2011.02.14 實在是..........太棒啦﹨(╯▽╰)∕ LeMans 24, Fighting Vipers 2, and Star Wars Trilogy Since the last update, I've been spending a lot of time looking at lighting and texture modulation in Scud Race. I've figured out some important things but there are still more questions than answers. Overall, various shading effects look better than they did before, and the changes have also generally benefited Sega Rally 2 and Virtual On 2. Elsewhere, they may be causing problems. I've also discovered the source of some of the missing geometry in Scud Race. The tiki head and staircases on the mountain course, the ship on the beginner course, and the circular tower on the night course are all visible now. http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_07.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_06.png have a better understanding of the source of some annoying graphical glitches in Sega Rally 2 relating to polygon RAM. I'm not yet sure how to fix them but similar problems are also showing up in some other games I added over the weekend, so now that I have more data to compare against, I'm hoping that a precise solution will become apparent. http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_08.png added Le Mans 24 and got it up and running. It is very playable but suffers from some graphical problems that I suspect are related to polygon color and fog modulation. http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_00.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_01.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_02.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_03.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_04.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_05.png So far, Le Mans 24 holds the dubious distinction of being the ugliest Model 3 game. It appears to have been released after Scud Race and features many of the same vehicles, making its sub-par quality all the more noticeable. It would have made an average-looking Model 2 game. Today, I hooked up Fighting Vipers 2. It runs pretty well on the whole but it appears to be referencing objects in VROM that are not actually models. The result is that very large polygons are sent to my renderer, dramatically slowing the game down. This is loosely related to some issues I've encountered in Virtual On 2 during boot-up and Sega Rally 2. http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_09.png http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_10.png Star Wars Trilogy mostly looks nice but I haven't spent very much time playing with it. I'll return to it later down the road. http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_11.png And last, but certainly not least: about those lighting effects I mentioned at the beginning... http://i20.photobucket.com/albums/b244/trzy/WIP_Feb13_12.png Look closely at where the vehicle is hitting the wall. See the pale yellow circle? My top priority right now is to figure out the Model 3's spotlight effect. The devil's in the details ______________________________________________________________________________ 來源：http://www.mameworld.info/ubbthreads/showflat.php?Number=246490 ※ 引述《conpo (びんぼうがみ)》之銘言： : 2011.01.30 : ﹨(╯▽╰)∕﹨(╯▽╰)∕﹨(╯▽╰)∕ : I added Virtual On and Lost World to Supermodel. Both boot up and run : just fine but for some reason, many textures are missing. I don't recall : having encountered this problem when we were working on the original : Supermodel... It's got me quite stumped so I think I'll move on to other : games and 2D graphics next. Maybe something will eventually click. For : now, here are some videos of Virtual On, which runs quite well, except : for the un-textured robots. : Virtual On : https://www.youtube.com/watch?v=79liu1RFgzI : The Lost World : https://www.youtube.com/watch?v=Sd0RPwFE6GM : Also, the last time I posted Scud Race videos, someone was kind enough : to volunteer recording some high quality videos of an actual Scud Race : machine for comparison. This is extremely useful to me. : If anyone is able to provide reasonable quality videos or even screenshots : of Model 3 games, please let me know. At the moment, I'm particularly : interested in understanding a certain effect in Lost World. If you think : you can help, send me a private message or an email. : ______________________________________________________________________________ : 來源：http://0rz.tw/zkX1b --
