Render pointcloud from STL mesh file

STL vs SDF

STL (STereoLithography) and SDF (Spatial Data Format) files are two different file formats used for different purposes in 3D printing and computer-aided design (CAD).

STL files are primarily used for representing the surface geometry of 3D objects. They are made up of a collection of triangular surfaces (also known as facets) that approximate the shape of the object. The file format was originally developed for use with stereolithography machines, but it has since become a standard file format for 3D printing and rapid prototyping. STL files are simple, lightweight, and widely supported by 3D printing software.

On the other hand, SDF files are a more comprehensive format that includes not only the surface geometry of the 3D object, but also additional information such as color, texture, material properties, and lighting. SDF files are often used in 3D modeling and animation software to represent complex 3D scenes that need to be rendered with high accuracy and realism.

In summary, STL files are mainly used for surface representation of 3D objects, while SDF files are more comprehensive and include additional information beyond surface geometry.
