What is ray tracing?

I wanted to hear his definition

Wow, that's definatly the GPU that's causing it to be that slow.

No way, my X300 is gets 15-16

15/16 with 31 on occasion.

Imagine a 3D world that you want to see through the screen. The screen can be thought of a window, with you sitting behind it.

With ray tracing you imagine a focus point where your eyes are (only one focus point, unless you want stereo-vision).
At it's most basic, you fire rays from this focus point through all pixels on the screen/window. You then test for collisions etc, and if you want you can do reflections and refractions. At the end of this you get a colour for the ray, and that's what you colour the pixel.

Do this for all pixels and you've got your image.

To get a better picture you can fire more rays through each pixel, re-use the colours for corners of pixels etc. I'm concentrating on optomisations to speed up the process, rather than improve the image.

And that supports what i said, you've got a fast graphics card and it takes only 15/16 milliseconds to render a frame (which is as fast as the program will let you go).

That could be for a number of reasons, since i don't do any error checking at the moment.

Did you put the exe in the same folder as the earth.bmp file?
Do you have DX9 installed?
What's your graphics card?

yes
yes
implanted in motherboard graphics thingy, no acceleration and (probably) no onboard ram.

 

[SLH]

That's probably the problem then. I guess it doesn't support non-square texture sizes or something.

awww... i need to get my computer fixed.

 

[ZeeM]

maybe you've got too much memory being eaten by random apps in background ?

nope, thats definitely not the case ;(

 

[SLH]

How is it real time if it's measured in time per frame


EDIT: I'm getting 70-100...

It's more realtime than other ray tracers, which can take hours per frame.

 

[NonStopableForce]

Well i tryed it again today, and some reason my pc was acting better and i got liek 104, and i opened FRAPS and got 9 fps. : p

[SLH]

Lol.

I've since done some tweaking, and it runs at the max speed on my computer, which is a 1.5ghz geforce 3 card, so it's going nice and fast now!
