![]() If Auto Focus is OFF, the Focal Distance parameter becomes available, and the camera focuses at the Focal Distance value. The valid range is 0.5 to infinity.Īutomatically focuses the camera on the camera’s View point. Lets you set the camera’s f-stop by typing in any value. Large F-Stop values (such as 32) tend to give a larger depth of field. That means that the region at the specified distance from the camera that is in focus (the region between near and far) is small. Small F-Stop values (such as 1.4) tend to give a very small depth of field. ![]() Lets you set the camera’s f-stop either from a list of standard, real world f-stops (between 1.4 and 32), or by entering a value in the User F-Stop field ( user). The depth of field calculation is a post-rendering process, and can take from tens of seconds to a few hours, depending on the size of the image, the camera parameters, and the depth values, but not the complexity of the scene.īecause depth of field changes with depth, your scene must reflect its real world size and the Main Units must be set properly in Preferences > Construction options (under Units : Linear). The default setting is OFF (no depth of field calculation is performed all objects are in focus). If Depth of Field is ON, the following parameters become available: F-Stop, and User F-Stop. Makes the renderer perform a depth of field calculation to vary the focus of objects based on their distance from the camera. If you change the Film Back values, the Angle of View value automatically changes.If you change the Focal Length value, the Angle of View value automatically changes.If you change the Angle of View value, the Focal Length value automatically changes (and switches to user defined if it is not already).The Angle of View value is related to the focal length value (either the Focal Length setting or the User Focal Length value), and the Film Back value: It represents the width of the film back as seen through the lens, expressed as an angle. The angle of view is also known as the lens angle. For example, doubling the Perspective Gain value will double the speed at which you can dolly the camera. Perspective GainĬontrols the speed at which you can dolly a perspective camera. For example, if you change the X Up value to 2, the Twist value automatically changes to -63.435. The Up and Twist parameters define the same camera property in different ways. The tilt of the camera (from side to side) in degrees. If you do edit these parameters, display the camera in the orthographic windows to help visualize the changes. Positioning a camera by editing these parameters may be difficult, and is not recommended for positioning orthographic cameras. Each parameter has three fields, corresponding to the XYZ coordinates for that parameter. Eye, View, Upĭetermines the camera’s view by defining the camera’s position ( Eye), view point or focal point ( View), and up vector end point ( Up). You can also produce this auto clipping behavior by editing the SDL file and setting the near clipping plane value to 0.Ĭlipping planes are ignored during raytracing. Makes the renderer automatically compute the near and far clipping planes (based on the bounding boxes of the objects in your scene) so that they include all visible objects in the current view frame.īy turning on Auto Render Clip, you can prevent certain types of image quality problems that can be caused by inappropriately set clipping planes.ĭo not turn on Auto Render Clip when you are using shadow maps or if you are outputting depth files during rendering. The default setting is OFF (the camera is not locked). This can be useful when working with image planes. Locks the camera in place so that you are not able to dolly, track, or move the camera in any way. If you change the name of a camera, the name in the camera’s window (in the title bar) also changes. You can type in this field to change the name of the camera. The Twist and Perspective Gain parameters are only available for perspective cameras. The Camera Properties control the position and orientation of the current camera.
