Gaming Istanbul 2018 – Developers Conference

GIST 2018 Developers Conference

I explained my previous experiences on VR, mostly about Diesel Express,  my workflow that i used in the games, performance in VR and how to optimize 3D models for VR games. There is the workflow diagram i prepared for the presentation below.

I skipped the concept part and started with a pre-made 3D model of a car. Without UVW’s and vertex paint. I created UVW and vertex paint in 3Ds Max. Then i followed the diagram until rendering the final model in Unity3D. It took about 1 hour.

I Was In Arles How To

This is an artwork which I created as my graduation project for Marmara University-Istanbul. Digitalizing a classic artwork always excites me. While I was working on Microsoft Kinect that idea appeared in my mind. How great it would be to see unpainted areas in Van Gogh’s Bedroom painting. After the graduation exhibition in Marmara University, it also exhibited in amberFest 13′.

This work looks quite complicated but actually it is one of the simplest projects that I made.

I started by searching how to adding skeleton data taken by kinect into a Unity 3D project. I found a sdk which is released by Microsoft for Unity. You can download it from website below.

http://wiki.etc.cmu.edu/unity3d/index.php/Microsoft_Kinect_-_Microsoft_SDK

You will need to install kinect developer toolkit and kinect SDK too. Just after the download has finished, open the Unity3D and run “Kinect1.7UnityPackage.unitypackage”. Make sure all the packages are selected then press import. This will import a package consist of some codes and an example project.

We can work inside the example project by modifying it. When you import all the package you will see KinectSample in the Project window below. Full path is Assets>Scene>KinectSample.8-01

To create the feeling of looking at inside the picture I decided to create a main camera with a target point which is always looked at. Because if you dont use a target point the camera always look the same direction.

I found this code from reference tab from Unity3D’s website.

var target : Transform;

function Update() {
transform.LookAt(target);
}

I copied and pasted this codes as a javascript code in Unity and simply linked it into the camera by dragging and droping. You can create a Java Script file by right clicking in the project window and create>Javascript. You must see the component in inspector menu when you select the camera. Then I created a cube front of the camera for the target and attached it to the “target tag” of the component that i just created inside the camera. You can reach the target tag inside the inspector menu and you can add an object by clicking the circle beside it.

The distance between the camera and the target point is important to make the movement more natural. But it depends on the project.

5Second, I attached the camera to the “03_Head” inside the “KinectPointMan”. The project has 2 skeleton. rainbowMan_v06 and KinectPointMan. I used “PointMan” because the other one vibrating the camera while Point man is smoother.

 

 

 

 

To finalize the project delete the “rainbow man” which we didn’t use and move the camera until the KinectPointMan disappears from the screen. Then you can create your own scene to look inside. I would love to share my 3D model for Van Gogh’s bedroom but unfortunately it was erased with many project which I didn’t sync to cloud after the burned hard disc disaster.

I created a couple of cubes to realize the movement as you can see below. I preserved the skeleton just to show you my body movements.

You can manipulate the distance to see the difference.

I hope you enjoyed this tutorial. See you next time.
