Re: Re: A new 3D Globe image for Terra
Yes, the 3D cloud rendering needs higher vertical resolution (i.e. devision of the IR temperature into more slices) to reduce the Vencian blind effect....

Re: A new 3D Globe image for Terra
The cloud rendering would look more realistic if the cloud database were interpolated to much higher resolution before the 3-D projection, so that individual...

Re: A new 3D Globe image for Terra
The cloud rendering has a strange on-off "venetian blind" effect with altitude.
