Keywords

💡Illusions

Illusions refer to visual phenomena that can create a deceptive or misleading perception of reality. In the context of the video, 'master of illusions' describes a technology that can manipulate computer simulations to form patterns or structures that appear random but are actually controlled. This is demonstrated when the cubes form a pattern and the balls fall in a way that seems random but is actually guided by the technology.

💡Computer Simulation

A computer simulation is a digital imitation of a real-world process or system. In the video, the term is used to describe the process where thousands of cubes or colored balls are thrown in a virtual environment, and the technology in question can control their trajectories to create specific outcomes, which would normally be considered impossible.

💡Deformable Bodies

Deformable bodies are objects that can change shape under the influence of external forces. The video mentions that simulating the physics of deformable bodies is complex. However, the technology can still impose structure on these bodies, which is impressive given the inherent unpredictability of their behavior.
