Why Coordinate Spaces are IMPORTANT in Game Development

[@YupesRino]

Keep going with this series, can't state how important the fundamentals are. Fundamentals give freedom for the dev and allow one to escape the so dreaded "tutorial hell".

Thanks, I needed to hear this.

I would like a video of transforming vectors. I often follow Unity or Unreal tutorials. But then come across Unreal nodes such as TexCoord[0] ( which i believe is just UV) and TransformVector-'TangentSpace to WorldSpace' or CameraSpace to LocalSpace, and my work comes to a complete stop. Finding a technical description of them is hard. Finding them in UE5 and then Godot is harder. Often there are multiple names for the same spaces, with inverted or mirrors coordinates.

Hey Robin, I have touched about transforming vectors briefly in Matrix video and yup TexCoord is indeed UV. Lastly the result of a transformed vector might differ from engine to engine depending on how their coordinate space is setup, Unreal follows Z up like Blender while Godot and Unity is Y up environments. Then it also depends on how they represent matrices internally (column major and row major).

I'm gonna have a look at your matrix video tomorrow, I have missed that one. Saw that you had a good outliner videos as well. Godot has this nice conversion list with glsl to Godot. Would be convenient if they had something similar with Unreal to Godot as well.
