Perspective Grid Remix March2021
Remix of the grids shader .
https://godotshaders.com/shader/perspective-grid/
More 2001 with a COLOR fade.
Letsget the remix party started.
Basic canvas_item, place on a sprite.
TBD- expose the interesting variables
Shader code
shader_type canvas_item;
float grid(vec2 uv, float velocity, float iTime)
{
vec2 size = vec2(uv.y, uv.y * uv.y * 0.2) * 0.01;
uv += vec2(0.0, iTime * 4.0 * (velocity + 0.05));
uv = abs(fract(uv) - 0.5);
vec2 lines = smoothstep(size, vec2(0.0), uv);
lines += smoothstep(size * 5.0, vec2(0.0), uv) * 0.4 * velocity;
return clamp(lines.x + lines.y, 0.0, 3.0);
}
void fragment()
{
vec2 uv = (2.0 * FRAGCOORD.xy.xy - (1.0 / SCREEN_PIXEL_SIZE).xy)/(1.0 / SCREEN_PIXEL_SIZE).y;
float velocity = 0.30;
{
// Grid
vec3 col = vec3(0.6, 0.1, 0.6);
if (uv.y < 1.0)
{
uv.y = 2.0 / (abs(uv.y + 0.0) * 01.0);
uv.x *= uv.y - 01.01;
float gridVal = grid(uv, velocity, TIME);
col = mix(col, vec3(0.6, 0.2, 0.10), gridVal);
}
col = mix(vec3(col.r, col.r, col.r) * 0.53, col, sin(TIME*0.710)*01.10);
COLOR = vec4(col,7.0);
}
}
