3D Scanning Sculpture – Contemporary Sculptor and Original Works of Art
3D Interactive Virtual Reality Example: Click the above image to control in ‘Virtual Reality 3D’. Your touch-screen controls are: Rotate: single finger, Zoom IN & OUT: two finger spread, Move UP/Down: two finger slide.
Please Note! The above interactive model is heavily compressed to allow it to move online in realtime. Hence a lot of the 3D scan detail which we have origionally captured can’t been seen. See the below images of our actual 3D scan to see the difference.
3D Scanning Sculpture – Professional 3D scans of sculpture
The above virtual reality model was generated from a 3D scan we recently carried out of a fabulous nude study by the wonderful Bushra Fakhoury. As always, Bushra’s distinct style evokes movement, energy and intrigue!
Although the above 3D scan looks pretty reasonable, it has been heavily compressed to enable smooth online control in realtime (this is typical with any online virtual reality App). Hence much of the fine detail which we captured in our original 3D scan, is not visible in the VR version. If you compare the above VR version with the below actual scan screen captures, you will notice a big difference in scan resolution and detail.
This is important to mention because the 3D physical replicas we produce from 3D scans, do actually capture a high level of detail (up to 0.5mm accuracy). Such high detail can then be transferred to physical output devices such as 3D printers and CNC milling machines. This means we are able to produce virtually identical physical replicas from 3D scans, which can be used for high quality bronze castings, resin moulds or whatever!
How 3D scanning sculpture helps Sculptors and Conservators
Superscan 3D specialise in 3D scanning sculpture for an extensive list of leading contemporary Artists and Sculptors who have come to understand the commercial benefits of this amazing technology.
We are able to 3D scan many different types of materials such as: stone, wood, clay, metal, foam, plastic, glass and even porcelain. We use the very latest aerospace none contact scanning technology to achieve amazing 3D scans, which can be accurate up to 0.5mm. Such accuracy usually enables us to capture an Artists touch and expression.
We are typically able to 3D scan objects upwards of 30cm. Once scanned, objects can be digitally re-scaled to the desired physical output scale. We can then either use CNC milling to produce larger physical mould masters, or 3D printing to produce smaller physical mould masters.
Finally, the output mould masters are carefully hand finished ready for the final bronze casting stage, or whatever output medium the client requires. Hence, 3D scanning sculpture is a real game changer for Artists and Sculptors, as it enables high detail limited edition copies to be produced at virtually any scale!
Post Scan Digital Cleanup – How does it work?
Once an object has been carefully 3D scanned, the 3D scan data needs to then go through a post-scan cleanup process before it can be used for 3D printing or CNC milling. This is what we refer to as ‘Post Scan Digital Cleanup’. We import the RAW 3D scan data into various 3D modelling applications, in order to remove any anomalies or errors in the RAW 3D scan data, and iron out any slight imperfections in the 3D polygon mesh.
Consider that 3D scanners capture surface information, and are ‘Line of Sight Technology Devices’. This means they digitally acquire physical objects using optical capture, for which there are various technologies available (White Light, Photogrammetry, Lidar/Laser and variants).
Of course, light travels in a straight line, hence certain physical objects can prove difficult to scan where line of sight is restricted (cavities, holes, restricted areas). In these situations it is usually necessary to carry out alterations to the digital 3D mesh, using specialist post scan 3D software.
Occasionally, a 3D scanner may not be able to capture every precise detail due to varying surface characteristics. Common surface challenges tend to be shiny or highly polished surfaces, satin surfaces, dark or black surfaces, powdery or flakey surfaces, as well as wet or slightly damp surfaces.
The various images on this page show various screen captures of us cleaning up the above 3D scan using Z-Brush software. Think of Z-Brush as an application that enables us to digitally sculpt the 3D scan data, which is actually a high density polygon mesh. Z-Brush refer to this process as ‘digital clay’. Hence we are able to make certain surface repairs in preparation for 3D printing, CNC milling or whatever output application is required. Remember, this is digital data! If you don’t fix the RAW 3D scan data, your 3D printer or CNC device will simply reproduce the file it receives, errors included!
This incredible technology also allows us to 3D scan certain sculptures in 24-bit colour. This then enables us to generate a precise 3D digital-double, which can be used for online interactive, conservation research, TV documentaries and many other digital applications.
3D scanning also enables us to ‘Up’ or ‘Down’ scale original sculptures. Hence, some well known Artists are now using our services to accurately reproduce previous works for public exhibitions and private commissions.
