The computer graphics field of sketch-based interfaces and modeling (SBIM) is concerned with algorithms and mathematical models inspired by the traditional use of sketches (1) to establish the geometry and topology of the subject being depicted; and (2) to conceptualize ideas and to interpret data. In SBIM, our group has focused on three main research directions. (1) Building the overall geometry and topology of 3D models. (2) Augmenting existing 3D models with geometric details. (3) Using sketches as operators, indicators, and for annotation.

Highlights of our research in SBIM include algorithms and methods applied to the disciplines of geoscience, botany, and medicine, in collaboration with domain experts from industry and academia. Papers reporting our results were among the first publications introducing and applying SBIM to these three disciplines. We also published one of the first surveys of SBIM techniques (Olsen et al. '09)

To date, SBIM projects in our group are organized into seven categories:

  1. Sketch-based 3D geological modeling (Costa Sousa et al. '15, Jackson et al. '15) enabling users to perform two tasks: (1.1) interactive rule-based modeling of geological structures inspired by traditional geological map view sketches and conventional symbols and annotations (Amorim R et al. '14) and cross-sectional view sketches (Rood et al. '15); and (1.2) interactively adjust the geometry and extract features of interest by sketching directly over geoscience data including (a) seismic volumes (Amorim R et al. '12 (a, c)), (b) micro-seismic point-clouds (Amorim R et al. '12b), and (c) outcrop analogues (Sultanum et al. '13). All the research in this Category 1 is in collaboration with researchers and professionals (from both industry and academia) in geoscience and petroleum engineering. Papers reporting our results were among the first publications - i.e., in both comaputer science and reservoir geoscience & engineering journals and conferences - introducing and applying SBIM to geoscience problems. Our group is also coordinating and co-investigating the international joint industry project (JIP) "Rapid Reservoir Modeling (RRM)" where SBIM technologies play a central role;

  2. Hybrid sketch-based and procedural modeling of plants, enabling users to interactively model plant structures inspired by traditional concept botanical sketches (Anastacio et al. ['06, '08, '09], Streit et al. '06). In this research, rule-based construction lines from the input sketches are employed as a way to define and manipulate global-to-local characteristics of L-system models. This work was in collaboration with botanical illustrators and researchers in the discipline of botany. Papers reporting our results were among the first publications applying concept-driven SBIM for botanical modeling;

  3. SBIM manipulation of 3D medical data to rapidly extract features of interest from volumetric data -- i.e., Chen et al. '06 (also, '08 from RT-4: M&S), de Araújo et al. '04 --, in collaboration with medical researchers and clinicians. Papers reporting our results were among the first publications applying SBIM for medical data manipulation. The work from Chen et al. '08 also resulted in a patent US20090322748 and technology transfer to industry;

  4. Fundamental SBIM research for different geometric and topological representations, including adaptive meshes (Olsen et al. '05, Paiva et al. '11 ), parametric surfaces (Cherlin et al. '05, Severn et al. '11), and implicit surfaces (Costa Sousa '07a, Vital Brazil et al. ['10b, '14, '15], Schmidt et al. ['05(a, b), '07], Wyvill et al. '05 );

  5. Gesture recognition for sketch-based interfaces (Olsen et al. '07, Severn et al. ['06, '11]);
  6. Sketch-based warping of multi-channel images for image-based editing and visual effects (Pereira et al. '11).
  7. Integrating mixed reality with sketch-based interfaces (Xin et al. ['07, '08], from RT-5: HDCI);
