Public Member Functions |
| boost::optional< T > | at (const std::size_t pos) const |
| | Read-only access to a specific buffer element.
|
| const Buffer & | buffer () const |
| | Read-only access to the buffer.
|
| boost::optional< T > | operator[] (const std::size_t pos) const |

| void | reset () |
| | Empties the Z buffer.
|
| const size_type | size () const |
| | Returns the buffer size.

Private Attributes |
| Buffer | m_buffer |

|
| TCompare | m_cmp |
| | The comparison operator.

template<typename T, typename TCompare = std::less<T>>
class icl_core::ZBuffer< T, TCompare >
A simple Z buffer implementation. Values are stored inside the buffer only if their corresponding buffer cell is currently empty, or the values are less than the currently stored value (where the meaning of "less" can be defined by a custom operator).
- Template Parameters:
-
| T | The stored type. Elements of the buffer will be of type boost::optional<T>. |
| TCompare | Comparison operator. A stored element is updated with a new element if the comparison m_cmp(new_elem, current_elem) returns true. |
