3D Interactive Furniture Demo 02

In-between projects I continue to tinker and play with new tech, software, and areas of interest. Usually these side-projects are different from the typical 9-5 projects, but allow myself to look, play and develop new technology and ideas.

Anyway, following on from 3D interactive test 01, this latest revision shows some changes, mainly the inclusion of drop-down menus, and a new way of rotating around the object (the user now clicks and holds down the left mouse button, then moves the mouse) is much nicer to use.

At this stage of development, the main purpose of these demos is to build functionality, hence the very standard looking menus, but once the functions and workings of the app are working, adding the finer detail and visual elements is the easier part (in theory!).

Launch 3D Interactive Furniture Demo 02

The app is built with Unity 3D, which very knidly allows the app to also install and run on mobile devices as well as the web. An augmented reality version is also being developed which I will record very soon to show.

Any comments, please let me know!

3D Interactive Furniture Demo 01

Recently Unity3D (a fantastic piece of software to create interactive projects and games) became free, along with features such as real-time lighting, and fancy materials.

I've wanted to have a play with Unity3D for a while, so during a bit of downtime I opened it up and created a quick test project to experiment with and play....

Launch 3D Interactive Furniture Demo 01

At the moment, to change the furniture style, press buttons 1, 2, 3, 4, and use your mouse to rotate around the chair, and the mouse wheel to zoom in and out.

The next stage is to add buttons (some programming needed, which I know very little of!), and to also give options to change colours of parts of the furniture. The app can then be ported to tablets, phones, desktops, as well as websites.

Currently the 3D Interactive Furniture Demo is a very basic demo, only really scratching the surface of what is possible.

Augmented Reality Testing & Development

During non-project time, I like to get stuck into some to something further my skills, improve my portfolio,  or sometimes to do something different. Recently I have been pondering the use of augmented reality applications.

I have always had an interest in real-time applications, mainly architectural walk-throughs or gaming, but augmented reality feels more exciting and more engaging than walk-thoughs. The idea that you can hold something digital in your hand, or view the world around us differently to what is perceived by our eyes, is a very strange concept. It's also something very hard to explain unless you can show someone, but I guess this is the same for 99% of new technology.

The other reason why I'm taking an interest to augmented reality is the craze with "3D" TVs and films. "3D" TV isn't really 3D, it's just some added effects to try to trick our brains into adding depth to what we are seeing, and to be honest, I think it ruins good films, and is a gimmick to sell bad films.

Augmented 3D, or even 2D, is different, and allows the user to see the content how ever they wish (to an extent). This for me is 3D, and this is what makes it exciting.

This quick video shows 3 examples I have put together to simply explore the workings and possibilities of actually making something useful and deliverable. The main aims for these test was to see how well it worked on various media, how quickly an app could be made and to try to see it's limitations. All of the tests are very basic, but each explores different techniques and features.

Ikea's 2013 catalogue looks like it will feature some augmented elements, as well as links to videos and other content. I believe this is Ikea's way to get customers to interact on-line and through their mobile, rather than using augmented reality as a tool, which is fair enough, so long as it engages and doesn't become tedious or boring.

So the future does look slightly more augmented, but will we see much more in the coming years? The technology is here and evolving fast, but maybe it needs a games console, film, or something else to really spark it off. Sony are creating the Wonderbook, a Harry Potter augmented story telling game, using a magical book, allowing the user to interact with the game. Maybe this will be a massive hit, or maybe it will pass by as simply "another game for kids". The possibilities of augmented reality, for me, are very interesting, and I can't wait to experience some real 3D in the coming years!

Be sure to keep an eye out on my blog for more updates, and testing, as I'm sure there's more to come!

Mobile 3D Interactive Walk Through Test 001

Recently I have been exploring the use on 3D applications on mobile devices, and the first step was to build a basic scene, and test to see how well a 3D environment would work on a small mobile phone.

This is a quick video showing the test application which uses Unity3D to create an interactive first person walk-through on a basic smart phone. The phone used was the HTC Desire S.

Surprisingly, the demo runs very well, and although the HTC Desire S that I used is only a year old, it is by no means the most powerful smart phone out there. The release of the Galaxy S3 with it's more powerful dual core processor and slightly larger screen, is likely to be perfect for this type of hand held 3D application and, I'm sure pretty intensive 3D environments can be achieved as better and faster hardware is made available.

Also what was useful to learn from this demo was the navigation, which after only a few minutes of playing, I was able to quickly navigate around the environment. It also felt very comfortable and easy to use, which is very important.

This simple test gives a quick insight into the use of 3D applications on mobile devices. This demo was by no means a finished project, but a demo to show how it works, what it looks like, and how well 3D performs on an average smart phone. It was also good to try to figure out a work-flow for this type of project. Moving from 3Ds Max, to Unity3D, then to the mobile was tricky, but relatively straight forward after some testing.

If you would like to know more about this application, or would like to try it for yourself on your Android phone, please drop me an email!

As mentioned in the video, the 3D environment was created by Marko Dabrovic and can be downloaded here hdri.cgtechniques.com/~sponza/files/

Interactive Test 002

Here is another interactive test, this time with a more traditional exterior environment.

Click here to have a play around!

I wanted to keep the emphasis on the building it's self, but also to explore some of the nice features of Unity Pro, and to see whether it is worth the price, or whether to stick with Unity Free. Unity Free is brilliant, and I love the fact that you could build an entire game just using the free version if you wanted to. However the features that Unity Pro has that are missing in the free version, are the lovely, juicy bit we all love, such as real-time shadows and post-effects.

In Interactive Test 001, I built the scene using 3Ds Max, Vray and Unity Free. With this test, I used 3Ds Max and Unity Free, and a very small amount of Vray (only for the reflection cube maps). With Unity Free, you don't have real-time shadows, so all the light info has to be rendered to a separate pass, and don't get me wrong, this can often be a great way of achieving great results, but the time spent unwrapping objects, tweaking UVs, rendering, and then realising that something isn't right, and going back through the whole process again and again can be very long and tedious. With Pro, you have real-time shadows, which eliminates the need to bake lighting, but can give flatter results, due to lack of GI, but for exterior environments like this, I think the advantages of real-time lighting out-weighs the benefits of baking lighting and GI. I may do a test with the Interactive Test 001 scene with real-time lighting, and see how they compare. I'm guessing the real-time version won't look as nice, but, the time saved might be the key to making this process one that could be put into a production work-flow.

So far I have barely touched the surface of what Unity can offer, but already I think I am achieving nice results, that should run across many different PC, and other platforms too such as iOS and Android. I am finding it hard however to program in any features, but the Unity forums are great and answer pretty much any question, whether or not I understand the answer!

I also had a quick play with the built in tree editor (hence the crappy trees, I need more practice!), which again added some nice flexibility, and the fact that they slightly move with some added wind, makes them a nice little touch. I added a quick function to hide the trees also just in-case they killed any PCs (please let me know if you have any trouble with the file!) but this also made me realise how useful real-time shadows are, as when the trees are hidden, the shadows also hide, something that would be very tedious, although do-able, with baked lighting.

So, that's test 002 done, let me know what you think, what would be nice to add and to do, and whether or not you can brake it!

And before anyone asks, I really don't know if the Pro version is worth the extra cash over the free, I guess a few more tests and I might be able to tell you!

Updates will follow!

Interactive Test 001

Recently I have been playing with Unity3D and trying to get to grips with it all. I'm really excited by it, with cross platform publishing, including iOS and Android, as well as a pretty straight forward interface, and a logical way of doing things. I'm not saying it's perfect, there are many glitches, problems with graphics, and I am still trying to figure out the best work-flow to make this

kind of application easy to publish, but it's definitely going in the right direction!

Anyway, click here to play with the first of hopefully more testing and development of interactive applications.

The model is originally from Marko Dabrovicand can be downloaded here. I just like the model, and it works perfectly for this type of testing.
