Converting coordinates to Screen position, without matrix?

[shadowvzs]

how can i convert coodinates to display position without vjass and matrix?

i guess this is the angle if camera not rotated but idk how to get the position (like in dgui)

local real CamTX = GetCameraTargetPositionX()
local real CamTY = GetCameraTargetPositionY()
local real CamTZ = GetCameraTargetPositionZ()
local real CamSX = GetCameraEyePositionX()
local real CamSY = GetCameraEyePositionY()
local real CamSZ = GetCameraEyePositionZ()
local real ang = bj_RADTODEG * Atan2(CamTZ - CamSZ, CamTY - CamSY)

Yes, that's the "angle of attack". You can use that if camera is rotated :

local real ang = bj_RADTODEG * Atan2(CamTZ - CamSZ, SquareRoot((CamTY - CamSY)*(CamTY - CamSY)+(CamTX - CamSX)*(CamTX - CamSX)))

However, I don't get the question. Position of what?

Camera.

local point p = Location(x,y)
should help

positioning objects on screen, like in dgui, dynamic graphical user interface, so positioning objects (unit) to a fixed position, like hero icons in top left corner, so something like this screenshots

and i know about i need point for get the terrain height but that never was problem,

Maybe you should use matricies and vectors? Seeing how that is what the GPU does to make the image it is probably a very good idea.

pls read the 1st post, i told i cant use the matrix because i dont want it in vjass, i want try in jass but first of all i want try to understand how to calculate the vectors and other part, because seeing the code with structs done say nothing to me

 

[Dr Super Good]

What does vjass have to do with matricies and vectors? I am refering to the mathematical opperations.

Solve them by hand (or with the help of tools like mathematica) and you will get an equation that you can produce in JASS that will compute what you are after.

because idk that formulas and only place where they was wrote it is in vjass structs
