C02- 3D Modeling introduction

    A film set is created through various processes.  Before we receive the final rendered image, the texture and colours are worked on and even before that the constituent models are prepared. Here onwards, we will actually be working on modeling, animation and rendering step by step.

CS3D-C02A-Introduction

    We will be able to see our set getting created when we start making the models from our list one after the other and place them in their respective place. A digital set is created after combining different models. If we think of our movie, there are many main models to consider, like table, chair, cupboard, alarm clock and our ‘Tingu’. We also have walls, window, curtains etc. It means, our short film set will constitute all these models.

CS3D-C02B-Object Intro

     Here each individual element is a 3D model. Sometimes these 3D models are moving or animated characters like our Tingu, sometimes they are static or inanimate like the table. Such 3D models are made from small elements or objects. Lets see this from modelling perspective.

     Lets consider our Tingu for an example. Tingu is just one 3D model. But we can say it is composed of different parts like the head, the lamp inside it, Tingu’s body and its spare parts or its base ( base plate).

     Tingu’s main model is made up of many smaller parts. A group of such small parts is called a model. We will also create our 3D models in a similar way part by part. This is the same as we would be animating our film shot by shot.

     If we go into more technical detail, these parts are also made of more fundamental geometric shapes. It is same as how a line is made from points, how a triangle or a square is made from 3 or 4 lines and how 3 dimensional volumetric shapes are made from such elementary shapes. All 3D softwares like blender make use of this theory for creating models. Main shapes are created with the use of shapes like triangle or a square. These squares are called polygons. The four sides are called ‘edges’ and the end points of these edges are called ‘vertex’.

     For the next few posts we will be creating many such models. Few of the complex models will be explained to you and will be made available for download. After modelling is done we will create our set and then move ahead to learn animation and rendering. So, let’s meet again next time.
