Week 38

Markerless AR

Assignment 2


    This week is lab work week for our 2nd assignment about markerless AR. As of ideas for what our project was going to be we had no idea going into this week. The plan we had about making a multiplayer shooter game was not going to work as our game had to be educational and we doubt soldiers are going to be our target audience. Eventually we agreed to make a recycling game after having an argument about this subject. 

We decided that the game should work something like this. User has a 4 types of bins to place wherever he likes. When all the bins are placed, the trash around the bins will spawn and user has to recycle the items. When users click on an item, the item is selected and put in front of the player camera. Then user proceeds to click on a bin which he choose to recycle the item. If the item is properly recycled, user gets a point and vice versa, gets minus points if the item is not properly recycled. The points are here just to make the game more exciting.

Now, when we started making the project, we knew this is not going to be a straightforward development.
When we tried to first run our app, we only got a black screen. Then we found out you need to tick some options in Unity Editor to activate the AR Core. We were wondering why it's not activated by default when downloading the AR Core packages.

The worst thing of all was the build time. Since the most powerful laptop from our group got into an unfortunate accident we were forced to make this app on a Macbook. Even though we've been building the app on a Macbook with a M2 chip which is quite powerful by itself, the built times took like 7 minutes. This makes the development really frustrating since if we want to try to make a small change to see if it works, we have to wait for the whole built to finish and copy the application to the phone again and again.

After we managed to get the app running, the camera had troubles recognizing the plane properly. Our fix was to set the detection just to horizontal which resulted in better tracking and object placing.

On this assignment, we also worked on the code together at the campus as we deemed the assignment was too small to split up.

Week 45 - Working on our final assignment

    Working on our final assignment Week 45 This week we met again on Friday to continue on the project. We started with implementing the broom. We found a nice asset for it and put it into our project. As we tried to implement the grabbing of the broom with the VR hands, we had some issues where the broom was always off.  Since we wanted to use the grabbing script from our previous project because it was working well, we thought this would be the case as well. But we were wrong. So after a few hours of frustration, we decided to put the knife into our Harry Potter game and test it. The grabbing of the knife works well and we didn't know where we are messing up with the positioning of the broom. Then we got a brilliant idea to put the knife as a child object of the broom, position the knife handle where we want the hand to be placed on the broom, and get the right position values. Eventually, we removed and the knife itself and made the broom work. Authors: Patrik Horny, Mircea Dob

Week 44 - Starting to work on our final assignment

     Starting to work on our final assignment Week 44 This week we have to start working on our final assignment. Last week we assign everybody to find ideas on what we could do but in classic fashion, we all came up with crappy ideas that were too complicated to implement within our time limits as well as we all have separate bachelor's to write. We eventually did what we did at the start of every assignment. Started browsing the free asset store and looked for everything and anything. We eventually found a package with Harry Potter wands and we got the idea to do a game inspired by the Harry Potter universe.  After some digging, we found an abandoned project that had the textures we wanted. After importing those assets we decided to make a functional map to try it out.  While exploring the map we made using the assets we found, we came to think "why don't we make a game where you can fly in Hogwartz?". After some thinking, we decided this was the right course of act

Personal reflection - Mircea-Ionut Dobre - 293117

 Personal reflection Mircea-Ionut Dobre 293117 First project - Vuforia For our first XR project, we had to make an application using Vuforia for a marker based augmented reality experience. This did not go well to say the least.  We had constant problems with vuforia. At first it seemed quite easy to implement as we were mostly already accustomed to unity from the previous semester but we ran into problems especially when we started building the app going thru multiple versions of Unity and Vuforia before we got one to run. The light in the room was also a problem when the app was trying to get the marker. We also ran into some problems while getting the gyroscope scripts to work with our android test phone. We only had 1 android phone that was not company-locked (companies won't let you install external APKs on your phone if you have a work profile) so we had to use a Chinese phone. After getting past these problems the compile times on a pretty potent gaming laptop were abysmally
