3D model may be manipulated so that its shape could be observed from any view, and is displayed on the screen by static state and dynamic. The property of volume and the moment of inertia matrix are obtained from the octree of object by the algorithms presented in this dissertation. To fit the application of recognition, we studies the method by which 3D model octree is used for recognition.

Inscribed polygons are used to approximate a circle, and the number of line segments compose the polygon is detemined by the radius and its image of a circle. Calculation of rotation angles between circle and world coordinate systems with normal vector of circles is also discussed. The proposed approach is tested with several real image data, and results are very satisfying.

Diplopia and disturbance of ocular movement are related to the incarceration of the extraocular muscles and the displacement of orbital wall, and the management is simple relatively. However, the treatment of enophthalmos is difficult because the orbital reconstruction is made to be complicated by the complex morphous of orbital wall and the limited operative area. This study introduced the use of CAD/CAM technique in orbital reconstruction, and the result is more satisfactory than traditional methods.

眶壁重建是其矫治的首要条件，然而，眶壁形态复杂，并有视神经由眶尖通过，加之术野受限，使精确的解剖复位很难完成，本文应用CAD/CAM技术，术前成型钛网并行眶壁重建，通过CT分析和眼科检查，证实该技术在眶壁重建的精确性上均较传统方法有明显提高，其中，眶内壁的修复程度和眶底修复形态的对称性，以及眶容积缩小程度反映了其形态修复的精确性，而置入深度则体现了在缺损修复范围设计中的优越性。

Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.
