DataBufferDataT Method (T, IntPtr, DataBufferUsage)

Create and initialize a buffer object's data store.

Namespace: Ooogles
Assembly: Ooogles (in Ooogles.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

public void Data<T>(
	T[] data,
	IntPtr size,
	DataBufferUsage usage = DataBufferUsage.StaticDraw
)
where T : struct, new()

Public Sub Data(Of T As {Structure, New}) ( 
	data As T(),
	size As IntPtr,
	Optional usage As DataBufferUsage = DataBufferUsage.StaticDraw
)

public:
generic<typename T>
where T : value class, gcnew()
void Data(
	array<T>^ data, 
	IntPtr size, 
	DataBufferUsage usage = DataBufferUsage::StaticDraw
)

member Data : 
        data : 'T[] * 
        size : IntPtr * 
        ?usage : DataBufferUsage 
(* Defaults:
        let _usage = defaultArg usage DataBufferUsage.StaticDraw
*)
-> unit  when 'T : struct, new()

Parameters

data: Type: T
data array to copy to the buffer.
size: Type: SystemIntPtr
size of the data in bytes.
usage (Optional): Type: OooglesDataBufferUsage
(optional) expected usage pattern of the data store. Defaults to StaticDraw.

Type Parameters

T: the type of data in the data array

Exceptions

Exception	Condition
GLException	InvalidValue if size is negative.
GLException	InvalidOperation if no buffer is bound.
GLException	OutOfMemory if the GL is unable to create a data store with the specified size.

Remarks

Any pre-existing data store is deleted.

usage is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store.

Note: clients must align data elements consistent with the requirements of the client platform, with an additional base-level requirement that an offset within a buffer to a datum comprising N be a multiple of N.

Note: in DEBUG mode with assertions enabled, an error will be logged to the debug console if this buffer is not bound.
