Computer-based, three-dimensional reconstruction of histological sections is necessary for solving a diversity of questions in morphology and anatomy. Programming software for this purpose is difficult and time-consuming. Therefore, we tested if commercially available product-design software is useful for reconstructing anatomical virtual models.
We used Alias Wavefront Studio software on a Silicon Graphics workstation. Sections were projected with a newly developed microslide projector on a digitizing board and digitized interactively. Alternatively, pictures of sections were digitized on screen. The resulting set of contours was used as scaffold around which a surface was created manually.
Repeated creation of the same object and subsequent measurements gave results that will be sufficiently reliable for many purposes. The visual presentation of objects satisfy highest demands. Little time is needed to reconstruct simple objects, and the time used for complex virtual models is acceptable. Manipulation of objects on screen is nearly in real time and rendering speed is high.
Product-design software packages are a readily available and useful option for anatomists who want to do virtual reconstructions quickly without programming software themselves.
基于计算机的组织学切片三维重建对于解决形态学和解剖学中的各种问题是必要的。为此目的编写软件既困难又耗时。因此，我们测试了市售的产品设计软件是否有助于重建解剖虚拟模型。
我们在硅图形工作站上使用Alias Wavefront Studio软件。切片通过新开发的显微切片投影仪投射到数字化板上并进行交互式数字化。或者，切片的图片在屏幕上数字化。得到的轮廓集用作围绕其手动创建表面的支架。
重复创建相同对象并进行后续测量所得到的结果对于许多目的而言将足够可靠。对象的视觉呈现满足最高要求。重建简单对象所需时间很少，用于复杂虚拟模型的时间也可以接受。在屏幕上对对象的操作几乎是实时的，渲染速度很高。
对于那些希望在不自行编写软件的情况下快速进行虚拟重建的解剖学家来说，产品设计软件包是一种现成且有用的选择。
