|
|
<DL>
|
|
<DD>glMapObjectBufferATI maps an ATI vertex array object to a ByteBuffer. The old_buffer argument can be null,
|
|
in which case a new ByteBuffer will be created, pointing to the returned memory. If old_buffer is non-null,
|
|
it will be returned if it points to the same mapped memory and has the same capacity as the vertex array object,
|
|
otherwise a new ByteBuffer is created. That way, an application will normally use glMapObjectBufferATI like this:
|
|
<p/>
|
|
ByteBuffer mapped_buffer; mapped_buffer = glMapObjectBufferATI(..., null); ... // Another map on the same buffer mapped_buffer = glMapObjectBufferATI(..., mapped_buffer);
|
|
<p/>
|
|
Only ByteBuffers returned from this method are to be passed as the old_buffer argument. User-created ByteBuffers cannot be reused.
|
|
<p/>
|
|
The version of this method without an explicit length argument calls glGetObjectBufferATI internally to
|
|
retrieve the current vertex array object size, which may cause a pipeline flush and reduce application performance.
|
|
<p/>
|
|
The version of this method with an explicit length argument is a fast alternative to the one without. No GL call
|
|
is made to retrieve the vertex array object size, so the user is responsible for tracking and using the appropriate length.<br>
|
|
Security warning: The length argument should match the vertex array object size. Reading from or writing to outside
|
|
the memory region that corresponds to the mapped vertex array object will cause native crashes.
