Surface Rendering of Arbitrary Section Planes Based on Brain Volume Data of Virtual Chinese Human(Male No.1);

Visualization evaluation of surface rendering and volume rendering by three-dimensional echocardiographic intracardiac endoscopic simulation system

Volume rendering is a newly-developed visualization algorithm which differentiates from the classical surface rendering.

3D fusion image can be reconstructed by way of surface rendering, which applies a searching algorithm of volume data.

Though developed later than surface rendering and having a wider adaptability to object data sets, the algorithm of volume rendering still can not be put into use in practical medical imaging application,simply because it could not meet the speed requirement for interactive operation due to the large amount of computation involved.

The visualization technique of medical images includes two parts:volume rendering and surface rendering.

By summarizing the experiences of survey of tunnel s section and using ObjectARX and its plug-in technology,we developed and accomplished general tunnel s section plotting software which had stronger expansibilty and more flexible applicability.

The article introduces mainly the steps,essentials and techniques of section_drafting by the software Pro/Engineer,aimed at indicating the method of exact and quick section_drafting,which makes the excellent and strong functions of the software Pro/Engineer receive wide application.
