Furnace

|

|
This test has the camera located inside a diffuse box with emittance 1
|
||
|
|
and albedo "a". The amount of illumination received by the camera should
|
||
|
|
be be the same in all directions and equal to
|
||
|
|
|
||
|
|
1 + a + a^2 + ... = 1 / (1-a)
|
||
|
|
|
||
|
|
The following tests this for both the direct_ems tracer and the MIS direct_ems
|
||
|
|
tracer, with two different values of "a".
