3d Vector Sea Maps

[danics]

Hi everybody,
i ask this question here because i don't know where i can ask it.
i m want work on 3d vector sea maps, i find this MapMedia Charts, i see your powerful software and cm93 parser of your code, i want to know how can i parse and draw these maps?
can you show me some article or sample code for working with these maps?
thanks a lot, and sorry for asking here

danics...
By "these" you mean which ones? CM93 or MapMedia? If CM93, refer to the opencpn source code. If MapMedia, well, good luck, we don't know anything about their format.

so I think CM93 v3, i need 3d vectors rendering and algorithms.
thanks.

danics...
The format of CM93v3 and it's encryption schema is proprietary and unknown to us. You have to talk to Jeppesen about it.

Ok, so if you have any other suggestion for me in working with 3d vectors, i would be thankful.

[seandepagnier]

It should be relatively straightforward to render 3d vector graphics is opengl mode.

Do you know the internal format of these charts? From where can they be obtained?

[danics]

I need 3d vectors of sea maps, like .mm3d or Mediamap or cm93 v3

[Baikal]

It would be great to have the function of displaying maps in 3D

Of objects format S-57 can take the values ​​of XYZ feature vertices
1. Coastline, Land Area Z = 0
2. Depth Conour = - Z = Value of Depth Conour
3. Sounding = - Z = Value of Sounding

From XYZ data can be constructed surface by triangulation networks

Hi all.

I am quite new in this forum and very interested in opencpn. So hopefully this is the right task to place an additional question regarding other chart formats:
Is anybody busy with implementing a plugin to handle JEPPESEN CMAP MAX/PC charts?
Is there an "official" way from opencpn community to get in contact with companies like Jeppesen to ask for support?

Thank You!

Some time ago (2012) HotRod reported on the (negative) policy of Jeppesen regarding open software:

You might contact him if you like to speak to Jeppesen directly.

And please report back about the response you get. You can sent me a PM as well.

Hello all!! Cm93 3D map are not specially detailed to where I use to go fishing. I have connected my GPS and Furuno Sounder and have created a DB with lat, long and deep. Is there any way to plot this in 2D or 3D?

alejandroh...
How many points are you talking about? Hundreds? Thousands? Tens of thousands?

Pavel

[alejandroh]

Thousands or even hundred of thousand

[nohal]

For small thousands, you can create a GPX layer from your data. For hundreds of thousand the performance of such solution will be unsatisfactory and there's nothing better right now.
