Typedefs
typedef map< GLuint, unsigned int >	VuoGlTexturePool
	The number of times each glTextureName is retained.

Functions
GLuint	VuoGlPool_use (VuoGlPoolType type)
	Returns an OpenGL object of type type.
void	VuoGlPool_disuse (VuoGlPoolType type, GLuint name)
	Indicates that the caller is done using the OpenGL object name of type type.
void	VuoGlTexture_retain (GLuint glTextureName)
	Increments the reference count for glTextureName.
void	VuoGlTexture_release (GLuint glTextureName)
	Decrements the reference count for glTextureName.

Variables
VuoGlTexturePool	VuoGlTexturePool_referenceCounts
	The reference count for each OpenGL Texture Object.
dispatch_semaphore_t	VuoGlTexturePool_referenceCountsSemaphore = NULL
	Synchronizes access to VuoGlTexturePool_referenceCounts.

Typedef Documentation

typedef map<GLuint, unsigned int> VuoGlTexturePool

The number of times each glTextureName is retained.

Function Documentation

void VuoGlPool_disuse	(	VuoGlPoolType	type,
		GLuint	name
	)

Indicates that the caller is done using the OpenGL object name of type type.

The object is returned to the pool, so other callers can use it (which is more efficient than deleting and re-generating objects).

This function may be called from any thread.

GLuint VuoGlPool_use

(

VuoGlPoolType

type

)

Returns an OpenGL object of type type.

If an existing, unused object is available, it is returned. Otherwise, a new object is created.

This function may be called from any thread.

void VuoGlTexture_release

(

GLuint

glTextureName

)

Decrements the reference count for glTextureName.

This function may be called from any thread.

void VuoGlTexture_retain

(

GLuint

glTextureName

)

Increments the reference count for glTextureName.

This function may be called from any thread.

Variable Documentation

VuoGlTexturePool VuoGlTexturePool_referenceCounts

The reference count for each OpenGL Texture Object.

dispatch_semaphore_t VuoGlTexturePool_referenceCountsSemaphore = NULL

Synchronizes access to VuoGlTexturePool_referenceCounts.
