OpenCPN Beta test 4.1.1108 Release

[bcn]

Night mode and the Draw PI:

your opinions needed -

drawn objects are not dimmed. Feature or "not so nice"?

All chart types? OpenGL?

Thanks

I don't think the busy cursor had anything to do with O.
Yesterday I had the problem every time I restarted O. This morning, after a restart of my laptop, the busy cursor is gone.
Sorry for the red herring!

To get the chart loaded, edit it with a hexeditor and replace LAMBERT CONFORMAL CONIC with MERCATOR and blanks...

What problem are you solving by doing this? Please explain. I believe it will defeat some important logic if you specify the wrong projection.

They should be maximum contrast, at least by option. So the user can specify a dimming value maybe, but to make them most visible they should have the maximum brightness for whatever color then use a black background.

The "right" way to allow docking of any PlugIn is to modify the PlugIn so that it's windows become wxAUI clients, like Dashboard does. When that is done, the control windows and/or dialogs can float as they do now, or dock if desired.

This is a relatively simple modification, using Dashboard as a sample instance to study.

Perhaps the best thing to move this forward is a Feature Request against the Radar PlugIns....

Thanks, but, is this the method that Sean mentions as "orthogonal to any goal of decoupling opencpn from a specific widget library such as wxwidgets" ?
Perhaps Orthogonal but expedient ?

Cheers,
JM.

Several charts from US NOAA are in Lambert Conformal Conic projection. OpenCPN refuses to display these charts.

Regarding texture cache I wonder if this is really necessary. I have a lot of RNC charts because I try to work O hard to expose problems. My texture cache is reported as 10.9GB. Is it really worth it to have texture caching with such a large set of data?

I presume we have this feature for hardware platforms that are less powerful from a graphics standpoint. But can these low power systems afford such huge cache files?

Go to Options->Display->Advanced->Options (next to OpenGL selection). There you will find a button to manually rebuild the texture cache.

Thanks, ..Its greyed out.

Sounds like you may be running with the Windows GDI Generic OpenGL driver. This will cause Texture caching to be disabled, since this OpenGL driver is not very compatible with the standard. It is missing several functions we need, and is known to be very slow.

Have you changed your configuration lately?
Please post your logfile entries for OpenGL, and we will take a look.

Have not changed it to my knowledge.

Attached Log file shows its using HD Graphics which is inccorrect!

It should be using Nvidia Geforce 540m adapter.
-Perhaps I should update the HD Graphics drivers now anyway? v8.15.10.2342 from 2011 search on drivers says it is up to date.

Collapse/Expand GRAPHICS INFORMATION
Graphics Product [1] Intel®HDGraphics3000

Current Graphics Resolution 1920x1080

Apparently no updates to this graphics.
I saw it is "OpenGL 4.0"

I am going to change back to the Nvidia Geforce GT 540M

Just an idea but has anyone tested these to see if they are indeed an image actually calibrated to the projection advertised in the header? My experience with old Canadian bsb/kaps indicates that the header is not necessarily an accurate descriptor of the calibration. (ie: mine advertise as NAD27 but are in fact calibrated to wgs 84. )

It would need extracting the image and testing as to proportional size and shape....

I have some UTM , TMs and Poly's I can play with....

Regarding the Radar window docking.

"Expedient" is the word. We are soon going to release Version 4.2.

Any plan to move OCPN away from wxWidgets display base is longer term, and has no real design nor resource allocation yet. Lots of questions here, but the main one in my mind is: "What if user doesn't have OpenGL, for whatever reason."

Since wxWidgets 3.0 is now used also for Windows and Linux some more people see these warnings in their logs:

9:24:39 AM: Warning: iCCP: known incorrect sRGB profile
...
9:24:40 AM: Warning: iCCP: known incorrect sRGB profile

Reason is the newer png library in wxWidgets 3.0 and OpenCPN still use outdated png images.

Raster texture cache is pretty important. Generating the multiple scaled chart tiles (mipmaps) from raw .KAP files is very CPU intensive. Without caching, this would have to be done on every chart load, in real time.

Of course, it is your machine. If a user values disk storage over runtime performance, the option to disable caching is available....

Most of the little ARM boards can have a 64G SDcard and some even have SATA.

The caching certainly gives a huge performance improvement on these boards, but it is clearly broken at the moment.

re:

.

If OCPN does not display the chart, it means that he does not know how to georef the specified projection. He doesn't "try to get close enough", whatever "close enough" might be.

Modify the chart .KAP file to trick O into showing the chart, and all bets are off. Playing with fire here.....

But, as we say, YMMV.

Thanks

re:

Multiple Dashboards:
The mouse right click  view/hide check boxes are not working.

No problem here on Win7.

Anyone else tested this?

Thanks

All along I've been using the NVIDIA program to set the application to use the NVIDIA Card, this utility no longer seems to be working. Have tried it several times.
