The Basic Technology of the 3D Lighting
post time:2013-01-30

Taking from the 3DMax basic technology of lighting, maybe you rarely not think of how the light source working in the real world. However, when you create the lighting in the computer graphics world, usually, you will cost many effort and attempt to achieve the desired effect. Although the three-dimensional software can free to create any type of lighting freedom for the PPP, sometimes it difficult to makes sophisticated image creation lifelike appearance. When you difficult to achieve the lighting effects in a particular scene, learn some of the basics of traditional lights is usually helpful.

 

When shooting PPP at bright outdoor, photographer and lighting engineer are sometimes use the reflector or assist lamp to ease harsh shadows.

 

- What is the purpose of the light?

In other words, what’s the tone and atmosphere of the scene? Express a tone in the light for the entire image appearance is very important. In some cases, the only objective is to clearly see one or several objects, but this is generally not the case, the actual target is quite complex. Lighting helps to express an emotion, or guide the viewer's eye to a specific location. It can provide greater depth of the scene and showing rich level. Therefore, you can ask yourself, what you want to express the tone, when you create lighting for the scene. Whether you set the lights to enhance the plot of the story?

 

- Are there special lighting effects in the scene?

If so, they should be created through lights or other ways? Except the usual types of lighting, many 3D animation software make special effects via incandescent lamps and stereo source material and the freedom of the PPP. Although, strictly speaking, does not belong to some types of light, in the scene, they usually results in the appearance of visible again added. A simple example: visible light shine or glow. Due to these effects can’t be automatically generated in 3D , you need to render them specifically included, and consider their appearance and strengths.

 

- Are there creative reference sources?

When create realistic scenes, should develop derived from actual photographs and PPP in the habit. Good reference can provide some clues to let you know that a particular object and the environment at different times in a day or how under certain conditions. Through careful analysis of the position of the highlights and shadows in a photo, usually the image can be reconstructed fundamental role of the position and intensity of light. By using existing data to reconstruct the original lighting layout, you can also learn a lot .

After considering the above questions, it will depend on different scene, however, there are three basic types of light sources: the key light, adding light and background light, which together coordinate the operation. Provide some clues to let you know that a particular object and the environment at different times in a day or how under certain conditions. Through careful analysis of the position of the highlights and shadows in a photo, usually the image can be reconstructed fundamental role of the position and intensity of light. By using existing data to reconstruct the original lighting layout, you can also learn a lot.
