Oolite Bulletins

These are from my attempt to "move" the planet textures creation in the shader. Even for only the diffuse + spec + normal, I'm not sure what would be the hit for older graphic cards. Looking good! Commander_X - are you doing this with code changes or using plists and providing the vertex/...

If interested, I can send the Blender file I'm trying to munch on for creating these maps. I think that will be the better distribution for this, considering the size of the files for _not-even-half_ of G1. No rush - same reason I don't have blender installed as oolite, not for work laptops. Povray...

I've been reading the default planet shader and it looks like normal maps with cube map is supported. What makes me curious is how you've reproduced the 'hairy ball' tangent space with blender to get these awesome normal maps. I had always assumed that cube map normals would need to be object space ...

That is a literal edge case - there are some comments in the planettool code for Cubes about that. What do you see with cubex in passthru ie: planettool -i cubex input.png -o cubex output.png --size <as-per-input> There is probably a special case for cube to cubex and the reverse transform where rot...

Possibly something to do with texture binding. I'm not sure how planettool treats the individual faces , but assembling the TEXTURE_CUBE in opengl may have some texture wrapping by default. See link regarding skybox (the traditional use of cube map textures) https://gamedev.stackexchange.com/questio...

2. The initial package has only Earth like variants. As mentioned above, I used Povray Planets as a source of inspiration, and tried to cover this initial type of planet. As a reference, I classified the G1 Povray Planets in 5 main types: Terran (119), Barren (115), Water (7), Winter (5), and Gas G...

Further to this - I have managed to get the rendering pipeline built again. Even when rendered with each side at 1024x1024 , I can still see a seam when converting with planettool to mercator or cubex. I had suspected that the povray antialiasing being enabled was part of the problem - sadly no :( -...

I overlayed an original povray planet image to compare quality, size. The converted image was shifted 1 pixel horizontal and 1 pixel vertical, image quality showed a little blur. Thanks cbr that illustrates it really well. Is this the entire image being shifted? The blur might be explained by a sub...

Cool! Good to see you, sub!

Thanks mate. I miss this community. I also miss having time to spare on hobbies. I've been doing a round of tidy up for old projects and povray planets was in need of some love.

Not sure if it's related. I'm seeing this small seam on Lave with Povray Planets 1.1

A-Ha! some of the textures in povray planets 1.1 are actually from Famous Planets and those were not originally cube-maps. I wouldn't be surprised if they have seams.

FYI The original povray planets release post now updated with links to all galaxies.

Please, reload the archives to gdrive because galaxies 4,5 are missing.

Better - switched over to cloudflare and a domain for itself. Please see initial post for updated links.

And more for scientific purpose... The equirectangular map from an earlier post converted to a cube map [option cube] via the powerfull planettool https://i.postimg.cc/mrxFVDfm/oolite-139s.png It shows a tinier seam than the povray cubemaps which make me think the povray cubemaps were converted a b...

The file is no longer at the stated location.

Links fixed. All content previously referred to by domain 'swarm.perlide.org' can be found at 'assets.povray-planets.org'

On trunk when. .. this year maybe? Worst developer estimate ever. Looking at github - I don't think shady-planets has moved along since I lost motivation and disappeared for many years. Digging through the changelog for oolite it does not seem like anything similar has landed for planets + atmosphe...
