geo/PointBuilder

Runs the code nodes inside it once for every point of its first input.

Builder

Dive inside and read point attributes with code/Attribute, work on them with any code node, and write the result back with a code/Attribute whose value input is wired. Several attributes can be written at once.

The first input is the geometry it visits; the three after it are read only. To read one of them, set a code/Attribute's input index to 1, 2 or 3. An input holding points answers the point nearest to the position you give the read (or, under the same-index lookup, the point with the same index as the one being visited), and an input holding a volume is sampled smoothly at that position.

The backend picks where the code runs: on the CPU, or on the GPU as a compute shader. Both give the same result.

Parameters

Name Type What it does
backend UInt8 CPU · GPU Where the code runs: CPU, or GPU as a compute shader. Both give the same result; the GPU wins on large point counts.
