I need to create rings for Saturn using DGDK by which I mean I'm not using any models, I need to do it using the built in functions.

A code snippet would be nice.

Thanks

You need to? Here's the type of mesh you'll need: http://www.rockin-b.de/saturn/saturngametutorial/SGT_blenderPlanetRing.png, it's easier to make this in some 3D modelling app and just load it, but you could also make it using code, i.e. via memblocks or something. Luckily for you, there are millions of threads detailing the usage of FVF structures and how to create memblock meshes in general! And assuming a rather basic knowledge of trigonometry you should be able to make this using said info on memblocks easily.

You could manually use a bunch of flattened cubes and make a circle.

The real saturn rings are made from asteroids or some kind of rocks so you could create a bunch of spheres but it will take a lot of memory so don't know how will that work.

Uh, why not just take a... 4 pixel wide by 860 tall image that has the ring texture on it, then make a function that takes the image, puts it on a plane, and copies that plane in a circle around the planet?

If I were you I would do this:

-Get IanM's Utility DLLs.

EDIT: I just realized you're using DGDK, so I'll look for an alternative to the filled circle function.

-One of them has a command to make a filled circle. So make an image with a black background, then draw a white filled circle, then a smaller black filled circle. (you can replace white with any color or pattern you want to make it look better) You'll end up with a ring:



-Set the transparent color to black and get the image with 'Get Image'.

-Texture a plane with the image and set the transparency on.

Then you should have a ring. You might also want to set the backface culling off so you can see it from below as well as above. Obviously this won't be the most visually appealing method but it gets the job done efficiently.

90% of statistics are completely inaccurate.

Any chance you could gove me some code? I tried setting tranparency but i just made the whole plane grey.
