Dimensional Data
This is more confusing than I expected!
From ai_hull.cpp I got this vector data, which i have tried to interpret into box dimensions. The first pair of coords seem likely to describe the collision hull, but the second set of coords ... ? :
Ground Nav Collision Hull vectors ? vectors Hull dimensions ? dimesnsions * Tiny_Hull (-12,-12, 0), (12, 12, 24), (-12,-12, 0), (12, 12, 24) = 24 x 24 x 24 &/ 24 x 24 x 24 * Human_Hull (-13,-13, 0), (13, 13, 72), ( -8, -8, 0), ( 8, 8, 72) = 26 x 26 x 72 &/ 16 x 16 x 72 * Wide_Human_Hull (-15,-15, 0), (15, 15, 72), (-10,-10, 0), (10, 10, 72) = 30 x 30 x 72 &/ 20 x 20 x 72 * Medium_Hull (-16,-16, 0), (16, 16, 64), ( -8, -8, 0), ( 8, 8, 64) = 32 x 32 x 64 &/ 16 x 16 x 64 * Medium_Tall_Hull (-18,-18, 0), (18, 18, 100), (-12,-12, 0), (12, 12, 100) = 36 x 36 x 100 &/ 24 x 24 x 100 * Wide_Short_Hull (-35,-35, 0), (35, 35, 32), (-20,-20, 0), (20, 20, 32) = 70 x 70 x 32 &/ 40 x 40 x 32 * Large_Hull (-40,-40, 0), (40, 40, 100), (-40,-40, 0), (40, 40, 100) = 80 x 80 x 100 &/ 80 x 80 x 100 Air Nav * Tiny_Centered_Hull ( -8, -8, -4), ( 8, 8, 4), ( -8, -8, -4), ( 8, 8, 4) = 16 x 16 x 8 &/ 16 x 16 x 8 * Small_Centered_Hull (-20,-20,-20), (20, 20, 20), (-12,-12,-12), (12, 12, 12) = 40 x 40 x 40 &/ 24 x 24 x 24 * Large_Centered_Hull (-38,-38,-38), (38, 38, 38), (-30,-30,-30), (30, 30, 30) = 76 x 76 x 76 &/ 60 x 60 x 60 note: all NPC Hulls have a square footprint with the origin at the centre = NPC's centre of horizontal rotation. (why not use a cylinder?) note: Ground nav NPC Hulls tower above the origin, whereas Air-nav (_Centered_Hull) hull is half above and half below its origin.
Notice also that the min pathway for human_hull is 30 wide by 73 high, so there's some factor other than hull size involved. Even more bizarrely, npc_combine.cpp uses the human_hull, but it's min pathway is wider than other humans tested; 32 wide by 73 high.
