My name is Carlos Buchart, and I'm a software engineer at STT (Spain), and Associated Professor at TECNUN (Spain). My work is mainly focused on computer graphics and my research work includes surface reconstruction, medical data visualization, computer assisted modeling and scientific visualization in general. I'm also interested in algorithm performance, memory management, filesystems, user interfaces design, cryptography and graphic design. I got a Computer Science MS in 2005 (University of Carabobo, Venezuela) and received my PhD in 2010 (University of Navarra, Spain).

In my 'normal' life I enjoy writing songs, singing (as soloist and as bass in a choir), playing guitar, developing iOS applications, reading books about the Ancient World and scientific divulgation, talking about the weather when a conversation is taking difficult, videogames and cooking. I'm also a big fan of StarWars, Harry Potter, Apple, the Godfather, the Big Bang Theory, Rurouni Kenshin and Dragon Ball. You can find more about some of these topics in my blog (in Spanish).

    • Projects

    At CEIT I focused on the development of simulators, medical imaging software, training systems and computer graphics horizontal support to other projects and units.

    In my spare time I enjoy developing small applications. Most of them are not published yet, but I've started to make public versions of them. Please, keep in touch for new releases [RSS].

    Past relevant projects

  • Information and visualization tools for the efficient interaction of the documentation associated to machine-tools. CEIT, Spain. 2012-2013.
  • Portable digital X-ray detector. My main role in this project is in the development of the image processing module of the detector. CEIT, Spain. 2012.
  • mtReconstructionLib. A surface reconstruction library from unorganized points. This a result of my PhD Thesis, and several modules have been used in other projects such as MaxiPlan. [Temporal link].
  • Volumetric visualization related projects. Horizontal support to several medical visualization projects of the Simulation Unit of CEIT. [Temporal link].
  • MaxiPlan: a planning and simulation software for maxillofacial surgery. My participation in this project included: user interface, planning, volumetric visualization and surface reconstruction. CEIT, Spain. 2005-2008.

    • viewitLib

    viewitLib is a framework developed by CEIT for building medical applications that have a strong visualization workflow. It includes support for several visualization widgets such as 2D/3D slices and volumetric visualization, it provides a set of commonly used interaction tools and it is easily customizable. It has been used for quickly building of several applications, such as the ones listed in this section.

  • viewit-Cranium: a multimodal neurosurgery simulator.
  • viewit-Kinect: a proof-of-concept tool for medical image visualization that uses the Kinect for the navigation.
  • viewit-IsoExtract: a simple tool for visualization and extraction of iso-surfaces from medical images.
  • viewit-Tractography: a visualization tool for diffusion tensor imaging.


    • viewit-Spine: a planning and simulation tool for spine surgeries, specifically for those where it is necessary to place screws in a damaged vertebra. The software builds a digital model of the damaged spine, while simultaneously indicates to surgeons which implants are needed and where to place them, along with information about the orientation and size of the implants. [Video].

    Personal projects


    WallCamera LockScreen: this utility helps you to take pictures that are going to be used as wallpapers in your iPhone / iPod Touch. It gives you a live preview of how your lock screen will look like, so you can take a great picture. The camera interface mimics the lock screen so you can use it as a guide.


    Quickial: is an app for quickly search your contacts. It reduces the number of keys and replaces them with a very smart engine for searching your contacts. You can also define the default phone number to dial, and its alternatives.
