NAME¶

gleScrew - Draws screw-type shapes.

SYNTAX¶

void gleScrew (int ncp,


               gleDouble contour[][2],


               gleDouble cont_normal[][2],


               gleDouble up[3],
	       gleDouble startz,
	       gleDouble endz,
	       gleDouble twist);

ARGUMENTS¶

ncp

number of contour points

contour

2D contour

cont_normal

2D contour normals

up

up vector for contour

startx

start of segment

endz

end of segment

twist

number of rotations

DESCRIPTION¶

Draws screw-type shapes. Takes a contour, and extrudes it along the z-axis, from a start z value of startz to an end z-value of endz. During the extrusion, it will spin the contour along the contour origin by twist degrees.
