Transform 3D

Parameters

Name	Type	Description
Valueoutput	Transform 3D	The input transform with the stack applied on top.
Input Transform	Transform 3D	A transform to start from. Leave it unconnected to start from nothing.
Angle Unit	Enum	The unit every angle in the stack is written in.Choices: Degrees, Radians, Turns
Operation Type	Enum	What Add Operation adds.Choices: Translate, Scale, Rotate (Euler), Rotate (Axis Angle), Look At
Add Operation	Trigger	Adds an operation of the chosen type to the bottom of the stack.

Operations

The stack, applied from the top down. Each entry is one operation.

Translate

Name	Type	Description
Translation	Vector 3	How far to move along each axis.

Scale

Name	Type	Description
Scale	Vector 3	The factor along each axis. 1 leaves an axis as it is.

Rotate (Euler)

Name	Type	Description
Order	Enum	The order the three axis rotations are applied in.Choices: XYZ, XZY, YXZ, YZX, ZXY, ZYX
Rotation	Vector 3	The angle around each axis.
Pivot	Vector 3	The point the rotation turns around.

Rotate (Axis Angle)

Name	Type	Description
Axis	Vector 3	The direction to rotate around. Its length does not matter.
Angle	Float	How far to rotate around the axis.
Pivot	Vector 3	The point the rotation turns around.

Look At

Name	Type	Description
Target	Vector 3	The point to aim at.
Up	Vector 3	Which way is up, used to keep the result upright.
Forward Axis	Enum	The axis that is pointed at the target.Choices: -X, +X, -Y, +Y, -Z, +Z

Transform 3D describes where something sits in 3D space as a stack of simple steps: move it, turn it, scale it, or aim it at a point. A stack like this is easier to read and adjust than a single matrix. The operations are applied from the top down, so the first one acts on the geometry first. A new operator starts with a scale, a rotation and a translation, in that order. The buttons in an operation’s header move it or remove it.

The stack is applied on top of the input transform. Chaining two of these operators therefore gives the same result as one operator with both stacks in order.

Look At turns the geometry so that its forward axis points at the target. It keeps the up direction as upright as it can. It aims from the operation’s own origin, so a translation earlier in the stack changes what is looked at.

Use it to place a mesh with Transform, or animate one by connecting signals to the translation and rotation.
