Degree to Rotation in an expression.

[Kel Solaar]

Hello!

I'm trying to find a way to link an object axis rotation to some parameters of a shader: Basically I would like to drive a VRay shader VRayEnvImage.fhrotation ( Ranging from 0 to 360 ) to the Y rotation of an object ( Ranging from minus a lot to a lot . At some point the object can have a rotation of -457 degrees, I need to fit that in range from 0 to 360 dynamically through an expression.

In Python I would do that:

Code: Select all

def degreeToRotation(value):
	rotation = value
	while rotation >= 360:
		rotation -= 360
	while rotation < 0:
		rotation += 360
	return rotation
	
print degreeToRotation(-1620)

Some help would be much appreciated!

Cheers,

KS

Could be that I am misunderstanding the question, but wouldn't a simple
"fmod(<val1>,<val2>)" (modulo operation) suffice, where <val2> equals 360 (or maybe 360.0)?

Hi Hirazi!

You know there are moments in life when you feel stupid, well that's one of those, dunno where to hide really

Cheers mate

Code: Select all

def degreeToRotation(value):
	return value % 360
