Código para el efecto de onda de un cubo de 8x8x8 LED Arduino

Quiero codificar la animación del efecto de onda como se ve en los primeros 7 segundos de este video .

Así es como funciona mi código ahora. Utiliza 9 registros de turnos (74HC595); 8 para las 64 columnas y 1 para las 8 capas.

¿Cómo debo hacer esto? Apenas entiendo el código de abajo. Dibuja un cubo en expansión.

/* Voxel Shield Sketch
  Controls a Light Emitting Diode(LED) Cube of 8x8x8 voxels arranged
  by 64 columns(anodes) and 8 layers(cathodes).

Básicamente, para usar el flujo del programa en este código, necesitas dividir lo que ves que está pasando allí en distintos marcos. Luego reemplace el bucle con llamadas a cada función de cuadro seguido de dibujar (). Los cuadros son instantáneas del cubo espaciadas uniformemente en el tiempo. Cuantos más fotogramas tengas, más suave se verá la animación, pero más memoria flash tomará el programa.

En las funciones de cuadro (por ejemplo, cuadro, cuadro 2, cuadro 3) de su ejemplo, los bits que se establecen en "1" en el búfer de cuadro (es decir, la variable de matriz de cubo) son los LED que están encendidos en ese cuadro, y los que están configurados en "0" están desactivados en ese marco. Cada capa tiene 8 LED, por lo que hay un bit por LED. Solo tiene que mapear y su patrón de LED por cuadro.

La creación de las funciones de fotograma codificado se puede hacer a mano de esta manera, mediante secuencias de comandos de la secuencia de fotogramas. Creo que hay ejemplos de personas que han delegado esta parte a una PC que envía marcos al Arduino a través del puerto serie para obtener animaciones más elaboradas / más suaves sin tener que almacenar todas las funciones de marcos en el flash.
