Photogrammetry available in Vancouver location.
Los Angeles  and 
is a 3D scanning company in the entertainment industry that specializes in the creation of photo-realistic digital assets. Many characters, vehicles, cars, sets, props, 
animals, sculptures, and other items have been added to our scope of work since inception in 2009. 

Our team knows how to work with producers, directors, coordinators, A-list talent, and other agencies, making the most of their precious time and ensuring a successful project. TNG's work is always guaranteed. We are also highly noted for our ability to travel at a moments notice for a project. Exclusive use of highly mobile scanning systems allow for TNG to perform scans in practically any location.


TNG Building

Can you believe we are deep into June? This year needs to slow down, especially now going into summer.  Some one told me I need more balance in life so I think maybe some beach time would be in order.  However, I am about my business and if that is going strong, the beach will always be there.
I wish all of you a wonderful summer and time with your families and loved ones. That said, don't miss E3 (this week)  or Siggraph. Shows always bring out the kid in me.
At TNG, we are developing more techniques in relation to 3D scanning to give you better models. We are getting deeper into developing cars and products to expand our markets with our high-tech scanners, skilled modelers, and our mobility. 

We are always researching new technology and software to keep the quality of our service at the highest level, and to accelerate our pipeline. We do our best to provide a great product to our customers. 

We continue our search for partners who are synergistic to our service. Together we can help our customers save more while using better products. Contact us

Digital Characters on the Move
In order to have a visual effect look real on a character, you need an accurate digital representation. 3D scanning is a solution to produce this accurate digital double.

If a character is 3D modeled from scratch the time it can take is weeks to months, and all the meanwhile there may be discussions about the likeness of made-from-scratch model whereas by utilizing the technology that is 3D scanning as long as you can trust the 3D scanning company and their scanners, the likeness shouldn't be debatable as the scan produces a replica of the real thing.

The shapes captured are the shapes that exist in the real world. This is ideal if making a camera transition from a live model to a 3D model for a visual effect such as destroying a character into particles, or enhancing a character with super powers. At times camera cuts might be used in order to avoid having to show a transition, but 3D scanning allows for those transitions to be believable.

3D scanning a character is a fast and easy way to allow for visual effects. If you are telling a story and the character is seen in different outfits, you can have each layer of clothing 3D scanned . The way clothing rests on a character forming wrinkles and gathers is captured very well in scanning whereas to create the illusion of gravity and wrinkles by scratch is quite a challenge, and will frequently look just a bit off - even if the entirety of the piece is great. Is it easier to simulate gravity on clothing, or to capture gravity in action? 3D scanning can provide you with realistic visual effects.

We find that many companies have their modelers working on props and other items which take up resources. The game of production is a race against the clock in most cases. 3D scans will save you time. In addition to clothing being portrayed correctly and realistically in scanning, facial expressions that are scanned can be utilized as blend shapes. The human face has 43 muscles, and when someone adapts an expression like a smile, those 43 muscles are 'expressing' the expression and emotion. To have this data scanned is to imbue your digital characters with the same likeness as anyone you'll come across in the real world.
All The Small Things 

3D scanning small objects requires attention to finesse and technique to ensure accuracy. The edges have to be sharp and defined. The scan coverage should be 100% (top, bottom, sides, front and back) allowing for watertight surfacing in post-processing to turn it into a usable 3D mesh that can be textured and deformed via animations. Small objects tend to have fine details. Preserving these details is the challenge because when utilizing 3D scanning you want to have extremely accurate results which mimic reality.

Photogrammetry is a fascinating method of capturing 3D scans. Pictures are taken from any camera of any object, and the photos are fed through intelligent algorithms, outputting a 3D point cloud which is then surfaced to a 3D mesh. This sounds great, but is not as easy process as it sounds. The settings for a DSLR camera (shutter speed, aperture, ISO, light intensity, focal length, distance from subject, exterior lighting) can vary greatly. 

You'll want to achieve the depths of high fidelity by squeezing out every extra vertex in your point clouds. Depth seems to be an issue for photogrammetry, and so if you're scanning an ear on a human head, you cannot accurately represent that ear - likewise with nostrils, eyes, and any other crevice. These lost shapes are important, and do grant us more life-like illusions. And thus to compliment the photogrammetry, you may want to also 3D scan the same object, and use both data sets at their strongest points.

There are times when your desired object will not capture so easily, and there are methods to help the scanner capture this data. For example a pencil is a small object, and it is thin so it could be hard to capture, whereas if you capture the ground along with the pencil, you'll have more data, and a tighter alignment.

Small objects can result in very low polygon count models because of their small surface area, and so the smaller an object is, the more care that's required to capture it in such a way to ensure its accuracy and high resolution. We want to see things on screen as we know them in real life.
Lidar for those Big Jobs

LIDAR 3D scanning can map out an environment, or be used to scan a large object from all sides. In the film industry, it can be used to capture an entire room's scene with all of its objects in their exact specific location. For use in the recent horror film, The Conjuring 2, we 3D scanned and photographed a room with all of the furniture and objects within it, which totaled to 100 objects.

Utilizing the 3D scan data of the aforementioned room, we created a digital file (a Maya scene) to hold the room files along with all of the object files. Objects are oriented correctly, separated as their own mesh, optimized for hard edges and creases, unwrapped, and finally textured and detailed.

It is important to determine the level of quality you need for any given room environment or object. At first thought you might think that the best quality is needed for everything, but the reality is that productions have budgets and time constraints, and the distance the camera will be from the effects helps realize the needed poly count and fidelity for any given 3D effect. For example, an item that's on the floor and the camera simply pans past it can be lower resolution opposed to having a character pick up an object, and having the camera zoom in on the object - for this you'd want a high resolution representation if not the real thing.

LIDAR scans are quite magnificent to behold. You can see the actual shapes in the LIDAR scan. You can create measurements in the LIDAR scan. You can find things in the LIDAR scene. LIDAR has been used in crime investigations to observe evidence that is not naked to the human eye. Videogames have already mimicked LIDAR's usefulness within the game itself such as in The Division - where you study a LIDAR scan from the past to find clues to investigate what happened. Lastly, LIDAR is very useful, but do not forget we can combine the data sets of LIDAR data with other types of scan data including Photogrammetry to achieve a result greater than the sum of its parts.
