Hello Everyone,

The previous 8 weeks went by both so slow and so fast. On one hand, I don’t even remember when I took my drone license exam, but on the other hand, I feel like my first day of work was just yesterday. I really want to thank Educational Technology department for accepting me for DTSF 2018 and giving me the opportunity to tinker with technology. Thank you Dr. Eric Remy for everything you did for us, we always had the 100% support/help from you. Thank you Kaylynn and Marc for spending time with me and making the workplace more enjoyable. Thank you Renee and for cleaning for us after every single day. Thank you Eric (again), Greg, RC, Chris for the Hamilton Conference. Also, I want to thank everyone, who read my blog post, I really appreciate. At the end, I want to thank the team: Alyssa, Orrin, and Tyler, for co-working with me and spending time together.

Thanks to DTSF, I have learnt a lot about Virtual Reality, the technology which is still growing and has a lot of potential. I really enjoyed working/playing with VR, because I always learn new things about the possibility of VR. I hope VR could work on more platforms with more functionality and portable, so that more people could experience more VR contents.

During my first 3 weeks, I was learning Unity and watching so many tutorials about it. I started making simple mini “games”, where I tested interactions, physics, and movements within VR. I made some simple bowling, baseball, and tennis games. During next 1-2 weeks, I learned about Blender, where I designed my first 3d models, such as a tea cup, table, or assets for my mini “games” (bowling ball, and pins, tennis racket, baseball bat). In Blender, I learned shaping, texturing, UV mapping, and sculpting, which were essential for my project.

My initial project was supposed to be the Virtual Tour of the Gettysburg Battlefield, but due to complications with the National Park Service, I could not take any footage from it. In the end, I worked on the Lincoln Cemetery, which I think was a perfect choice, regarding size, location, accessibility, and historical importance. I did a simple tour of the Lincoln Cemetery, where I 3d modeled the cemetery with Blender, I created the photogrammetry 3d mesh with drone pictures, and I embedded 360 videos. I combined everything together in VR engine, Unity, where I added more interactions with the user.

At the end of this fellowship, I learned so much, I want to learn even more. I can make simple VR content in Unity and 3D model in Blender. Moreover, I can do drone photogrammetry and build 3d models out of it. In addition to what I have learned, I would like to learn making VR content in Unreal Engine, which is a bit more powerful and more options for VR. I hope IT and ET will continue working with VR and allow students to work/play with it more.

Thank you Eric again, I really am happy that I was able to work with you, and be able to learn new skills, which are helpful not only for now, but also for later in life.

Have a good weekend, everyone!

Thank you and bye bye!

Best wishes,

Hello Everyone,

This week, I attended the Immersive Technology Conference at Hamilton College to learn and share knowledge about immersive technology which included 3D modelling, Virtual Reality, 360 videos, 3D scanning, and photogrammetry. Read more about it: here.

I learned many projects from different students from both Hamilton College and Colgate University. All of these projects were impressive, and I found out that I have still a lot to learn, e.g. the 3D model can be very detailed and can take a lot of time, VR experience can be even more interactive, which together can make the experience even more immersive 😉

My main goal this week was to reconstruct the Spanish theater, EL CORRAL DEL PRÍNCIPE, which existed between 16th an 18th century. Under commands of Chris Oechler (Profe O.), I and Orrin were trying to build 3D model of this theater in Blender and implement it in Unity in order to make the VR experience of the historical theater.

Theater consisted of that stage, two side walls, and the back. Orrin is more efficient in Blender than I am,  so he took the stage and two side walls, and I took the back of the theater. Because the theater consisted of 4 floors, I divided my work into layers (each layer- each floor), so that I could build at least 1 floor each day (4 floors- 4 layers- 4 days).

On the last day, I and Orrin tried to merge two projects together and there was a problem with the roof, because it covered all of the 4 floor, making impossible to see the stage from the 4th floor, so we had rearrange the roof again. At the end, we could finally fix it and we could put the 3D model to Unity and experience it in VR. Right now, the theater is just a grey 3D model, without colors. The next step will be adding the material and texture to the 3D model to make it look more realistic.

Thank you R.C., Profe O., and Eric for the trip and hanging out with us 😀 It was a very unforgettable experience for me. I really enjoyed working and spending time with you guys! Thank you Lord Greg from DHi Hamilton College for hosting us and teaching us important functions in Blender and Unity.

Thank you Profe O. for allowing me to work in your project. Hope that I was not that bad in cooperating.

Thanks Orrin for working with me and helping me. Happy Birthday!!!

Thanks Alyssa for proudly representing our school!

 

Have a good weekend,

JHA

P.S. I still think our school should have some squash court.

Hello Everyone,

Belgium is very close to the final. After eliminating Japan in 1/8 and Brazil in 1/4, Belgium will be facing France in the semi-finals. France and Belgium are the best 2 teams at this time, and it will be a very interesting and close match.

Day1

Alyssa taught me how to do photogrammetry with a drone using Pix4D. I made the 3D model of a stone using different photogrammetry programs to test which one will be the most useful, such as Pix4D, 3DF Zephyr, and Agisoft Photoscan. All of them work quite similarly, that means they start with building a dense point clouds from 2D photos taken earlier from the drone, then create a 3D mesh from a dense cloud, and finally add the texture to the mesh based on the photos.

Photoscan- dense point cloud
3DF Zephyr – 3D mesh
Pix4D – Textured Mesh

Day2

I started building the fences surrounding the cemetery. They look quite realistic. I had to calculate the measurements of the fences in real life and convert it to the measures in Unity. I also looked at positions on the map of every fence in order to place them correctly in my Unity scene. My next step will be building the tombstones.

Day3

4th of July – Independence Day 🇺🇸

Day4

I started to model tombstones in Blender. Luckily, the shape are quite simple, so it was not difficult for me. The only “problem” was that there were many different shapes tombstones. It took me a bit longer, but it was not even an issue. The more I model in Blender, the more I get used to working in Blender. At the end, I made 9 different shapes of tombstones. The next stage is to add the proper material and more realistic feel.

Day5

To make the tombstones more realistic, I added the real rock texture on the tombstones that resemble the same material from the cemetery. Then I shaped the flat faces of the model to be more “rocky” by adding the roughness on the faces using different brushes. I used some free brushes from BlendSwap, where users can share their own brushes with everyone and append it in Blender. Here, I used the brushes from here (shout out to rubberduck!).

Have a good weekend!
