Patforms and Ships

[dvslats]

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.
A picture from googling.

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!
Dave

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
