Spherical Distort

The Spherical Distort plugin uses an input projection mode to map an image into coordinates on a sphere and then unmaps it back into a destination projection mode.

Overview

The Spherical Distort plugin supports fish eye, perspective, latitude/longitude, cube face, and cylindrical projection models. The tool allows conversion between any of the models.

Input

• Blend Radius - Blends the edges of the input image.
• Field of View - Perspective images are usually somewhere between 30 and 70 degrees. Fisheye images can have fields of view up to 360.
• Field of View Type - Defines the axis where the field of view is defined.
• Angular Blend Radius - Increase this parameter to blend the circumference of the fisheye image.
• Fisheye Distortion File - Incorporate data measured during a Fisheye Lens Calibration.
• Image Width/Height - The desired size of the output image
• Supersampling - This parameter increases the quality of the sampling to preserve more detail during distortion. Supersampled images will require more memory to process.
• Rotation Controls - Used to rotate the sphere before outputting the image.
• Rotation Mode - Controls the order in which modifiers are applied
