Question

我想知道是否有任何方法可以将过滤器的glsl代码转换为RenderScript。使用此RenderScript处理我的bitmap字节。

例如：

precision highp float;

uniform vec3                iResolution;
uniform float               iGlobalTime;
uniform sampler2D           iChannel0;
varying vec2                texCoord;

float rng2(vec2 seed)
{
    return fract(sin(dot(seed * floor(iGlobalTime * 12.), vec2(127.1,311.7))) * 43758.5453123);
}

float rng(float seed)
{
    return rng2(vec2(seed, 1.0));
}

void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    vec2 uv = fragCoord.xy;
    vec2 blockS = floor(uv * vec2(24., 9.));
    vec2 blockL = floor(uv * vec2(8., 4.));

    float r = rng2(uv);
    vec3 noise = (vec3(r, 1. - r, r / 2. + 0.5) * 1.0 - 2.0) * 0.08;

    float lineNoise = pow(rng2(blockS), 8.0) * pow(rng2(blockL), 3.0) - pow(rng(7.2341), 17.0) * 2.;

    vec4 col1 = texture2D(iChannel0, uv);
    vec4 col2 = texture2D(iChannel0, uv + vec2(lineNoise * 0.05 * rng(5.0), 0));
    vec4 col3 = texture2D(iChannel0, uv - vec2(lineNoise * 0.05 * rng(31.0), 0));

    fragColor = vec4(vec3(col1.x, col2.y, col3.z) + noise, 1.0);
}

void main() {
    mainImage(gl_FragColor, texCoord);
}

我想将此过滤器应用于bitmap。任何人都可以帮助我入门，我将非常感谢
