Typical stages in 3D production pipeline (medium part)

In my last blog, I introduced pre- production and 3D modeling in the 3D production pipeline. As your 3D models are done, the next stage is making your models more realistic or putting effect onto your 3D models. And then, make them alive. Thus, in this blog, I am going to talk about several stages to make those purposes to come true.

UV mapping

The first stage is UV mapping. In this stage you are going to put a coordinate map axis on your model. The coordinate map uses U and V axis, basically you can treat U as X-axis and V as Y-axis. It is helping you to indicate how to put your 2D image onto you 3D model. During this stage you will need to unwrap your model to help you to project the 2D image onto your object. There are several techniques to map a textures onto your object, it depends on how do you want your object look like or what is the shape of your object. Such as planar (two dimensions plane) , cubic, cylindrical, and spherical mapping.

Texture and Shaders

After you make a UV mapping on your object, the next stage is texture and shaders. The texture is the image that you put on you model. It is a bitmap that can be solitary color, your painting or a photographic image. And shader is controls that what your object can do through computer. You can get effects such as light and shadow that will interact on you object with its materials. There are three types of shaders: surface shaders, vertex and fragment shaders, and fixed function shaders.

Rigging

Rigging is adding bones and joints in your model, it work as skeleton to manipulate your object to move in realistic way.

Animation

Once your rigging system is built, you will create animation. In the software 3Ds max, you can create video for you object by setting your key frames and timeline, place your model at different place or in different poses, and film it by virtual cameras inside it.
