Hi everyone,
I've tried osgspotlight example and it works fine. I've generated
*only*seven texture coordinates by using osg::TexGen and rendered the
spotlight
effects by fragment shader. But, I want to render multiple spotlight effects
in my scene (for example 20 spotlight effects).
*
void main(void)
{
vec4 sceneColor = texture2D(baseTexture,gl_TexCoord[0].xy);
vec4 spotColor1 = texture2DProj(spotTexture1, gl_TexCoord[1]);
vec4 spotColor2 = texture2DProj(spotTexture2, gl_TexCoord[2]);
vec4 spotColor3 = texture2DProj(spotTexture3, gl_TexCoord[3]);
vec4 spotColor4 = texture2DProj(spotTexture4, gl_TexCoord[4]);
vec4 spotColor5 = texture2DProj(spotTexture5, gl_TexCoord[5]);
vec4 spotColor6 = texture2DProj(spotTexture6, gl_TexCoord[6]);
vec4 spotColor7 = texture2DProj(spotTexture7, gl_TexCoord[7]);
vec3 spotColor = spotColor1.rgb + spotColor2.rgb + spotColor3.rgb +
spotColor4.rgb + spotColor5.rgb + spotColor6.rgb + spotColor7.rgb;
vec4 color = sceneColor * gl_LightSource[0].ambient;
float spotMapIntensity = 1 - gl_LightSource[0].diffuse.g / 3;
gl_FragColor = vec4(sceneColor.rgb * spotColor.rgb, 1.0) *
spotMapIntensity + color;
}*
Is there any suggestion about this subject? How about *deferred lighting*method?
Thanks.
Selman
