Well, that worked perfectly. I'm still not 100% sure why it works, but I'll learn. I appreciate the help

I did, afaik, everything you explained. It's rendering lines now, but they're rather... weird. It should be outlining the Andesite block, but it definitely is not.

I'm trying to render a block's bounding box as a solid color cube that can be seen through other blocks. I've searched for a few hours for a method that is both up to date and working but have had no luck so far. I haven't worked with 3D rendering before, so I am trying to use this as a basis to get started, so please forgive me if I ask too many questions. If you are unsure what it is I am trying to accomplish, try googling "chest finder" and looking at the images. (P.S. No, I am not making another hacked client) I don't wish to be spoonfed code, but I need help getting pushed in the right direction. Cheers!
