I want to make an image plane appear with the following animation:

  1. image plane is invisible
  2. a pie slice of the plane becomes visible
  3. The pie slice increases so as to reveal more and more of the image plane in a clockwise (or anticlockwise) motion
  4. image plane is completely visible

Trying to come up with a clue I toyed around with the screw modifier, which does offer the animation I want, but then any image texture I apply to it is majorly deformed. I'd want to see the image as is.

How can this be done in Blender? Thanks in advance for any thoughts!

Edit the material so you can animate a radial texture to drive the transparency. Set the Gradient to Radial for a clock wipe effect. Use a math node set to Snap to step through the reveal in segments instead of a continuous wipe.

Notice that in Eevee you must set the material's alpha type to blend or hashed.

Wipe with radial texture

    $\begingroup$ Went with this solution in the end, because I could do the animation within a single object. Thanks for the answers! Learnt a lot from both $\endgroup$

You could create a simple edge, give it a Screw modifier, and enable the Visibility > Holdout option so that it create a transparent mask in front of your image. Then enable the Render > Film > Transparent option:
