2.1、Hello world
- 新建一个文件 test.shader
- 里面写如下代码：
void main() {
float time = iGlobalTime * 1.0;
vec2 uv = (gl_FragCoord.xy / iResolution.xx - 0.5) * 8.0;
vec2 uv0 = uv;
float i0 = 1.0;
float i1 = 1.0;
float i2 = 1.0;
float i4 = 0.0;
for (int s = 0; s < 7; s++) {
vec2 r;
r = vec2(cos(uv.y * i0 - i4 + time / i1), sin(uv.x * i0 - i4 + time / i1)) / i2;
r += vec2(-r.y, r.x) * 0.3;
uv.xy += r;
i0 *= 1.93;
i1 *= 1.15;
i2 *= 1.7;
i4 += 0.05 + 0.1 * time * i1;
}
float r = sin(uv.x - time) * 0.5 + 0.5;
float b = sin(uv.y + time) * 0.5 + 0.5;
float g = sin((uv.x + uv.y + sin(time * 0.5)) * 0.5) * 0.5 + 0.5;
gl_FragColor = vec4(r, g, b, 1.0);
}
