| Standard_Boolean | Read (const char *theFile, const Message_ProgressRange &theProgress) |
| | Reads data from STL file (either binary or Ascii). This function supports reading multi-domain STL files formed by concatenation of several "plain" files. The mesh nodes are not merged between domains. Unicode paths can be given in UTF-8 encoding. Format is recognized automatically by analysis of the file header. Returns true if success, false on error or user break. More...

| |
| Standard_Boolean | IsAscii (Standard_IStream &theStream, const bool isSeekgAvailable) |
| | Guess whether the stream is an Ascii STL file, by analysis of the first bytes (~200). If the stream does not support seekg() then the parameter isSeekgAvailable should be passed as 'false', in this case the function attempts to put back the read symbols to the stream which thus must support ungetc(). Returns true if the stream seems to contain Ascii STL. More...

| |
| Standard_Boolean | ReadBinary (Standard_IStream &theStream, const Message_ProgressRange &theProgress) |
| | Reads STL data from binary stream. The stream must be opened in binary mode. Stops after reading the number of triangles recorded in the file header. Returns true if success, false on error or user break. More...
|
| |
| Standard_Boolean | ReadAscii (Standard_IStream &theStream, Standard_ReadLineBuffer &theBuffer, const std::streampos theUntilPos, const Message_ProgressRange &theProgress) |
| | Reads data from the stream assumed to contain Ascii STL data. The stream can be opened either in binary or in Ascii mode. Reading stops at the position specified by theUntilPos, or end of file is reached, or when keyword "endsolid" is found. Empty lines are not supported and will read to reading failure. If theUntilPos is non-zero, reads not more than until that position. Returns true if success, false on error or user break. More...

| virtual Standard_Integer | AddNode (const gp_XYZ &thePnt)=0 |
| | Callback function to be implemented in descendant. Should create new node with specified coordinates in the target model, and return its ID as integer. More...

| virtual void | AddTriangle (Standard_Integer theN1, Standard_Integer theN2, Standard_Integer theN3)=0 |
| | Callback function to be implemented in descendant. Should create new triangle built on specified nodes in the target model. More...

| |
| Standard_Real | MergeAngle () const |
| | Return merge tolerance; M_PI/2 by default - all nodes are merged regardless angle between triangles. More...
|
| |
| void | SetMergeAngle (Standard_Real theAngleRad) |
| | Set merge angle in radians. Specify something like M_PI/4 (45 degrees) to avoid merge nodes between triangles at sharp corners. More...
|
| |
| double | MergeTolerance () const |
| | Return linear merge tolerance; 0.0 by default (only 3D points with exactly matching coordinates are merged). More...
|

| void | SetMergeTolerance (double theTolerance) |
| | Set linear merge tolerance. More...

An abstract class implementing procedure to read STL file.
This class is not bound to particular data structure and can be used to read the file directly into arbitrary data model. To use it, create descendant class and implement methods addNode() and addTriangle().
Call method Read() to read the file. In the process of reading, the tool will call methods addNode() and addTriangle() to fill the mesh data structure.
The nodes with equal coordinates are merged automatically on the fly.
