[osg-users] Custom Vertex Shader with Parallel Split Shadow Maps

[Julien Valentin]

Hi,

After a long time here's our answer:


Code:

vec4 pos=ftransform();
vec3  ecPosition3 = pos.xyz / pos.w;                       
vec4  ecPosition=vec4(ecPosition3,1); 
gl_TexCoord[1].s = dot( ecPosition, gl_EyePlaneS[1] );     
gl_TexCoord[1].t = dot( ecPosition, gl_EyePlaneT[1] );     
gl_TexCoord[1].p = dot( ecPosition, gl_EyePlaneR[1] );    
gl_TexCoord[1].q = dot( ecPosition, gl_EyePlaneQ[1] );      



cf osgShadow/StandardShadowMap.cpp

Cheers,
Julien
