Unity Products:Amplify Shader Editor/Transform Direction

Transform Direction node

The Transform Direction node transforms a given direction vector between different spaces.

Node Parameter	Description	Default Value
From	Current space from which input vector is on. Object Space: Sets input direction space to Object space World Space: Sets input direction space to World space View Space: Sets input direction space to View space Tangent: Sets input direction space to Tangent space	Object Space
To	Space for the position to be transformed to. Object Space: Sets output direction space to Object space World Space: Sets output direction space to World space View Space: Sets output direction space to View space Tangent: Sets output direction space to Tangent space Clip: Sets output direction space to Clip space	Object Space
Inverse TBN	To transform from tangent to another space an inverse TBN matrix(Tangent,Binormal,Normal) must be calculated. Inverting matrices in an heavy operation but in this transforms case it can be simplified at the cost of some precision loss. (Only shown on when From is set to Tangent). Fast: More performant but less precise inverse TBN matrix generation. Precise: Inverse TBN matrix generation created through fully mathematical matrix inversion operation.	Fast
Normalize	Do a Normalize operation over the final calculated vector.	False
Input	Direction vector in selected input space to be transformed into selected output space. Only visible if the respective input port is not connected.	0,0,0

Input Port	Description	Type
In	Direction vector in selected input space to be transformed into selected output space.	Float3

Output Port	Description	Type
XYZ	Returns the transformed vector in the specified space.	Float3
X	Returns only the X component of the transformed vector in the specified space.	Float
Y	Returns only the Y component of the transformed vector in the specified space.	Float
Z	Returns only the Z component of the transformed vector in the specified space.	Float
