User Manual

Controls Tab
The Controls tab presents various ways to customize or build the lens distortion model you
want. Camera Settings allow you to specify the camera used to capture the content.
Mode
Undistort removes the lens distortion to create a flattened image. Distort brings the original lens
distortion back into the image.
Edges
Determines how samples that fall outside the frame are treated.
 Canvas: Pixels outside the frame are set to the default canvas color. In most cases, this
is black with no Alpha.
 Duplicate: Pixels outside the frame are duplicated. This results in “smeared” edges but
is useful when, for example, applying a blur because in that case black pixels would
result in the unwanted blurring between the actual image and the black canvas.
Clipping Mode
 Domain: Retains all pixels that might be moved out of the frame for later re-distorting.
 Frame: Pixels moved outside the frame are discarded.
Output Distortion Map
Outputs the location of pixels as a warped screen-coordinate map.
Camera Settings
The options known from the Camera 3D are duplicated here. They can either be set manually
or connected to an already existing Camera 3D.
Lens Distortion Model
Select the appropriate 3D Equalizer Lens Distortion model here: 3DE Classic Model, 3DE4
Anamorphic, 3DE4 Radial Fisheye, or 3DE4 Radial. Please consult the 3D Equalizer manual for
further explanation. The sliders in the 3DE Classic LD Model are most likely best suited for
manually applying (un)distortion, without having imported lens data.
Supersampling [HiQ]
Sets the number of samples used to determine each destination pixel. As always, higher
supersampling leads to higher render times. 1×1 bilinear is usually of sufficient quality, but with
high lens distortion near the edges of the lens, there are noticeable differences to
higher settings.
Supersampling Mode [HiQ]
The type of sample done for each supersample. Nearest leads to a crisper but more aliased
image. Bi-Linear gives a blurrier result.
Load Distortion Data
Allows the user to load a Lens Distortion profile created, for example, by the 3D Equalizer.
