This add-on is part of the presentation The Missing Camera or: How I Learned to Stop Worrying and Love Oblique Projection at BCON24.

Usage

• Place cursor.
• Select the desired projection.
  • From the 'Add Camera Menu' ('Shift + A')
  • In the 'Parallel Cams' tool menu ('N' shortcut).
• A camera is created.
• Change projection types and parameters in the 'Redo Panel'
• Modify orthographic scale in the properties' camera tab.

How it works

• Orthographic projections are determined by the camera's position and rotation angle.
• For the oblique projections the X pixel ratio is modified automatically prior to rendering.

References

The add-on is named after Karl Wilhelm Pohlke, author of a generalizing parallel projection theorem in 1853. The cover image is a detail of plate VIII "Palatin" from "L'art de bâtir chez les Romains" by Auguste Choisy (Ducher et Cie, Paris, 1873).
