I've noticed that if you remove all the lines containing the keyword "color" the file is correctly displayed. I guess it should be enough to skip those lines when reading the ascii STL file to resolve the bug. I.e. -----------------8<------------------------------- solid bw-a-pillar-bottom-LEFT color 0.98824 0.13333 0.49804 facet normal 0.065777868 -0.994380057 0.0829555467 outer loop vertex -1236.36243 709.844604 755.906372 vertex -1235.98022 708.72937 742.235107 vertex -1243.3512 708.230164 742.095825 endloop endfacet facet normal 0.0584581681 -0.994519949 0.086676009 outer loop vertex -1236.36243 709.844604 755.906372 vertex -1243.3512 708.230164 742.095825 vertex -1244.53064 709.432861 756.69104 endloop endfacet [...] -----------------8<------------------------------- becomes: -----------------8<------------------------------- solid bw-a-pillar-bottom-LEFT facet normal 0.065777868 -0.994380057 0.0829555467 outer loop vertex -1236.36243 709.844604 755.906372 vertex -1235.98022 708.72937 742.235107 vertex -1243.3512 708.230164 742.095825 endloop endfacet facet normal 0.0584581681 -0.994519949 0.086676009 outer loop vertex -1236.36243 709.844604 755.906372 vertex -1243.3512 708.230164 742.095825 vertex -1244.53064 709.432861 756.69104 endloop endfacet [...] -----------------8<------------------------------- Hope this helps some developer to write a quick fix to this issue. |

I've written a quick fix to this problem. Here it is the result from the diff command against the official 3.4.0 release: -----------------8<------------------------------- [ParaView-3.4.0]$ diff VTK/IO/vtkSTLReader.cxx ../ParaView-3.4.0-release/VTK/IO/ 313,316d312 < if ((strcmp(line, "COLOR") == 0) || (strcmp(line, "color") == 0)) < { < done = (fscanf(fp,"%s %*s %f %f %f\n", line, x, x+1, x+2)==EOF); < } 361,365d356 < if ((strstr(line, "COLOR") == 0) || (strstr(line, "color") == 0)) < { < done = (fscanf(fp,"%f %f %f\n", x,x+1,x+2)==EOF); < done = (fscanf(fp,"%s", line)==EOF); < } -----------------8<------------------------------- Basically, the only routine changed is vtkSTLReader::ReadASCIISTL, adding the check on a possible "color" line just after every time the parsing of a solid block starts. The proposed modification can read STL ascii files with and without the "color" line. The modified file is attached. I hope this helps and the fix, or a better version, could be eventually included in the next release. Francesco |

Looks fixed to me. Tested local client, XP. |
