Inheritance diagram for Wizt::GLPixelBuffer:
Public Member Functions | |
| GLPixelBuffer () | |
| Do not initialize size, this is deferred to save_pixels() which is caching size and pbo. | |
 Public Member Functions inherited from MemCore::ReferenceBase< PixelBuffer > | |
| auto | getObjectCountID () const noexcept |
| Get a unique ID for this object in the given domain. | |
| bool | isIdentical (const WeakPtr< PixelBuffer, PixelBuffer > &PossibleSelf) const noexcept |
| Check if this object is identical to the one used by the given pointer. | |
| void | mkAutoDestructive () |
| Marks this object as being automatically destructed, e.g. | |
| refcount_t | refcount () const noexcept |
| The strong reference count. | |
| ReferenceBase (PixelBuffer *that) noexcept | |
| Constructor, initializes reference counter to zero. | |
| const auto & | self () const |
| Return weak pointer to the object self. | |
| refcount_t | wrefcount () const noexcept |
| The weak reference count. | |
Additional Inherited Members | |
| Public Types inherited from MemCore::ReferenceBase< PixelBuffer > | |
| using | reference_domain_t = PixelBuffer |
| The type of the base class. | |
| using | SelfPtr_t = WeakPtr< PixelBuffer, PixelBuffer > |
| Type for a pointer to this object itself. | |
| Protected Member Functions inherited from MemCore::ReferenceBase< PixelBuffer > | |
| virtual void | extremeUnction () |
| A virtual function that will be called just before the object is destroyed. | |
| ReferenceBase & | operator= (const ReferenceBase &R) |
| Protected assignment operator (should not be called). | |
| void | suicide () |
| Delete this. | |
| virtual | ~ReferenceBase () |
| Virtual destructor. | |
Detailed Description
PBOs allow to perform asynchronous pixel data transfers.
Instead of directly reading the texture data, copy it into a buffer object, which can be accessed asynchronously.
