Hi, ok that was a good idea. I double-checked, and yes my runtime libs were from the VS8 SP1. The weird thing is, now I can not get it to fail again?! It was late, maybe I dreamed it? :-S thanks for the suggestion -- mew On 9/14/07, Serge Lages <[EMAIL PROTECTED]> wrote: > > On 9/14/07, Mik

Re: [osg-users] Sharing statesets across files

Looks like you may also want to call this: osgDB::Registry::instance()->getOrCreateSharedStateManager()->setShareMode(S HARE_TEXTURES | SHARE_STATESETS); since SHARE_TEXTURES is the default. _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Franklin Sent: Sunday,

Re: [osg-users] Sharing statesets across files

Hi Matt, SharedStateManager is what you want. I didn't have luck improving performance with it, but you can check it out. I believe the DatabasePager shares the states when data is paged in if the SharedStateManager exists. (I don't think it is initialized by default). You have to call: osg

Re: [osg-users] Sharing statesets across files

OSG's OpenFlight loader supports this. A "parent" flt file contains texture and material palettes, which, when loaded into OSG, become arrays of StateSets with texture and material values. If the parent model then uses external reference records, and specifies that the parent palettes override chil

[osg-users] Addition and Subtraction

Hello, there. I have searched tutorials and the reference guide, but I couldn't find anything on addition and subtraction of shapes, if there is such a thing. My problem is to render a shape missing its intersection with another one. In another words: a box with a hole. How do I do this? Thanks,

Re: [osg-users] Sharing statesets across files

Hi Matt, I'm afraid there isn't a mechanism for sharing objects between separate .osg or .ive files, only between one file. I can certainly imagine ways of implementing such a scheme - something like a shared resource file that all the files refer to. This will require mods to .osg and .ive plug

[osg-users] Sharing statesets across files

Is there a way of including a proxy stateset node or referencing a stateset stored in another file? I am trying to split up a single model into smaller pagable chunks. However, my original model makes significant use of shared statesets to maximise reuse of textures. When I break up my model each l

Hi Paul, All I can say is welcome to C++ :-) Occasionally one has to cast away constness for the sake of convinience and to avoid duplicating many code blocks that otherwise would have to have both const and non const versions. When you cast away constness you are effectively taking the law in y
