Techvis is the process of using 3D assets to perform technical analysis on a scene or set. It is an important element in virtual production and has become increasingly popular in recent years as filmmakers continue to explore new ways to create stunning visuals with less time and money. In essence, techvis helps filmmakers make informed decisions when creating their projects by providing detailed information about camera type, lenses, rigging, stunts, portions of sets that need to be physically built versus virtual, and more.
Techvis experts must have a deep understanding of the tools used for producing 3D models such as Blender and Maya, as well as proficiency in game engines like Unreal Engine and Unity. As such, a great techvis specialist needs both creative and technical skills to get the job done effectively. Furthermore, they should possess excellent communication skills so they can accurately interpret instructions from directors and art department personnel and provide feedback to better inform the workflow.
For those looking to utilize techvis in their productions, there are a few tips worth considering:
1. Consider the best way to display 3D data during pre-production. This could mean having drawings available at all times, utilizing storyboards to communicate ideas, or setting up playback systems like Ncam Reality.
2. Make sure your team has a good understanding of how rendering works, so they know what kind of resolution and texture quality will be needed for a certain shot.
3. Have everyone involved in the project collaborate early on, especially the director, VFX supervisor, and techvis experts. This will help ensure everyone is on the same page throughout the production process.
4. Invest in technology if you can afford it. For example, Ncam Reality lets filmmakers see their work in real time without any delay, which significantly speeds up the process.
Ultimately, techvis is a valuable tool that allows filmmakers to quickly and efficiently create beautiful visuals while staying within budget constraints. By leveraging the expertise of dedicated professionals and the latest technological advancements, filmmakers can easily realize their visions with confidence.
