Re: OpenCPN Beta test 4.1.602 Release

Re: OpenCPN Beta test 4.1.602 Release

Hello Dave,

I am searching a new version of NV-Verlag plugin to test my NV-Verlag chart with O 4.1.602.

Is it exist ?

best regards. Gilletarom

I didn't think about the setup flag, but you did the right thing.

So.. yes it works then 100% of the time? I don't really like this turd but I am also not sure of any other way to deal with it.

Should this be added to the master ?
I would say so.

I am also altering glChartCanvass.cpp to disable the stencil buffer every time I get a new version. based on this conversation with Dave:
OpenCPN Runs on Embedded ARM
That was to fix a problem with displaying certain features of ENCs. Perhaps that could be added by checking for MALI graphics ?
Can you find some specific examples? I would rather use the stencil if it can be used.

Can you reproduce it? What did you do? any chance you can bisect to find the offending commit?

boat_alexandra, Dave - please tell me how things are going to correct the error display ENC what I wrote above?

Re: OpenCPN Beta test 4.1.602 Release

Baikal,

I think it's fixed in my projection's branch, at least for opengl. It's course-up quilted ENC correct?

I can not compile your assembly out compilation errors
you can send me opencpn.exe ready for the test?

I will test a bit more to be sure it is fixed and not causing any other problems. Is this because of something that was recently introduced in Ubuntu ?

Yes, this is a problem we talked about before. Some C-Map/ENC features do not display correctly when using the stencil buffer on CubieTruck.
An example with C-Map charts and "Dredged area" is at: 43 17.9088 N 079 47.7904 W just zoom in and out on the bridge ("Dredged area"); Be sure to have that chart feature enabled.
There are other features that cause similar problems as well: Quality Of Data, Unsurveyed Area, and Shoreline Constructions.
I do not notice a performance hit, and there seem to be a few other platforms with Stencil buffer problems, so I was thinking of adding it based on MALI.

I just deleted the texture cache. I will test this further next week, going sailing this weekend.

Cheers,

No. Basically it's as it says in the comment. OpenCPN -> gtk -> cairo -> egl and also at the same time glshim is using egl. Now for our purposes, cairo isn't using egl, but it links with it so it will load it. If we are also loading egl with dlopen then somehow it crashes like what you found. I really don't understand it fully, only that if we render some text really early to a memory buffer, it initializes cairo and the program will never crash. If you know of a better solution let me know.

Maybe a good idea, but also there is probably a workaround to make the stencil buffer work correctly. In any case you will probably only notice a performance hit in obscure cases.

Maybe you can try again now? I fixed some compile problems. Otherwise please post the errors in the projection thread.

Re: OpenCPN Beta test 4.1.602 Release

hi all
the last git don't compile
I get this compilation error :

Thanks for your help

Re: OpenCPN Beta test 4.1.602 Release

Something wrong with your compiler?
sqrt() should be normally double sqrt(double).
But the float or the long double version of sqrt() should be sqrtf() or sqrtl().

My compiler is vs2010 as it always been (Vs2013 is a nightmare!)

Re: OpenCPN Beta test 4.1.602 Release

So perhaps check the include file math.h for informations.

Yes sqrt() could be double or long double or float but not wxCoord !
in the expression in ocpndc.cpp:677
int steps = ceil(sqrt(r));
r is wxCoord type

My workaround is ocpndc.cpp(677):
int steps = ceil(sqrt((double) r));
It compile and works but I don't know if there is negative consequence somewhere
thanks

baikal....

I have been unable to reproduce the problem with rotated, quilted, S57 ENC on OpenGL, Windows platform. See attached screenshot.

Do you have any more information that might be useful?

Thanks
Dave
