Hi Rick,
I'm trying,
Hi Folks,
I started my subscription with Terragen.
Well after 4 hours of Ray Trace rendering on a fast machine - I have the very first 10,000x10,000 Pixel (240MB) Skydome in ORTS that I'm aware of.
While it has the potential to look very good in ORTS - the attached image clearly illustrates the problem with SkyDomes as we have them now. The closer you get to the horizon the worse the distortion gets. Each face on the shape that holds the Skydome texture is 15 degrees in the horizontal which introduces massive distortion. Honestly - unless we can do something to increase the number of faces on the shape to reduce distortion - it doesn't seem worth while to continue on this path of producing realistic Skydomes.
100,000,000 Pixel Skydome
Regards,
Scott

Hi Randy,
Hah - they were just a preview at 1024x1024 pixels - - - I'll get you a 7500x7500 and 10000x10000 to play with.
I work on this in two locations and while my Kaby Lake can crunch a 100000x10000 pixels in four hours - - - I left the same file running on my Sandy Bridge for eight hours and it was only 10% done. I'll crank out some new high resolution Skydomes when I get home this weekend on my good machine.
Regards,
Scott

Hi Mervyn,
Yeah - I've looked - I can't find anything resembling a shape for the Skydome. I'm assuming it's computed at run time. I'd love to have a chat with someone in the know on the code. Even if someone could identify the block of code where this function resides - possibly posting it for us to review and have a conversation - would be helpful.
While I think we should have more faces on the Skydome - the texture application on the hemisphere is obviously stretched by whatever method the developer used and it really doesn't have to be. This "Fisheye" texture can be applied to a hemisphere in modeling software without the stretch being illustrated by my red line image posted above.
Thanks for the interest.
Regards,
Scott
