So hangouts will be best in the morning or evening? Saturday morning ~10:00 would be good for me, what about you guys?
Fun fact: mandelbulber sucessfully compiles in raspbian on raspberry Version b. Performance is
Poor, really poor. But nice that it works :smile:

Saturday morning is OK for me.
Is this Raspberry with ARM cpu?

@buddhi1980 can you quick take a look at last commit, i broke the distance cakculation somehow, but i cannot See the error
Krzysztof Marczak
@buddhi1980
Dec 01 2015 16:45
Ok, I will look
Krzysztof Marczak

This is strange, but it works for me. It renders image properly. Where distance estimation is affected? Maybe I am checking wrong thing.
Sebastian Jennen
@zebastian
Dec 01 2015 16:57
It affects all settingsfiles
I already deleted INI file, no effect seither

So when you render something you can see only backgroung. Is it correct?
Sebastian Jennen
@zebastian
Dec 01 2015 17:01
Yes, if it is only me, then its probably some caching thing. I will try to clean up and repull project...

@buddhi1980

it could be
everything looks ok for me
what you can check is line 33 in mandelbulber2/src/fractparams.cpp
there should be: analitycDEMode = container->Get<bool>("analityc_DE_mode");
I'm asking about this line, because you touched it

Will check, i have a pi Version b Revision which runs a broadcom CPU with armv6

Another problem is in lights.hpp, where in line 46 QObject is not initialized
should be: cLights(const cLights& _lights) : QObject()

fixed it the hard way with:
rm -r mandelbulber
git reset --hard
now it works correctly

Great! I woried that we had some hidden bug in the code.
Sebastian Jennen
@zebastian
Dec 01 2015 18:03
Me too, i thouhht i broke the code with random light commit.

the smooth cursor movement is quite slow to adopt, if the camera is near to the surface
check aexion001.fract while rendering move cursor
smoothLastZMouse += (z - smoothLastZMouse > 0 ? sqrt(z - smoothLastZMouse) : -sqrt(smoothLastZMouse - z)) * 0.01;
i thought we can change smooth calculstion to the above, this will converge faster to end size than before
Krzysztof Marczak
@buddhi1980
Dec 01 2015 18:25
during rendering it adopts much slower than when it's idle
where this is the code?
Sebastian Jennen
@zebastian
Dec 01 2015 18:28
this is the idea
smoothLastZMouse += (z - smoothLastZMouse > 0 ? sqrt(z - smoothLastZMouse) : -sqrt(smoothLastZMouse - z)) 0.01;
the code is
smoothLastZMouse = smoothLastZMouse + (z - smoothLastZMouse)
0.01;
in /rendered_image_widget.cpp line 200

let me see how it works
there is almost no difference
Krzysztof Marczak
@buddhi1980
Dec 01 2015 18:43
it tends to oscillate
Sebastian Jennen
@zebastian
Dec 01 2015 18:43
Yes, it just converges faster
how do i get oscillation?
Krzysztof Marczak
@buddhi1980
Dec 01 2015 18:46
this oscillation is small but visible when cursor has almost destination size
Sebastian Jennen
@zebastian
Dec 01 2015 18:50
now i see
Sebastian Jennen

I will look for a different way to do this...
