tom95521 Posted December 15, 2012 Report Share Posted December 15, 2012 For my space slideshow I want to visit distant planets but I need to tackle this problem first.How can I make a realistic rotating globe without using a movie or animated gif and not having the option of using displacement mapping?What I am trying to do is create a rotating globe from a mercator projection map of the Earth. Slide 2 splits the Earth into upper and lower hemispheres with +/-30 degree rotate X transformations. I think slide 2 does look better than slide 1. Now I want to split the Earth into 4 quadrants by adding 30 degree Y transformations. I'm guessing it will require more masks maybe with zones like in slide 3?I'm hoping Lin or someone else has an idea. I know the easy answer is to use a movie or gif loop but I would not learn anything.Thanks,Tomearth_transformation.zip Quote Link to comment Share on other sites More sharing options...
xahu34 Posted December 15, 2012 Report Share Posted December 15, 2012 What about using Blender?Best regards,Xaver Quote Link to comment Share on other sites More sharing options...
xahu34 Posted December 15, 2012 Report Share Posted December 15, 2012 I got the impression that FT3 produces static images.Regards,xaver Quote Link to comment Share on other sites More sharing options...
xahu34 Posted December 15, 2012 Report Share Posted December 15, 2012 ...Apparently you can combine images into avi video using VirtualDub....Good luck! I'm sure you will show us your results Regards,Xaver Quote Link to comment Share on other sites More sharing options...

Didn't find what I wanted yet. Off to bed now.Regards EricYachtsman1earth_transformation.zip Quote Link to comment Share on other sites More sharing options...
fh1805 Posted December 17, 2012 Report Share Posted December 17, 2012 My technical problem is vertical masks. If you look at slide 3 you will see that I want to create 5 vertical sections. Inside each vertical mask (rotated either 0/30/60 degrees) will be a copy of the 5 horizontal sections (hope that makes sense).Tom,If I understand you correctly, you are thinking of nesting a mask container inside another mask container? That cannot be done in PTE. Whether it could be programmed into PTE by Igor and his wizards will depend upon the library of graphics handling routines that they use. What are you trying to achieve by your proposed improvement? A more realistic impression of the curvature of the Earth?regards,Peter Quote Link to comment Share on other sites More sharing options...
