K 3.001

Postby Janusz Biela » Wed Jan 09, 2019 9:43 am

We testing now new tone map: tanh
Here are some information about it (not exactly but similar):
http://www.robots.ox.ac.uk/~dre/docs/el ... tj_4yp.pdf

Also we have new scene loader (LW - K3) which is incredible fast (20-40 times faster!). Heavy scenes which took 3-4 min to start now needs seconds....

I have not yet ready images with new tone map but I will upload it soon.

I got more info from G. about new tone mapper:
Tanh_GUI.png
Tanh_GUI.png (10.02 KiB) Viewed 864 times



Here is formula:

Tanh.png


I marked two red dots too see image brightness scale - this what we see.
0,0 means dark (GUI Tanh 0)
1,1 means white (GUI Tanh 1)

Playing with parameter i0 you increase dark regions (negative value like -1, -2, etc)
Playing with parameter i1 you reduce over bright area (value 2,2, etc)


Probably we will have it in GUI interface as graph for tone map.

Yes...from command line right now.
But I send to G. priority request to add save button in next update (soon official release K3.01 - we test now K3.001).
