Line
- mert.goktas (Unlicensed)
In OpenBrIM, 3D representations can be defined using the following objects:
Surface
Volume
Line
Each Line object must include:
A first Point object
A second Point object
At least one Section/Shape/Surface object
Given two points and a cross section, OpenBrIM can render the line with the specified section profile. For polylines, multiple points can be specified, and a Line object can contain multiple Section objects if multiple points are defined in the line.
To create a line, two "point" objects are required that define the start and end of the line. These points are combined using the "line" object to express the line.
