Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UE4 PBS에서 IBL - Environment BRDF 2D LUT

안녕하세요. Siggraph 2013의 Real Shading in Unreal Engine4를 보면서 공부하는 중인데요. IBL에서 Environment BRDF의 정보를 2D LUT로 저장 후 사용하는 부분에서 궁금한게 생겨서 질문합니다.

Figure 3를 보면 2D LUT 좌측에 Roughness, 하단에 cosθv라고 적혀있는데 이것만 보면 Left, Bottom이 (0,0)인 그래프가 맞는 건가요...? 텍스쳐 좌표계랑 헷갈려서요. 저 2D LUT가 Left,Bottom이 (0,0)이 맞다면 뒤집어서 텍스쳐 좌표계랑 맞춘 후 써야 되는 것 아닌가요.
