Gradient Input

[Exper]

E' da quasi un anno che stò mantenendo sul Forum NT un Thread che riguarda i Gradienti (Gradient Input).

Il Thread è ora chiuso, almeno sino alla prossima versione di LW!

Gradient Input update needed:

SDK

• Add "Gradient Input" Class to SDK.
  
• Add an "Empty"-Type/Class under the "Gradient" type of control so that programmers can create new gradient types (http://vbulletin.newtek.com/showthre...437#post211437)

New ones - Surfacing

• Surface Tangent Slope supports negative slopes by mirroring the positive slope values (http://amber.rc.arizona.edu/lw/newshades)
  
• Surface Normal Slope uses the slope of the surface normal vector rather than the surface's tangent. It also supports negative slopes, but using the normal's slope gives a continuous gradient for an input range of -1 to 1 (http://amber.rc.arizona.edu/lw/newshades)
