Hello Armin, I just checked out the octomap_mapping repository (@ http://alufr-ros-pkg.googlecode.com/svn/trunk/octomap_mapping) but I cannot find the new interface you are speaking about ( insertScan(const PointCloud&pc, const pose6d originPose, double maxrange=-1, bool pruning = true) ). It does not appear in the doc generated in the build directory. If I run "less *.* | grep "insertScan" in /octomap_mapping/octomap/build/octomap-svn/src/octomap, I only see the old interfaces : void insertScan(const ScanNode& scan, double maxrange=-1., bool pruning = true); and void insertScanUniform(const ScanNode& scan, double maxrange=-1.); Here is my trace of less *.* | grep "insertScan : raph@DTI-PC030:~/rosnodes/octomap_mapping/octomap/build/octomap-svn/src/octomap$ less *.* | grep "insertScan" * the sensor model only. Do not use, e.g., insertScan. tree->insertScan(**scan_it, maxrange, false); void OcTree::insertScan(const ScanNode& scan, double maxrange, bool pruning) { this->insertScanUniform(scan, maxrange); void OcTree::insertScanUniform(const ScanNode& scan, double maxrange) { void insertScan(const ScanNode& scan, double maxrange=-1., bool pruning = true); /// Helper for insertScan (internal use) void insertScanUniform(const ScanNode& scan, double maxrange=-1.); Did I check out from the wrong repository? Sorry if it is a stupid mistake from me.
