Re: [osg-users] [osgOcean] SkyDome with a repeating Texture2D

Hi Kim, Thanks for the reply. Well, I know it is only to showcase the osgOcean but still we need something to show the atmosphere / (at least) the sky. Currently I am using the skydome in my project because I don't know anything that's better. Now the problem is the skydome is always stretched

[osg-users] [osgOcean] SkyDome with a repeating Texture2D

Hi, First of all, I would like to ask a permission to use and modify the SkyDome used in the oceanExample and make it into a separate library. I know that it is not really a part of osgOcean library, but I reckon that the devs should be the same. So I asked the question here. Like the title

Hi, Ok, after many googling (and stumbling around aimlessly) I've found a similar situation (and a revelation): http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2008-April/009746.html So I think I'll try that one suggestion. Adding another camera pass that will only

Re: [osg-users] [osgOcean] Shader again.

Hi, I've tried meddling around and put camera-setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR); on both the cameras of OceanScene::renderToTexturePass() and OceanScene::glareCombinerPass(). The results are: 1. If I put it on the RTT method, it will cause the glare to be

Hi, I seem to stumbled a lot on osgOcean's shaders. I've got lots of graphics artefacts because of them. Can you point me to the ones that are actually working on them? I may need to disturb them a bit with my questions. Thanks. Oh yea BTW I've successfully made my own bloom shader. Here's the

Hi, Nevermind. I've found my mistake. I was just wondering why it didn't work and the texture can't be loaded from the shader. It's all because my own stupidity of using sample2DRect instead of sample2D. And I've just found out that the base texture from an ive is actually pre-determined as

[osg-users] [osgOcean] Greetings, and a few bug.

Hi, I actually have been using osgOcean for a year now. Well, I actually use Delta 3D which uses OSG and in turn osgOcean. It's a pretty good library for rendering ocean, would be better if you can add atmospheric scattering using Mie and Rayleigh approximation for real time day-night
