i had no idea how astra did all of the tracking & vfx for the shot
so i made it create a blog post explaining it and it's pretty cool
it used COLMAP for 3D tracking, then imported that into blender & used the real table as a texture for reflections

this VFX scene was entirely tracked / modeled / lighted / composited by GPT-6 Astra 
all I gave it was a 4K 60FPS recording from my phone
the mug is a lie
