## NAME

Cache Classes -

### Classes

class **SoBoundingBoxCache**\
 *The* **SoBoundingBoxCache** *class is used to cache bounding boxes.*  class **SoCache**\
 *The* **SoCache** *class is the superclass for all internal cache classes.*

It organizes reference counting to make it possible to share cache instances. It also organizes a list of elements that will affect the cache. If any of the elements have changed since the cache was created, the cache is invalid. " class **SoConvexDataCache**\
 *The* **SoConvexDataCache** *class is used to cache convexified polygons.*

**SoConvexDataCache** is used to speed up rendering of concave polygons by tessellating all polygons into triangles and storing the newly generated primitives in an internal cache. **"** class **SoGLCacheList**\
 *The* **SoGLCacheList** *class is used to store and manage OpenGL caches.*  class **SoGLRenderCache**\
 *The* **SoGLRenderCache** *class is used to cache OpenGL calls.*  class **SoNormalCache**\
 *The* **SoNormalCache** *class is used to hold cached normals.*

**As an extension to the original SGI Open Inventor v2.1 API, it is also possible to generate normals using this class.** "

## Detailed Description

The cache classes are internal to Coin. The Cache Classes The cache classes are mostly internal to Coin.
