Abstract
The 3DOR workshop series provides a unique venue for researchers, students, and practitioners interested in the definition, evaluation, and application of 3D object analysis and retrieval. Eight papers were selected for oral presentation, giving an acceptance rate of 50%. This year, like last year, 3DOR'11 hosts the Shape Retrieval Evaluation Contest (SHREC'11) which plays an important role in the evolution of 3D Object Retrieval research. SHREC'11 contributes to the proceedings with four additional papers that detail the results of the competition. The proceedings furthermore comprise six papers providing timely research results of high quality which were included in the workshop program in form of poster presentations.
