Convert x,y co-ordinate to flat array index. * x and y positions start from 0, so must not be >= 'real' panel width or height * (i.e. 64 pixels or

scale the brightness of the screenbuffer down

The only 'framebuffer' we have is what is contained in the leds and leds2 variables. * We don't store what the color a particular pixel might be, o

non leds2 memory version.

Method to update location

write one pixel with the specified color from the current palette to coordinates

rotates the first 16x16 quadrant 3 times onto a 32x32 (+90 degrees rotation for each one)

copy one diagonal triangle into the other one within a 16x16

set the speeds (and by that ratios) of the oscillators here

create a square twister to the left or counter-clockwise x and y for center, r for radius

Pass 8-bit (each) R,G,B, get back 16-bit packed color

finds edges from faces

mirror the first 16x16 quadrant 3 times onto a 32x32

copy one diagonal triangle into the other one within a 16x16 (90 degrees rotated compared to Caleidoscope3)

copy one diagonal triangle into the other one within a 8x8

copy the rectangle defined with 2 points x0, y0, x1, y1 to the rectangle beginning at x2, x3

expand everything within a circle

mirror + copy triangle (MATRIX_CENTER_X*MATRIX_CENTER_X)

just move everything one line down
