I would > appreciate any insight you could provide! Thanks for pointing this out. The artifact you are seeing is a result of the way we create the textures that get displayed. For efficiency, each texture ends up being a collection of 10 radials (making up the wedge). I've made a change for radar displays that sets the texture size to 1 which displays each radial as it's own texture. This will slow down the rendering a little, but give you the desired effect. This is an issue with any radar data, but we haven't noticed it on the Level II data because there is usually missing data at the outer reaches of the sweeps which ends up being transparent. I was able to reproduce this with some Level II velocity data though. The fix will be in tonight's nightly build. Also, we are looking into some display issues with the DORADE data. We have not used the DORADE data much, so let us know if you see inconsistencies between the IDV and other display programs.
