Expression attach Displacement Map Values to an Angle Control effect
Hi
I’m not sure if it’s possible but I’m trying to get the direction in which my Displacement Map is displacing to be linked to an Angel Control effect slider.
So if the Angle Control was set at 90 degrees then my Displacement Map values would be:
Max Horizontal Displacement: 100 (any positive number really)
Max Vertical Displacement: 0
And if it was set to 180 degrees it would be
Max Horizontal Displacement: 0
Max Vertical Displacement: 100
and so on….
Any ideas?
Thanks in advance

Sure, for your example you’d apply this to the horizontal displacement:
amp = 100;
angle = 45 //replace with angle control value here
amp * Math.cos(degreesToRadians(angle)- Math.PI/2);
And vertical displacement:amp = 100;
angle = 45 //replace with angle control value here
amp * Math.sin(degreesToRadians(angle)- Math.PI/2);
I’ve written these from memory and haven’t tested them, so let me know if something doesn’t work.Darby Edelen
