Hello.
Guys, help me please calculate position of point D.
I know position of A, B, C and DE length.
In 2D space it’s quite simple, but I cant do it in 3D.
Hello.
Guys, help me please calculate position of point D.

Do you know the position of E?
No, only positions of triangle.
A is my camera, B is ground, and C is point on ground from raycast.
Do you have link to do it in 2D?
tg(CBA) = AB/BC = (A.y-B.y)/(C.x-B.x);
Then ED is 2;
EC = (C.x-B.x) * ED ) / (A.y - B.y)
BE = BC - EC;
D = (B + BC, ED);
Okay, thanks buddy from Discord, the formula is:
F/AB * (A-C) +C
Where F is your factor. 2 in my case.
