Question: Who created a 3d model of Tom Hardy's face?
About the article "The Dark Knight Rises", section "Costume design".

Candidate passages:
Scientists at Imperial College London created a detailed 3D computer model of the arachnid from fossils. 
Costume design.
Costume designer Lindy Hemming explained that Bane uses a mask to inhale an analgesic gas, which, in director Christopher Nolan's words, "keeps his pain just below the threshold so he can function."
In designing Bane's costume, Hemming needed it to look "like an amalgam of all sorts of bits and pieces he cobbled together, as he passed through some very remote places.
We made parts of his vest, for example, from fragments of an old military tent.
His clothes are militaristic, but are not in any way a uniform."
Hemming also designed Bane's mask to look "animalistic".
Costume effects supervisor Graham Churchyard created a three-dimensional model of actor Tom Hardy's face and skull to design the mask, allowing the mask to perfectly conform to the contours of Hardy's face.
Hemming personally designed Bane's coat, which she admitted took two years to complete.
Taking inspiration from a Swedish army jacket and a frock coat from the French Revolution, it was designed to make Bane look like equal parts dictatorial and revolutionary.
The design was difficult as Hemming struggled to find a tailor in Los Angeles who could work with shearling.
The Batsuit consisted of 110 separate pieces, each of which had to be replicated dozens of times over the course of the production.
The base layer was made of a polyester mesh that is utilized by the military and high-tech sports manufacturers because of its breathability and moisture-wicking properties.
Molded pieces of flexible urethane were then attached to the mesh, to form the overall body armor plating.
Carbon fiber panels were placed inside the sections on the legs, chest and abdomen.
The cowl was sculpted from a cast of Bale's face and head to become a perfect fit for Christian Bale.
The suit remained unchanged for the film since "The Dark Knight".
In creating Selina Kyle's catsuit, two layers of material were used, with the outer layer being polyurethane coated spandex, embossed with a hexagonal pattern.
The catsuit also consisted of elbow-length gloves, a utility belt, and thigh-high boots with spike heels.
A digital elevation model is a digital model or 3D representation of a terrain's surface — commonly for a planet (including Earth), moon, or asteroid — created from terrain elevation data. 
Three-dimensional face recognition (3D face recognition) is a modality of facial recognition methods in which the three-dimensional geometry of the human face is used.
It has been shown that 3D face recognition methods can achieve significantly higher accuracy than their 2D counterparts, rivaling fingerprint recognition.3D face recognition has the potential to achieve better accuracy than its 2D counterpart by measuring geometry of rigid features on the face.
This avoids such pitfalls of 2D face recognition algorithms as change in lighting, different facial expressions, make-up and head orientation.
Another approach is to use the 3D model to improve accuracy of traditional image based recognition by transforming the head into a known view.
Additionally, most range scanners acquire both a 3D mesh and the corresponding texture.
This allows combining the output of pure 3D matchers with the more traditional 2D face recognition algorithms, thus yielding better performance (as shown in FRVT 2006).
The main technological limitation of 3D face recognition methods is the acquisition of 3D image, which usually requires a range camera.
Alternatively, multiple images from different angles from a common camera (e.g.
webcam) may be used to create the 3D model with significant post-processing.
This is also a reason why 3D face recognition methods have emerged significantly later (in the late 1980s) than 2D methods.
Recently commercial solutions have implemented depth perception by projecting a grid onto the face and integrating video capture of it into a high resolution 3D model.
This allows for good recognition accuracy with low cost off-the-shelf components.3D face recognition is still an active research field, though several vendors offer commercial solutions. 
UV mapping is the 3D modeling process of making a 2D image representation of a 3D model.
