LOL even though that would be awesome, in this case it's about the Nether and the End. :P

Hum, due to our impossibility to interpret 4D environments, I don't especially think that would be awesome :P

It's interesting to think about extending the smooth randomly generated terrain to another dimension you can only see a slice of, though.

The Universe is infinitely dimensioned. :P Also if you remember my explanation, Time is a plane. We only perceive it as a straight line though but that's still 4D that we can perceive although our eyes only provide three. ;)

I think that a working crafting would be a essential part of the program!
and by the way this is AMAZiNG!!!

I've got something unexpected for you: Monochrome crafti!
   

It also supports the clickpad. I added no new features, so please use v0.9 if you have a CX.
The red part dominates the pixel brightness, so water is black and lava bright, but everything should be recognizable.
I don't have a non-CX calc, so I couldn't test it on hardware, but it works in nspire_emu in clickpad mode. Touchpads should also work.
And BTW, I fixed some compiler errors if you were using nGL with SAFE_MODE without TEXTURE_SUPPORT. But AFAIK, nobody does.

Unexpected, but much waited for ;D

Nice work, I'm definitely downloading it now !

Then please tell me if and how well it works! If it's not too bad I might add some texture preprocessing so it looks a bit better.

I hope the blur isn't too bad; I tried nDoom on a friend's non-CX calc and it was really hard to tell what was happening.

So everything works as far as I've tested things (Ndless 3.1 r914) ; the blur is indeed very annoying (but can get better if you fiddle with the contrast), and it would be cool if you could diffuse brightness equally according to the whole pixel and not only what seems to be the red channel. I'm pretty sure I saw a formula for converting RGB colors to an arbitrary gray level, but IIRC it implied 3 floating-point multiplication - I'm pretty sure you can deal with it with fixed-point though.

So it's okay to play with? If not I'll abandon monochrome crafti.

Yeah I had this problem, although for me nDoom ran slightly slower than other platforms on the clickpad so that kinda solved my blurring issue. gbc4nspire, on the other hand, was completely unplayable with some games. Blame TI :P

This should look a bit better. There are some issues, but it works well overall.
Weirdly, even though I set 16-bit mode and each pixel is 16-bit wide, only the lowest 5 bits are used. So it wasn't red, but blue...
