(Screen 2D) -> (3D Points with specified distance) - iPLEOMAX - 13.04.2012
Trigonometry experts, how would I do that?
What I have:
- X and Y Position in the screen.
- Width x Height, Resolution of screen in pixels (to roughly calculate player's field of view)
What I want:
- X,Y,Z in 3D Space with a distance specified by myself.
The function should look like this:
pawn Код:
ScreenToWorld(Float:ScreenX, Float:ScreenY, Float:Distance, &Float:X, &Float:Y, &Float:Z)
pawn Код:
GetScreenResolution(playerid, &Float:Width, &Float:Height);

Would something like this?
pawn Код:
ScreenToWorld(ScreenX, ScreenY, 30, &Float:X, &Float:Y, &Float:Z)

Yes but in the image, the XYZ is in wrong place, it's supposed to be behind the screen xy.

I'm really interessted in something like this, but idk how to realize that. Somebody already found a solution to transform Positions between 2D and 3D?

There a several complications to this. The coordinates of the player's camera updates slowly and
the world's objects (including terrain) are not calculated by the server, so you'll need a height map which will make it even more inaccurate

i think thats unimportant the most hard stuff is the convertion

The thread is one year old though, the OP might solved it.
