Methods

tile(sampler2D tex, vec2 tileSize)​

Gives new UV coordinates

Returns:

tileSize = vec2(360) - (tileSize - 1);

float verticalTiles = textureSize(tex, 0).x / tileSize.x;
float horizontalTiles = textureSize(tex, 0).y / tileSize.y;
vec2 tile = vec2(floor(verticalTiles * uv.x), floor(horizontalTiles * uv.y));
vec2 tileUV = vec2(fract(verticalTiles * uv.x), fract(horizontalTiles * uv.y));
float xResult;
if (tile.x == 0.0) {
    xResult = tileUV.x / 3.0f;
} else if (tile.x == verticalTiles - 1.0) {
    xResult = tileUV.x / 3.0 + (2.0 / 3.0);
} else {
    xResult = tileUV.x / 3.0 + (1.0 / 3.0);
}
float yResult;
if (tile.y == 0.0) {
    yResult = tileUV.y / 3.0f;
} else if (tile.y == horizontalTiles - 1.0) {
    yResult = tileUV.y / 3.0 + (2.0 / 3.0);
} else {
    yResult = tileUV.y / 3.0 + (1.0 / 3.0);
}

return vec2(xResult, yResult);

Return Type: vec2
