Lidar Project Experiment

Interaction

User have to tap around the pond for interaction. Different graphic elements serve different functions. For example, the leaf is to trigger the animation of the leaf with the lotus with different color is to change the color of the fish. Besides that, there are water ripples on the pond whereby it follows the hand movement of the user when tapping around.

Process ( Graphic assets )



Process ( Coding )





This code is to create a limitation for the lasers that shoot from the device. This is to prevent the lidar from detecting  unnessasary rays.


There are two parts of codes can take note of. For the first function, we have to code in order for the leaf to trigger the animation of the fish. We have to set tag on the leaf  to tell the system that the tag is collided with the user touch and thus instantiate the fish. Besides that, we set IE NUMERATOR in order to create a respawn delayed so that the fish doesn't keep on respawning until it loses control. For the lotus part, we try to wrap the whole fish into an gameobject known as "currentFish" and get the spriterenderer component in order to change the colors.

Conclusion

Overall, this is a good start trying out Lidar and understand how it works. It may be challenging for me in future to create more interactive works!

IxD Project: Floor Projection Mapping Setup (Critics & Refinement)

Floor Projection-Mapping Setup Critics & Feedbacks There was a critic session held to get feedbacks and critics from peers and lecturers. I will list down all the critics below. First of all, the animations take too much time. It does not have a rigid reason for the user to continue stepping within the circles because there are no animations playing and the feedback from the lines is too subtle. It was suggested to add some narrations to let users know what's the purpose of the graphics and animations. They should know what's the point standing and stepping around the circle. I should cut down the time and add some audio to improve the overall atmosphere.  Secondly, the feedback from the lines is too subtle. It's not inviting enough. Thus, I should tweak the formula and smooth time in order to get instant feedback when the user steps on it. For right now, I should minimize the smooth time to get very engaging feedback.  Thirdly, I was suggested to take out the looping o...

IxD Project: Production Process (Coding Design Development)

Image
Design Development This project is very challenging than usual because it uses visual coding which is very new to me. Before starting the visual on coding, I've tried to develop some visual to see how it looks like. I've tried to see and compare how does the circles will look like if added with dotted circles. Lines without Dotted Circles Lines with Dotted Circles Unfortunately, these designs look bad because I feel they look like Indian Diwali and it doesn't match with the overall look and feel that I want.  Design Development with Coding Formation of Circles with Joints At the very first stage, I've learned something very interesting which is creating circles using coding. This is very new to me as I never explore this kind of coding before. This feels like bringing back to my secondary life whereby the formula and calculations to create a perfect circle is being implemented now on coding. From this coding, I've understood that by instantiating the joints, it will...

Case Study 2 - MORI Building DIGITAL ART MUSEUM: teamLab Borderless

Image
      Introductio n       MORI Building DIGITAL ART MUSEUM: teamlab Bordeless is the world’s first digital museum that displays digital interactive arts. It is created by art collective, called teamLab and located in Tokyo’s Odaiba district. Teamlab Borderless is also known as a world of artworks without boundaries because it is a museum without a map.       The museum has 10,000 square meter spaces that uses 520 computers and 470 projectors. It is filled with more than 50 pieces of digital artworks. The 3D digital arts move freely and constantly in motion from one exhibition to the next so that the visitor can immerse themselves with the wonderful artworks together.   Interactions The artworks are spread across the museum’s five zones. The first zone is called ‘Borderless World’, an interactive digital landscape where visitors are encouraged to create their own path. People can walk through digitized waterfalls and touch luminescen...
