  • 1. 3D Animation Task 2 –Laymen’s guide to the Theoryof 3D
  • 2. Applications of 3D 3D animation isnt just used in films . It is also used in many industries. These include: Visual effects Games Architecture TV idents Simulation
  • 3. Displaying 3D Polygon Animation Programming interfacesAn example of a application programminginterface (API) is Direc3D. This program isthe base for the graphics API on the Xboxand Xbox 360 . It is used to render 3Dgraphics in applications. Graphics PipelineThe graphics pipeline is the process thattransforms a 3D image into a twodimensional screen.
  • 4. Rendering Techniques Distributed RenderingIs the process of distributing a single ender job across anetwork of computers. This reduces the renderingtime of a frame. EnginesRendering engines render out the 3D graphics based ofof the models and textures it provides. Commonexamples are OpenGL and DirectX.
  • 5. Rendering Techniques LightingEverything in real life reflects light. Light sources areadded to 3D Animation environments to create apossible shadow which would need to renderedproperly to make the object look realistic. TexturesTextures are added to 3D Animation to make theobject look more realistic and to be able to decide howthe texture effects the lighting and reflection of lightoff the object.
  • 6. Geometric Theory VerticalsVertices (a vertex) are the points in a shape where2 lines connect. LinesLines can be changed n 3D animation. They can becurved , straight or smoothed. CurvesCurves are either distorted straight lines orseveral straight lines put together to create acurved shape.
  • 7. Geometric Theory PolygonsIn geometry a polygon s a flat shapeconsisting of straight-line segments. Motobjects in 3D animation are made frompolygon as the basic shapes then reconfiguredto get a specific shape. FaceA face is any flat part of an object. For examplea cube is made up of 6 square faces MeshesA mesh is the wire frame that shows theoutline of an object. Every object created in 3Danimation has a mesh.
  • 8. Mesh Construction Most models and environments made in 3D animation are made from primitive shapes and then adjusted. For example a table would be made out of a cuboid rectangle and 4 cylinders. This would then create the mesh for the object. Everything made in 3D animation is straight. For example a curve is made up of many straight lines to give it a curved look. The more lines used the more smooth the surface would be.
