Re: [osg-users] [osgPlugins] Does FBX (or any other) plugin supports ForceReadingImage ?

Hi Felix, The OSG is written so that it osg::Image are assumed to be valid and can be applied to textures, so if the OSG isn't able to load a particular file it returns NULL, or if you wish to capture the ReaderWriter::ReadResult you'll get a FILE_NOT_FOUND. If you want to modify this behaviour

Re: [osg-users] [build] Simple example link errors with cygwin

HI Micael, I don't use cygwin, and few others do, so I'm afraid you'll be largely on your own. If you need guidance then I'd suggest starting with the OSG examples - do these compile, then have a look at the make options that cmake builds for them. running: make VERBOSE=1 Is the way to get

Re: [osg-users] Memory allocation problem with big models

Hi Ale, My guess is that it's OpenGL side that is consume all the memory, but as you haven't provide any stack trace it's impossible for say this definitively. Breaking an object into smaller parts won't help if it's OpenGL objects that are consuming all the memory, it will likely help with

Hi Robert, thank you for your reply. I appreciate your help :) I'm sorry if I didn't express myself correctly. I also have to admit I'm not quite the expert on computer graphics. Let's try to make it clearer. I want to know which of the lines on my model are visible in a rendered image. That

Re: [osg-users] RigTransformHardware skinning on DAE models

Hi default implementation uses vertex attribs from slot 11 upwards for bone weights, and most implementations have GL_MAX_VERTEX_ATTRIBS = 16, so with more than 4 attributes you are probably hitting hardware limits on vertex attributes count, i think gl error comes from this too. Cheers.

Re: [osg-users] Rendering sets of objects in layers/passes

Hi using separate renderbin ID for each set of objects should do exactly what you want, as they should be sorted by depth inside each set, and sets rendered in order of renderbin ID's. How you assigning render bin ids? You may need to set RenderBinMode to USE_RENDERBIN_DETAILS or

[osg-users] Texture compilation using PixelBufferObject

Hi, Let's imagine this scenario: The database pager loads the file x.osgb. This file contains 3 geometries (A, B, C). A has a texture that uses A.jpg, B uses B.jpg and C uses C.jpg. These textures are not used by the already rendered geometry (i.e. not compiled) The

Re: [osg-users] osgearth terrain problem

I'm not very familiar with osgearth terrains but I'm pretty sure the quad tree is made up of something like osg::PagedLOD nodes, each with a TerrainTile and a group of similar child osg::PagedLOD nodes. As each osg::PagedLOD is loaded, the range is evaulated to decide whether to load the next
