Transform Modifier

modifiers/transform-modifier·v1.5.1

IN:1 OUT:1

SUMMARY

The Transform Modifier translates, rotates and scales each instance, in world space or along the instance's own axes with Local Space, with Rotate Order, Pivot and Uniform Scale controls. On regular POP geometry it behaves like a Transform POP.

Rotate Mode adds to or replaces the existing rotation, Scale Mode multiplies or replaces the scale, and Pivot Mode adds to or sets the pivot, so several Transform Modifiers can be layered in a chain. Do Falloff blends translate, rotate and scale per instance, so it plugs straight into the falloff operators.

PARAMETERS

PAGETransform

Group	Group	If there are input groups, specifying a group name in this field will cause this POP to act only upon the group specified.
Local Space	Localspace	When on, the effect is applied in local space. When off, world space is used.
Do Falloff	Dofalloff	Weight the effect on each point by the Falloff Attribute.
Falloff Attribute	Falloffattr	The point attribute, 0 to 1, that weights the effect.
[+]Translate	T	Translate each instance in the three axes, in the selected space.
[+]Rotate	R	Rotate each instance around the X, Y and Z axes. Angles are given in degrees.
[+]Scale	S	Scale factor for each axis of each instance.
[+]Pivot	P	The pivot point for the rotate and scale of each instance.
Uniform Scale	Scale	Specifies a uniform scale factor for each instance.
[+]Rotate Order	Rord	Sets the order of the rotations of each instance.
[+]Rotate Mode	Rotmode	Determines whether the rotation is added to or replaces the existing rotation.
[+]Scale Mode	Scalemode	Determines whether the scale multiplies or replaces the existing scale.
[+]Pivot Mode	Pivmode	Determines whether the pivot offset is added to the pivot (Add) or overwrites it (Set).

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
Render Primitives	Renderprimitives	Whether to render the full POPX geometry. When off, only point instances are drawn.
Convert to Point Primitives	Converttoptprim	Enable converting points to point primitives when Render Primitives is off.
SRT / RST	Srtrst	Sets the transform order, SRT or RST, used when the points are rendered as TouchDesigner instances.

ATTRIBUTES

IORead

popxFalloff

point float

Falloff attribute controlling where and how strongly the effect is applied (default popxFalloff; set by Falloff Attribute).

IOModified

P	point vec3	Instance position. Offset by the translation (falloff-weighted) and corrected for the pivot.
Orient	point vec4	Instance orientation quaternion. Rotated by the rotate parameters (add or replace), falloff-weighted.
Scale	point vec3	Instance scale. Scaled by the scale parameters (multiply or replace), falloff-weighted.
PointScale	point float	Uniform per-instance scale factor, folded into the scale when scaling is enabled.
Pivot	point vec3	Instance pivot. Set to the target pivot when Do Pivot is enabled (no falloff blend); unchanged otherwise.
Transform	point mat3	Per-instance 3x3 rotation and scale matrix, recomposed from the resolved orientation and scale.
FullTransform	point mat4	Per-instance 4x4 transform with pivot-corrected translation; the matrix used for instancing.
N	point vec3 created if missing	Default POPX geometry normal. Created with a default if absent on input; re-oriented by the instance transform and output (per-vertex for polygon output).
Up	point vec3 created if missing	Default POPX geometry up vector. Created with a default if absent on input; re-oriented by the instance transform and output.
