Yeah I'm definitely planning to have "baked" lighting which recomputes (for some subset of blocks)…
Why C++ doesn't define NULL as nullptr is because idiot programmers used NULL as the 0 constant, …
This issue is not Microsoft compilers fault. This is C standards fault. If C compiler doesn't see …

Ok that is really weird, I forgot to include string.h now the warning is gone. I really don't want…
Since you're not including string.h, I guess you're implementing strstr in mylib.c. Does your fun…
Maybe you could fake some static global illumination? If your world is constructed of cube voxels …
Yep! I'm removing all voxels surrounded by others as well as redundant faces. I'm also optimizing…
C++ isn't the only language with mistakes in its design. C has its fair share, among which null-te…
The reason NULL is used is because of the issue of dangling pointers. You know what pointers are, …

Sorry maybe I don't undestand: You swapped c and c++?, in that case I get it. I'm compiling in c…
C has many mistakes in its history, defining NULL as 0 (an int) instead of a special ident like nu…

I'm a bit confused about the NULL constant, while doing this exercise on the k&r book: -x shows t…
Since I'm going to be getting deep into lighting with , I'm wondering, what are some of the simple…
Are you only rendering voxels which aren't surrounded by other voxels?
The (n-1) is a correction for sample variance instead of population variance. Both versions are …
You could try generating the world in a deterministic way. A random number generator requires a se…

You can view subtraction as being the composition of addition and multiplication by -1, i.e. 1 - …
-2xu = -1*2xu It's just pulling out a constant multiplier, which comes out in front of a summatio…

Since subtraction is anticommutative I don't think that you can make that jump. But I am not entir…
Okay, so I re-derived the formula and you are correct, I got it wrong. Here's the correct deriva…

Those two formulas are very different and produce different results as far as can tell, so no they…
