# collision(3)

## NAME

Collision detections between scene geometry -

## Detailed Description

### Classes

class **SoIntersectionDetectionAction**\
 *The* **SoIntersectionDetectionAction** *class is for detecting intersecting primitives in a scene.*

Note that only collisions between actual geometry in the scene is detected, so the contents of some special nodes like e.g. **SoText2** and **SoImage** (which projects to screen-plane bitmap graphics, and not actual polygons) will not be considered for collision detection. **"**
