To start the project properly, filming something to track our plant models into is the first step. What we did first was go down to the greenhouse we wanted to film and survey the area for any hazards, as well as consider the camera angles we wanted to have for out VFX projects.
The first thing needed before pictures were taken was a Risk Assessment Which I created above. I listed out all the ways that someone could become injured, along with how these risks would be prevented. This is important to do before filming, as without knowing the risks, they can't be prevented.
Once I'd done that, I took some pictures around the greenhouse to try and find a nice angle. The example footage had a pan of the shelf through the window, which I liked, so I tried to replicate that with two ofthe photos.
We ended up going with something more similar to this angle, with the shot starting from far away and panning closer to the shelf through the open doors. We brought down the Black Magic Camera, as well as a plant for reference. We also needed some things to help us integrate the 3D assets into the scene, such as a chrome ball, matte ball and a macbeth chart, which will each give us the correct colour filters and shadows to impose over our models whilst rendering.
Here is a compilation of the footage with the multiple takes we did. It includes shots with and without the plant as reference, as well as tracking printed tracking points that we stuck around the set to make implementing the 3D asset into the scene easier.
The next step is working with this footage in Nuke in order to fix any camera errors, and to prepare the tracking points to be exported into another software to render out a 3D model in the correct position.
