Module picking 

Ray-cast object picking.

Structs

GpuPickHit

Result of a GPU object-ID pick pass.

PickHit

Result of a successful ray-cast pick against a scene object.

ProbeBinding

Per-object attribute binding for probe-aware picking.

RectPickResult

Result of a rectangular (rubber-band) pick.

Functions

box_select

Select all visible objects whose world-space position projects inside a screen-space rectangle.

pick_rect

Sub-object (triangle / point) selection inside a screen-space rectangle.

pick_scene

Cast a ray against all visible viewport objects. Returns a PickHit for the nearest hit, or None if nothing was hit.

pick_scene_accelerated_with_probe

Like pick_scene_accelerated but also computes the scalar value at the hit point.

pick_scene_nodes

Cast a ray against all visible scene nodes. Returns a PickHit for the nearest hit.

pick_scene_nodes_with_probe

Like pick_scene_nodes but also computes the scalar value at the hit point.

pick_scene_with_probe

Like pick_scene but also computes the scalar attribute value at the hit point via barycentric interpolation (vertex attributes) or direct lookup (cell attributes).

screen_to_ray

Convert screen position (in viewport-local pixels) to a world-space ray.
