Attribute To Index

tools/attribute-to-index·v1.5.1

IN:1 OUT:1

SUMMARY

Attribute To Index normalizes an input attribute, or one component such as P(1), over the selected group, remaps a chosen window of it to a number of integer steps, adds a start index and writes the result as an integer point attribute. Points outside the group keep their values.

Point the Instancer's Point Attribute indexing mode at the output attribute to vary instances by falloff, noise, height or any other attribute pattern. Index Steps sets how many variations are produced, and Debug Color shows the index as a grey ramp so the distribution can be checked before instancing.

PARAMETERS

PAGEIndex

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.
Input Attribute	Inputattr	The attribute remapped to index values.
Input Attribute Range	Inputattrrange	Sets the attribute range, minimum and maximum, that is mapped onto the index range.
Index Steps	Indexsteps	Sets the number of index values, which is the number of variations.
Index Start	Indexstart	Sets the first index value.
Output Attribute	Outputattr	Name of the attribute the index is written to.
Debug Color	Debugcolor	Enable addition of a color attribute to differentiate the points by index.

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.
