gleScrew

Draws screw-type shapes.

Signature

gleScrew( int( ncp ) , gleDouble[][2]( contour ) , gleDouble[][2]( cont_normal ) , gleDouble[3]( up ) , gleDouble( startz ) , gleDouble( endz ) , gleDouble( twist ) )-> void
gleScrew( contour , cont_normal , up , startz , endz , twist ) 
gleScrew( c_int(ncp), arrays.GLdoubleArray(contour), arrays.GLdoubleArray(cont_normal), arrays.GLdoubleArray(up), gleDouble(startz), gleDouble(endz), gleDouble(twist) ) -> None

Parameters

VariablesDescription
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.
