Another night behind me and I'm getting close to new release. There are some glitches where beams flips (those bright dots and jaggies) and the bugs when editing SSP are not taken care of yet, but whole brand new beam based simulation (rather then ray based) is done. I've also fixed some bugs in intensity, now I'm few orders closer to simple spherical spreading if I try to simulate it.
All random numbers are gone, all non-covered pixels are gone.
Small delta time now only improves bending simulation, not coverage.
Delta angle can be no much higher (I use 5 degrees now !). There are two mechanisms which allows it. First I have beams with non-zero width now, and beam is divided into more if it gets too wide. Like this I can use small count of beams where it is not important and more beams where it is needed. All this can of course be controled by user.
Also interference simulation got better because of better coverage.
Here is quick peek of actual results .. note that delta angle is 5 degrees and delta time is 0.01s !
Other things I'd like to make yet (tomorrow I hope):
- fix known bugs (thanks to all for reports)
- Session save/load (options,ssp)
- individual rays overlay - you will be able to specify another delta angle (let's say 10 degrees) and individual rays will be displayed at this angles, with full intensity (and different colors), so you can see what the sound is doing.
- Intensity overlay - you will be able to display intensity for given depth as graph where intensity will be on Y axis (logarithmic scale)
Possible changes:
- logarithmic display of brightness (not during the simulation, but after it).
- better spline function for SSP definition to allow linear gradients and better control.
