(

Target

type

)

Member Function Documentation

void IndexedBuffer::bind

(

GLuint

bindingPoint

)

Bind this buffer to the specified binding point in the OpenGL context.

Buffer type must be AtomicCounter, TransformFeedback, Uniform or ShaderStorage.

Parameters

bindingPoint

Binding Point

glBindBufferBase

getBindingPoint()

isBound()

GLuint IndexedBuffer::getBindingPoint ( ) const

inline

Returns

Binding point which the buffer is currently bound to (result is undefined if isBound() returns false).

See also

isBound()

bool IndexedBuffer::isBound ( ) const

inline

Returns

True if this buffer is bound to a binding point (by a call to bindBase)
