Below is a short introduction to the application of linear fall off animation techniques within Blender's geometry nodes system. The visualization depicts a discarded bottle being torn apart and its remnants tainting our waterways as a silent threat to our wildlife.
The United Nations sustainable development Goals act as a blueprint for current and future actions to achieve peace and prosperity for people and the planet. The 17 interconnected goals address a range of global challenges; everything from cliamte change to inequality. We we tasked with selecting a goal and using Adobe's software range to produce a piece of digital media. Our team chose to raise awareness around goal 14: Life below water
Blender 2.9's addition of geometry nodes acted as a medium for controlled particle effects and were used to explore different methods of object disassembly. We settled on dispersing the plastic through means of a 'beautiful' and 'vibrant' explosion, and proceeded to maintain the particles in the waterway while only revealing them through light refractions. A linear fall-off method was used to rig a field effect and achieve fluid light and geometry controls.
Our team employed Adobe premier pro, to composite the animation and adjust several media values such as time interpolation, audio, vfx and lighting. To create contrast between the two scenes a cooler blue hue was chosen to represent a clean water body. Below is a snapshot of a before and after frame showcasing Blender's denoising algorithm and Premier's colour correction capabilities.
