Creates a VRML cone.
Center
A 3-element array specifying the true center of the cone object. (Default: 0, 0, 0)Height
Specifies the cone height (Default: 2.0)Orientation
A 3-element array specifying the orientation of the cone (in the direction of the apex). (Default: cone axis orientation along y, with the apex at +y)Radius
Specifies the radius of the cone base from the y-axis. (Default: 1.0)Transform
A 4-by-4 matrix containing the transformation to be applied to the cone object; similar to !P.T.
AmbientColor
A 3-element array of RGB color with each element ranging between 0 to 255. If the value is scalar, then the color is interpreted as grayscale.DiffuseColor
A 3-element array of RGB color with each element ranging between 0 to 255. If the value is scalar, then the color is interpreted as grayscale.EmissiveColor
A 3-element array of RGB color with each element ranging between 0 to 255. If the value is scalar, then the color is interpreted as grayscale.Shininess
Scalar shininess factor, in the range from 0 to 255.SpecularColor
A 3-element array of RGB color with each element ranging between 0 and 255. If the value is scalar, then the color is interpreted as grayscale.Texture_Image
A texture image to apply to the object. The image is wrapped completely around the object. The texture image values and transparency values lie in the range of 0 to 255.There are four options:
Grayscale image(2, w, h)
Grayscale in (0, *, *) plus transparency in (1, *, *)(3, w, h)
True color image (red, green, blue)(4, w, h)
True color plus transparency in (3, *, *)
Scalar transparency factor, in the range of 0 to 255.
