What is VFX? ● stands for Visual Effects ● many people confuse visual effects which are digitally created, with special effects, which are practically created ● includes many different areas such as fire, smoke, water, and other simulations What makes up a strong VFX artist? ● coding skills and technical merits ● artistic eye ● creative problem solving skills to adapt current software and hardware to ever more challenging technical problems as well as developing new methods Particle systems ● widely used to create natural phenomenon such as fire, dust/dirt debris, as well as creating seemingly “solid” structures from many, many smaller components ● an emitter releases a specified number of particles, which can have images, geometry and other components tied to them ● particles can then be directed by applying digital forces to them such as wind, gravity, turbulence and life cycle Fluid VFX ● deal with simulating liquids as well as some solids, smoke and fire ● collision detection is used to enable the fluid to strike a collision object and then react accordingly ● the appearance of a fluid sim can be art directed by utilizing physical forces such as gravity, turbulence, time and viscosity Rigid body simulation ● used to break/crack geometry into smaller components based on an applied force ● have main components that are animated or art directed, which then influence the remainder of simulation to achieve a very specific look or performance
