# SoPrimitiveVertexCache(3)

This cache contains an organized version of the geometry in vertex array form.

## NAME

SoPrimitiveVertexCache - This cache contains an organized version of the geometry in vertex array form.

## SYNOPSIS

\#include \<Inventor/caches/SoPrimitiveVertexCache.h\>

Inherits **SoCache**.

### Public Types

enum **Arrays** { **NORMAL** = 0x01, **TEXCOORD** = 0x02, **COLOR** = 0x04, **ALL** = (NORMAL\|TEXCOORD\|COLOR) }\

## Constructor & Destructor Documentation

### SoPrimitiveVertexCache::SoPrimitiveVertexCache (SoState \* state)

Constructor.

### SoPrimitiveVertexCache::~SoPrimitiveVertexCache () \[virtual\]

Destructor.

## Member Function Documentation

### SbBool SoPrimitiveVertexCache::isValid (const SoState \* state) const \[virtual\]

Return *TRUE* if this cache is valid, *FALSE* otherwise.

Reimplemented from **SoCache**.

### void SoPrimitiveVertexCache::close (SoState \* state)

Closes the cache after it is created. Takes care of **SoGLLazyElement** synchronization.
