3D Mesh Model Generation from CT and MRI data

In order to render 3D virtual environment more realistically, one often needs to generate cylindrical image model real-timely. In this article, schemes to accelerate the process are proposed, in which two aspects of efforts, visibility detection and multi-resolution technique, are involved. Experimental results are also included to validate the algorithm, which exhibits that using visibility detection in conjunction with multi-resolution technique can significantly reduce the amount of computation and hence accelerate the generation process.

Geometric Simulation

The purpose of this paper is to geometrically simulate warp-knitted medical tubular bandages with a computer-aided simulator. A flat mesh model is established according to unfolded fabric considering the knitting characteristics of double-needle bed warp-knitted tubular fabrics. Moreover, a 3D (three-dimensional) mesh model corresponding to the actual product shape is created. To better describe the spatial geometry of stitches, eight-point models are introduced, and stitches are generated with the flat mesh model. Founded on matrix operations, the stitch position in the 3D mesh model is determined through coordinate mapping. Various stitch paths are rendered in computer programming languages C# and JavaScript to conduct simulations. Warp-knitted medical tubular bandages with a large number of shapes are effectively modeled.
