Kyvos The Iphone Puzzle Game

After 2 years I finally publish a new iphone app .Its called kyvos which means cube in Greek.Kyvos is a free 3d puzzle board game where the purpose is to move your cubes to the level exit .The game has 50 levels for the single player mode and a multi-player mode where the game becomes a board turn-based game
where 2 players can compete on the same device.In the multi-player the player who has the higher number of exiting cubes wins.
Download it here its free !

I publish a video tutorial for the single player which can be viewed here

Light Pre Pass Shader

I created a light pre pass shader in rendermonkey.The shader uses one render target RGBA (8:8:8:8) for normals (polar coordinates xy) and depth (zw) and one render target for the light pass (no extra specular term) .The shader is availiable at the following link

Deferred Rendering

I created a small project in render monkey(v 1.8) for a deferred rendering shader using hlsl shader model 3.
It supports normal mapping by saving normals using polar coordinates (not so fast :)) and depth in an R32F format.I put the code in the following link

The plan is to enrich it with ssao,hdr and other effects in order to become a small pipeline.The project currently not supports light volumes but is the next step.

My iphone app is down :( but I'll become a father :)

I removed my iphone app 'ipostit' from the appstore cause the name caused a copyright violation; a sad way to start the year. I' ll rename my app hoping to find a good copyright free name... tough times for small software utilities like mine. Anyone who bought the application and reads this blog, a big thanks to u. I am thinking to give it free under a different name of-course

In less than a month I'll become a father and I am more than excited; heavy word: FATHER !!!:).
I am expecting a cute girl (doctor told us about 4 kgr, God damn is big!!) therefore the women of my life get increased by one .Hope she won't be a programmer (and if she does then be a rich one for gods sake ). A hairdresser makes more money than an engineer in Greece (and especially the cute ones ;) ). Anyway, judging by the rate I post to this blog the next time I' ll be
a family guy .

p.s. Not to forget: Have a happy new year 2010!

Iphone 3d Engine

I found some time to dedicate to my small 3d engine on the iphone.
The graphics engine is based on oolong engine although I do not use the VFP math library.
So far it supports md5 models and animation (doom3 format),proc scene files (portal visibility)
custom material files (for color or textures) and frustum culling .So far I have a simple first person camera able to move back- forward and strafe left -right by sliding on the screen.The engine is slow on the device because of the animation code which is a non- optimized (thinking to start learning the vfp part ;)) .
For start I will remove the weight normal calculation code which has no reason to exists for now cause I do not use any lights
