| Summary | 0023377: Error in importing a rational spline IGES surface [Type 128, PROP3 = 0] into OCCT | ||||
| Description | 1. Import an IGES file with a rational spline surface [Type 128] into OCCT. 2. The input surface is rational spline defined in the homogeneous geometry section of the IGES file [The parameter with name PROP3 is defined as 0]. 3. TKIGES library while reading the IGES surface geometry checks if the input geometry is really rational or not. 4. It does this by checking non-uniform weights associated with the control points of the spline surface. 5. The library incorrectly determines that the surface geometry is non-rational and assigns the parameter PROP3 a value of 1, which makes the surface a polynomial surface. | ||||
| Steps To Reproduce | Input file [input.igs] : An IGES file with rational spline surface [Type 128, PROP3 = 0]. Output file [output.igs] : An IGES file with polynomial spline surface [Type 128, PROP3 = 1]. 1. Import input.igs into "ImportExport.exe" [An OCCT sample application for MFC]. 2. After the import process, select the imported geometry. 3. Export the selected geometry as output.igs 4. Check the exported putput.igs, it has polynomial surface [Type 128, PROP3 = 1]. | ||||
| Additional information and documentation updates | 1. The files mentioned in "Steps to Reproduce" is uploaded. 2. On investigation of the bug, it was found that the error is in IGESGeom_BSplineSurface::IsPolynomial(). | ||||
