1 | //NOTE: You can find the set of original Unai poly routines (disabled now) |
| 2 | // at the bottom end of this file. |
| 3 | |
| 4 | //senquack - Original Unai GPU poly routines have been replaced with new |
| 5 | // ones based on DrHell routines. The original routines suffered from |
| 6 | // shifted rows, causing many quads to have their first triangle drawn |
| 7 | // correctly, but the second triangle would randomly have pixels shifted |
| 8 | // either left or right or entire rows not drawn at all. Furthermore, |
| 9 | // some times entire triangles seemed to be either missing or only |
| 10 | // partially drawn (most clearly seen in sky/road textures in NFS3, |
| 11 | // clock tower in beginning of Castlevania SOTN). Pixel gaps were |
| 12 | // prevalent. |
| 13 | // |
| 14 | // Since DrHell GPU didn't seem to exhibit these artifacts at all, I adapted |
| 15 | // its routines to GPU Unai (Unai was probably already originally based on it). |
| 16 | // DrHell uses 22.10 fixed point instead of Unai's 16.16, so gpu_fixedpoint.h |
| 17 | // required modification as well as gpu_inner.h (where gpuPolySpanFn driver |
| 18 | // functions are). |
| 19 | // |
| 20 | // Originally, I tried to patch up original Unai routines and got as far |
| 21 | // as fixing the shifted rows, but still had other problem of triangles rendered |
| 22 | // wrong (black triangular gaps in NFS3 sky, clock tower in Castlevania SOTN). |
| 23 | // I eventually gave up. Even after rewriting/adapting the routines, |
| 24 | // however, I still had some random pixel droupouts, specifically in |
| 25 | // NFS3 sky texture. I discovered that gpu_inner.h gpuPolySpanFn function |
| 26 | // was taking optimizations to an extreme and packing u/v texture coords |
| 27 | // into one 32-bit word, reducing their accuracy. Only once they were |
| 28 | // handled in full-accuracy individual words was that problem fixed. |
| 29 | // |
| 30 | // NOTE: I also added support for doing divisions using the FPU, either |
| 31 | // with normal division or multiplication-by-reciprocal. |
| 32 | // To use float division, GPU_UNAI_USE_FLOATMATH should be defined. |
| 33 | // To use float mult-by-reciprocal, GPU_UNAI_USE_FLOAT_DIV_MULTINV |
| 34 | // can be specified (GPU_UNAI_USE_FLOATMATH must also be specified) |
| 35 | // To use inaccurate fixed-point mult-by-reciprocal, define |
| 36 | // GPU_UNAI_USE_INT_DIV_MULTINV. This is the default on older |
| 37 | // ARM devices like Wiz/Caanoo that have neither integer division |
| 38 | // in hardware or an FPU. It results in some pixel dropouts, |
| 39 | // texture glitches, but less than the original GPU UNAI code. |
| 40 | // |
| 41 | // If nothing is specified, integer division will be used. |
| 42 | // |
| 43 | // NOTE 2: Even with MIPS32R2 having FPU recip.s instruction, and it is |
| 44 | // used when this platform is detected, I found it not to give any |
| 45 | // noticeable speedup over normal float division (in fact seemed a tiny |
| 46 | // tiny bit slower). I also found float division to not provide any |
| 47 | // noticeable speedups versus integer division on MISP32R2 platform. |
| 48 | // Granted, the differences were all around .5 FPS or less. |
| 49 | // |
| 50 | // TODO: |
| 51 | // * See if anything can be done about remaining pixel gaps in Gran |
| 52 | // Turismo car models, track. |
| 53 | // * Find better way of passing parameters to gpuPolySpanFn functions than |
| 54 | // through original Unai method of using global variables u4,v4,du4 etc. |
| 55 | // * Come up with some newer way of drawing rows of pixels than by calling |
| 56 | // gpuPolySpanFn through function pointer. For every row, at least on |
| 57 | // MIPS platforms, many registers are having to be pushed/popped from stack |
| 58 | // on each call, which is strange since MIPS has so many registers. |
| 59 | // * MIPS MXU/ASM optimized gpuPolySpanFn ? |
