Re: [osg-users] bluring model edges

Harash, now I understand what you were talking about. I am attempting to use the hdr example from osgPPU to perform the following procedure you outlined. However, I am having difficulty in breaking out the blur section of the hdr example provided with osgPPU. Could you possibly tell me what

Re: [osg-users] bluring model edges

Hi, does anyone know where the examples are for using osgPPU? I can not find any on his sight. And documentation, too, that is more than the class layout offered on the sight. I need deeper explanations than just class/method blurbs. Thank you! Cheers, Allen -- Read this

Re: [osg-users] bluring model edges

Guy and Julia I still can not get this code snippet to work. Would you please tell me what I might be missing? I've provided my sample code and have commented out the code snippet below because I could never see any changes. Guy wrote: Julia, I never tried it but you should enable

Re: [osg-users] bluring model edges

Hi, Morphological Antialiasing (MLAA) is a Post Processing technique. you could try with osgPPU. ie can this methodology be performed in milliseconds? : Like other Post Processing technique, it's depend of your shader complexity and your output resolution. An example :

Re: [osg-users] bluring model edges

Guy, I have tried this code snippet, too, and I am not getting any results. None. No changes in the look of my model or a constructed pyramid. Could you perhaps tell me what I am missing? I have attached my blend app, which is a direct copy of the blendequation app from the OSG website. I

Re: [osg-users] bluring model edges

Thank you Yann. Does anyone know how to install osgPPU on windows? I'm close but I am getting errors that gl.h can not be found, yet I've installed OSG by following the osg installation method given for windows xp. I had to install cudatoolkit from nVida - I'm running on an nVidia card:

Re: [osg-users] bluring model edges

Hi Harash. Well, I truly do not know what you're talking about but I kinda understand in principle. Would your methodology work in a real time simulation - ie can this methodology be performed in milliseconds? 2nd question: where would I start? I've no idea how to render a scene to a texture

Yann, can this be perfomed in OSG? yann le paih wrote: Hi, Morphological Antialiasing maybe an other solution : http://visual-computing.intel-research.net/publications/publications.htm (http://visual-computing.intel-research.net/publications/publications.htm)

Re: [osg-users] bluring model edges

Hi, I am in need of this type of feature, too. I need to be able to take a model fuzz it's edges, though I must admit that I don't fully understand the code given, I'll try this. Thanks Guy for the ideas. Cheers, Allen -- Read this topic online here:

Re: [osg-users] bluring model edges

oh really so it is meant to just effect the edges? That is great to know that this functionality is supported. I wonder why it causes the skeleton of the model to show through (see attached screenshot for what Im talking about) I am not very familiar with the OpenGL state settings - do you

Re: [osg-users] bluring model edges

Hi Julia, If you use pure OpenGL to render the model, with the polygon smooth state enabled, does it have the same effect? Guy. -- oh really so it is meant to just effect the edges? That is great to know that this functionality is supported. I wonder why it causes the skeleton of the

Re: [osg-users] bluring model edges

hi Guy, I tried this code and didn't notice any blurring, although for some reason the skeleton in my models became exposed (the same effect as the osgscribe example). If I understand right this example is meant to blur the entire model - is that right? Because I just want to blur the model

Re: [osg-users] bluring model edges

Well, It should have given fractional alpha values only on the object edges... It would be interesting if you could check your object using a pure OpenGL code. Maybe it's a card issue, maybe there are other modes that interfere... Sorry it didn't help, Guy. -- hi Guy, I tried this

[osg-users] bluring model edges

Hi, Is it possible to blur the edges of a model in OSG with whatever is behind? Currently the edges of the models in my scene are too sharp and would look better if there was a translucent overlap at the edges. Is this possible to achieve in OSG, or is this kind of functionality more relevant

Re: [osg-users] bluring model edges

Julia, I never tried it but you should enable GL_POLYGON_SMOOTH, and enable alpha blending for the object you want to 'blur'. For example: osg::StateSet * stateset = geode-getOrCreateStateSet(); stateset-setMode(GL_POLYGON_SMOOTH, osg::StateAttribute::ON);
