Detailed Description

Picking style node.

This node determines how subsequent geometry nodes in the scene graph are to be picked, as indicated by the style and method fields.

Note that this is the only way to change the pick behavior of shapes; drawing style, complexity, and other rendering-related properties have no effect on picking.

FILE FORMAT/DEFAULT

PickStyle {

style

SHAPE

}

ACTION BEHAVIOR

SoRayPickAction, SoCallbackAction
Sets the current pick style and method in the state. Sets: SoPickStyleElement SoPickMethodElement

Member Enumeration Documentation

enum SoPickStyle::Method

Picking method.

Specifying a method will not change the result of picking but may affect performance. Some shapes like MoMeshSkin and SoIndexedFaceSet implement a fast GPU Picking technique that may be faster than CPU picking (depending on the case). When Method is AUTO, Open Inventor will automatically determine which picking method should be used. However you can force using CPU or GPU picking technique. Please refer to SoRayPickAction documentation for more details about GPU Picking.

Enumerator:

AUTO	Select the best method to use when picking a shape.
GPU	Always use GPU accelerated picking if the shape supports it.
CPU	Always use CPU picking even if the shape supports another picking method.

enum SoPickStyle::Style

Picking style.

Enumerator:

SHAPE	Points on the surfaces of shapes may be picked.
BOUNDING_BOX	Points on the surfaces of 3D bounding boxes of shapes may be picked.
UNPICKABLE	Subsequent objects are ignored by pick traversal.
