Hi, Paul and Michael Frist Thank you for your suggestion. I use the your method, and output show correctly in normal rendering, but when I use my deferred render, it has aliasing, I use a TextureRectangle as normal_sampler, below is my fragment shader: #version 120 uniform sampler2D

Re: [osg-users] [osgOcean] Error with osgOcean-VBO Example!

Oceansurface wasn't initialised, I've fixed and checked this in to the branch. Only additional hardware requirement is VBO support which I gather is pretty standard. If you find that you have problems with this you can disable the use of VBOs in the FFTOceanSurfaceVBO constructor and recompile.
