Thought I might experiment with Blender’s Camera Mapping technique that I watched from one of the video tutorials made by Peerless Productions. The link to the video tutorial can be found here . The Blender wiki tutorial can be found here.

Or something like that.

The top image I took from the rooftop of the Car Park in North Main Street. The bottom image is my attempt at re-creating the environment in 3D using the image as a reference in Blender.

With a rough 3D representation of the elements inside the image I then mapped the image onto the 3D scene through the 3D Camera perspective. After animating the camera movement and rendering the output, I got this result.

Aside from the obvious artefacts, the effect looks pretty good. The process itself can take quite a while but I find the results seem to pay off in the end. We’re definitely using it as an FX shot in the upcoming Cork Christmas Carol.
