Hi, I wonder how to create effects and animation like the picture above.
the animation : animation
Can anyone point out a direction or key technique? Any hints would be appreciated!
Hello @aliluyabiti,
welcome to the community!
You can think of this animation in the way of using a Grid SOP with 2 columns and a few rows which would get extruded. The necessary Extrude SOP uses the input geometry’s normals for the extrusion hence you will need to grab noise values for each point and assign it as a normal. The Noise operators all have coordinate lookups from the input but while using the Noise SOP would seem useful here, in this case you would want to utilize the Noise CHOP to prevent either side of the bars to have different extrude values.
Generally you can implement this using SOPs and CHOPs as in attached example but things get a bit unperformant quickly - I would suggest offseting vertices via a GLSL MAT instead.
