Function documentation
Magnum:: Trade:: CameraData:: CameraData(CameraType type,
Rad fov,
Float aspectRatio,
Float near,
Float far,
const void* importerState = nullptr) explicit noexcept
Construct a camera using a field of view.
Parameters | |
---|---|
type | Camera type |
fov | Horizontal field-of-view angle |
aspectRatio | Horizontal:vertical aspect ratio |
near | Near clipping plane |
far | Far clipping plane . Set to Constants:: |
importerState | Importer-specific state |
The constructor converts the fov
and aspectRatio
to near plane size using the following formula and stores that:
The type
parameter has to be CameraType::
Magnum:: Trade:: CameraData:: CameraData(CameraType type,
const Vector2& size,
Float near,
Float far,
const void* importerState = nullptr) explicit noexcept
Construct a camera using a projection size.
Parameters | |
---|---|
type | Camera type |
size | Size of the near clipping plane |
near | Near clipping plane |
far | Far clipping plane. Set to Constants:: |
importerState | Importer-specific state |
For CameraType::near
and far
is expected to be 0.0f
.
Vector2 Magnum:: Trade:: CameraData:: size() const
Size of the near clipping plane.
For CameraType::
Rad Magnum:: Trade:: CameraData:: fov() const
Field-of-view angle.
Expects that type() is CameraType::
Float Magnum:: Trade:: CameraData:: aspectRatio() const
Aspect ratio.
const void* Magnum:: Trade:: CameraData:: importerState() const
Importer-specific state.
