Hi - I’m just getting started with shaders, mostly playing with other peoples code. Coming from quartz composer there is something i would like to emulate and is bugging me with many shaders.
So QC and GLSL share the concept of animation being driven by a flaot called TIME. In quartz I would generate time using integrator patch. Giving this patch a variable between -1 and 1 would allow me to control the rate of animation, as this variable sets the rate time accumulates at. Mostly importantly changing this rate gave smooth changes in speed.
Most ISFs i have loaded into VDMX seam to control rate by multiplying TIME by a rate factor - the problem with this is that changes in rate cause jumps in time and jerky playback whenever the rate is changed.
So what im after is a smooth way to change the rate of time in ISF ?
Hope this makes sense - im not fluent in shader speak.
