CYLINDER Function

Defines a cylindrical object that can be used by the RENDER function.

result = CYLINDER( )

None.

result A structure that defines a cylinder object.

Color A 256-element double-precision floating-point vector containing the color (intensity) coefficients of the object. (Default: Color(*)=1.0)

Decal A 2D array of bytes whose elements correspond to indices into the arrays of material properties.

Kamb A 256-element double-precision floating-point vector containing the ambient (flat shaded) coefficients. (Default: Kamb(*)=0.0)

Kdiff A 256-element double-precision floating-point vector containing the diffuse reflectance coefficients. (Default: Kdiff(*)=1.0)

Ktran A 256-element double-precision floating-point vector containing the specular transmission coefficients. (Default: Ktran(*)=0.0)

Transform A 4-by-4 double-precision floating-point array containing the local transformation matrix whose default is the identity matrix.

A CYLINDER is used by the RENDER function to render cylindrical objects, such as for molecular modeling (symbolizing bonds), or for generating axes and 3D lines. It is defined as having a radius of 0.5 and being centered at the origin with a height of 0.5 in the +z direction and 0.5 in the -z direction.

To change the dimensions and orientation of a CYLINDER, use the Transform keyword.
