Replace network code with new tcp implementation

If we passed floats we could skip the shader logic.Ĭache variable, without it is unusably slow in debug modeĪdd SDLnetworking + some basic tcp classes Colours are passed to the GPU as unsigned bytes to multiplying by 16 will overflow, so we do the logic in the shader. The translator map seems to work with paletted colour values too, and the result is not clamped. Anyway virtua on is overflowing these values for some of the smoke effects. When the translator map is enabled the colour values seem to use 4 bits, 0-16. Tweak value so the map indicator still works at the start of spikeout Stretching the near plane a few % is enough to fix it. Scud is rendering non planar quads and this breaks our algorithm a little when using the quad renderer. Sutherland-Hodgeman clipping only works for planar primitives. Only need to clip against 4 planes for poly culling Doing the maths with double precision and casting back to float was enough to fix the issue. Basically we were running out of precision in a rare corner case. Anyway this fixes quad rendering looking broken with the latest nvidia drivers.įix the sky in harley in first person mode where pixels in the sky are culled when they shouldn't be with the quad renderer. Our algorithm was culling these out so the mipamp calculation failed for edge pixels. If there are no adjacent pixels the hw may need to spawn invisible fragments outside of the visible polygon. To calculate the mipmap value the opengl needs to calculate the difference in the texture coordinates between adjacent pixels. Really should cull against 5 frustum planes. Otherwise they end up getting written at like 99.8% of the frame and overlapping with the next. Stretch the time the ping_pong bit flips a bit to bump writes into correct frame. We aren't 100% sure if IRQ2 or the ping_pong bit is vblank. When the ping_pong bit flips at 66% of the frame time, games were writing data for a new frame, which meant writes were often straddling 2 separate frames. This mostly worked, but some games were writing more or less frames than they should have been for a given time period. Unfortunately we didn't have the correct values and just manually used some per game hacks to get games to run. The h/w polls something called the ping_pong bit at start-up to sync the GPU with the CPU. Thanks to our anonymous contributor who managed to patch a model 3 game and run it on real h/w, we were able to obtain some timing values we had been long been missing for correct emulation. The hardware must have some method to sanitize the near/far for instance if you render something extremely close to the origin you will also blow apart any near/far calc. Ocean hunter in the middle of the game is passing a few matrices with FLT_MAX inside them, which blows apart our near/far calculation. Replaced the old spaghetti code with a more modern implementation.įix possible negative pointer arithmetic which was causing the music to wrap around.Ī culling node must follow immediately after a viewport. Previous mpeg audio code worked for me in debug mode, but the release build had some serious corruption issues when being built in visual studio.
