alRemapFloat by Anders Langlands, Jens Kafitz









The alRemapFloat Node is a powerful Value Remapping Node, giving same results as alRemapFloat Node for Arnold (part of alShaders by Anders Langlands).


Node Overview


Node Ports


Supplies the map you want to adjust


The value that is defined as Minimum Value on the Input. For example on a gradient black to white, when increasing the OldMin

any incoming Value below OldMin will become black. If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


The value that is defined as Maximum Value on the Input Color. For example on a gradient black to white, when decreasing OldMax

any incoming Value above OldMax will become white.If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


A value to adjust the Contrast.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


The Pivot Point for Contrasting. Larger values than the pivot wil get 'crunched' towards white, lower values towards black

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


Bias the Input higher or lower. Values less than 0.5 push the average lower, values higher than 0.5 push it higher.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


Adds gain to the Input, in effect a different form of contrast. Values less than 0.5 increase the gain, values greater than 0.5 decrease it.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


The value that is defined as Minimum Value on the resulting Output. For example on a gradient black to white, when increasing NewMin

the previously black areas will be the value set in NewMin.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


The value that is defined as Maximum Value on the resulting Output. For example on a gradient black to white, when decreasing NewMax

the previously white areas will be the value set in NewMax.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated



Node Properties

Old


The value that is defined as Minimum Value on the Input. For example on a gradient black to white, when increasing the OldMin

any incoming Value below OldMin will become black.


The value that is defined as Maximum Value on the Input Color. For example on a gradient black to white, when decreasing OldMax

any incoming Value above OldMax will become white


Contrast


A value to adjust the Contrast.


The Pivot Point for Contrasting. Larger values than the pivot wil get 'crunched' towards white, lower values towards black


Value


Bias the Input higher or lower. Values less than 0.5 push the average lower, values higher than 0.5 push it higher.


Adds gain to the Input, in effect a different form of contrast. Values less than 0.5 increase the gain, values greater than 0.5 decrease it.


New


The value that is defined as Minimum Value on the resulting Output. For example on a gradient black to white, when increasing NewMin

the previously black areas will be the value set in NewMin.



The value that is defined as Maximum Value on the resulting Output. For example on a gradient black to white, when decreasing NewMax

the previously white areas will be the value set in NewMax.


Clamp


When checked, the Output of the Node will be clamped to Min and Max


When enabled, it will expand the clamped range back to 0-1 after clamping.
