Re: [osg-users] osgViewer::setSceneData calling sequence with osgUtil::Tessellator

Hi Yu, Could it be that you haven't done anything to update the position of the viewer Camera to account or the scene that you've just updated? My guess is that it's simply that the viewer's Camera is still in it's default position looking at the center of the empty canvas node. Robert. On 18

[osg-users] osgViewer::setSceneData calling sequence with osgUtil::Tessellator

Hi experts, I have 2 piece of code, use tessellaor to extrude and hole generation. Looks the setSceneData should call after hole tessellation operation, otherwise the viewer will draw nothing. Could you please advice on how to setSceneData the root nodes in the begin of application, and update

Re: [osg-users] How do I get a reference viewpoint from a DrawCallback?

I tried your suggestion, but the camera stack is always size=1, with only the current camera on top (be it the main cam or the RTT cam). I am still trying to track down why that is. (OSG 3.3.2) Glenn Waldron / @glennwaldron On Fri, Jul 18, 2014 at 7:31 AM, Robert Osfield wrote: > Hi Glenn, >

[osg-users] Light-Linking in OSG

Hi, I had a question relating to any known approaches of linking lights to specific geometries in a scene while ignoring others. I have been building my assets in 3dsMax and using the exporter to get an OSGT file which provides the model, textures, light and cameras. The linking I do in 3dsMax

HI Saravanan? Have a look at the osgdistortion example for how you can render to texture and reuse the result when rendering to a screen aligned quad. Robert. On 18 July 2014 13:31, Saravanan Sivaprahasam < saransivapraha...@rediffmail.com> wrote: > Hi, > > I have a scene to be captured by ca

[osg-users] [osgPlugins] osg store user values

Hi, Is it possible to force osg plugin to store user values for nodes (set by setUserValue() method from osg::Node) somehow? Maybe using osgDB::Options, but haven't found any solution. Or only solution to store nodes with user values is writting separate plugin? Thank you! Cheers, Robert ---

[osg-users] FBO and Render to Texture

Hi, I have a scene to be captured by camera and render it to a texture. I am applying shaders to post process the scene and draw the scene as texture to a scene aligned quad. I need clarification regarding applying shaders and drawing the scene. Does it needs to implemented as camera callbac

Re: [osg-users] assume render order?

Hi Bram, The rendering order is controlled by the type of RenderBin that the drawable leaves are dropped into during the cull traversal. If the drawables are in the default opaque bin then they'll be sorted by state order, the traversal order will have no effect on the draw order. If the drawabl

Re: [osg-users] How do I get a reference viewpoint from a DrawCallback?

Hi Glenn, The RenderInfo object maintains a stack of Camera which you should be able to use to get access to parent Camera's to the current Camera. With the computation I would suggest you convert the centroid into eye coords of the RTT Camera like you are doing then convert back into world coord

Thanks Robertos and Farshid. Robertos, when I said: "What are the steps that are involved in building the libraries, and loading them as plugins? " I actually meant to ask this from the perspective of the 'system', and not the steps that a user has to take to make it work. This demonstrates wha

[osg-users] assume render order?

Hi, I was wondering what kind of assumptions I can make about the rendering order. for example in kinda pseude code: rootnode->addChild(node1); rootnode->addChild(node2); node1->addChild(node3); node1->addChild(node4); node3->addChild(node5); would give: rootnode -> node1 -> node3
