Abstract: The implementation of reflective material is an important performance to judge whether the 3DS MAX virtual reality is true. In this thesis, provides a specific solution for the implementation of reflective material in 3DS MAX by discussing the reflection pinup picture in material characteristic.

The wider world have different types of objects, each object through its own texture, surface texture reflects the characteristics of different materials. In the virtual reality created by using three-dimensional software showed a different material types, which provide viewers the most intuitive visual experience .3 DS MAX is PC-based three-dimensional design in most major design software, 3DS MAX powerful, easy operation, in the production of virtual reality has been widely used.

1 Introduction material
3DS MAX material is a more complex realization of the production process, which in real life by imitating the surface of the light reflection and communication, virtual reality, material properties .3 DS MAX in the different parameters and can create different textures material texture, reflective effect and object texture to the performance of real-life objects. reflective material in many of our daily life, see, such as: mirrors, steel, glass, water, etc., in 3DS MAX, the reflective material can often be made reflect the reality of virtual reality.

3DS MAX standard material editor can be divided into four pArts: menu bar, sample windows, buttons and parameter adjustment of work area. Where the parameters adjustment of regional and can be divided into 6 pArts, namely: Shader Basic Parameters (Shader basic parameters), Blinn Basic Parameters (effect of basic parameters), Extended Parameters (extended parameter), Super Sampling (super sampling), Maps (map-channel), Dynamics Properties (kinetic parameters).

2 reflective material
Reflective material is a map 3DS MAX mode, the material in 3DS MAX Maps (map access) Reflection under the reflection map. Reflection map is an important texture mapping, the production has a non-reflective material alternative position in the 3DS MAX map in the Reflection Reflection There are several ways to make the following reflective material.

2.1 Bitmap textures reflective material
Textures reflective material is the most basic method of making reflective material, refers to a bitmap is specified as a reflection map, is mainly used in static images, the site is one of the most efficient way of mapping.

The use of textures reflective material, first select the material 3DS MAX command panel, in the adjusted basis of the basic properties of materials (eg, steel need to adjust the Shader Basic Parameters of the material under the type of Metal, Blinn Basic Parameters of the Diffuse effects of the transition of basic parameters Color, Specular Level of high brightness, Glossiness gloss), and then select the material command panel Maps (map access) Reflection under the reflection map, reflection map in the back of None (map selection) in the selection process Bitmap (Bit Figure), and then the Computer's local disk, select the appropriate picture production to be in the material (see Figure 1, Map # 51 for the material after the material appears to join the bitmap effect). Reflection map Reflection Amount (parameter values) can be from 0 to 100, when the Amount is 0 when the reflectivity minimum, when the Amount to 100, reflecting the highest.

Mapping method to make reflective material is a Computer in the calculating process of computing the fastest, that is rendering the most efficient way, but the effect is not real, so in the dynamic image or larger picture scenes generally do not apply.

Reflect / Refract (reflection / refraction map) reflective material production is to produce the surface of the object of reflection or refraction effects. Materials command panel, select the Maps (map access), select Reflection reflection map, reflection map in the back of None (map selection) in the selection process Reflect / Refract (reflection / refraction map), the set is specified as produce reflections Reflect reflection, refraction designated as Refract refraction effects arising .Reflect / Refract (reflection / refraction map) is axis points from the object to the six directions around the photo shoot six, and then to spherical map attached to the surface the way, this is called 6-sided map, the system automatically. In light of our daily lives will be unlimited reflection or refraction occurs in 3DS MAX the number of refraction or reflection in the freedom to decide, in the Render (rendering), Control Panel, Auto Reflect / Refract Maps item Rendering Iterations (rendering repetitions) the value of the maximum can be rendered in the rendering 10 times, while the rendering time will increase 10 times.

2.3 Flat Mirror (mirror reflection) reflective material
3DS MAX specular map is a special type of texture produced a mirror effect. In the choice of material 3DS MAX command panel, select the material command panel Maps (map access), select Reflection reflection map, paste the reflector Figure subsequent None (map selection) in the selection procedure Flat Mirror (mirror reflection). Reflection map Reflection Amount (parameter value) as can be from 0 to 100, when the Amount is 0 when the reflectivity minimum, when the Amount is 100, the highest reflection.

Flat Mirror (mirror reflection) dedicated to a group of coplanar surface of the mirror reflection effect, Flat Mirror (mirror reflection) is the Reflect / Refract (reflection / refraction map) added, Reflect / Refract (reflection / refraction map ) can not be calculated on common side surface, Flat Mirror (mirror reflection) is only acting on the mirror effect, is not before 3DS MAX R2 Raytrace (Ray Tracing), the main method of mirror effect.

2.4 Raytrace (Ray Tracing) reflective material
Raytrace (Ray Tracing) is a virtual reality way to map the formation of reflections, the results closest to the real effect, and most take time to map a way, like the other two selection methods, but a reflection map in the back of Reflection The None (map selection) in the selection process Raytrace (Ray Tracing). Raytrace (ray tracing) can be completely reflected and refracted light, the effect of bringing realistic rendering is also the longest, but by exclusion of the scene optimization can also be used Attenuation (fading), add more realistic effects, attenuation is the attenuation of light produced can be controlled, and thus have different objects with different strength of distance refraction and reflection.

3 Refraction Refraction map
Refraction Refraction map is mainly used for glass, water and other objects, the performance of virtual reality, is to produce a surface reflection effects on the surrounding objects, the command panel, select the material Maps (map-channel) in the reflection map Here is Refraction Reflection refraction map, it reflect different, Refraction Refraction map the performance of transparent or translucent objects through the saw. In the setting of glass, water and some other transparent and translucent objects often set together. It is worth mentioning is the refraction map of the Thin Wall Refraction (thin wall refraction map) mainly some of the thin transparent and translucent objects, the refraction effects, such as: through the glass of water or straw; through the spectacles of books, etc., able to show realistic effects, and in the production of the transparent or translucent reflective material often used.

4 Summary
3DS MAX reflective material is more material in the performance of one material, through its performance in the virtual reality with a reflective objects, such as water, glass, wood, tile and more. Want to make a beautiful reflective material effect also need to be diligent in practicing the above method.
