Detailed Description
A block of bytes that stores the actual raw vertex data referenced by a GeomVertexArrayData object.

Member Function Documentation
◆ get_next_block()
|
inline |
Returns a pointer to the next allocated block in the chain, or NULL if there are no more allocated blocks.
Definition at line 55 of file vertexDataBlock.I.
References SimpleAllocatorBlock::get_next_block().
◆ get_page()
|
inline |
Returns the page from which this buffer was allocated.
Definition at line 27 of file vertexDataBlock.I.
References SimpleAllocatorBlock::get_allocator().
◆ get_pointer()
|
inline |
Returns a pointer to the start of the allocated memory for this buffer, or NULL if the data is not currently resident.
If the data is not currently resident, this will implicitly request it to become resident soon.
If force is true, this method will never return NULL, but may block until the data is available.
