Hi Community,
I am seeing in the default fragment shader (snippet bellow) that a fog is
used into account but for some reason I can not make it work. Any hints for
the Fog settings?
Thanks a lot
#if FRAGMENT_SHADERS_ONLY
_mainFragmentShader = new osg::Shader( osg::Shader::FRAGMENT,
" // following expressions are auto modified - do not change
them: \n"
" // gl_TexCoord[0] 0 - can be subsituted with other
index \n"
" \n"
"float DynamicShadow(
); \n"
" \n"
"uniform sampler2D
baseTexture; \n"
" \n"
"void
main(void) \n"
"{ \n"
" vec4 colorAmbientEmissive =
gl_FrontLightModelProduct.sceneColor; \n"
// " // Add ambient from Light of index =
0 \n"
// " colorAmbientEmissive +=
gl_FrontLightProduct[0].ambient; \n"
" vec4 color = texture2D( baseTexture, gl_TexCoord[0].xy
); \n"
" color *= mix( colorAmbientEmissive, gl_Color, DynamicShadow()
); \n"
#if DISPLAY_SHADOW_TEXEL_TO_PIXEL_ERROR
" color.xy = abs( dFdy( gl_TexCoord[1].xy / gl_TexCoord[1].w ) )*
1024.0; \n"
" color.z = color.y; \n"
" color.x = color.z; \n"
" color.y = color.z; \n"
" color.a = 1.0; \n"
#endif
// " float fog = clamp((gl_Fog.end - gl_FogFragCoord)*gl_Fog.scale,
0.,1.);\n"
// " color.rgb = mix( gl_Fog.color.rgb, color.rgb, fog
); \n"
" gl_FragColor =
color; \n"
"} \n" );
