Mapping
The Mapping node transforms the input vector by applying translation, rotation, and scaling.
Inputs
The inputs of the node are dynamic. In particular, the Location input is only available in the Texture and Point vector types.
| Entry | What it does |
|---|---|
| Vector | The vector to be transformed. |
| Location | The amount of translation along each axis. |
| Rotation | The amount of rotation along each axis. XYZ order. |
| Scale | The amount of scaling along each axis. |
Properties
Vector type
The node applies the transformation differently depending on the semantic type of the input vector.
Point
For this vector type, the node performs a straightforward transformation.
Transforming a texture coordinates is analogous to transforming a UV map. For instance, translating the texture coordinates along the positive X axis would result in the evaluated texture to move in the negative X axis, much like if one translated a UV map. Similarly, scaling the texture coordinates up would result in the evaluated texture to scale down. So transforming the texture coordinates would appear to have the opposite effect on the evaluated texture.
The order of transformation is: Scale –> Rotate –> Translate, which means:
Translation moves the input along the local rotation axis.
Rotation rotates the input around the origin of the space.
Scaling scales the input along the global axis.
Texture
For this vector type, the node performs an inverse transformation.
Inverse transforming a texture coordinates would, as opposed to the Point type, transform the evaluated texture itself. For instance, translating the texture coordinates along the positive X axis would result in the evaluated texture to move in the positive X axis, as one would expected. Similarly, scaling the texture coordinates up would result in the evaluated texture to scale up, as one would expect.
The order of transformation is: Translate –> Rotate –> Scale, which means:
Translation moves the input along the global axis.
Rotation rotates the input around the translation vector.
Scaling scales the input along the local rotation axis.
| Entry | What it does |
|---|---|
| Vector | For this vector type, a Point transformation is performed, but with zero translation. |
| Normal | For this vector type, the node performs the inverse transpose of the transformation and normalize the result. Such transformation ensures correct normals after non-uniform scaling. So this type should be used when transforming normals. |
Outputs
Vector
The input vector after transformation.
Normal
The Normal node generates a normal vector and a dot product.
| Entry | What it does |
|---|---|
| Inputs | Normal: Normal vector input. |
| Properties | Normal Direction: To manually set a fixed normal direction vector. LMB click and drag on the sphere to set the direction of the normal. Holding Ctrl while dragging snaps to 45 degree rotation increments. |
Outputs
| Entry | What it does |
|---|---|
| Normal | Normal vector output. |
| Dot | Dot product output. The dot product is a scalar value. If two normals are pointing in the same direction the dot product is 1. If they are perpendicular the dot product is zero (0). If they are anti parallel (facing directly away from each other) the dot product is -1. |

|---|---|
| Inputs | Vector: Input vector. · Sides: Number of angular elements for tiling. · Roundness: Roundness of the segment coordinate system. |
