Read_Triangle

Synopsis

reads in triangle-oriented CAD/CAM geometry formats such as RAW, STL, SLP, and TIN

Input Port

ui_parent

user interface parent object

Parameters

Read Filename

UIfileSB

pick file to input

Output Port

field

Mesh + Cell_Data

Description

Read_Triangle reads in files in RAW, STL, SLP or TIN format and out puts the data in a mesh.

RAW triangle files contain a sequence of triangles, each specified by a single line of text which contains the x,y,z coordinates for each of the three verticies of the triangle.

-3.52 -4.19 -5.08 -3.91 -6.21 -5.08 -3.4 -6.21 -7.01

Optionally, the lines may be preceeded by a RGB color specification,

with each color in the range 0.0 to 1.0

1.0 0.0 0.0 -3.52 -4.19 -5.08 -3.91 -6.21 -5.08 -3.4 -6.21 -7.01

A TIN file represents a Triangulated Irregular Network File. The term "TIN" gets applied to several diferent formats - this reader accepts simple format that is similar to RAW format.

Note that the TIN reader at the IAC handles a different format.

t -3.52 -4.19 -5.08 -3.91 -6.21 -5.08 -3.4 -6.21 -7.01

STL (Stereo Lithography File) and SLP (Pro/Engineer Render File) are very similar formats. Read_Triangle only reads ASCII STL files. Usually these file contain triangles, but the format allows any number of verticies per facet. This reader handles quads by simple on-the-fly triangulation.

Input

ui_parent

A port to connect to a user interface object that contains the macro's widgets. By default, it is connected to the default user interface object in the application in which the macro is instanced. (This default connection is not drawn.).

Parameters

Read Filename

File browser. Selects the disk file to input and convert.

Output Port

field

The output is an unstructured mesh containing triangle cell sets. If color information is in the file, cell data will be added to the mesh.

out_obj

A renderable version of the output field.

Example
