Hi

When importing a heightmap in MED
the Z-postion has a formula R*1 + G*1 + B*2

I assume this means Red*1 + Green*1 + Blue*2
and is used for heigt calculation.

The problem is that I don't understand this so
if anyone could explain this I would be grateful.

The heightmap file, isnt that a greyscale image
where Red=Green=Blue? So why B*2 ?

Say I have designed a heightmap where white(R=G=B=255)
should be equal to 50 meters and black(R=G=B=0) is 0 meters.
How should the formula look for this scenario?
