This tutorial will guide you about texturing and shading for any model.Texture helps us to find the detailed study of 3d object. Texture is mainly applied on the polygon. The vertices are mutually coordinated with one another in polygon and in this way they causes for the procedural texturing.
This method is suitable only for the single texturing object whereas the Multi-texturing help you to apply texture on the single object with more than one time. Bump mapping is also used for Multi-texturing and it is becoming popular now in the video games and film industries. Although the rendering is done with pixel setting therefore it measures the pixel quantity with texture filtering. If you are required to apply texture on the outside of the object, then you should use wrapping.
On the other hand, shading is assumed to the lighting matter of 3d objects. It helps you to clear the darkness of the object for better resolution at rendering stage. Shading is required after the basic drawing of 3d object. Apply the shading at lighter area in the object and make it good looking and charming.
Color of Object
Try to draw the object line closer to the shading because it will provide your object more lighting. It is common concept to think shading as the source to change the color of object. But the experts take shading with meaning of assigning color for the higher resolution in rendering purpose. The actual drawing of the object has edges lines. We remove the edges line at first to make it smooth and fine shape.
Then it is applied shading with the light sources. The light source brightens the object, another think that is necessary to mention here is that the flat shading will appear with flat boxes in the rendering process, therefore always use the smooth shape for rendering. A quick review on this concept is being showed in the following video.
