lygia/space/sqTile)make some square tiles. XY provide coords inside of the tile. ZW provides tile coords
Use:
<vec4> hexTile(<vec2> st [, <float> scale])
#ifndef FNC_SQTILE
#define FNC_SQTILE
vec4 sqTile(vec2 st) { return vec4(fract(st), floor(st)); }
vec4 sqTile(vec2 st, float scale) { return sqTile(st * scale); }
#endif
Use:
<float4> hexTile(<float2> st [, <float> scale])
#ifndef FNC_SQTILE
#define FNC_SQTILE
float4 sqTile(float2 st) { return float4(frac(st), floor(st)); }
float4 sqTile(float2 st, float scale) { return sqTile(st * scale); }
