Upon instantiating a Perlin object, you can produce a smoothed Perlin noise value like so: Perlin p p.noise (x,y,z) Where x,y,z are floating point values representing a position in 3D space. If it matters, I’m running the board on 16MHz external. The main files youll need are Perlin.h and Perlin.cpp. All SPI access will default to bitbanged output”Ĭ:\Users-\Documents\Arduino\libraries\FastLED-3.1.3\FastLED.cpp: In member function ‘void CFastLED::delay(long unsigned int)’:Ĭ:\Users-\Documents\Arduino\libraries\FastLED-3.1.3\FastLED.cpp:133:9: error: ‘yield’ was not declared in this scopeĮrror compiling for board ATtiny x4 series.

#Perlin noise c code
The code I’m trying to upload just uses the inoise8() function: #include I’m using these cores, which work very well. I thought I might try it on ATtiny84, and I’m not too surprised it didn’t work. Hey, I posted the other day asking about Perlin Noise for Arduino, and ended up going with the FastLED library. Perlin noise is a procedural texture primitive, a type of gradient noise used by visual effects artists to increase the appearance of realism in computer graphics.
