ReadStl

Read module for Sandia Stl data.

ReadStl converts the representation of a surface in Sandia Stl format (specified as file browser parameter) to a format acceptable for Covise (on the first output port, e.g. used as input for the Renderer); in addition, it supplies normals on the second output port.

Please note: ReadStl can read ASCI files and binary files . In most cases (less than 1 Million cells), ReadStl will detect the filetype automatically (parameter Format = autodetect), if not, use manual selection. The module supports binary input since Release 5.2.3

Parameters

Name	Type	Description
file_path	Browser	input file describing the surface in Sandia Stl format
Format	Choice	file format: Autodetect = automatic selection ASCII, Intel, Unix = manual selection
color	String	Give this color to the geometry to be read. Enter either a textual representation like red, green, yellow or rgb values seperated by blanks (like: 255 0 255).
RemoveDoubleVertices	Boolean	Check if multiple verticess should be removed from the resulting triangulation.
ShowFeatureLines	Boolean	Check if feature-lines should be calculated.
FeatureAngle	Slider	Angle used for the recognition of sharp edges.
FlipNormals	Boolean	Check if the resulting triangulation should have inverted normals. Use if you see wrong lighting of your geometry.

Output Ports

Name	Type	Description
outputsurface	Polygons	Grid (surface in Covise format)
outputnormals	Unstructured_V3D_Normals	normals
outputfeature_lines	Lines	Output of lines.

Examples

The map above shows you how to connect the output ports of ReadStl without using normals (Renderer 1) and with using normals (Renderer 2).

The output shows Renderer 2:
