Clarisse 5.0 Reference Guide

Cameras are items simulating a lens that defines the viewpoint from which the scene is rendered. In the same way there are different type of lenses, there are also many types of cameras and each one defines a projection according to the simulated lens.

Perspective Camera

The Perspective Camera simulates a basic pinhole camera which is controlled by a single attribute Field of View. It is possible to enable depth of field by toggling Enable Dof attribute. Depth of field is controlled using the F Stop attribute and the focus can be either set using Focus Distance or a Focus Object. In order to take depth of field into account in the render, make sure it is enabled properly in the renderer.

Perspective Advanced Camera

The Perspective Advanced Camera, as its name suggests, complements the Perspective Camera by offering more advanced controls over the projection. Please note that Alembic and USD cameras both offers the same attributes as Perspective Advanced Camera since they both inherit from it.

Field of View/Aperture

There are different ways to control the field of view of the projection. It can either be achieved by manipulating the aperture and the focal length of the lens or by modifying the field of view attributes. Both sets of attributes are linked together. If you manipulating the aperture and focal length attributes it will recompute the field of view attributes. In the same way, if you modify the field of view attributes, it will update the aperture and focal length ones.

Attribute

Description

Horizontal Aperture

Define the horizontal size (width) of the camera sensor

Vertical Aperture

Define the vertical size (height) of the camera sensor

Focal Length

Define the focal length of the lens

Horizontal Field of View

Define the horizontal field of view of the projection

Vertical Field of View

Define the vertical field of view of the projection

Film Offset

The Film Offset attribute defines the offset of the camera sensor to the lens.

Lens Ratio

The Lens Ratio attribute defines the amount the lens compresses the image horizontally. It basically affects the pixel aspect ratio of the render.

Fit Mode

The Fit Mode attribute allows you to have control over the the pixel aspect ratio of the rendered image.

Fit Mode

Description

Horizontal

Perform a horizontal fit on the rendered image.

Vertical

Perform a vertical fit on the rendered image.

Remap

Stretch the pixel aspect ratio so that both horizontal and vertical field of views fit in the rendered image resolution.

Fill

Automatically perform an horizontal or vertical fit on the rendered image.

Fish Eye

The Fish Eye Camera simulates a fish-eyes type lens which is controlled by a single attribute: Field of View.

Orthographic

The Orthographic Camera defines an orthographic projection. The projection of the camera is controlled by the size attribute which defines the area of the projection. The projection also takes into account the scale of the camera which modifies the pixel aspect ratio. Since there's no front and back culling, it is recommended to use the Near Clip and Far Clip attributes of the render scene/layer 3D to avoid overlaps.

Panoramic

The Panoramic Camera defines an panoramic projection which can render the scene in 360 degrees. This camera can be used to create HDR probes from a scene or for VR applications since it supports multiple stereoscopic modes and users can control parallax. The projection of the camera is controlled by the horizontal and vertical field of views.

 

Paroramic Camera

Paroramic Camera

Attribute

Description

Horizontal Field of View

Define the horizontal field of view of the projection

Vertical Field of View

Define the vertical field of view of the projection

Stereoscopic Mode

Enable stereoscopic rendering. See Stereoscopic Modes section for more information

Eye Separation Distance

Define the distance between the two eyes.

Parallax Mode

Enable the off axis mode. For more information please refer to Parallax section.

Parallax Distance

Set the parallax distance.

Parallax Object

Set an item which defines the parallax distance.

Stereoscopic Modes

The Panoramic Camera supports stereoscopic projections which makes it useful for VR applications. Stereoscopic modes are controlled using the Stereoscopic Mode and Eye Separation Distance attributes. It is also possible to define the master eye for camera projections using stereoscopic cameras by going to Edit > Preferences... > Rendering and setting Projection Master Eye to either Left or Right.

Mode

Description

Center

Stereoscopic rendering is disabled.

Side By Side

Left and right eye images are rendered side by side

Over Under (R/L)

Right and left eye images are rendered on top of each other (right eye image being on top of left)

Over Under (L/R)

Left and right eye images are rendered on top of each other (left eye image being on top of right)

Left Eye

Render the left eye image

Right Eye

Render the right eye image

Parallax

By default the projection of the two eyes are parallel to each other. It is possible to control the focus point by setting Parallel Mode to Off-Axis and setting either the Parallel Distance to the camera or a Parallel Object which acts as the focus point.
