3D Modelling and Tracking of a Building

For this clip i was inspired by shots included in films where a bomb would land on a building. I decided i wanted to do something similar but not with a bomb as i felt my knowledge of Matchmover and Maya wasn’t advanced enough to create a bomb along with an explosion and debris. So instead i decided it would be different to create a sort of blanket or table-cloth to fall onto a building.

With the use of Matchmover, i tracked all the points of a panning shot of a building on Portland. I then had to take that file into Maya and construct a sort of shell of the building and where all the ledges are etc to give the programme an idea of where the cloth should be dropping and where the shadows should be appearing.

Then i had to create the cloth and i applied a colourful checkerboard design to it. There is also a camera view involved in the video as in the perspective view the construction of the building is visible.

After this i had to render all of the frames out into images which took a very long time. Eventually it had finished rendering and i was able to import all of the images into Adobe Premiere Pro CS6. I had to lower the minimum frame value of stills in the properties to easily create the video without resizing every still, considering there is around 300 of them.

I don’t have a breakdown/any screenshots of the project at the moment i will update this later.

The final video is below.

I am satisfied with the final outcome of the video clip but there are parts i am not as happy with for example there is a small ball in the frames that flies down vertically against the building I believe this is a tracking point and I was under the impression it would be invisible but it is not and I would try my best to change this if I could redo it. Also there are some edges visible and have some shadow around the construction of the building I made, I am not sure why they are visible as I could not see them when i did pre-renders.Soi would need to find out why they are there and how to change that if I wanted to change the clip. I have also noticed that the cloth doesn’t fall where it should on the ground when it gets to the bottom of the frame, I thought I had rectified this and made it so it drops where it should but for some reasonĀ it drops where the steps are so I would need to change this if i had to redo it as well.
