i don't know nothing about programming so maybe you guys can take a look at this.

one thing i noted that seem very important is this

Quote:

don't cast a ray through the whole scene, but instead limit the length of the ray to |B-A|.

It's almost the same thing as SimReality's raycasting engine.

Not quite. This is using raycasting for doing collision checks and picking; not rendering it seems. So it's the same basic technique of shooting rays into a scene, but it has a different purpose.

I already wrote a raycaster for the Zune: http://www.zuneboards.com/forums/dev...x-release.html. Might need to be optimized, but we don't need to find someone to make one. It's done.

i understand that but my point is maybe looking at others would help you figure out how to make it faster. it always go back to seeing that pototo chase thing. i don't know. i'm not ashamed at being a noob with c# but i know that we are forever learning. i really dont have the patience to even get started. to be honest but i'll start following a book from a-z and see what happens.

It's not like he needs someone to tell him how to Optimize it

If you read the raycastingX thread that he posted up, it said he's spending time working on dreambuildplay project.
