Problem in Generating 3D surface

hi all,
i am facing some problem in generating a 3D hyperbolic surface. i have generated the points. can u suggest me some method to create a mesh structure and map a single texture throughout the surface. Actually if i connect the points and form different QUADS to create mesh structure and when i map the texture it maps on each QUADS but i want to map single texture on the whole surface.
Thanks anyway,
