Look at this painting, The Courtyard by Irvine Peacock:

enter image description here

As you can see, there is a sort of fish-eye effect here so that the lines curve, so that you can see more of the image. How can I recreate this effect?

    $\begingroup$ I havent tried it with the blender camera but in real life you would use an extremely short focal length lens IE 12mm or 9mm. You maybe able to fake it using a Lattice. $\endgroup$ – Dontwalk Nov 7 '17 at 19:26

    $\begingroup$ In the camera settings switch from Perspective to Panoramic. It will work only on render. $\endgroup$ – Jaroslav Jerryno Novotny Nov 7 '17 at 20:41

You may achieve it using Fisheye Equisolid type of the Panoramic camera (with some manual vertices tweaking). enter image description here

Add a camera and position it verticaly as pictured below. Add a plane and place it in front of it. Add a background image (display axis type: Camera), decrease its opacity and push the Front button. enter image description here

Set the render resolution so it is the same as image's resolution. enter image description here

Enter the camera view (Ctrl+Num 0) and rotate it along the Z axis to fit the plane to the reference. Extrude the plane until you you build the rough representation of the object from the picture.
enter image description here

Select the extruded object in Object Mode and give it a material (Emission e.g.). Also give it a Wireframe Modifier with some thickness. enter image description here

In Cycles go to Camera Data header--> Lens panel and set the camera type to Panoramic (Fisheye Equisolid). Experiment with Lens and Field of View values. In this case I found Lens=14 and FoV=180 optimal. enter image description here

Divide the 3d view into two windows. Set the Solid viewport shading mode for the first and Rendered for the second one. enter image description here

Snap the cursor to the origin point of the plane. Grab the camera and translate it along the Z axis. Next rotate it along the local Y axis (press R, then double tap Y) to fit the image as precisely as you can.
enter image description here

Controling two views at the same time you can now easily make the subdivisions to the mesh and model the details. enter image description here

To make the model exactly fit the reference's perspective you may tweak some vertices. enter image description here enter image description here

Here's the comparision between original and tweaked perspectives. enter image description here
