OUDF103 – 3d animation

Process one – 3D modelling is crating the basic shape of the model through mathematical formulas often using polygons, this make up the skeleton of the model. Generally the more polygons used the smother and more detailed a model will be but the slower the rendering time, with more modern models to over come this problem they tend to concentrate on shading to create a more detailed look. Detail is then added with lighting and other effects so that it is ready for animating.


Process two – Animation is creating the illusion of movement thought the use of still images, using similar techniques to are used in stop animation. To create this illusion an image will be displayed on a screen e.g. monitor or television screen then replaced with an almost identical image only this time it is slightly changed E.g. a hand will be slightly moved. This is called tweening with it having a wire frame or skeleton this enables the 3d object to move or be altered. For a smoother motion around 12 of these images (frames) are displayed at within a second.


Process three – 3D rendering is were a three dimensional wire frame model will be converted into a still image each of these images will be made into a frame.


Vertices are a set potion or coordinate which can also help with other information such as colour and vector coordinates, an edge is the line that connects the coordinates. A face is a closed set of edges, so a triangle face will have three edges and a quadrilateral face will have four edges and a polygon is a set of faces, joining up to create a surface.
