3d

Hi!

i've asked this before:

how do i draw a 3d dot on a 2d screen?

i know camera position and angles and i know the dots position.

how do i calc where this dot should be plotted?

I asked for this in other 3D-expert-places and the simplest way to do this is to use these equations:

Code:

---

Xscreen = (X3d * D) / (Z3d + D) + Xcenter
Yscreen = (Y3d  * D) /( Z3d + D) + Ycenter

---

Where D, choosen by you, is the distance between the center of the projection and the viewer.

Xcenter and YCenter is the center of the screen, where Xcenter is 160 and Ycenter is 100 if you are 320*200 resolution, etc.

Bye

P.S.: I don't work with 3D, I just had this infos :)

thanks, but i've allready tried this. the problem here is that i dont have the camera angles in the equations...
