Description

A Camera is a device through which the player views the world.

A screen space point is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the Camera.

A viewport space point is normalized and relative to the Camera. The bottom-left of the Camera is (0,0); the top-right is (1,1). The z position is in world units from the Camera.

A world space point is defined in global coordinates (for example, Transform.position).

Note that a class must not inherit from Camera directly. If you need to inherit from Camera see ScriptableCamera.

See Also: camera component.

Public Methods

AddCommandBufferAdd a command buffer to be executed at a specified place.
AddCommandBufferAsyncAdds a command buffer to the GPU's async compute queues and executes that command buffer when graphics processing reaches a given point.
CalculateFrustumCornersGiven viewport coordinates, calculates the view space vectors pointing to the four frustum corners at the specified camera depth.
CalculateObliqueMatrixCalculates and returns oblique near-plane projection matrix.
CopyFromMakes this camera's settings match other camera.
CopyStereoDeviceProjectionMatrixToNonJitteredSets the non-jittered projection matrix, sourced from the VR SDK.
GetCommandBuffersGet command buffers to be executed at a specified place.
GetGateFittedFieldOfView Retrieves the effective vertical field of view of the camera, including GateFit. Fitting the sensor gate and the resolution gate has an impact on the final field of view. If the sensor gate aspect ratio is the same as the resolution gate aspect ratio or if the camera is not in physical mode, then this method returns the same value as the fieldofview property.
GetGateFittedLensShift Retrieves the effective lens offset of the camera, including GateFit. Fitting the sensor gate and the resolution gate has an impact on the final obliqueness of the projection. If the sensor gate aspect ratio is the same as the resolution gate aspect ratio, then this method returns the same value as the lenshift property. If the camera is not in physical mode, then this methods returns Vector2.zero.
GetStereoNonJitteredProjectionMatrixGets the non-jittered projection matrix of a specific left or right stereoscopic eye.
GetStereoProjectionMatrixGets the projection matrix of a specific left or right stereoscopic eye.
GetStereoViewMatrixGets the left or right view matrix of a specific stereoscopic eye.
