    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.

    Ports

    Name Direction Type Description
    In Input Vector 3 Input value
    Out Output Vector 3 Output value

    Controls

    Name Type Options Description
    From Dropdown Object, View, World, Tangent, Absolute World Selects the space to convert from
    To Dropdown Object, View, World, Tangent, Absolute World Selects the space to convert 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 = In;
    

    World > Object

    float3 _Transform_Out = TransformWorldToObject(In);
    

    World > Tangent

    float3x3 tangentTransform_World = float3x3(IN.WorldSpaceTangent, IN.WorldSpaceBiTangent, IN.WorldSpaceNormal);
    float3 _Transform_Out = TransformWorldToTangent(In, tangentTransform_World);
    

    World > View

    float3 _Transform_Out = TransformWorldToView(In)
    

    World > Absolute World

    float3 _Transform_Out = GetAbsolutePositionWS(In);
    

    Object > World

    float3 _Transform_Out = TransformObjectToWorld(In);
    

    Object > Object

    float3 _Transform_Out = In;
    

    Object > Tangent

    float3x3 tangentTransform_World = float3x3(IN.WorldSpaceTangent, IN.WorldSpaceBiTangent, IN.WorldSpaceNormal);
    float3 _Transform_Out = TransformWorldToTangent(TransformObjectToWorld(In), tangentTransform_World);
    

    Object > View

    float3 _Transform_Out = TransformWorldToView(TransformObjectToWorld(In));
    

    Object > Absolute World

    float3 _Transform_Out = GetAbsolutePositionWS(TransformObjectToWorld(In));
    

    Tangent > World

    Tangent > Tangent

    float3 _Transform_Out = In;

    Tangent > Absolute World

    View > Object

    float3 _Transform_Out = TransformWorldToObject(mul(UNITY_MATRIX_I_V, float4(In, 1) ).xyz);
    

    View > Tangent

    View > View

    float3 _Transform_Out = In;
    

    View > Absolute World

    float3 _Transform_Out = GetAbsolutePositionWS(mul(UNITY_MATRIX_I_V, float4(In, 1))).xyz;
    

    Absolute World > World

    float3 _Transform_Out = GetCameraRelativePositionWS(In);
    

    Absolute World > Object

    float3 _Transform_Out = TransformWorldToObject(In);
    

    Absolute World > Tangent
