Common: Move Matrix classes out of MathUtil into their own files and make their interface more friendly. 2019-01-29 22:05:51 +00:00			`#include <numeric>`
Created a free look utility which only works on win32 right now. It lets the user fly around with the mouse and keyboard. Had to add some ugly matrix functions to the math utilities. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3005 8ced0084-cf51-0410-be5f-012b33b47a6e 2009-04-19 10:10:45 +00:00
Attempt to calculate actual refresh rate (i.e. a CPU-GPU synced Mhz), no real success. Anybody have any ideas? Is there no indication from the game when the screen refresh should occur? No, not what I could find, we currently calculate the refresh rate and m_VBeamPos from the CPU ticks progress. That works perfectly if the CPU and GPU is perfectly synced as in the single core and no-idle skipping mode. So I guess it's possible that the game doesn't indicate when the screen should be refreshed, but rather that the hardware calculate that from the CPU ticks progress. That leaves us with a problem in the dual core and idle skipping modes to calculate a CPU-GPU synced CPU ticks progress. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3447 8ced0084-cf51-0410-be5f-012b33b47a6e 2009-06-15 04:30:02 +00:00			`// Calculate sum of a float list`
