Does anyone know what kind of textures Imagine does support. Does it have marble?, Wood?, Wave? Clouds? etc. Can it do bump mapping (modifying the normal vector)? Is it possible to create your own textures (in assembler or C) as in TS? What I really would want is textures as in DKBTrace. It is realy awesome what you can do with textures in DKB (for instance have a look at the DKB roman scene with marble pillars under a blue sky with a few grey clouds). Helge E. Rasmussen .

No. Actually, I don't know what bump mapping is (I'm so ignorant, it hurts. Somebody please explain to me what bump mapping is, please?! --I'm serious). The only thing that _sounds_ like bump mapping (I'm getting into deep water now) which Imagine can do it calls "Altitude mapping" using brushes. This feature will be in 1.0 >Is it possible to create your own textures (in assembler or C) as in >TS? They provide no documentation on this in 0.9 but I'd be surprised if they left it out of 1.0 considering that Turbo Silver had this ability. Why should they regress? >What I really would want is textures as in DKBTrace. It is realy awesome >what you can do with textures in DKB (for instance have a look at the >DKB roman scene with marble pillars under a blue sky with a few grey clouds). I haven't seen this picture (would you mail it to me?) but Imagine (at least in v1.0) will be able to map a brush to the world. Not knowing any more about this, I'd imagine (pun intended) that you could simulate a cloudy sky and mountains at the horizon this way ... I may be wrong. >Helge E. Rasmussen .

A slip of paper packed with the software says "We will supply you with several new textures in the next release (1.0). Your old Turbo textures will not work so don't try and use them." >Does it have marble?, Wood?, Wave? Clouds? etc. Since marble and wood were included textures with Turbo Silver SV (the upgrade version of Turbo Silver 3.0) I can only presume they will be included with the Imagine 1.0 upgrade (which all Imagine 0.9 owners will receive automatically). The slip of paper packed with Imagine 0.9 doesn't list exactly which textures there will be with 1.0. > >Can it do bump mapping (modifying the normal vector)? > "Elevation mapping" is promised for 1.0. >Is it possible to create your own textures (in assembler or C) as in >TS? > Nothing was included with Imagine 0.9 to indicate yes or no. Did you ever see any user-created Turbo Silver SV format textures? Or did you ever try to create any yourself? The ONLY TS or TS-SV textures I've seen are the ones provided by Impulse with their programs. I was hoping by now some user-created ones would've sprung forth from the shadows but I guess not. > >What I really would want is textures as in DKBTrace.

I admire people who can create artwork that impressive without the benefit of a graphical user interface in which to do it! Harv Laser {anywhere}!crash!hrlaser "Park and lock it. Not responsible."

This >feature will be in 1.0 As is stated above, bump mapping involves perturbing the surface normal of an object before it is used in the illumination model. This creates the illusion of a rough or textured surface without adding polygons. Frequently, the bump or displacement map is an image in which the intensity of each pixel indicates the degree of displacement for that point on the surface. This sounds a lot like the above mentioned "altitude mapping" with brushes. +--------------------------------------------------------------------------+ | Mark Thompson | | mark@westford.ccur.com | | ...!{decvax,uunet}!masscomp!mark Designing high performance graphics | | (508)392-2480 engines today for a better tomorrow. | +------------------------------------------------------------------------- +
