Why we like it

Pohlke earns its place for turning parallel-projection camera setup into a one-click operation in Blender. Version 2.0.0 came from a complete rewrite of the codebase, and the add-on can be cited from Zenodo for academic work.

What is Pohlke?

Pohlke is a Blender add-on from developer mononym that creates standard axonometric and oblique projection cameras in one click. Place the 3D cursor, then add a Pohlke camera from the 'Pohlke' tool menu (the N shortcut) or by selecting 'Pohlke Camera' in the add menu (Shift + A). After the camera is created, projection presets and parameters can be changed in the 'Adjust Last Operation' panel.

Axonometric projections are determined by the projected axis angle pairs, while oblique projections automatically modify the X pixel ratio prior to rendering. Version 2.0.0 adds alpha and beta angle parameters for custom projections, a scale info display of axis reduction factors for x, y and z, a projection mode toggle between axonometric and oblique, quick toggles between Above and Below views, quadrant selection, and live parameter updates that reposition the camera in real time in the 3D Viewport.

The add-on is named after Karl Wilhelm Pohlke, author of a generalizing parallel projection theorem from 1853. It's compatible with Blender 4.2 LTS and newer, released under the GNU General Public License v3.0 or later, and can be cited from Zenodo for academic work.

Who is Pohlke best for?

Pohlke is best for blender users who need axonometric or oblique projection cameras set up in one click and adjusted through angle parameters.

How much does Pohlke cost?

Pohlke is completely free to download and use.

Key features

  • One-click creation of standard axonometric and oblique projection cameras, added from the tool menu (N) or the add menu (Shift + A)
  • Axonometric projections determined by projected axis angle pairs; oblique projections automatically modify the X pixel ratio prior to rendering
  • Alpha and beta angle parameters for freely defining custom projections
  • Scale info displaying axis reduction factors (x, y, z) dynamically while adjusting angles
  • Projection mode toggle between axonometric (orthogonal) and oblique modes
  • Quick toggles between Above and Below views, with quadrant selection to orient the view
  • Live parameter updates with real-time camera repositioning in the 3D Viewport

Frequently asked questions

Which Blender versions does Pohlke work with?

Pohlke is compatible with Blender 4.2 LTS and newer, according to the developer's listing. If you're on an earlier release, you'll want to update Blender before installing. The add-on is distributed as an extension you can drag and drop into Blender or download and install from disk, and it declares that it requires no special permissions. For the current compatibility range and any newer builds, check the developer's page at pohlke.rtfd.io.

How do I add a Pohlke camera in Blender?

Pohlke adds a camera in a few steps: place the 3D cursor, then either open the 'Pohlke' tool menu using the N shortcut or choose 'Pohlke Camera' from the add menu with Shift + A. Once the camera is created, you can change projection presets and parameters in the 'Adjust Last Operation' panel. Version 2.0.0 also brings live parameter updates, so the camera repositions in real time in the 3D Viewport as you adjust settings.

Is Pohlke free to use?

Pohlke is listed here as free and is released under the GNU General Public License v3.0 or later. The extension states that it requires no special permissions in Blender. Licensing terms can change, so for the current license details and download options it's best to check the developer's page. You can drag and drop the add-on into Blender or download it and install from disk to get started.

What changed in Pohlke 2.0.0?

Pohlke 2.0.0 is a substantial update built on a complete rewrite of the codebase for better modularity and maintainability. It adds alpha and beta angle parameters for defining custom projections, a scale info display of axis reduction factors for x, y and z, automatic camera rotation and altitude computation, a projection mode toggle between axonometric and oblique, quick toggles between Above and Below views, and quadrant selection. Live parameter updates reposition the camera in real time in the 3D Viewport.

What's the difference between axonometric and oblique modes in Pohlke?

Pohlke supports two projection approaches. Axonometric projections are determined by the projected axis angle pairs, while oblique projections automatically modify the X pixel ratio prior to rendering. Version 2.0.0 adds a projection mode toggle so you can switch between axonometric (orthogonal) and oblique modes directly, along with alpha and beta angle parameters to define custom projections. A scale info readout shows the resulting axis reduction factors for x, y and z as you adjust the angles.
