Greetings Forum,

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]To begin with, recently I decided to work on[/font][color=#000000][font=Verdana, Arial, Helvetica, sans-serif] [/font][color=#000000]Isometric engine[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

. However, it was simply too boring.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]So, I came up with an idea to make [/font][color=#000000]Voxel[color=#000000] [color=#000000][font=Verdana, Arial, Helvetica, sans-serif]based isometric terrain for the game.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]Before the main post, the programming language I use is BlitzMax which is rather slow.
However the code I have written can be simply rewritten in C++, since the syntax is only thing that differs.
I have attached the files to the thread, Terrain demo's works on OpenGL, in case you have some problems, tell me. Tile system demo works on DirectX.[/font]
[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

I may compile it for DirectX or vise versa in a minute.[/font]

1. Voxel Based Terrain[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif][size=2]

Note: Demo Applications Are Attached To The Post[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]At first, I made isometric tile based terrain which supported some height values [/font](1st part)[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]Secondly, I used [/font][color=#000000]Cubic Spline Interpolation [color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

for both, X and Z axis to create smooth edges for the terrain.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]That way I created prime voxels. [/font](2st part)

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]Later, I found a solution to draw voxels properly [/font](3rd part)[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

, though the method is rather too slow for real time rendering.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]4th part shows how I implemented texture displaying on the terrain.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]Terrain collisions already have been implemented.
In the end of terrain development I also implemented lighting + map bumping.[/font]

[font=Verdana, Arial, Helvetica, sans-serif][color=#000000]The practical use of engine's terrain would have been:[/font][color=#000000][font=Verdana, Arial, Helvetica, sans-serif] export the voxel [/font][color=#000000][font=Verdana, Arial, Helvetica, sans-serif]terrain as image tiles and use it in the game.
That was the progress with voxel terrain:[/font]

2. Voxel Based 3D Tile System + Destructible Terrain[/font]
[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

Note: Demo Applications Are Attached To The Post.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]Well, to play with voxel engine was quite fun![/font]
[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]I have accomplished terrain system in just couple of hours and wanted to try something more complex.[/font]
[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]The next step was to create 3D tile system. I did it and implemented[/font][font=Verdana, Arial, Helvetica, sans-serif][color=#000000] [color=#000000]Destructible Environment[/font][color=#000000][font=Verdana, Arial, Helvetica, sans-serif] as well.[/font]
[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]I found a lot of optimization methods, but I had one simple problem to which I still do not have a solution.[/font]
[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]Unfortunately, I didn't found any proper way to create fast real time 3D voxel bumping/day lighting.[/font]

[color=#000000][font=Verdana, Arial, Helvetica, sans-serif]

My results so far

3. Voxel Engine Basic Platform & Physics (OpenGL)[/font]
I've also attached demo file so you can check it out :}
Controls: Space and Arrow keys.

My achievements:

1. Fast voxels drawing with depth
   
2. Simple and basic lighting
   
3. 256 colors for voxels
   
4. Create or move loaded voxel objects

Enjoy, I hope you find this interesting!
Waiting for feedback :}[/font]

It has voxel map of the size 1024*224*1024 and needs about 235MB Ram.

You can notice that there is no initialization time.

Probably that's where my journey with engine development ends.
I have no further ideas to implement, except to rewrite it in C++ and improve speed like 2-3x times.

PS: If there will be requests, I might share some of the source or make a tutorial ;}

A tutorial would be great!

***UPDATE*** Voxel Engine Basic Platform & Physics (OpenGL)

I forgot to mention that I was working on Voxel Based Real-Time Platform Engine.
I've also attached demo file so you can check it out :}
Controls: Space and Arrow keys.
