Production Process: Water Lilies Floor Projection Mapping Technical Setup

Floor Plan Measurement



I have chosen my actual location setup at the lobby so that I could proceed to project it with the sensor. The floor plan will be around (Width: 14.5ft & Height: 24ft).

Technical Setup



This is the initial tryout without debugging the exact floor plan measurement. the purpose is to test the sensitivity of the sensor and figure out bugs in the code. The results show the calibration with the sensor together.

Code Debugging


The water ripples keep spawning from the center point whenever a user is detected. Instead of attaching the water ripples under the flower pooler, I have successfully solved the issue by creating a new object pooler for the water ripples. So the water ripple will be another group of objects performing individually.


Another bug is that the ripples of the flower itself spawn randomly. I have solved this issue by restarting the animation again by adding animation events on the blooming animation.

Flower Closing Animation


I have added closing animation after the flowers have spawned for 8 seconds. This is to reduce the chaotic of the pond and enhance the overall experience.

Fish Animation

Rigging in Blender


Experimentations of the rigging to mimic the movement of fish

Experimentations in Unity


I also added animation of fish swimming around in the pond. This is to create a more lively and relaxing scenario of the pond. I create an object pooler to store the fish and add force for the fish to swim. However, I couldn't figure out how to spawn the fish with different rotations.


I have explored further on with different tutorials on youtube. For this tutorial, the fish swim randomly but the angle of the fish are distorted. The main core to solve the issue is the adjust the Y axis of the fish in the prefab.


This is the final outcome integrated with the pond. The fish swim randomly in slow movements gives a calm and relaxing feel.


Actual Site Setup


I have tested the projection on the actual site, the scale is similar with what I've tested in IIS room.

User Interaction




For the final visual outcome, I have increase the size of the water lilies and add depth for the fish. I have also change the low poly rock to look aesthetically nicer. I also added animations for the water lilies pad. When users hop across the water lilies pad, it will trigger the animations of floating up and down.

[Interaction 1] Flower-Blooming Mechanism Development Challenges

Image
I have encountered multiple challenges when developing the structure for the flower-blooming mechanism. It took me one whole month++ to iterate the design and the whole structure for the flower-blooming mechanism to ensure it is doable for future production.  Design Development Output Arm For my initial design for the output arm, it is just a stick. My thought on the structure is by attaching the wires on the petals and wire around the output arm. However, it is not doable enough as it will be very troublesome for future mass production. Thus, I was advised to create a clamp for the output arm to increase the stability of the overall structure. At first, I don't get the idea. I just extruded a triangular shape from the output arm, and it looks horrible and serves no purpose.  I sought help and get some advice from experts on the clamp who specialize in engineering. I also further modified the model on the length and shapes to evaluate the best design for the mechanism. Fo...

Final Prototype: Night-Blooming Flowers Physical Light Installation

Image
Finalized Flower-Blooming Mechanism Design Plan 3D Printed Mechanism The finalized printed blooming mechanism seems stable with self-locking nut. I test-run the mechanism and it works fine at this stage. Blooming Motion without Petals  5 Output Arms 6 Output Arms Blooming Motion with Petals Pulsing LEDs  Pulsing Light Effect 1 Pulsing Light Effect 2 Both light effects have experimented in the early stage. However, further refinement and debugging will be done to match the art direction of the overall project. Core Experience Video The video below demonstrates the core experience of the physical light installation. Current technical production that have been solved are: Connection between Master & Slave Arduino Flower-blooming mechanism [Stepper Motor] LEDs Pulsing Effect Heartbeat Detection Next Plan: 1.  Exploration on fabrications        -Design & Evaluate choices of material and art style 2. 3D print all the compartments (5-8 sets) 3.
