Well I don't like EverQuest Oblivion as I have already seen more than 10 games where there were beautiful greenery. But a very good such example to note-not for playing in this case, but for game development-is the first Far Cry. The level of detail there is insane...stealth in the tropical jungle forest on an island which has half-transparent sand water, with white sharks circling the multiple sea docks. The theory they took there to allow such memory and GPU overhead handling-was basically to realign the light system by populating more of the island by dense jungle forest, meaning less sun's lighting rays from any direction.

That's 2GB for an 800 km diameter planet at about a half meter resolution. It's procedural and uses an aggressive LOD system.
I've only been programming since 1981, but remarkably I've already learned how to comment code.
I wasn't talking about commenting son...I just suggested the standard commenting style...you most probably know this as well, but it was worth noting.

As he stated, it was a small example code. So there is no need for documentation here. Only some comments for hard to understand code sections would have been nice ?
Not quite. I would like a detailed commented explanation in the code to see what you think a class represents.
Three of your code examples:
In the first you should try data encapsulation.
In the third, use explicit data cast converting. You use it but not in every case. Also use smart pointers. Here is what I suggest for the voxels:
//Planet.h
#include "Voxel.h"
#include <utility>
//Include graphical library files here
class Planet
{
private:
std::unique_ptr<Voxel> building_blocks{nullptr};
};
//Planet.cpp
//Voxel.h
#include <array>
class Voxel
{
private:
int oct[8]{0};
public:
Voxel(int set1,int set2,int set3,int set4,int set5,int set6,int set7, int set8);
Voxel(std::array<int, 8>& oct_arr);
};
//Voxel.cpp
#include "Voxel.h"
Voxel::Voxel(int set1,int set2,int set3,int set4,int set5,int set6,int set7, int set8)
{
oct[1-1]=set1;
oct[2-1]=set2;
oct[3-1]=set3;
oct[4-1]=set4;
oct[5-1]=set5;
oct[6-1]=set6;
oct[7-1]=set7;
oct[8-1]=set8;
}
Voxel::Voxel(std::array<int, 8>& oct_arr)
{
for(size_t iterator{ 1 };iterator <= 8; iterator += 1)
{
oct[iterator - 1] = oct_arr[iterator - 1];
}
}
