IndirectArrayRegion
(region, size, component_count, component_stride)¶A mapped region in which data elements are not necessarily contiguous.
This region class is used to wrap buffer regions in which the data must be accessed with some stride. For example, in an interleaved buffer this region can be used to access a single interleaved component as if the data was contiguous.
Constructor:
__init__
(region, size, component_count, component_stride)¶Wrap a buffer region.
Use the component_count and component_stride parameters to specify
the data layout of the encapsulated region. For example, if RGBA
data is to be accessed as if it were packed RGB, component_count
would be set to 3 and component_stride
to 4. If the region
contains 10 RGBA tuples, the size
parameter is 3 * 10 = 30
.
