function

const LazyFunction* blender::nodes::GeometryNodesGroupFunction::function = nullptr

The lazy-function that does what the node group does. Its inputs and outputs are described below.

geometry_outputs

input_usages

IndexRange blender::nodes::GeometryNodesGroupFunction::input_usages

A boolean for every group input that indicates whether this input will be used. Oftentimes this can be determined without actually computing much. This is used to compute anonymous attribute lifetimes.

main

IndexRange blender::nodes::GeometryNodesGroupFunction::main

Main input values that come out of the Group Input node.

Main output values that are passed into the Group Output node.

output_usages

IndexRange blender::nodes::GeometryNodesGroupFunction::output_usages

A boolean for every group output that indicates whether that output is needed. It's ok if those are set to true even when an output is not used, but the other way around will lead to bugs. The node group uses those values to compute the lifetimes of anonymous attributes.

range

[struct]

struct { ... } blender::nodes::GeometryNodesGroupFunction::references_to_propagate

Some node groups can propagate attributes from a geometry input to a geometry output. In those cases, the caller of the node group has to decide which anonymous attributes have to be kept alive on the geometry because the caller requires them.
