we try to use embree engine, it's very fast and clear. We use xml method
to export the scene.
But we find some problem with light and material.
Why the source code don't use Ka parameter of
material? there is some part of source code that calculate automatically the
(Ka) ambient parameter of material? It seems that is used only a factor Kd, and not Ka & Kd , it's
The scene is very dark in parts distant from
the light and very bright in
places near the light, there seems to be a lot of contrast caused by an ambient
factor of the material is too low.
It seems that instead with hdrilight work better and
the light is spread more evenly.
But unfortunately 99% of our scenes are
indoor and we use pointlight and spotlight.
Can you help us to resolve this problem?
Probably the same problem, but let's see if we put a pointlight the distance of the light emitted is low, we must greatly
increase the intensity but then
we always have a great contrast between the places near the light and places distant the
cannot calibrate well materials
and lights so that light is spread evenly
in the scene, can you help us for this?
example of wall material parameter is:
0.5882 0.5882 0.5882
0.6882 0.6882 0.6882
0.0000 0.0000 0.0000
