Detailed Description

Inviwo wrapper for OpengL Vertex Array Objects (VAO)

Handles the creation and deletion of OpenGL VAOs. Has functions for attaching and detaching buffer objects. It also keeps track of all attached buffers and corresponding attribute locations.

Note

An OpenGL Vertex Array Object is tied to a render context and only valid within the same render context that was active when creating it.

Member Function Documentation

attachBufferObject()

void inviwo::BufferObjectArray::attachBufferObject	(	const BufferObject *	obj,
		GLuint	location,
		BindingType	bindingType = BindingType::Native )

Attach buffer object obj to a specific location location.

Precondition

The BufferObjectArray must be bound

Exceptions

Exception	if another buffer object is alread attached to location location.
RangeException	if location is invalid. That is location >= maxSize().

attachBufferObjectForce maxSize

attachBufferObjectEnforce()

void inviwo::BufferObjectArray::attachBufferObjectEnforce	(	const BufferObject *	obj,
		GLuint	location,
		BindingType	bindingType = BindingType::Native )

Enforce the attachment of buffer object obj to a specific location location. Overrides any existing binding for this location.

Precondition

The BufferObjectArray must be bound

Exceptions

RangeException

if location is invalid. That is location >= maxSize().

attachBufferObject maxSize

bind()

void inviwo::BufferObjectArray::bind

(

)

const

Bind the VAO

clear()

void inviwo::BufferObjectArray::clear

(

)

Removes all buffer attachments from the VAO

Precondition

The BufferObjectArray must be bound

detachBufferObject()

void inviwo::BufferObjectArray::detachBufferObject

(

GLuint

location

)

Detach the buffer object at location location, if attached, and disable that vertex attribute array.

Precondition

The BufferObjectArray must be bound

Exceptions

RangeException

if location is invalid. That is location >= maxSize().

getId()

GLuint inviwo::BufferObjectArray::getId

(

)

const

Return the OpenGL ID of the VAO

maxSize()

size_t inviwo::BufferObjectArray::maxSize

(

)

const

Return the maximum number of buffers that can be attached to a VAO as supported by the OpenGL hardware. The result corresponds to GL_MAX_VERTEX_ATTRIBS.

Returns

maximum number of buffers that can be attached to this BufferObjectArray

unbind()

void inviwo::BufferObjectArray::unbind

(

)

const

Unbind the VAO by binding id 0
