Transform Node

Description

Returns the result of transforming the input value (In) from one coordinate space to another. Select drop-down options on the node to define which spaces to transform from and to.

World and Absolute World

Use the World and Absolute World space options to transform the coordinate space of position values. The World space option uses the Scriptable Render Pipeline default world space to convert position values. The Absolute World space option uses absolute world space to convert position values in all Scriptable Render Pipelines.

If you use the Transform Node to convert coordinate spaces that are not for position values, Unity recommends that you use the World space option. Using Absolute World on values that do not represent position might result in unexpected behavior.

Generated Code Example

The following example code represents one possible outcome of this node per Base mode.

World > World

float3 _Transform_Out = TransformWorldToTangent(In, tangentTransform_World);

World > View

float3 _Transform_Out = TransformWorldToView(In)

World > Absolute World

float3 _Transform_Out = GetAbsolutePositionWS(In);
