Image gallery, upload to server

I made my first attempt at uploading to the MM server yesterday, and it worked perfectly. I had a few more bits and pieces to correct in the meantime, and now I have all that done and the project is uploaded. Mission: complete!

I created an image gallery for the about page because I thought the text needed to be broken up a bit. I used a simple solution using the CSS box model rather than using any jQuery. Again, I just wanted it to be nice and simple, as the Unity application is the main focus of the website and, if scaling this out, it would be affiliated with an official site and would not need this page, other than to explain the concept of the museum.

I am very happy to be finished, now I just need to put the finishing touches on the report. It's been a long process, often interesting and sometimes very frustrating, but I now know how to create a web application in Unity and this could be very useful in the future.

Rectifying issues in testing

Based on the feedback I received from testers, I had to make some changes to the lake scene. I created cube barriers around all the walls of the terrain so the user can no longer fall (or jump) over the edge. I initially tried to use planes, but there are some fall-through issues with these, so cubes were a better option.

I took on board the feedback about the sparsity of the scene, and did some experiments with the default tree in Unity. However, because the scene was not done to scale, it was difficult to get the tree looking realistic next to the hills and objects, so I decided to leave it out.

An average-sized tree, dwarfing everything in sight.

I also changed the music to something more appropriate; I am using Christy Moore's Ride On, which is Irish-sounding without being too cheesey. I may have to change this based on copyright issues. I then included player instructions on the splash screen.

I think I now have the Unity part of things totally completed. Yay! It's just a case of fixing up the website.

Testing

I have tested the nearly-finished project on two groups, one in the 20-40 age bracket and one in the 60-70 age bracket. 

A female tester aged over 60 really liked the project; she thought the landscape and models were impressive. She also found the controls very simple to use, an issue I had been worried about. She suggested that there were not enough objects to click on and look at; this is a valid criticism, but for purposes of this project it was necessary only to have one working object as making more would be repeating work already done. I would definitely expand the amount of objects if continuing work with the project, however. She also suggested the landscape was too sparse and that I should add trees and vegetation, a suggestion borne out by members of the 20-40 group.

A male tester aged over 60 thought the project was useful from a historical point of view. However, he had no interest in learning to use the controls and asked that I navigate around it for him. This could be a problem, as many people of this age group will not have  used similar applications such as video games and may not be interested in trying. It may be necessary to make more intuitive controls of a click-and-drag nature. This was my original plan but time constraints did not allow for it. He also wanted to get inside the crannog, which was part of my original plan but I did not follow through on it due to my decision to make the museum open air. In later incarnations I would be willing to make explorable architecture, which will involve significant work with lighting and baking textures. Again, time constraints do not allow me to do this at the moment, but it is something to think about. Both members of this group wanted the Unity player to be smaller, so that the whole player is viewable as you click into the homepage, so I will attempt to do this.

There were four testers in the 20-40 group, 3 male and 1 female. All enjoyed the project, but many were curious about what would happen if they went off the edge of the terrain, so it will be necessary to add more barriers to prevent this. One expressed a desire to explore the lake, but this goes beyond the scope of the project, as there is no facility at Lough Gur to explore beneath water level. One male, aged between 25 and 30, thought the texture on the crannog needed work. I agree, but this is again something I would do in conjunction with making it explorable.

During the testing process, some of the browsers were more suitable than others. Safari is currently my preferred browser for this project. It works well on Firefox as well, but many people use very restrictive pop-up blockers when using this browser, making it impractical. I will advise my users on the best choice of browser on the homepage, perhaps in the splash screen on the web application.

GUI - Sound toggle and exit button

I have added sound to the project, and I have created button functionality whereby the user can toggle sound on and off, and also exit the Unity application to go back to the home screen. I think sound makes the project more interactive and immersive. The button functionality involved more JavaScript code, which the Unity Community is very useful for. With a lot of this kind of functionality, it's considered quite basic so a lot of people have already done it, and it's not too hard to find examples online.

This one was useful for the on/off button:

The exit button really only required the use of the Application.LoadLevel command.

Unity embedded!

I finally succeeded in embedding the web player with suitable dimensions. I decided to use the web page generated by Unity in the build stage and adding my home page elements, rather than attempting to get the player into my already-created homepage, and it works much better. Now all I really need to do is get the cursor constrained to the centre of the application and it has all the functionality I need it to have. Exciting times!

 

Terrain barriers

I have just solved the problem of the player falling into the lake and/or off the terrain by placing cubes at the sides of the terrain and turning off the mesh renderer. I placed a plane on top of the water of the lake and again turned off the mesh renderer, and the controller can now happily traverse the lake should he/she so wish. I feel like I've solved a lot of issues today. My website and Unity application are now more or less complete, I just have to iron out a few more issues. Nearly there! (I hope.)

Splash Screen and web embedding

I created a basic splash screen and loaded the game to playing on clicking the button. It looks dreadful but at least I have the functionality there; I will edit it later.

The problem with the stretched application continues; I have uploaded to the web page but it stretches across the entire browser and does not look good. The code I used is available here:

http://docs.unity3d.com/Documentation/Manual/WorkingwithUnityObject.html#initPlugin 

I have posted on the Unity forums to find out if anyone can help, as I can't figure it out. Hopefully that will show something up. 

Another issue is that, in the finished application, when you click on an object to open a web page, it doesn't open in a new tab, rather it opens in the tab you have open so you have to browse back to the application and restart it. This is a pretty big problem so I am looking into ways to fix this now.

This is how much the application stretches :(

 

Level complete!

I've just finished the level - you can navigate round the environment, and click on objects to retrieve information on them. You can also rotate the macehead to get different angles on it. Now all I have left to do in Unity is create a start screen and possibly add some audio, anything else I need to do within Unity is optional. I also still need to work on the website and the embedding process but the main task is done. I'm going to go and reward myself with some GUI tutorials. Hooray!

First Person Controller and terrain constraints

My terrain is essentially finished, I might add some trees and grass later on but at the moment it is the shape I want it to be, apart from one small problem: I can't currently prevent my first person controller from going into the lake and not being able to get out. I have used step offset and slope limit to prevent him from going up the hills, but unfortunately I'm not sure how this works in the opposite direction. I've tried smoothing out the terrain by raising the parts of the lake that I've lowered, and it may just end up being a tedious process of doing that, but I'm sure there is also a scripting method I can use so I have to find that out.

This is what you can see from the lake. But you can't really do anything!

Outdoor museum?

I rebuilt the terrain to look more like the natural landscape of Lough Gur. I roughly copied the shape of the lake. I placed mountains around it. These do not follow the topography of the real Lough Gur, as I would need access to digital maps to be able to do a really accurate depiction, so I decided it was best to approximate it and take artistic license with it. I imported my assets with textures, and the size of the assets compared to the terrain was not what I expected it to be. I tweaked things a little bit, and then placed the plinth and macehead next to the lake. I really like the way this looks, and I would actually really like to leave it like this and do away with the architecture. The idea here would be to dot several plinths around the landscape and have the user navigate to them, clicking on each item for information. It allows for an outdoor museum where you can look at the objects in the context of the environment rather than inside a building. I may still place the crannog somewhere as a museum object, but I think the idea of the openair museum is much more engaging, and I prefer the aesthetic sense of it.

Unity file embedded to web

I've had a certain amount of success in that I have managed to create the basics of my Unity application and embedded it to the homepage of my online museum. It has not been seamless; the textures still aren't there, and I have a basic rotation on the macehead but it is not working the way I want it to. This I will sort out soon. At the moment the main problem is the way the web player appears in the page; I was hoping for a small window like in the actual Unity file in game mode, but the window is elongated. I also haven't compiled it at my desired start point and will have to look at creating a GUI as well. That said, I'm very happy with the way things are going so far. This is still my trial file so hopefully I will have these problems ironed out before I get the real thing sorted out.

As you can see, this screen shot shows just how problematic the game window is, but I should be able to sort this out.

Inside the museum

I may not have the textures sorted out yet, but I have a macehead on a plinth inside the crannog-museum, which is progress. I'm not made about the scaling here - I modelled all the game assets to scale in 3ds max and it looks like I have a lot of extra space in the museum that I don't need. I think the scaling is actually correct though, I think it's just that I expected it to look a little bit different. I thought I might have time to model some extra objects, but because the macehead took so long, coupled with the fact that many other Lough Gur objects are of much more unusual shape, made me stick to just one. In a larger scale production I would definitely model more - I would have liked to have the shield done. I tried to get the texturing sorted as well, but to no avail as yet. I think the key is to obtain full functionality at the moment, and to worry about the rest later.

I do also have a first person controller in this scene, but I need to add colliders to the objects to prevent the FPC walking where it shouldn't be walking, and I also need to animate the macehead and add the webpage with all its information.

More 3Ds max assets

Unity 4.1 has been installed to my machine in college but at the moment my files will not open in it. This is very frustrating as I had planned to do a lot of work in Unity today. I did manage to import my crannog to a new project in Unity by converting the max file to .fbx and bringing the textures in separately, but none of my older projects will work at the moment. Instead I decided to make some more assets for inside my museum, including a plinth with a cushion on top. This isn't done with the correct textures, but I did learn some interesting things about texturing for the purposes of the project. I think for my crannog I need to up the values in real-world map size to make the mud texture look more realistic. I might also attach a separate bump map instead of relying on attaching the mud texture to both bump and diffuse. Here is an image of my cushion file:

The swirl pattern you can see on the cushion is actually added to the bump setting so it looks like the swirl pattern is indented into the pillow. I will do some more work on this over the weekend.

The tutorial I followed is here:

Objects in 3Ds Max

I have made a crannog that will provide the setting for the museum in 3Ds max, and I'm in the process of making a macehead, one of the items in the museum. At the moment I have no plans to put more objects into the museum as the project is just a prototype. The object creation for the crannog was very simple; I made a circle spline and extruded it, then applied a shell modifier to create thickness. I converted it to an editable poly, and cut the door out of it using the Boolean compound object. The roof is a sphere cut in half and then reshaped using soft selection and scale. The textures are problematic; I have a straw texture on the roof which looks okay but not perfect, and any mud texture that I have tried to make does not render properly, so I will have to find a solution to that. The macehead is proving more problematic still; I've been working on it for a while and I've been using the Boolean compound object to create the shape I need, but this causes problems with the topology and the textures. The different smoothing modifiers aren't of much use in this regard. I have also tried to create a line and then add a lathe modifier to achieve the shape I'm looking for, but that hasn't been successful. Back to the drawing board for the moment...

More Unity

I'm exploring the use of scripting in Unity which has proved really helpful. What I'm doing is JavaScript based, which is great because we did it last semester so I've a head start on the understanding of it. It has been quite straightforward so far. As well as that, I've been able to create scenes with controllers that I can navigate with. Unity has a lot of templates for outdoor terrains, but unfortunately none for indoor terrains so I will have to model those in 3ds Max. I've really been enjoying working with Unity so far. Simple commands can have really cool effects.

 

Unity experiments

I'm currently trying to open a webpage from a Unity game with a click of the mouse using the Application.OpenURL function, but it's not working just yet. I've been playing around with Unity a bit more and it's very interesting to see the possibilities of the software. Here is a scene of a terrain I created and textured. The inbuilt presets in Unity are very handy and there are also options to import others.

 

Modelling the objects

Each of the objects in the museum must be modelled as accurately as possible. This involves measuring the objects based on the measurements given by the documentation. For example, this macehead from Lough Gur is on display in the British Museum, and the museum's website provides measurements for length and diameter. However, as the object is not a uniform shape, I have to calculate the measurements for the varying parts of the object. I am using an image in Photoshop, scaled in proportion, and I am using the rulers in Photoshop to calculate the various measurements.

The lines of measurement can be seen here. I am hoping that this level of precision will lead to an accurately modelled object.

I began modelling the object in 3ds max. My initial idea was to model it using Boolean operations to create a compound object made from cones and spheres. I did this on Friday but it didn't provide the desired effect. My current theory is to using the loft function in compound objects, as this allows me to more precisely model an object with non-uniform properties.

Website prototype

The prototype for the site in which the 3D museum is to be embedded. The emphasis is on simplicity and ease of use to make the experience as stress-free for the user as possible.

 

Site design and museum navigation

Here are the initial sketches for the site design as I envision it.

And here is the navigation design for the online museum.

Unfortunately the scans aren't perfect. However this is my initial idea of how the user navigates through the online museum, clicking and dragging to view the objects and areas. This may be subject to change as I am no longer certain that this type of navigation will be practical, but I am waiting to hear more advice from the project supervisors.

Unity

Getting to know Unity at the moment, and working my way through the Lynda.com tutorials. The interface is much different to 3DS Max and Maya, but a lot of the controls are the same, which is useful. Really looking forward to exploring the possibilities here :)

I have some sketches made for the design of my museum itself, I will scan them in soon. It's been tough to figure out the architecture, but interesting nonetheless.
