Camera

Fisheye

RefImgCameraViewFisheye.png

The fisheye projection

Length of direction, up and right are irrelevant. Angle is the important setting and can go up to 360.

omnimax

RefImgCameraViewOmnimax.png

The omnimax projection

Angle is irrelevant. The relative length of up and right are important.

orthographic

RefImgCameraViewOrthographic.png

The orthographic projection

Length of direction is irrelevant unless angle is used. Lengths of up and right define the dimensions of the view. Angle can be used (as long as less than 180) and will override the length of right and up (the aspect ratio between up and right will be kept nevertheless) with a scope of a perspective camera with the same direction and angle.

panoramic

RefImgCameraViewPanoramic.png

The panoramic projection

Angle is irrelevant. The relative length of direction, up and right are important as they defines the lengths of the 3 axis of the ellipsoid. With identical length and orthogonal vectors (both strongly recommended, unless used on purpose), it's identical to a spherical camera with angle 180,90.

perspective

RefImgCameraViewPerspective.png

The perspective projection

Angle can be used as long as less than 180 and will recompute the length of right and up using direction, while keeping the aspect ratio between up and right.

spherical

RefImgCameraViewSpherical.png

The spherical projection

Lengths of direction, up and right vectors are irrelevant. Angle is the important setting, and it gets two values separated by a comma: the first is the horizontal angle, the second is the vertical angle. Both values can reach 360. If the second value is missing, it get half the value of the first.
