Center
A 3-element array specifying the center of the sphere object. (Default: 0, 0, 0)Radius
Specifies the sphere radius from the center. (Default: 1.0)Transform
A 4-by-4 matrix containing the transformation to be applied to the object.
Creates a sphere in a VRML world.
Center
A 3-element array specifying the center of the sphere object. (Default: 0, 0, 0)Radius
Specifies the sphere radius from the center. (Default: 1.0)Transform
A 4-by-4 matrix containing the transformation to be applied to the object.
AmbientColor
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.DiffuseColor
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.EmissiveColor
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.Shininess
A scalar shininess factor, in the range of 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 texture image is wrapped completely around object (CLAMPed). Image values and transparencies lie in 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, *, *)
A scalar transparency factor, in the range of 0 to 255.
