thanks M_L...

I've to try all these function may be I'll got something new...

Q: what the 'complement scalar' does ?

NKAID...

'complement scalar'(x) = 1-x

'negate scalar'( 'complement scalar' ) = x - 1
'complement scalar'('negate scalar'(x)) = x+1
'abs scalar'(x) + x = if (x<0) then 0 else 2x (I have a phobia against conditional nodes)

'dot product'([x,y,z], 1) = x + y + z

and due to my phobia:

'subtract scalar'( 'add scalar(x, z) , 'difference_scalar'(x, z)' ) = 2*min(x,z)

Useful if you use the vector version of the above node functions.

Also remember that you can mix vector functions and colour functions witout any trouble.

thank you you are a must ...
except that ['dot product'([x,y,z], 1) = x + y + z] ; that don't sounds well 

[Volker Harun]

Has anybody an idea how to convert the pure displacment information of a heightfield or a fractal terrain into scalars?

That would help me a lot

[FrankB]

Only way I can think of at the moment is to go through "altitude in texture", Volker. have you tried that?

Convert > Y to Scalar ?
Maybe?

[x,y,z] means a vector (or colour) input to the 'dot product' node. Because the 'dot product' node uses to vector inputs,
the scalar 1, is expanded to the vector [1, 1, 1].

The dot product of two vectors [a, b, c] and [A, B, C] is calculated as: [a, b, c].[A, B, C] = a*A + b*B + c*C

  thank a lot ...

This is just a teaser, because I have not seen any new function-images yet

wood grain ! cool

[Henry Blewer]

The wood grain is great. I've been really enjoying your function experiments. I can see a huge group of these available as presets in a future software version. Perhaps under a tab of their own.

[aymenk2003]

that's really  wonderful ... then we can do everything with functions...
back to our old math books and review the artistic function ...
you are great Volker ...
