Returns an initialized FXGLSphere instance.

One option is to initialize the sphere with a specified origin and radius:

aSphere = FXGLSphere.new(x, y, z, r)

If left unspecified, the radius (r) defaults to 1.0.

Another option is to initialize the sphere with a specified origin, radius and material:

aSphere = FXGLSphere.new(x, y, z, r, material)

where the material is an FXMaterial instance.

Calls superclass method Fox::FXGLShape::new

Public Instance Methods

drawshape (viewer)

Source

# File lib/fox16/glshapes.rb, line 447
def drawshape(viewer)
  quad = GLU.NewQuadric()
  GLU.QuadricDrawStyle(quad, GLU::FILL)
  GLU.Sphere(quad, @radius, @slices, @stacks)
  GLU.DeleteQuadric(quad)
end

Draw this sphere into viewer (an FXGLViewer instance).
