Hill Editor

Some useful links

At this moment hill editor isn't the best I've could imagine. I am working on it, to make it more user-friendly. However actually it can provide a lot of fun with creating own hills. Here are my some tips for using hill editor.

First of all you can just simpy type in this values from ceftificates of real hills. Ski jumping hills certificates. Unfortunately, there is a little problem, because there are 3 types of profiles: ICR1992, ICR1996 and ICR2008. It isn't mentioned anywhere in hill certificate, but you can recognize proper hill type very easy. There is a simple algorithm for recognize type of hill's profile.

Hill parameters

Ski jumping hill parameters

Below there is an explanation of hill parameters.

Image Editor Explanation
Some usefull parameters, that doesn't appear in hill editor, but are used in other parameters description
A Highest start gate
B Lowest start gate
E1 End of the staight part of the inrun / beginning of the transition curve
E2 beginning of the take-off table
T Edge of the take-off table
P End of the knoll / beginning of the landing area
K Construcion point
L End of the of the landing area / beginning of the transition curve
U End of the hill (fall line)
Parameters from hill editor
w w Just the K point of the hill
h/n h/n h is vertical distance between T point (edge of the take-off table) and K point and n is horizontal distance between this two points. h/n is just h divided by n, which is some kind of steepness ratio of the hill.
γ gamma Angle of the inrun
α alpha Angle of the take-off table
e e Lenght of the inrun from highest start gate to the beginning of the take-off table
es es Distance between lowest and highest start gate.
t t Lenght of the take-off table
r1 r1 Radius of the transition curve at the beginning of the take-off table
βP beta P Angle at the end of the knoll / beginning of the landing area (blue line on hills)
β beta K Angle at K Point
βL beta L Angle at end of the landing area (angle at HS)
s s Height of the take-off table
l1 l1 Lenght of the curve between beginning of the landing area and K point (important when hill has ICR1992 profile type otherwise it doesn't really matter)
l2 l2 Lenght of the curve between K Point and HS (important)
rL rL Radius of the landing area curve (if hill profile type if ICR1992, then you can write here anthing)
r2L r2L Radius of the transition curve from L to U at L(if hill profile type if ICR1992 or ICR1996, then you can write here anthing)
r2 r2 Radius of the transition curve from L to U at U
