Read STL File

Group (Subgroup)

IO (Input)

Description

This Filter will read a binary STL File and create a Triangle Geometry object in memory. The STL reader is very strict to the STL specification. An explanation of the STL file format can be found on Wikipedia. The structure of the file is as follows:

UINT8[80]     Header
UINT32     Number of triangles

foreach triangle
REAL32[3]     Normal vector
REAL32[3]     Vertex 1
REAL32[3]     Vertex 2
REAL32[3]     Vertex 3
UINT16     Attribute byte count
end

It is very important that the "Attribute byte Count" is correct as DREAM.3D follows the specification strictly. If you are writing an STL file be sure that the value for the "Attribute byte count" is zero (0). If you chose to encode additional data into a section after each triangle then be sure that the "Attribute byte count" is set correctly. DREAM.3D will obey the value located in the "Attribute byte count".
