P3D v4 P3Dv4 compliant Windobjects

[Christian Bahr]

Hello developers.

A question to the experienced developers in this forum. I would like to re-program my SODE-controlled wind turbines and wind socks to meet the P3Dv4 standard and no longer need SODE. Is it even possible to design my wind objects to be P3Dv4 SDK compliant? And if that should be possible, is this a high amount of time and effort, or do these objects even have to be tweaked? The interface Simconnect is not considered for my question, because I am not a programmer.

To understand: the wind objects should react on the one hand to the wind direction and should turn into the wind. On the other hand, the wind turbines have been animated according to data sheet - the rotor blades rotate according to the RPM specifications of the Enercon data sheets and react differently to the wind.

I'm grateful for any helpful answer.

Hi,

I think you still need a tool like SODE for that. Simple visibility conditions can be done directly in P3D v4 now without SimConnect, but in that way you can't access the wind variables.

But the question is: how to do it without SODE?
There must be a way (or not? ), it is just that we have not found it yet!

Thanks Arno.

Well, I had already solved the question of SODE-controlled wind objects satisfactorily - everything worked flawlessly.
But now it's about figuring out which alternative method, besides SODE, makes the wind objects dynamic. The question was answered in such a way that there probably is no P3Dv4 compliant way to control WinObjects according to P3Dv4 SDK.

But somehow there must be a way, because the new technology of SpeedTrees works well!?

Hi Christian:

I do not yet have P3Dv4 to test, and I am not a programmer either; but I am curious:

* Have you been able to discern how the P3Dv4 default Windsock object works ?

* Is there a default Wind Turbine in P3Dv4 that can be analyzed ?


Also, although L-M reportedly intended to expand the required use of SimConnect in the scenery infrastructure of P3D, FSUIPC can access that sub-system.

LUA scripting and Paul Henty's FSUIPC Client DLLs work via FSUIPC; perhaps these may be an alternative way to access pertinent variables ?

The intended P3Dv4 SDK compliant wind objects should work completely without additional modules / tools / programs. They should, if you like, work independently with pure P3Dv4 code - without having to tweak these objects. But apparently there is not this possibility, because in the SDK documentation is nothing to this topic. There is only talk of Simconnect and its variables. Unfortunately, I am not a programmer, otherwise I would have the opportunity to look into the code of the default Windobjects and then possibly transfer this code to my animated wind objects.

Hi

This subject is really interesting because I have one object of a project that happen here at Portugal, (but is not any more active, was a investigation project) and now is beginning to appear all over the world.
When the ocean is to deep to put structures on the ocean floor, they used a special platform to maintain the balance of the windmill.
This type of platforms area already at another places in the world.


This is what I have modulated and animated:

Now I'm facing the wind direction issue. Basically I would separate the object in two and apply SODE on the top part, but I'm not understanding how SODE works. They do not have a simple tutorial.
So, I agree with Christian, it will be nice to provide objects that should work completely without additional modules / tools / programs. But even so, SODE is an amazing achievement. I congratulate them for the product.

You're absolutely right with your words and your assessment, Mário. SODE is just too good to do without. However, there may be certain circumstances that you have to do without SODE. But anyway. In my freeware projects, I will still not do without SODE. It is too valuable for me

Hi Christian!

Do I understand correctly that you have SODE animated wind turbines? One that turns into wind and the rotation speed depends on the wind strength?
I'm looking for some for my scenery, but could not find. And I'm not good in modelling.
Are you willing to share the model?

I already used some of your stuff, like runway lights for pilot controlled lights in SODE and those are fantastic.

Correctly one must say that there are several wind turbines:

- enercon_e40_65m_still.MDL
- enercon_e40_65m_slow.MDL
- enercon_e40_65m_medium.MDL
- enercon_e40_65m_fast.MDL

Depending on the wind speed, the corresponding wind turbine is displayed and then turns into the wind. The wind strengths are defined in the SODE script. But for some time, the wind objects in the Bahrometrix sceneries are controlled by their own wind controller. What specific project is it for which you need the wind turbine?

My idea is simple: placing all the wind turbines in my country (and maybe in more countries). I plan to look up the exact coordinates from different online sources and/or check in google earth and then make a list for SODE. So basically just place them all around the country (and everywhere, depending on my time and dedication to place thousands of objects ).

There is one similar free scenery already, which also contains other types of power plants, but the wind turbines in that scenery have a simple fixed animation, unfortunately. Here it is: https://simviation.com/1/search?submit=1&keywords=ray+porter&x=21&y=11 (FSX Power Project v5.0)

I'm sorry, but I can not provide my wind turbines. Thank you for your understanding.

Sorry to hear that.
It would be only a hobby project, obviously without any commercial plans involved, which I would share with the community later on.
I would actually be proud if someone finds my work worthy to be part of an other project, but I understand you want to protect your work.

Guess I have to learn now how to model an object and how to animate it correctly...
