    Patforms and Ships

    Hi All,

    I've been trying to understand these notes from the .cfg files from CFS2 ships.

    [platform.0]
    ; platforms are the actual surface that the planes
    ; land on. You can define as many platforms as you
    ; want by adding subsequent sections with increasing
    ; numbers. e.g. [platform.1], [platform.2] etc.
    ;
    ; vertices should be defined in model coordinates,
    ; and counter-clockwise order when viewed from above.
    : REMEMBER, positive z is out to the TAIL of the ship
    ; the shape may be concave or convex
    ; there may be from 3 to 20 vertices (limitation
    ; may go away later) and they must all be on the same
    ; plane.

    vertex.0=10.880001,16.896,-117.376007
    vertex.1=-12.416,16.896,-117.632004
    vertex.2=-12.672001,16.896,-106.624008
    vertex.3=-13.824001,16.896,-81.408005
    vertex.4=-13.952001,16.896,-49.152004
    My brain is not cooperating. How is a platform created with only three numbers.
    Vertices are the items I do not understand.

    DV, looking at the diagrams and the notes from the cfg files it looks like each vertex has a length, width and height. I assume that the height is above sea level. Is it the case that the platform would have 4 sets of 3 vertices? That looks like the platform has a minimum (if it is rectangular) of 12 vertices or one set of 3 for each corner. I may be way off here but that's how it looks to me.

    I think your explanation helped clear some of my head fog Ravenna.
    Off to give it a try.
    Thank You!

    platforms

    can I put my 5 cents worth in here ?

    think of a vertex as a point in space - in its simplest form a platform ( ie a flight deck ) must have four vertices - one for each corner of the flight deck - the three numbers are the coordinates of each point

    width is + or - from the centre line of the deck, left or right
    height is height above sea level ( 0 = sea level )
    length is forward or backward along ship centre line from the centre point ( 0, 7.5, 0 )

    vertex.0=3,7.5,-3 ( width, height, length )
    vertex.1=3,7.5,-22
    vertex.2=-3,7.5,-22
    vertex.3=-3,7.5,-3

    width of the flight deck is 3 + 3 = 6 - the deck / platform is 6 metres wide
    height is 7.5 above sea level
    length is -3 -22 = 25

    hope this is helpful and I haven't bored you into sleep

    Baldy,

    I feel the same way when trying to explain how to convert boost and atmospheres into inches of mercury when adjusting engine data in an airfile.

    Thanks for the five cents Baldy. Every bit helps and this with Ravenna's info has it all clear now.
    I made a graphic for reference. I'll post it here for future help.



    Appreciate all of the help gents.
    Cheerz,
    Dave
