• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSXA Attach a platform and export as FS2002 GP?

Hi guys,

I'm wondering if the method written in the title works? I designed a sloped terrain and I want to attach a platform to it and export it as FS2002 Ground Polygon not FSX (SCASM not XML).

Any ideas please?
 
AFAIK, a "Platform" must be utilized via a "AttachPoint" on a 3D model in a non-legacy "MDL" format, so that would not be applicable to the legacy SCASM Ground Polygon texturing scenario you describe as your goal. :pushpin:


The method of converting a 3D model to sloped flatten via MCX to be draped in FS at run time with high resolution custom textures (as custom photo-real land class synthetic and/or aerial imagery) using FS SDK Resample ...is likely to be easier to achieve, as recently discussed here:

http://www.fsdeveloper.com/forum/threads/sloped-terrain.436134/#post-732211.


However, it may be possible to utilize a type of legacy format Ground Polygon method with an accompanying shape-matched and underlying terrain flatten shape which is 'sloped' rather than 'flat' (basically a Vector Textured Polygon draped on top of a sloped flatten). :idea:

IIUC, the legacy SCASM methods may allow assigning varying elevation values to all vertices of a textured Ground Polygon object, while still properly maintaining the texture "drape" in FS at run time.

https://www.google.com/#safe=strict&q=SCASM+"TexPoly"


IIRC, Arno stated that a "sloped Ground Polygon" option may be possible in a future release of MCX. ;)

http://www.fsdeveloper.com/forum/threads/ground-poly-wizard-terrain-issues.432939/


I think it is likely that Arno may be able to successfully implement such a method in MCX. :wizard:


FYI: There have been some prior experiments in doing this via SBuilder for FS9 as a SCASM-coded "photomesh" in which a HeightMap / HeightField terrain mesh is 'draped' with a custom photoreal texture image.

http://www.ptsim.com/forum/viewtopic.php?p=2446


BTW: Implementing this method with sloped terrain to create a "photomesh" beyond the rather low-resolution of LOD-8 was apparently not further pursued by SBuilder author Luis Sa' before he began developing SBuilder for FSX (aka "SBuilderX").




Perhaps the most successful implementation of this legacy "High Resolution" Photoreal VTP scenery method (on 'flat' terrain) may have been achieved by the renowned Gottfried Razek of the Blue Sky scenery project in the Tucson, AZ scenery package:


Tucson, Arizona, High-Resolution Scenery - Part 1: Tucson Intl. Airport (KTUS) = tus2008_hr.zip

http://library.avsim.net/esearch.php?CatID=fs2004scen&DLID=127560


He recommends using this in a Scenery Library layer 'above' his lower-resolution photo scenery:

FSX/FS2004 Tucson Arizona Photo-Scenery (AZ) = TUS2008_LR

http://simviation.com/1/search?submit=1&keywords=TUS2008_LR&categoryId=&filename=Y


PS: One might wonder whether de-compilation of "TUS_S4_SHR.BGL" into SCASM source code with BGLAnalyze version 3.1 may prove particularly informative ? :scratchch


[EDITED]

IIUC, to attempt display of the GPs placed by the above file in FSX et seq., one would have to convert Area16N flatten code for the 64 TexPoly GP tiles into equivalent LWM2 / LWM3 or CVX vector flattens.

[END_EDIT]


Also, info by Gottfried Razek on toggling Ground Polygon display via user aircraft altitude: :teacher:

Hope this information helps with the learning process ! :)

I'm really sorry for the late reply! :oops:
Since I registered at FSDeveloper, you were always helping me. Your help is much appreciated. I love your explanation, I can't thank you enough, Gary :)
 
Why scam , you can créate a sloped platfom and just place it with any obejct placement tool. by the way interesting what GaryGb comment about the sloped polygon as a possible new feature in MCX.
