## Description

CastingStage is a simple raytracing engine made using Cocoa.

It intends to be lean and mean, easy to use, and to showcase

several Mac OS X technologies, such as bindings, CoreData,

Grand Central Dispatch, and so on.

You can view some Screenshots or download the application

(requires Mac OS 10.6 for now, Leopard support coming soon).

## Current features

* Basic primitives handling (spheres and planes)

* Reflection and refraction

* Point and area lights

* Depth-of-field effect

* Quick preview of scenes

* Anti-aliasing

* Document-based application: save and open scenes

* Export rendering in various formats

* Demonstration scenes included 

## Future features

* Use of CoreData with Undo support

* Multi-threading that doesn't leak memory

* Image resizing 

## Why 10.6 only ?

Because this project began as a way to experiment new Snow Leopard technologies,

like Grand Central Dispatch and C-blocks for the multi-threading.

I could backport the GCD code, using NSOperation rather that C-blocks, which

would make it work under Mac OS 10.5, and still retains the benefits of GCD

under 10.6 ; this is probably what will happen as soon as I'll find the time to do it.
