Ha5 the basics of 3D

  1. 1. HA5 the basics of 3D Task 1 – ResearchUses of 3Dhttp://www.steves-digicams.com/knowledge-center/how-tos/video-software/6-industries-that-use-3d-modeling-software.html Gaming 3D modelling is huge in gaming, this make the games look more and more realistic as the technology advances, although within games the less polygons used the faster and smoother the game will run so developers have watch out.Entertainment (TV and Film)3D modelling is growing in the entertainment field, many films and popular TV shows that areproduced now use 3D modelling, as this is very good for special effects, creating environments andeven removing things from scenes too.Architecture3D modelling has changed the architecture industry as normal is would just be a rendered sketchwhich would be should to the client, now with 3d modelling developers can create the entirebuilding with every detail and show it to the clients who then could do a personal ‘Virtual Tour’
  2. 2. Advertising and Marketing3D modelling artists can help advertisers and marketers depict their products in the ideal state. Itallows companies to render new cars, new product packaging and prototypes at drastic savings. If itdoesn’t ‘play’, they can fix it by merely changing the computer model. Additionally, once they havedeveloped the right rendering, they can use that to sell the item before they have to invest capital inproduction.Science and Geology3D models can be made to simulate experiments and earthquakes, this helps them as they can seethe affects and stresses.Basic PrinciplesGeometric theory -vertices; lines; curves; edge; polygons; element; face; primitives; meshes, egwireframe; coordinate geometry (two-dimensional, three-dimensional); surfaces3D Modelling Softwarehttp://www.hongkiat.com/blog/25-free-3d-modelling-applications-you-should-not-miss/http://cg.tutsplus.com/articles/top-15-applications-for-3d-artists/Blender – is a free open source 3D modelling, sculpting and animation application that can be usedat industry standard for Modelling, Sculpting, Texturing, Rigging, Animating, Particle Simulating andothers, Rendering, Skinning, UV unwrapping , non linear Editing and Compositing.
  3. 3. Google Sketch up –Is a Free Open Source program from Google, Which can be used to create, shareand present your 3D models. Sketch up is great for the community as the models you make (ofbuilding) can be uploaded and used on Google Earth.3Ds MaxPrice - £3,050.00Is made by Autodesk who are the world leadingcompany in 3D Design software. It’s used byprofessionals and students. 3Ds max is a powerfulprogramme that integrates 3D modelling, animation,and rendering tools that enable artists and designersto focus more energy on creative, rather thantechnical challenges.MayaPrice - $3,495Maya is made by Autodesk. It’s Awarding wining, and used in many Post-production studios. Mayahas set tools used for animation, modelling, simulation, rendering, match moving, and compositingon a highly extensible production platform.LightwavePrice - $895LightWave a complete modelling, animation, and rendering package, that provides full functionalityright out of the box. Its said that Lightwave may be one of the best tools you have ever used andmany artist have won Emmys Using light wave.Cinema4DPrice – $959/$3695Cinema4D is very user friendlyyou can choose from an array of different editions and bundles(depending on what 3D environment you are working in). Whether it be post production,architectural visualization, or even engineering, the different bundles have different modules to fityour every need.Constraints
  4. 4. http://blog.designschemers.com/3d-modeling-for-video-games/Polygon Count–3D artist’s for games have to keep into consideration the amount of polygons theyare going to use as game engines will have to render up to 40-60 frames per second in real time tokeep the game running smoothly.The artists will have to think to themselves: How big is my model going to be? How close will thecamera be to the model? (Closer models should contain a higher poly count than models in thebackground and that players won’t get close to). They will also have to consider whether the playerwill be able to see the back of object so for instance buildings in the distance probably won’t havebacks to the .File Size – Like the polygon count the smaller the size the better. The file size of a 3D model will bedetermined on the contents so texture objects will probably be bigger than non-textured object andthe more polygons within the model the bigger the file.Rendering time – There are many ways to render an animation or object.Real time rendering, generates frames as fast as they can be displayed.Offline rendering, renders one frame at a time at desired quality. This will take a lot longer andrenders into an image which will later be assembled into a movie.Games are usually rendered using Real Time rendering but Movie animations done by say Pixarwould probably use Offline rendering.
