A typical conversation we have with our clients is about 3D content creation. Even though 3D content creation is becoming more and more democratized, much like video, we’re still talking about a form of media traditionally produced by expert artists.
Read on to learn more about the different ways people are creating and capturing 3D models of their products.
3D modeling and 3D scanning: the two primary means of building 3D assets
3D modeling: building a model from scratch
3D modeling or CAD (Computer-aided design) refers to the creative process of building a model in three dimensions (known as x,y,z) using a dedicated software package like Maya, Houdini, Blender, Cinema 4D, or many others.
Photogrammetry is a method for capturing an object or space in 3D by taking digital photographs of it from many different angles and processing this image set into a single asset using dedicated software.
Structured light scanning
This method uses a combination of the calibrated hardware, often handheld, to project various patterns of light onto the subject and simultaneously measure the deformations in the pattern as it hits surfaces at different angles using synchronized cameras.
Laser Scanning & LiDAR
Most commonly used in the survey and building information modeling (BIM). Laser scanning or light detection and ranging (LiDAR) is a 3D scanning technique that works by firing thousands of laser beams from a central station and then measuring the time it takes for each beam to bounce back off the in-range environment.
