World Map Testing

Really nice! I love the colors. (Did you calculate how high those mountains are, vs. the planet's diameter? They look pretty high!)

Neato! Nice one!

I faked it - they are just a bump map, not really a height field. (I think I overdid it on the bump scaling factor

On that note, however, I remember looking at aerial photo stereo pairs back in university that effectively hyper magnified elevation because of the exaggerated spacing of the photos...(5 minutes of googling later...) Like this one:

You need shadows under your cloud cover (maybe like this: http://www.arcticcoconut.com/arcticc....supersize.jpg).

I still really like it, though. It has that je ne sais quoi.

I did one in stereo...just for fun...I didn't bother with the atmosphere or stars, but I did get some semblance of cloud cover and my clouds cast shadows...sorta. I also experimented with some water methods...This is actually three spheres...one is the displaced land mass...the other is the water sphere that cuts through, which is 50% transparent...and the other is the cloud layer.

What you wanna do here is look at it, and cross your eyes, so that the images overlap creating a middle image that is combined between the two....look up the effect online if you want more info, or I can explain it better in another thread I guess.

Software used: 3ds Max 2008 (A&D Materials, mental ray renderer), gwTerraNoise.

That stereo version looked like fun, so a few minutes of tinkering with POV later....(also a cross eye stereogram)



I changes the camera position slightly to get more shadow.

töff - the clouds do cast shadow, but they were a bit too close to the surface to show up. I increased the cloud elevation and opacity a bit this time.

Also- if anyone wants the (very simple) Povray source code for this scene, just let me know. All you have to do is change the bump and image map parameters, and you will get the same scene with your own planet.

I think but I'm not 100% sure that your images are crossed...For cross-eyed stereo pairs the images should be RL instead of LR....

To me the globe looks like its sunken in when I cross my eyes...so reversing the two will fix it...Like attached.


I've done a LOT of experimenting with Stereo Pairs...so much so that I made a program that lets me quickly create the pairs in one image...attaching

[RobA]

Thanks - That is a lot better! I wondered why I was getting a headache looking at mine that got worse the more I spaced the L&R images apart!

Thanks for the little program, works great!

That's really odd, for me, the image RobA posted originally looks convex and the reversed one posted by Arcana looks concave on the bottom left corner of the planet. I must have reversed eyes or something!
