@cmuratori In yesterday's @handmade_hero, shouldn't the perspective ratio be p'/p = d/(c - p + d)? Full length of bottom is (Cz - Pz) + d
@JonathanEvraire @handmade_hero But they both are? p is p_z from the camera, p' is d from the camera. Right?

@cmuratori On the graph p/screen was d from eye in Z, Pz is p' Z coord and Cz is the camera's Z coord. So p' is (Cz - Pz) + d from eye, no? -
@cmuratori But maybe I'm just confused by the relationship between Cz and d? - Show replies
