Representation of 3D Motion by Projective Angles
Volume 5C: 39th Mechanisms and Robotics Conference, 2015Angular motion in 3D space has been represented using several approaches, such as cardanic angles, quaternions, Euler parameters. Notwithstanding that in some applications some of them are more convenient, none of these solutions is completely satisfactory as a general tool. After a critical review of the main advantages and drawbacks of each notation,

Segmentation of muscles for 3D representation of acupoints
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Based on the dataset of the male Visible Human and the VOXEL-MAN software, original work for 3D representation of acupoints and acupuncture treatment has been reported. To get a realistic model, segmentation is one of the most important procedures in the whole process.

Representation of hierarchical structures in 3D space
Proceedings of the 1st international conference on Computer graphics, virtual reality and visualisation, 2001Hierarchical structures are found in much of the data that is used in everyday life including organisational management hierarchies and computer directory structures. The effective visualisation of large hierarchical information structures on limited size and resolution computer displays is important.

Medial Axis for 3D Shape Representation
2011Cortical representation of shape is a crucial problem in vision science. Recent physiological studies on monkeys have reported that neurons in the primary visual cortex (V1) represent 2D shape by Medial Axis (MA). Physiology has also shown that a set of smooth surfaces represents 3D shape in a higher stage (IT).

A compact representation for scanned 3D objects
2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009We consider the representation of densely sampled scanned 3D objects. Scanning physical objects can be an efficient way of obtaining natural looking input for computer graphics image generation. Scanned meshes however require large amounts of storage.

Sensor Representation in 3D Virtual Environments
Proceedings of the 2015 International Conference on Big Data Applications and Services, 2015Various types of physical sensors are currently being used in the real world, and it is expected that the number of sensors and their types will increase with advancements in physical sensor technologies. Physical sensors integrate with 3D virtual worlds by way of information convergence technologies, including mixed and augmented reality.

Sparse representation of deformable 3D organs
2009 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2009Parametric representation of deformable object with complex surface has been a challenge in various medical applications for its demanding resource consumptions. This paper proposed an efficient algorithm to construct a compact basis for a sequence of deformed 3D organ, in which those surfaces can be sparsely represented with a small number of ...

Representation of 3D Rotations
1990In this chapter, we study various aspects of 3D rotations. We first prove Euler’s theorem and show how to parametrize a 3D rotation and how to compute compositions and inverses. For this purpose, we present many different representations of 3D rotations—by a rotation matrix, an angle and an axis, the Euler angles, the Cayley—Klein parameters, and a ...

The most primitive data representation unit in a three-dimensional Euclidean space is the 3D point itself, p i . This chapter gives a basic overview on acquisition techniques for 3D points, as well as on representation formats for collections of points in the context of mapping with mobile robots.
