Radial texture

Back to Distortion textures

The radial texture distorts a piece of an n-ball to an axis aligned box. This distortion is described by the center of the ball and a piece of that ball bounded by an aligned box in spherical coordinates.

Example

The images below demonstrate the usage. Note that in the images below we have also applied a transform-texture to flip and mirror the roles of x and y.

The input image to be distorted as well as the piece of the distortion ball.

The result of applying the radial texture distortion. We used mirroring for the texture extension and EWA filtering for the image resampling.
