Amiga Breathless for PC

The remake of Breathless was an old dream of when I was 14, along other titles like Gloom, Alien Breed 3D, Super Stardust, Mario 64 and so on. This work is part of another bigger project that is called TextureMind Framework, developed to facilitate the creation of these kind of projects, like games, demos, presentations and so on. The idea to make a remake of Breathless in this moment started when I saw that the 3D engine with Vulkan was stable enough to render any kind of map imported with AssImp library. So why don't import Breathless map and use the same 3D engine to render them?

I was amazed by the idea of rendering Amiga Breathless with Vulkan libraries. The biggest obstacle was to import the maps from the old format in GLD, that was more suitable for raycasting than polygonal rendering. I started downloading all the material from Aminet, with this link:

Then I studied the format from the original source code in C, in particular the map editor. The first important obstacle was that the editor was programmed for loading the map only in uncompressed format and all the maps were compressed in an unknown format called SLZ. I got 0 results on Google. I didn't know the format and I was about to abandon the project.

Super Mario Bros for Amstrad CPC 464

When i was a little kid I remember that i really wanted to create a Super Mario Bros game for the amstrad cpc 464. Now that I am 33 and I work as a software engineer I asked myself: why don't you make your old dream come true? :) Finally I found the time to create a demo with the famous first Level 1-1 of Super Mario Bro:

The horizontal hardware scrolling needs a double buffer in order to get an accuracy of 4 pixels. The demo runs on original Amstrad CPC 464 speed emulated by Caprice. It is pretty fast and can loop horizontally with a limit of 512 tiles meanwhile the level 1-1 takes only 212 tiles. I readjusted the original smb graphics to fit a 256x192 Mode 1 with 4 colors. I really like the effect of the gray scale map mixed with the blue sky, like in the original NES game. This demo has been programmed with SDCC in C and Z80 assembly.

Unrelated Engine – Work in progress

This is the first "work in progress" video of my 3d engine called Unrelated Engine. Some complex animated models come from Doom 3. They were converted to a maximum of 4 weights per vertex as well as the identical vertices have been cancelled to improve the speed. The shader language was used to obtain a large amount of skinned meshes and complex materials with a reasonable speed.

The 3d models are from doom3 and from, they were used only to test my engine and to make this video. The rights of these 3d models and the music are reserved by their respective authors.

Unrelated Engine – A nice test with Mario 64 map

I created a nice video with an engine that I'm still developing and that is part of my Unrelated Framework. It uses:

- OpenGL (to draw the graphics)
- DevIL (to import images)
- Assimp (to import 3d models)

The 3d models are from, they were used only to test my engine and to make this video. The rights of these 3d models and the music are reserved by their respective authors.

Unrelated Engine – Aquarium 3D

Aquarium 3D is a little demo of an engine that I'm developing for my framework. It uses a multithreading system with a thread for the physic engine and a thread that draws the graphics on the screen: the two threads are perfectly synchronized to maintain the best fluidity possible with different framerates.

The physic engine has a static number of iterations per second, in this case 30. It can obtain a good fluidity of movements also on higher fps of the graphics card (like 75 for example) upscaling the static framerate with a series of trajectory corrections. It uses also OpenGL for graphics,GLUT to open the window and lib3ds to import the 3d studio meshes. The fish models are property of this site:

CryEngine 3!

The version 3 of CryEngine is the porting of the version 2 for the world of consoles, supporting both Playstation 3 and Xbox360 (but still compatible with the PC). Check the following video to figure out the new features.

An old Mario64 clone (abandoned)

Years ago I coded a 3d engine to create my own clone of super mario 64. The name of the project was Chronicle Time Quest and it never reached its final release or a version that was remotely playable. Unfortunately it was abandoned years ago for lack of time, resources and interests. However, it was  usefull as coding experience and the result wasn't so bad at all, so I have decided to publish this video to show something about it.

Probably this project will be restored as soon as possible, with a new concept (probably similar to the mario galaxy one) and a totally new 3d engine. If you like this idea or the video or the concept or whatever you want, please, write a comment to let me know what you think about it. Thanks.

Texture Generation V1.0

This time it was a little bit harder. As you can see in this video, my engine can generate in real time very complex textures with the maximum detail at the maximum speed possible.

Each texture is generated in real time at the frame rate showed on the top-left corner of the window (the "generation" label).

- Lumps (512x512, 200 objs, 16 bpp, 345 FPS)
- Blobs (512x512, 16 bpp, 107 FPS)
- Perlin noise (512x512, 8 octaves, 16 bpp, 115 FPS)

Also, the normal map and the bump mapping are calculated in real time. I used 16 bit per pixel to have more precision when I get the normal map (for more informations check my High Static Range video). Precision and speed of this engine are awesome. The final result can loop in all horizontal and vertical directions.

CPU: Intel 2 QuadCore 2333 Mhz; RAM: 4 GB DDRII 800Mhz

High Static Range

This demo shows a new feature about the texture generation engine implemented in my Unrelated Framework. The normalmap used by bump mapping is calculated on the base of an heightmap generated with two different methods: Low Static Range and High Static Range. The enviroment bump mapping shows the difference in quality between the two ranges.

The first range uses only 8 bits per pixel that is too low to represent a continuous surface like the sphere generated in this example and as result we can see many rings on the surface during the light effect. On the contrary, an high range of 16 bits per pixel is perfect to have a light effect on a continuous surface infact we don't have any kind of imperfection. I could use the famous High Dynamic Range to generate the height map, but in my opinion it could be too expensive for the use of memory and the lack of speed (32 bits floating point per pixel, or 16 bits half-float has continuous conversions because cpu doesn't support it).

Tecniche di stampa tridimensionale

Avete mai sognato di poter materializzare alcuni oggetti tridimensionali di vostra creazione? Forse è arrivato il momento di acquistare una stampante 3d! No, non sto scherzando, non tutti lo sanno ma esistono al mondo delle stampanti in grado di fabbricare materialmente degli oggetti con la stessa rapidità di una fotocopiatrice.

Questo significa che avendo tra le mani questa tecnologia potreste progettare un oggetto o scaricarlo direttamente da internet per poi materializzarlo nella realtà: si stanno affermando delle tecnologie valide per rendere reale un oggetto virtuale. C'è da dire però che gli oggetti stampati sono composti da un materiale omogeneo simile alla plastica formato dalla interconnessione di strati di polimeri solidificati... quindi se avevate già progettato di scaricare un cellulare da internet per poi stamparlo potete scordarvelo perchè (per la fortuna dei venditori) attualmente non esistono ancora tecnologie in grado di fare una cosa del genere. Tuttavia stampare oggetti ha molteplici impieghi ed è ampiamente utilizzato nelle aziende per la fabbricazione rapida di prototipi.

Video sui giochi di nuova generazione

Quando ancora mancava qualche anno al rilascio ufficiale, la Sony fece circolare dei video in cui si mostravano anteprime di videogiochi con una veste grafica da urlo, tanto per dare un'idea di quella che sarebbe stata la potenza computazionale legata al nuovo processore Cell della playstation3. Si diceva che la console avrebbe permesso di gestire addirittura interi mondi... per rincarare la dose, altri video burla mostravano una fantomatica playstation9 del futuro composta solo da nanotecnologie che entrando nel naso del videogiocatore gli si impiantavano nel cervello e lo trasportavano in un'esperienza videoludica uguale alla realtà (non è una mia invenzione, c'è anche il video su youtube). Poi la PS3 fu rilasciata e tutte quelle voci di corridoio si spensero di fronte alla realtà dei fatti ed i videogiochi sul mercato mostrarono una veste grafica mooolto più contenuta di come si era voluto far credere in passato. Un esempio? I vecchi trailer di Motor Storm ne sono la prova più eclatante. Quindi quella rivoluzione, quell'ondata di videogiochi con grafica da cinema e gestione di pianeti in tempo reale, non c'è mai stata, tuttavia adesso, nel 2008, si sta affacciando per pc qualcosa di molto simile.

I dual/quad core, le schede grafiche come la NVidia 8800 e le schede per la gestione della fisica come la PhysX di Ageia, stanno aprendo la strada a tutta una serie di videogiochi che implementano quel salto di qualità al quale ci avevano abituato le promesse non mantenute del passato.

Super Ball Smasher

Rilasciato finalmente in versione completa questo clone di Pang che ho programmato qualche tempo fa. Potrete usufruire di 50 stages distribuiti in 5 livelli di gioco con ambientazioni a tema e musiche suggestive create appositamente per immergere il giocatore nel clima del livello senza degenerare nel fastidio della ripetitività.

Il concept, la grafica e la musica sono totalmente originali e studiati per offrire una interessante variazione al solito e monotono schema dei cloni di pang, non rischiando di appesantire il gioco ma rendendolo al contrario più divertente e longevo. Il boss di fine gioco cerca oltremodo di ripagare le aspettative del giocatore, proiettandolo in una sfida finale non eccessivamente complessa, ma neanche troppo banale, con lo scopo di concretizzare in una vittoria finale il lungo cammino affrontato attraverso i 5 livelli di gioco. L'intero progetto è stato creato in poco tempo e usando software opensource. L'unica versione disponibile è momentaneamente per pc/windows, che potete scaricare cliccando direttamente qui (download). Buon divertimento.
