind the base textures, and when the base textures are bound and created the mipmap chain is not yet valid in memory. To fix this, we invalidate the base textures, when the mipmap chain is updated. 2017-03-25 00:06:24 +00:00
Ian Curtis 06c1cdcf94 Just use 1 hash map for the textures, instead of 1 for each format. Should greatly speed up texture invalidation. TODO invalidate texture mipmaps .. the h/w actually seems to stream the mipmap data separate from the base textures in some cases. 2017-03-24 20:54:12 +00:00

Ian Curtis 82ac030dff calculate the correct number of mipmap textures 2017-03-24 16:51:52 +00:00
Ian Curtis 17f878421b Originally to do mipmapping, I just used the base texture and then let the h/w automatically generate the mipmap chain. I wasn't sure the real3d api even exposed to the programmer the ability to directly set the mipmap data. Anyway, as pointed out by HarryTuttle scud actually uses darker mipmaps for an effect on the water. This patch uses the uses the actual mipmap data from the real3d memory. Only tested scud, so hopefully I didn't cause any cataclysmic errors :) 2017-03-24 13:38:20 +00:00

Ian Curtis 9780f333b4 The model3 has this weird issue where the 2d and 3d planes are misaligned by 2 pixels. Originally I made a quick hack that shifted subviewports 2 pixels. But apparently that wasn't enough, as the issue effects everything. Thanks to HarryTuttle for pointing this out, and making a patch :) 2017-03-19 01:33:45 +00:00
Ian Curtis b19ceb0b6a Texture coordinates seem to be scaled relative to the fixed texture size of 256. Thanks to HarryTurtle for figuring this crazy logic out. The road in scud matches the arcade now almost perfectly. 2017-03-13 00:59:35 +00:00
Ian Curtis dcd018ab7e Change microtexture scaling values. Seem to much better match expected output. (thanks HarryTuttle) 2017-03-12 19:00:00 +00:00
Ian Curtis 732e3ef51f More fixes to microtexture coordinates. They go vertically up and down the texture sheet, and not horizontally as I had guessed. (Thanks HarryTurtle) 2017-03-11 12:55:47 +00:00

Ian Curtis f173c3c3ce The hardware actually seems to treat the quad primitive as a triangle strip. The winding order can actually change between the first and second 'triangle' inside the quad, leading our code to incorrectly backface cull the 2nd triangle. So we must re-calculate the winding order for the 2nd triangle. This fixes a massive missing poly in the road in la machine guns, probably other games too. The hardware is unaffected by the winding order, as it doesn't calculate the poly normal from the vertices directly, instead it uses the provided normal in the poly header. 2017-02-21 23:35:40 +00:00
Ian Curtis 5b9741bd5d Support high priority polygons. They are treated as a separate overlay plane by the h/w. Fixes some missing fx in harley. 2017-02-20 17:22:32 +00:00

Ian Curtis 4a116190b5 When the translator map?? bit is enabled the colour format seems to be 4-5bit. Max observed value is 16. Scaling these values up seems to produce the correct colours in harley and dirt devils. 2017-02-16 17:20:42 +00:00
Ian Curtis 7407d03036 Put a check in there, in case near values come out really close to zero. Fixes a slight corner case in lemans24. A check probably should have been there originally :) 2017-02-08 16:14:50 +00:00
Ian Curtis 24cbeed526 Dynamically calculate near/far frustum planes for each viewport priority layer by clipping the overlapping meshes with the 4 frustum planes. A bit brute forcy, but the results are great. 2017-02-07 14:05:03 +00:00

Ian Curtis 2c23268d88 Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess. 2016-12-09 14:13:46 +00:00
Ian Curtis da8b63b44b The model3 shares vertices between polygons. But it also seems to do this for polygons with different textures. This means the texture coordinate for potentially different sizes textures is shared. Currently this was broken leading to some corrupted looking textures. The fix is to simply cache the old texture coordinates, and recalculate the normalised coordinates in the new texture coordinate space. 2016-12-06 14:39:46 +00:00

Ian Curtis 665fa90425 Get clipping planes directly from the viewport data. Also no need to clip against a far plane 2016-11-26 01:12:08 +00:00
Ian Curtis 54c405709f Need to walk back in memory and check the previous texture tiles to see if they overlap with the current textures being invalidated. If they overlap they must be cleared too. Algorithm is a bit brute forcy and more expensive than I'd like but it fixes the bad textures in Spikeout. 2016-11-22 20:30:10 +00:00
Ian Curtis 84ae8f035c Skip processing the mipmap section of memory. The real3d doesn't create mipmaps down to 1x1 that is needed to do mipmapping properly on modern hardware anyway. 2016-11-21 09:04:56 +00:00
