6. Constraints of 3D development.

6. Limitations of 3D development.

Some of the limitations need to be taken into account of 3D development software. Even though 3D software is ground breaking and an awesome advantage to most industry's including film, animation, architecture, gaming and many more. It also comes with some severe disadvantages.

Firstly the first major problem of the software is that majority of the software available to use is very expensive. For example it is around £3000 for 3DS MAX (dependant if it is in a sale). This is a very expensive thing to buy, not many will be able to afford this. There is other options to choose for software such as Daz 3D, Sculptris and Blender. The free software may not be as for fulling as the exspensive but is much better for those on a budget. All though Autodesk offer supporting packages such as the support for students that it is free for two years. This is one of the disadvantages of 3D software.The final limitation is that the user is restricted to what the program can do, meaning that the user's creativity is then restricted.   

Another disadvantage of 3D software is that it is very time consuming as to make a good high quality model a lot of knowledge is needed. The high tech software presented is already very needing of skills and so when learning a software it takes a lot of time. To combat this there is many tutorials available. There is a very steep learning curve.

   Also another limitation of development software is that certain PC specs are needed to be able to use the application. This means spending a lot more money on more materials in order to work the apps. In a workplace situation the system may be bought for the user but in a non-industry environment it may be quite expensive. The key part of the computer system is a Graphics card this is what renders the images in the programs. The better the graphics card the faster the process of frame rate. The best currently on the market is by NVIDIA and is their CUDA model. The Cuda is computeing architecture that enables major increases in computing performance by using the power of the GPU (graphics processing unit). This helps for many things such as image and video rendering and ray tracing.



A huge floor of  3D software is that the rendering time plays a huge part in delaying the production of any 3D production. For major productions such as the work of Pixar who use 3D software they use rendering farms. These and huge warehouses filled with servers and extra support to help render their scenes. It took Pixar 3 years to render their infamous Finding Nemo. This then costs companies a lot of their budget as it costs in energy bills but also if the scene is not to the animators expectations then it must be re-done and that is then a waste of months.

Usb cassette tape production diary

I started by creating a simple cuboid with the parameters 55mm by 35mm by 6mm. Then using the similar method as the usb plug i then created 2 circles and a rectangle. After turning these shapes into an editable polly i then selected the polygon selection. And selected extrude, the amount wasn't important as it was designed to go through the cuboid. Now after i placed them through the the cuboid i went to the create control panel and selected compound objects menu. Here i was able to select boleon and using this and selected the operant b and the 3 shapes this deleted the intersections.

USB TIP DESIGN PRODUCTION DIARY

First i looked at the dimensions of a USB connector which is around 11x4mm. To fit this i used the customise tab and changed unit set up to millimetres. I then typed 11mm by 11mm by 4mm and zoomed in to the ready made box. I found the grid was too big so i right clicked a snap tool and changed it.

I then flicked to my front viewport. I then created a rectangle with the edge and traced the cuboid. And pulled it away so i can see it. After i changed the corner radius by 0.2mm. I then moved it whilst holding the shift key and hit copy. I then changed the colour or one of the splines to tell the difference but then i needed to connect the two together. To do this i clicked one and converted it to an editable spline. That gives me more tools. I then went on the geometry roll out and selected attach tool and changed the name to USB PROFILE 1.

I then used the extrusion modifier and it added a surface to the shape. I added 11.0mm to the amount. I added 7 segments and copied the shape. I then went into top view and added a box using snap tools so that it sticks to the edges and segments.

With the box i enabled it out of both sides of the cuboid. And copied it. I then used the Boolean tool as it is used like a cookie cutter. Then i clicked pick operand B and deleted the cubes.
