PRIM_TYPE_BOX

Description

Constant: integer PRIM_TYPE_BOX = 0;

The integer constant PRIM_TYPE_BOX has the value 0

PRIM_TYPE_BOX is a parameter of PRIM_TYPE used to make prim into a box and to change specific properties that define the shape of that box.

PRIM_TYPE

[ PRIM_TYPE, PRIM_TYPE_BOX, integer hole_shape, vector cut, float hollow, vector twist, vector top_size, vector top_shear ]

• integer	hole_shape	–	PRIM_HOLE_* flag
• vector	cut	–	x and y range from 0.0 to 1.0, x must be at least 0.05 smaller than y (z is ignored)
• float	hollow	–	ranges from 0.0 (solid) to 0.95 (maximum hollowed)
• vector	twist	–	ranges from -1.0 (-180 degree in the edit window) to 1.0 (+180 degree in the edit window) for both x and y (z is ignored)
• vector	top_size	–	ranges from 0.0 to 1.0 to 2.0 for both x and y (z is ignored)!
• vector	top_shear	–	ranges from -0.5 to 0.5 for both x and y (z is ignored)

hole_shape Flags		Shape	hole_shape Flags		Shape
PRIM_HOLE_DEFAULT	0x00	Default	PRIM_HOLE_SQUARE	0x20	Square
PRIM_HOLE_CIRCLE	0x10	Circle	PRIM_HOLE_TRIANGLE	0x30	Triangle

PRIM_TYPE_LEGACY

[ 1, PRIM_TYPE_BOX, vector cut, float hollow, float twist, vector top_size, vector top_shear ]

• vector	cut	–	x and y range from 0.0 to 1.0, x must be at least 0.05 smaller than y (z is ignored)
• float	hollow	–	ranges from 0.0 (solid) to 0.95 (maximum hollowed)
• float	twist	–	ranges from -0.5 (-180 degree in the edit window) to 0.5 (+180 degree in the edit window)
• vector	top_size	–	ranges from 0.0 to 1.0 for both x and y (z is ignored)!
• vector	top_shear	–	ranges from -0.5 to 0.5 for both x and y (z is ignored)

This is the old PRIM_TYPE format for boxes (PRIM_TYPE used to be 1 instead of 9). Use the new format unless you are maintaining old code.

Caveats

• top_size and client values are different, conversion is required. This simple equation can be used: answer = 1.0 - value.

	Range	Top Tapered	No Tapering	Bottom Tapered
Client	[-1, 1]	1.0	0.0	-1.0
PRIM_TYPE	[0, 2]	0.0	1.0	2.0
LEGACY[1]	[0, 1]	0.0	1.0	NA
