Re: [osg-users] [vpb] Some questions about VPB and cloud of points

Hi Glenn, thank you for your answer. What do you think about the first question? Can i create a dem file starting from a cloud of points using osgdem? This cloud of points is an ascii file with n rows each one with x,y,z values. These values are referred to a coordinate system (i know this one).

Re: [osg-users] view-dependent Billboard clouds

Hi Basheer, A scenegraph solution is possible by using a nodemask. This way different views can traverse into different parts of the scenegraph containing the nodes you want to use for a specific view. However in this case the scenegraph is specifically tailored for the number of views you are

Re: [osg-users] [vpb] Some questions about VPB and cloud of points

Andrea, I'm afraid I don't know the answer to that one. All the OSG terrain options take a regular grid of height postings as input, so you would probably need to preprocess an arbitrary could if you want to go that route. osgdem, osgEarth, etc. all use GDAL under the hood to read data formats;

[osg-users] Paging strategies for road tiles

Hi all, My application involves road vehicles driving down long roads. Approx 1000 km of continuous road. The problem is that I can only hold about 100 km of road before system memory runs out. Plan B then naturally falls on some sort of paging strategy. I rewrote the software so it generates

Hi Bjorn, It looks like the problem is your tiles are larger than 2000 m radius. Try setting the range to the tile radius, or some multiple (1.5 * radius, 2.0 * radius). Brian This is a PRIVATE message. If you are not the intended recipient, please delete without copying and kindly advise us

[osg-users] osg, Qt and python

It seems that following Qt going LGPL we will soon have LGPL python bindings (the current pyqt is commercial). Has anyone any experience/interest in a python QtViewer? Both the pyqt and the new pyside bindings are very thin wrappers around the Qt C++ code so it shoudn't be a huge challenge.
