In entire disclosure and claims, term can have outside the implication being expressly recited within a context The delicate implication for implying or implying.Similarly, as used herein phrase " in one embodiment " not necessarily represents identical Embodiment, and not necessarily represent different embodiments in phrase used herein " in another embodiment ".Such as, it is desirable to The theme of protection includes the combination of all or part of exemplary embodiment.Generally, term can be at least in part from context In usage understand.For example, it is as used herein such as " and ", the term of "or" or "and/or" can include can be with Based in part on the various implications of the context using these terms.Generally, if "or" be used for linked list (such as A, B or C), it is intended to represent A, B and the C used here with inclusive meaning, and A, B or the C used here with exclusiveness meaning. In addition, the term " one or more " used here based in part on context can be used for describing appointing in odd number meaning What feature, structure or feature, or can be used for describing the combination of feature on plural references, structure or feature.Similarly, extremely Partially based on context, it is also understood that such as " one (a, an) " or "the" etc term passes on odd number usage or biography Up to plural usage.In addition, term "based" can be understood as being not necessarily intended to pass on one group of exclusive factor, and can substitute Ground allows the additive factor being not necessarily expressly recited be present based in part on context again.
The two dimension printing of data on paper is converted into for from the picture number for being fed to computer by the improvement of printing technique According to the additive process of printing threedimensional model.The three-dimensional printer used at present is (such as one micro- every time by the way that printed material is layered Rice) build threedimensional model.The model created by 3 D-printing can include firm internal structure, and this is with traditional dies It is impossible.Using different materials (such as the plastics of different colours, metal or resin) mould can be built via 3 D-printing Type.Although can use a variety of colors and material for the usage of 3 D-printing, current three-dimensional printing technology is only limitted to Major print surface shows the model of simple reflex rate, such as lambert (Lambertian) surface, its can not express by The true reflex behavior of the practical object of modeling.
Although three-dimensional printer can be modeled to the detailed construction of Eiffel Tower, it can not catch in a model Obtain the true reflection characteristic for the metal for forming actual Eiffel Tower.What reflection characteristic can not correctly be captured by three-dimensional printer answers Another example of miscellaneous structure is the face of people's (or other species).The complex set that the face of live body includes tone and light and shade merge with Complicated mode reflected light, can not also be captured even with best high-resolution three-dimension (3D) printer.For example, resolution ratio is smart What the thin three-dimensional printer up to 16-30 microns was currently available.Therefore, when printing facial, such as hair and hair can be printed The feature in hole.However, the model printed even with the three-dimensional printer of optimum resolution is although accurately replicate object Structure, it can not seem true.Because the reflective character of object determines that these factors are not by the sets of factors of complexity Only include the physical property (such as microcosmic surface details and color) of object, and the chemical property including object in itself.If There is no improvement set forth herein, then 3D printing model can not capture exactly object how with light interaction as details.
The multiple parasitic reflection for currently existing to capture and record in detail object (such as biological face or skin) is special The technology of property.The light stage that will be described in detail further below is an example.Similarly, also exist and set by calculating The technology of the standby reflection characteristic for producing object.For example, produced using the lighting engineering again based on image under any lighting condition The photorealism of object.The application of this technology, which is especially included in the scene of film, inserts character.
Using the device of such as dome-shaped light stage or portable lamp optical stage etc, for by irradiating from different directions Object captures the reflectivity data of object.The multiple images of object are captured, wherein the object in each image is come from and it The illumination in the different direction of his image is bright.Therefore, can be directed to light of each pixel capture from all directions intensity, this It can be rebuild pair by using mathematical modeling under any other lighting condition not captured by the device of such as light stage etc The image of elephant.This can be by being fitted to the albedo measurement obtained from the light stage for subject surface by Reflectivity Model Value is realized.In addition it is possible to use such as model of Lambertian, Phong or Ward model etc is extrapolated for specific One group of reflectance measurement that direction obtains, to obtain the intensity for the incidence angle being not included in measurement group.
The interaction of each surface and light can be described with bidirectional reflectance distribution function (BRDF).Generally, light is anti- The degree for penetrating (or transmission) depends on observer and relative to surface normal and the optical position of tangent line.Due to BRDF instructions just How to be reflected, therefore it must capture the visual angle of reflected light and light pauper character.Therefore, BRDF is at light interaction point It is the function in incident (light) direction and outgoing (visual angle) direction relative to local orientation.However, beaten there presently does not exist 3D is assigned Stamp type is with the technology of various reflective characters (such as those characteristics expressed by the BRDF of subject surface).
Embodiment disclosed herein can provide the reflective character of object for the model of object so that model is also with similar In the mode reflected light of object, so as to appear more like practical object compared with the model printed from conventional 3D printer.More Body, the mould of object is applied to embodiment described herein the light interaction property for being able to record object and by these characteristics Type.This assigns model with the reflective character of object, so that model seems essentially identical with object.In one embodiment In, can be by 3D printer printer model so that the depth information of subject surface is trapped in the data of 3D printer reception, Model of the data transfer to printing.In one embodiment, the reflectivity data captured can via what is be described in detail herein The holographic technique illuminated again is sent to 3D printing model.The 3D of depth and both light interaction attributes including practical object Printer model will seem truer than the model obtained from 3D printer.
In certain embodiments, the reflectivity data for object can illuminate holography again as be attached at 3D printing model Figure is printed.Holographic be it is a kind of be used for record object illumination information and afterwards in the case of no object again Show it so as to produce the technology for the illusion that object be present.In order to generate the hologram of object, with such as coherent source (such as laser) Or the light source irradiation object of spectral filtering light source etc.Combined from the light of object reflection with reference beam, the reference beam can be with It is the direct light from light source.The pattern as caused by the interference of the reflected beams and reference beam is trapped in such as photo etc In recording medium.However, by using simple focusedimage bag of the recording figure forming that holographic captures than such as photo etc Containing more information.This makes it possible to the 3-D view of reproduced objects, causes the illusion that object be present.
