PerspectiveCamera class
A standard pinhole-style perspective camera.
Defined by an eye position, a look-at target, an up direction, a vertical field-of-view (fovRadiansY), and a near/far frustum (fovNear/fovFar). The horizontal field of view is derived from the render target's aspect ratio at draw time.
Default placement is at (0, 0, -5) looking at the origin with +Y
up, suitable for inspecting a model that fits within a unit cube
centered on the origin.
Constructors
- PerspectiveCamera({double fovRadiansY = 45 * degrees2Radians, Vector3? position, Vector3? target, Vector3? up, double fovNear = 0.1, double fovFar = 1000.0})
- Creates a PerspectiveCamera.
Properties
- fovFar ↔ double
-
Distance to the far clipping plane. Geometry beyond this is clipped
away. Must be greater than fovNear.
getter/setter pair
- fovNear ↔ double
-
Distance to the near clipping plane. Geometry closer than this is
clipped away.
getter/setter pair
- fovRadiansY ↔ double
-
Vertical field of view, in radians.

- target ↔ Vector3
-
World-space point the camera is looking at.
getter/setter pair
