Katarhyne Posted June 19, 2001 What about EMBM, DOT3, vertex and pixel shaders - all of that phat nastiness? Have we any information on what D3 will be using and what it won't be using? * Katarhyne muses on the fact that she's the only person in the forum who will be able to run Doom III and decides to brag about it in the D3 forum. Mwahahaha. ---- Oh, and for all the rest of you morons, has anyone considered making a Doom III-ish level in, say, ZdoomGL or Vavoom or Legacy? 0 Share this post Link to post
kain Posted June 19, 2001 um... yah right even if you did have the softeware for it now, it will be obsolete in 2 years. so ha ha ha ha ha to you bia bia bia!! 0 Share this post Link to post
Dima Posted June 19, 2001 I am not Zaldron, but I know one :) Anyway, the features you described will indeed be supported in the new doom game (EMBM won't be). You can watch the MacWorld movie and see examples of them: Characters expressions - vertex shaders. Lighting - pixel shaders. Floor, enviroments, etc - DOT 3 Bumpmapping. If you'd like more info, just ask =) 0 Share this post Link to post
Zaldron Posted June 20, 2001 Katarhyne. I don't think id will use Enviromental Bump Mapping in this game, since they can archieve better effects using Pixel Shaders and DOT3. Vertex shaders will be used for 2 reasons. They give you hardware accelerated functions specifically designed to distort meshes, wich is the key concept while animating models. Walking, running, shooting, waving arms, talking and head turning will be now calculated in the video card, freeing your CPU. Besides, Vertex Shaders give you the same advantages that T&L (thank God, cause it doesn't work while VS are running). DOOM just needs the "T" part of T&L, since gourad shading (commonly called vertex shading) has been ditched. The transform routines to precalculate the world are much needed because of a matter of polycounts. Pixel shaders are on too. Just take a look at the video. The traditional lightmapping and vertex shading has been replaced with "true" lighting systems. In order to adjust the brightness of every visible point of the world (the pixels in your screen), pixel shaders are called to process the lights distance/occlusion over every surface. DOT3's used to enhance the looks of every texture in the world. Skins and world textures are joined with a special grayscale image that represents the respective heightmap. 0 Share this post Link to post
Dima Posted June 20, 2001 Zaldron EMBM won't be used 100%. I remember Carmack saying in Voodoo Extreme's interview that EMBM "just doesn't cut it". In other words, DOT 3 BUMPMAPPING is the only technique of bumpmapping that allows Carmack to realise his dreams. 0 Share this post Link to post
Zaldron Posted June 20, 2001 More proof that the GF2 will be an awful solution if you wanna play DOOM. 0 Share this post Link to post
Dark Fox Posted June 20, 2001 Well fuck.. I just bought a G2Ultra Zal, you had to say that? 0 Share this post Link to post
Dima Posted June 20, 2001 Buying a GeForce 2 Ultra right now was a very stupid thing to do! 0 Share this post Link to post
Dima Posted June 20, 2001 BTW Zaldron, EMBM is not supported by GeForce 2 series of cards. 0 Share this post Link to post
Zaldron Posted June 21, 2001 And I never said they were, but there's a lot of difference between horsepower needed between EBM and DOT3. 0 Share this post Link to post
LorD BaZTArD Posted June 22, 2001 I gotta ask, Since My New Machine Will be mine by the end of Next Week.... I have a Video Card Question If I Do what I plan to Do and wait 6 Months to get a Geforce 3, what should I get instead. GeForce HighEnd Obselete In 6 Month ULTRA ---------------------OR------------------ GeForce LowEnd Already Obsolete But Works Until GeForce 3 is Cheaper MX A more Serious Example would be: GeForce 2 Ultra 64MB DDR Ram With T&L High Clock speed And More......... ---------------------OR------------------- GeForce 2 Mx 32MB SDRAM With No Features But Ok Clock Speed And Less........ (Just In Case You Didn't pick it... the names are not exactly serious) 0 Share this post Link to post
