Development // 3D Scanning without a 3D scanner
Over the past month, we have had Daniel here on work experience.
During his time here, we set him the challenge of researching and developing a work-flow to capture real life objects in the form of a 3D scan, with the limitation of not having access to a 3D scanner.
The method to do this is called photogrammetry and isn’t anything majorly new to the CGI industry, but it is something that we believe could be a very useful tool to have at our disposal.
Photogrammetry works by taking 100s of photos of a static object, and them loading them into a piece of software which can the turn the 2D images into a 3D object. It’s very very clever, and is mind-blowing to even consider how the software does what it does!
In a nut-shell, photogrammetry isn’t as straight forward as a lot of the manuals say. It cab be very fickle and requires an almost perfect scenario of flat lighting. However we did start to make progress, end with a successful scan of Huddersfield fines dough treats!
Our testing did take longer than anticipated, and the final results (so far) are by no means the end product, but we can certainly see the potential with this tool and workflow.
The advantages of photogrammetry are speed, accuracy and low cost. The downsides are mainly in the uncontrollable side of things such as lighting.
We will continue to develop this part of our work, and can see it being useful for interiors (maybe organic items such as food and soft furnishings) and exterior images for statues or maybe historic architecture.
We owe Daniel a massive thank you for his time with us, and we wish him well in his studies!
