Re: [osg-users] Generating multitouch events

Hi, Thanks for your replies, it confirms what I was thinking... The iOS way of sending events seems to be an exception, all the touch technologies I use (mostly MPX, Windows 7 and TUIO) send them separately, so I think it should be useful to add to EventQueue a way to track the events to put them

[osg-users] One more texture on earth

Hi! I have model of earth and 2 maps as texture on it - daylight and night texture. I need to load one more texture - for example more detailed map of some region or city. How can I do it? This is my code , which realizes 2 textures: Code: sPlanetSphere-setVertexArray(coords);

Re: [osg-users] True Geometric Morph

Hi Seth, I implemented osgAnimation::MorphGeometry when I was working on the Collada importer and needed a way to store the morphing data inside a Collada file. The morphing algorithm is indeed very simple, but that's typically how morphing animations are exchanged in the 3D content pipeline.

Re: [osg-users] True Geometric Morph

Hi Seth, The OSG doesn't have this general morph capability that you are looking for. It's not something that is something that can easily be done with blending geometries as you'd need as working out the correspondence will be none trivial. The way to tackle it would be to leverage the

[osg-users] Keyboard move camera position

Hi, I've created my 3D scene, and now I want to move camera's position in this scene, using keyboard controlling, like using some key lik A, S, W, D to move the camera... Is there any simple example of using keyboard handler? ... Thank you! Cheers, Nan -- Read this topic

[osg-users] IFC to OSG converter

Hello, I am working on an IFC to OSG converter. There are some screenshots at www.scenescript.com. Regards, Peter Kilpatrick___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] IFC to OSG converter

Hi Peter, Nice work! Is this a ReaderWriter or a standalone converter? Sukender PVLE - Lightweight cross-platform game engine - http://pvle.sourceforge.net/ - Peter Kilpatrick p...@scenescript.com a écrit : Hello, I am working on an IFC to OSG converter. There are some screenshots

Re: [osg-users] IFC to OSG converter

Hello Sukender, It is a standalone program that reads an IFC file, displays the spatial structure tree and creates an OSG scene graph which can be output. IFC files tend to be very large and take a long time to load so standalone is better. The resulting .ive files are much smaller and load

Re: [osg-users] IFC to OSG converter

You probably still want to implement osgDB::ReaderWriter. You can still use a standalone import/export program that loads the IFC file using osgDB::readNode() and saves to IVE using osgDB::writeNode(), such as osgconv or your own specialized import and visualization tool. On 2/8/2011 8:17 AM,

[osg-users] Forward declarations and ref_ptr members

Hi all, I'm trying to prune out the number of includes in my headers, in order to keep from including OSG in all parts of my application. I have a couple of places where I would like to forward declare osg::ref_ptr, but so far I have had no success with that. Specifically, I would like to

Would the pimpl algorithm be applicable to your situation if you want to minimize compile time dependencies? On Tue, Feb 8, 2011 at 2:50 PM, Jesper D. Thomsen j...@anybodytech.com wrote: Hi all, I’m trying to prune out the number of includes in my headers, in order to keep from including OSG in

Re: [osg-users] Forward declarations and ref_ptr members

Hi Jesper, error C2079: 'asg::ASGContainer::m_osgroot' uses undefined class 'osg::ref_ptrT' Template classes/methods need to be completely defined when they are used, so what you're trying won't work. In addition to using the pimpl idiom which would completely solve your problem but might

Re: [osg-users] True Geometric Morph

Well all right then! I've got so much on my plate these days I have no idea if I'll get to this right away (or at all) but if I do, I think doing it in OSG is the way to go. I've got a good source on all the morphing research that came out of it's flash in the spotlight back in the 90's

[osg-users] osgPPU HDR culled from certain angles?

Hello all, hello Art :-) I have been experimenting with osgPPU's HDR example, and it looks and works great for my purposes, and was even easy to integrate into my own app as a test. It's interesting how easy the code is to understand, given what it would have been without osgPPU (i.e. using

[osg-users] Shaders in StandardShadowMap

Hi, I suggest altering one line of the shader code of StandardShadowMap into: (_mainFragmentShader) color *= mix( colorAmbientEmissive, gl_Color + gl_SecondaryColor, DynamicShadow() ); \n Otherwise no specular light is shown. Also it would be nice having a chance to using the existing

Re: [osg-users] True Geometric Morph

Okay, I did some reading and I think this should be fairly easy! What we need is 'combinatorial compatibility' between the two targets (i.e. a 1 to 1 mapping between vertices and edges). The book by Gomes et al. describes several ways to achieve this but the simplest one that doesn't require

[osg-users] osgWidgets and double click

Hello, It seems like osgWidgets doesn't support double-click. What would be a good way to implement it? Timing the clicks on my widget manager doesn't work, because I always miss the second click. I think that is because OSG's event handler is translating the second click into a double-click and
