| Inheritance | IndexBuffer3D  Object |
| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Indices managed by an IndexBuffer3D object may be used to select vertices from a vertex stream. Indices are 16-bit unsigned integers. The maximum allowable index value is 65535 (0xffff). The graphics subsystem does not retain a reference to vertices provided to this object. Data uploaded to this object may be modified or discarded without affecting the stored values.
IndexBuffer3D cannot be instantiated directly. Create instances by using Context3D::CreateIndexBuffer()

Method Detail
dispose | () | method |
public function dispose():void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Free all native GPU resources associated with this object. No upload() calls on this object will work and using the object in rendering will also fail.
uploadFromByteArray | () | method |
public function uploadFromByteArray(data:ByteArray, byteArrayOffset:int, startOffset:int, count:int):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Store in the graphics subsystem vertex indices.
Parameters
data:ByteArray — a ByteArray containing index data. Each index is represented by 16-bits (two bytes) in the array. The number of
bytes in data should be byteArrayOffset plus two times count.
| |
byteArrayOffset:int — offset, in bytes, into the data ByteArray from where to start reading.
| |
startOffset:int — The index in this IndexBuffer3D object of the first index to be loaded in this IndexBuffer3D object. A value for startIndex not equal to zero may be used to load a sub-region of the index data.
| |
count:int — The number of indices represented by data.
|
Throws
TypeError — kNullPointerError when data is null.
| |
RangeError — kBadInputSize when any of count, byteArrayOffset, or startOffset is less than 0,
or if byteArrayOffset is greater than or equal to the length of data,
or if two times count plus byteArrayOffset is greater than the length of data, or
if startOffset + count is greater than numIndices given in Context3D::createIndexBuffer().
| |
Error — 3768: The Stage3D API may not be used during background execution.
|
uploadFromVector | () | method |
public function uploadFromVector(data:Vector.<uint>, startOffset:int, count:int):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Store in the graphics subsystem vertex indices.
Parameters
data:Vector.<uint> — a vector of vertex indices. Only the low 16 bits of each index value are used.
The length of the vector must be greater than or equal to count.
| |
startOffset:int — The index in this IndexBuffer3D object of the first index to be loaded. A value for startOffset not equal to zero may be used to load a sub-region of the index data.
| |
count:int — The number of indices in data.
|
Throws
TypeError — kNullPointerError when data is null.
| |
RangeError — kBadInputSize when count is less than 0 or greater than the length of data, or
when startOffset + count is greater than numIndices given in
Context3D::createIndexBuffer().
