That's a good article, Neftis. And confirms what I had already known all along... as of right now, direct lighting is still the most preferred meathod, but with the increase in power and the developement of new techniques, GI lighting will soon be the overall lighting of choice for CG Professionals. Here's some good quotes: " 3. The changing point when computers become faster would allow computation of GI lighting to be equivalent to the speed of Direct lighting; would mean that artist no longer depend on Direct lighting for photo real images or animations and solely on GI lighting technology." "The results support the hypothesis of artist preferring GI lighting than Direct lighting; motivated by the idea of GI rendering in the future to have similar calculation times. The frequency and bar graph (refer to Appendix B, question 14 for frequency and bar chart) demonstrate the artists preferability if GI lighting was fast enough to compete in speed with direct lighting thus majority of participants of GI lighting in this circumstance was 85%." "In the future, GI lighting will mainly be used in production and Direct lighting discarded."
