The wormhole towards other dimension of non-pov world is here if you
decomment the second line:
/******************************/
#declare Passage=9999999.0;
//#declare Passage=9999999.00002;
sphere { 0, Passage
pigment{rgb<0,.5,1>}
}
camera {
location <0, 0,-1>
look_at <0, 0, 0>
right x*image_width/image_height
}
light_source{0,2}
/***********************************/
Thanks Martial
And found by Mael (mlPOV) in the frame.h file of the sources:
/*
* These values determine the minumum and maximum distances
* that qualify as ray-object intersections.
*/
#define Small_Tolerance 0.001
#define Max_Distance 1.0e7
