Provided herein are compositions for applying a reference marker pattern or grid to the surface of an object to be imaged three-dimensionally. These compositions can be quick drying for ease of use. Methods of use of the compositions are also provided as well as devices and kits for the application of the compositions. 1. A device for the application of a contrast pattern to a surface of an object to be imaged in three dimensions , comprising:a canister;a nozzle coupled to the canister; anda solution contained within the canister and deployable from the canister by way of the nozzle, the solution comprising a plurality of particles adapted to act as reference markers for an imaging device; a propellant; an intermediary solvent soluble in the propellant; and a polymeric bonder adapted to bond the plurality of particles to the surface of the object, the polymeric bonder being soluble in the intermediary solvent.2. The device of claim 1 , wherein each particle is either a first color or a second color.3. The device of claim 1 , wherein each of the plurality of particles is generally spherical.4. The device of claim 1 , wherein the solution is adapted to dry under ambient conditions within about ten seconds after exiting the nozzle.5. A solution for the application of a contrast pattern to a surface of an object to be imaged in three dimensions claim 1 , comprising:a plurality of particles suspended in the solution;a propellant;an intermediary solvent soluble in the propellant; anda polymeric bonder adapted to bond the plurality of particles to the surface of the object, the polymeric bonder being soluble in the intermediary solvent.6. The solution of claim 5 , wherein the plurality of particles consists of titanium dioxide spherical particles and vitreous carbon spherical particles.7. The solution of claim 5 , wherein the propellant is a hydrofluorocarbon (HFC).8. The solution of claim 7 , wherein the propellant is selected from the group consisting of 1 claim 7 ,1 ...
