Doubt about screen to world space node

[Sandy]

Coordinate transformation is very difficult and confusing.

It is not “Screen to World” information but “World to Screen” information, but important things are written here.

WorldToScreenCoord? - draw debug lines with 2D API

Hello, DebugDraw class uses a plane to draw a line: it’s creepy ! I would draw a line with 2D API. But I don’t understand the “World To Screen Coords” logic Node : override function get(from:Int):Dynamic { var v1:Vec4 = inputs[0].get(); if (v1 == null) return null; var cam = iron.Scene.active.camera; v.setFrom(v1); v.applyproj(cam.V); v.applyproj(cam.P); return v; } I found a topic about “Screen to World” and so I try this : public function WorldToScreen(loc:Vec4):V…

This information is useful because the “Screen to World” conversion is the opposite of the “World to Screen” conversion, but it doesn’t seem to work well just by taking this into account.
