      Este artigo descreve os recentes desenvolvimentos num trabalho ainda em curso referente a uma nova abordagem à craniometria tradicional baseada na análise de modelos digitais 3D de crânios através da aplicação CraMs ...

    • MedUse: A Visual Analysis Tool for Medication Use Data in the ABCD Study 

      Bartsch, Hauke; Garrison, Laura; Bruckner, Stefan; Wang, Ariel; Tapert, Susan F.; Grüner, Renate (The Eurographics Association, 2019)
      The RxNorm vocabulary is a yearly-published biomedical resource providing normalized names for medications. It is used to capture medication use in the Adolescent Brain Cognitive Development (ABCD) study, an active and ...

    • Megakernels Considered Harmful: Wavefront Path Tracing on GPUs 

      Laine, Samuli; Karras, Tero; Aila, Timo (ACM, 2013)
      When programming for GPUs, simply porting a large CPU program into an equally large GPU kernel is generally not a good approach. Due to SIMT execution model on GPUs, divergence in control flow carries substantial performance ...

    • MegaViews: Scalable Many‐View Rendering With Concurrent Scene‐View Hierarchy Traversal 

      Kol, Timothy R.; Bauszat, Pablo; Lee, Sungkil; Eisemann, Elmar (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present a scalable solution to render complex scenes from a large amount of viewpoints. While previous approaches rely either on a scene or a view hierarchy to process multiple elements together, we make full use of ...
