What is 3D surface rendering?
3D-DOCTOR’s, 3D surface rendering commands create 3D surface models from object boundary lines or contours. The 3D surface model consists of triangle faces. Multiple objects can be combined together using 3D surface rendering. There are 2 surface rendering commands in 3D-DOCTOR: Simple Surface Rendering and Complex Surface Rendering. They both create 3D surface model but use different algorithms and are suitable for different objects. The simple surface rendering uses a proprietary algorithm to create smooth and simpler surface models. This method is fast and the models are better suited for rapid prototyping and volume calculation applications. The complex surface rendering uses a triangulation algorithm. This method is slow but robust, and is better for rendering objects with complicated branches and topologies. With 3D-DOCTOR, you can select the proper rendering method for an object and mix multiple objects created using different rendering methods for 3D display.
