Hi Kim,
Still i"m getting the glare effect, this is my fragment shader..
//
varying vec3 v_V;
varying vec3 v_N;
uniform bool osgOcean_EnableGlare;
void main() {
vec3 N = normalize(v_N);
vec3 V = normalize(v_V);
vec3 R = reflect(V, N);
vec3 L = normalize(vec3(gl_LightSource[0].position));
//vec4 ambient = gl_FrontMaterial.ambient;
//vec4 diffuse = gl_FrontMaterial.diffuse * max(dot(L, N), 0.0);
//vec4 specular = gl_FrontMaterial.specular * pow(max(dot(R, L), 2.0),
gl_FrontMaterial.shininess);
//gl_FragColor = ambient + diffuse - specular;
if(osgOcean_EnableGlare)
{
gl_FragData[1] = vec4(0.0);
}
gl_FragData[0] = vec4(1.0,0.0,0.0,1.0);
}
//
Am i missing something?.
Regards,
