Member Function Documentation

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::alloc

(

const Size< Dim > &

_size

)

[inline]

Allocate buffer memory.

size to be allocated

Reimplemented from Cuda::Storage< Type, Dim >.

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::bind

(

GLenum

t

)

[inline]

Bind the buffer object to the given target.

Parameters:

t

target to which the buffer object should be bound

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::connect

(

)

[inline]

Register and map buffer object.

If you called disconnect(), this must be called before using the buffer memory in a CUDA kernel.

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::disconnect

(

)

[inline]

Unmap and unregister buffer object.

This must be called before accessing the buffer memory in OpenGL, e.g., copying the buffer data from or to a texture.

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::registerObject

(

)

[inline]

Register abuffer object.

If you called disconnect() or unregister, this must be called before using the buffer memory in a CUDA kernel.

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::unregisterObject

(

)

[inline]

Unregister buffer object.

This must be called before accessing the buffer memory in OpenGL for writing, e.g., copying the buffer data from a texture.

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::mapBuffer

(

)

[inline]

Map buffer object.

This must be called before accessing buffer memory in Cuda. Note, that the buffer object must be registered in Cuda

template<class Type, size_t Dim>

void Cuda::OpenGL::BufferObject< Type, Dim >::unmapBuffer

(

)

[inline]

Unmap buffer object.

This must be called before read-accessing buffer memory in OpenGL. Note, that the buffer object must be registered in Cuda.

template<class Type, size_t Dim>

static void Cuda::OpenGL::BufferObject< Type, Dim >::unbind

(

GLenum

t

)

[inline, static]

Unbind the buffer object from the given target.

Parameters:

t

target from which the buffer object should be unbound
