Description
At paper, global significance calcuation is shown below.
In the code, I found this one at calculate_v_imp_score.
From what I understand, this method returns Global Significance score, and line 126 represents expression (4). Therefore, I reckon imp_list must be remaining parts of expression (3) (as i highligted as yellow).
By tracking imp_list, I found imp_list is calculated at compress_diff_rasterization submodule, renderCUDA_count in forward.cu
At line 473, I guess collected_id[j] may represent light-intersecting function 1(G(Xj), ri), con_o.w may represent opacity σj. As function1() returns only 1 and 0, there is no need additional multiplying action. But I couldn't find where Transmittance is multiplied. T is calculated at line 467 though.
Am I missing some other parts or is this code deprecated? I am not even sure if I understood code correctly... I checked all the other cuda codes, but still not sure about it.
