IRsUnknownCoordinateSystem Interface Reference
Inherits IUnknown.
List of all members.
Detailed Description
Specifies base interface for coordinate system classes. Because coordinate systems are required also outside read/write threads (during rendering) calls must be thread safe. Implemnetations can be sure, that they will NOT be released during procedure calls.

( |
[in] GUID * |
guid, |

[out] RtMatrixf * |
pMatrix | |

) |
| | |
Evaluate coordinate system matrix for specified slot.
- Slots are used to distinguish between various node output connectors for nodes with multiple coordinate systems.
- Slot = port.
- Parameters:
-
| guid | [in] Specifies port/slot ID. |
| pMatrix | [out] Fill matrix with coordinate system. |
- Returns:
- standard HRESULT processing can be applied to returned value.
| HRESULT IRsUnknownCoordinateSystem::GetCoordinateSystemScaling |
( |
[in] GUID * |

|
|
[out] RtVector4f * |
pScalePlane | |
|
) |
| | |
Compute widget scale multiplication plane.
- Widget rendering matrices are multiplied by distance of their centers from this plane.
- This can be used to build coordinate systems that have widget sizes independent on their distance from viewer.
- Parameters:
-
| guid | [in] Specifies port/slot ID. |
| pScalePlane | [out] Fill this structure with plane. |
- Returns:
- standard HRESULT processing can be applied to returned value.
| HRESULT IRsUnknownCoordinateSystem::GetCoordinateSystemViewDependence |
( |
[in] GUID * |
guid, |
|
|
[out] RtBool * |
pbDependent | |
|
) |
| | |
When widget is not view dependent, then some optimizations may take place (like fixation of axes during operations).
- Parameters:
-
| guid | [in] Specifies port/slot ID. |
| pbDependent | [out] Return true, if widget is view dependent. |
- Returns:
- standard HRESULT processing can be applied to returned value.
