Shader crashes JVM

Posted by cubus on Mar 19, 2013; 12:23am

hi,

this fragment shader crashes the jvm... when running the shader on GLSL Sandbox, everything works.

if either LINE C or LINE D are uncommented it crashes.
if then either
      in LINE A the "2.0 + 1.0" is changed to "2.0 + aValueThatIsNot 1.0" (eg "2.0 + 1.0001")  
or  
      LINE B is removed
then it works

btw, i know that the
                float my = resolution.y;
                if (y <= my) {
does not make sense, this is just a broken down version to have a crashing code ;)

any ideas?



#ifdef GL_ES
precision mediump float;
#endif

uniform vec2 resolution;
uniform vec2 mouse;
uniform float time;

void main(void) {
        vec2 p = 2.0 * (gl_FragCoord.xy / resolution.xy) - 1.0;
        p.x *= resolution.x / resolution.y;

        float r = 0.0;
        float g = 0.0;
        float b = 0.0;
       
        const float ni = 9.0;
        float cw = resolution.x / (ni + 1.0);
        float ch = 2.0;
       
        float x = gl_FragCoord.x;
        float y = gl_FragCoord.y;
       
        for (float i = 1.0; i <= ni; i += 1.0) {
                float cx = i * cw + cw / 2.0;
                float dx = x - cx;
                float my = resolution.y;
                if (y <= my) {
                        float dy = my / resolution.y;
                        float yy = y / resolution.y;
                        float ww = (cw / 2.0 - abs(dx)) * 0.1;
                        float wmul = abs(sin((p.y * 2.0 + 1.0) * ch));              // <<< LINE A
                        ww *= wmul;                                                           // <<< LINE B
                        float c = clamp(ww, 0.0, 1.0);
                        yy = clamp(yy, 0.0, 1.0);
// r += c * yy;                                                              // <<< LINE C
// g += c * (1.0 - yy);                                                   // <<< LINE D
                }
        }

        gl_FragColor = vec4(r, g, b, 1.0);
}
