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.

forceIntoRenderTextureShould camera rendering be forced into a RenderTexture.
gateFitThere are two gates for a camera, the sensor gate and the resolution gate. The physical camera sensor gate is defined by the sensorSize property, the resolution gate is defined by the render target area.
layerCullDistancesPer-layer culling distances.
layerCullSphericalHow to perform per-layer culling for a Camera.
lensShiftThe lens offset of the camera. The lens shift is relative to the sensor size. For example, a lens shift of 0.5 offsets the sensor by half its horizontal size.

stereoActiveEyeReturns the eye that is currently rendering. If called when stereo is not enabled it will return Camera.MonoOrStereoscopicEye.Mono. If called during a camera rendering callback such as OnRenderImage it will return the currently rendering eye. If called outside of a rendering callback and stereo is enabled, it will return the default eye which is Camera.MonoOrStereoscopicEye.Left.
stereoConvergenceDistance to a point where virtual eyes converge.
stereoEnabledStereoscopic rendering.
stereoSeparationThe distance between the virtual eyes. Use this to query or set the current eye separation. Note that most VR devices provide this value, in which case setting the value will have no effect.

usePhysicalPropertiesEnable [UsePhysicalProperties] to use physical camera properties to compute the field of view and the frustum.
velocityGet the world-space speed of the camera (Read Only).
worldToCameraMatrixMatrix that transforms from world to camera space.

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.

RemoveCommandBuffersRemove command buffers from execution at a specified place.
RenderRender the camera manually.
RenderToCubemapRender into a static cubemap from this camera.
RenderWithShaderRender the camera with shader replacement.
ResetRevert all camera parameters to default.
ResetAspectRevert the aspect ratio to the screen's aspect ratio.
