Int / Floor
Create a shader program that generates a gradient image using an array of 5 colors. The colors are defined in the following array:
vec3 palette[5] = vec3[5]
(
vec3(1.0, 0.0, 0.0),
vec3(0.0, 1.0, 0.0),
vec3(0.0, 0.0, 1.0),
vec3(1.0, 1.0, 0.0),
vec3(0.0, 0.0, 0.0)
);
The program should determine which color range the current pixel falls within and interpolate its color accordingly. This will result in a smooth gradient transition between the colors in the array.
Hint
uniform vec2 iResolution;
vec3 palette[5] = vec3[5] (
vec3(1.0, 0.0, 0.0),
vec3(0.0, 1.0, 0.0),
vec3(0.0, 0.0, 1.0),
vec3(1.0, 1.0, 0.0),
vec3(0.0, 0.0, 0.0)
);
void main() {
vec2 uv = gl_FragCoord.xy / iResolution.xy;
gl_FragColor = vec4(0.0, 0.0, 0.0, 1.0);
}
