Re: The RSV6 Viewer ... and Texture Baking ... solved for SDS !
See if you can spot what I did to force the screen to render SDS properly in realtime . garry Ah, a riddle. Either fiddle with the texture quality and the mat. rendering (wire tab), or change the sds object from polygone to nurbs. What have I won? Frank Bueters Hmmm : Well , polygon to nurbs has no effect what-so-ever , so that tells me you are guessing . Fiddle ? Sorry , no prize ... yet . (but you are obviously very close) garry

Frank Bueters Hmmm : Well , polygon to nurbs has no effect what-so-ever , so that tells me you are guessing . Fiddle ? Sorry , no prize ... yet . (but you are obviously very close) garry fiddle because there are many combinations of texture quality and material rendering that may- or may not work. To mention a few: - texture quality none, mat. rendering full = black - texture quality none, mat. rendering single = illu map shows full - texture quality 1024, mat. rendering single = illu map shows greyish - texture quality 1024, mat. rendering full = black - texture quality 512, mat. rendering single = illu map shows full And many more... Polygon to nurbs does show the image map btw. this depends on the OS and/or video card perhaps. Frank Bueters
Re: The RSV6 Viewer ... and Texture Baking ... solved for SDS !
Seems to me that the SDS texture update is not working as exspected. Replace the image in the image object, rectangle is updated, SDS not. Switch the SDS in edit mode (Point or Face) then move the points...

Just did some quick tests and I was able to create maps for raytraced shadows that were displayed very well in OpenGL and the RSViewer . I think it possible to combine the illumination maps with the color maps in an image editor , to get a nice effective OGL representation . garry A very quick dirty example of 'Baked illumination maps' using the 'UVimage Tool' . Stock , non-postprocessed maps at 256 pixel resolutions and samples set at '5' . Sphere and rectangles are Analytic . garry Well done! How did you make it show up in OGL, any modifications in the mapping materials? All I get is black walls in realtime, only when rendering the mappings show up. I haven't tried baking in V6 with analytics yet, just an SDS 'Room' in a simple Building... must be overlooking something. cheers, Mark

Re: The RSV6 Viewer ... and Texture Baking - Reply #3
As I said earlier , previous versions of RS would do this for you , so I'm assuming we still can ... OK , great : The tutorial is still in the V6 manual . It's called - - Chapter 8. Rendering - - Advanced Illumination Examples The whole key is this very undocumented part of RS , parti- cularily - the 'UVimage Control' in the Material Menu .This is what I was searching for , and it is the beginning tool for creating illumination/color/shadow maps for OpenGL . Just did some quick tests and I was able to create maps for raytraced shadows that were displayed very well in OpenGL and the RSViewer . I think it possible to combine the illumination maps with the color maps in an image editor , to get a nice effective OGL representation . More experiments forthcoming . garry
Re: The RSV6 Viewer ... and Texture Baking - reply 1
You can bake all you want, it simply doesn't show up in OGL mode... Well , the obvious answer is to use any advanced maps as .bmp's . I guess that's why you lost me , since you already said you have done it for a ceiling . Ah, that was for a render, not realtime! Actually I was referring to these pics http://www.athanor3d.com/div/VIPGI03.jpg http://www.athanor3d.com/div/VIProom_livingroomGI04a.jpg GI renders, ceilings are pre-computed: baked indirect illumination (hand-tweaking was necessary, like you say later), and left out of the GI level to speed up rendering. They really need a crisp V6 re-render, there are some blur artifacts... some flowers would help too ;) [snip] Rembrandt was dutch , wasn't he ? Yes, like Van Gogh - born a few miles from where I live ;) Very cool , perhaps there's something in the water ? (grin) I hope not, he got crazy and shot himself through the head ;) I'll get back later: vistors, -Mark

Re: The RSV6 Viewer ... and Texture Baking
Hi Mark : Impressive stuff, smooth realtime movement and full GI. You don't see that often in realtime! I agree . Yes, it's worth a try with RS. Baking illumination can work well, I used this trick for ceilings in GI scenes. Exactly . But baking indirect illumination into an entire scene... Exactly ... (this is the key!) it should be possible, slowly building up complexity and mapping resolution. If necessary, edit some of the mappings manually . Well , that is a very , very deep subject , and an area that has not been explored yet in this tiny community . 'Unwrapping' a raytraced object's texture for Baking ? Is this even possible in any single 3D app available today ? I doubt it . Cutting edge RS offered options for 'Baking' illumination maps in V5 , but my quick look at this V6 manual did not find that tutorial . Is it still a V6 option ? So where do we start , to even discuss the workaround method ? As you say , edit manually , I guess , but man that is a lot of work (as I believe you are implying) . Matthias came up with that brilliant idea for using a chrome sphere to capture rays and make them available for 2D pano projections . Your (lost) example project upload showed it ! It's this kind of thinking that is required to take 'Baking' to the next level , I would guess . Of course, baking only works in static scenes where only the camera is moving, that's a disadvantage. Hmmm , I don't think so . Remember , the RS viewer allows for animation triggers ! So , as you can well imagine I'm sure , textures could _also be animated_ to contain the shadows that _should_ be cast from those animated objects ! What other _3D_ realtime viewer in the world allows for something as cool as that ? (none , I'm guessing) thanks for the links! Mark H check out the new ones at the top of this mail . garry
Re: The RSV6 Viewer ... and Texture Baking
Hi Mark : Big problem: RS's OGL realtime engine ignores the Illumination channel in VSL materials. How to make the illumaps show up in RS's own realtime engine? Is there a walkaround? All the more because shadows would have to be baked too, the RS engine doesn't do shadows, even though my graphics card does. Yes , at this point in time shadows would have to be 'baked' . Every- thing would have to be baked , except for whatever exceptions Vesa Juha would consider incorporating into the viewer in the future . I'd love to say RS can do great realtime walkthroughs with pre-baked illumination - would be great for architectural presentations - but no, it's all about rendering. Baking can still be very useful for rendering btw. (but tricky!) -Mark Hmmm , not sure I understand you on this point . Please elaborate . As you know , 'Baking' is the results of rendering ... ie , render once but view an infinite number of times . It's a fairly new concept and maybe there are some conflicting elements to be seperated first ? Anyway , it is a very intriguing option for animators , n'est pas ? Rembrandt was dutch , wasn't he ? (big grin) cheers garry

Cutting edge RS offered options for 'Baking' illumination maps in V5 , but my quick look at this V6 manual did not find that tutorial . Is it still a V6 option ? I don't see any changes. There is some info at the UVimage tool and the chapter Rendering/Advanced illumination examples. The word 'baking' isn't used in the manual.

It was a different principle (no baking involved) but the projects and textures are still at http://www.athanor3d.com/pub/ I think we need either complete export including textures and illumaps to run RS baked projects in an external advanced OGL viewer, or a better Realsoft OGL engine. -Mark

We probably need to call out to those who are more know- ledged in the arts of UV mapping . Is it possible to devise an unwrapping method (the rendered-post processed texture, not the UV mesh) with the tools or series of tools already available in V6 ? That's the question , and I'm still guessing the answer is going to take some deep considerations . garry
The RSV6 Viewer ... and Texture Baking
The new RSV6 Viewer has many possibilities of course . For ex- cellent examples of those possibilities we may have to look to some of the viewers which have been around for several years . http://www.studiodynamics.net/list/gallery.mpg 1.6 MB The above mpeg is a transcoded (via VLAN) example of, the below linked , online realtime viewer . http://www.digitalarts.dk/2004/06/art-gallery/ 17 real-time high-quality environments are available for viewing there via browser plugin (worked fine in NS9) , with the Art Gallery being one of the very early examples of 'texture baking' for RT viewing . Originally on http://www.suurland.com/ , there is also a version on the above digitalarts site that runs via .dll and is really very cool and fast . Complete with walking sounds . (6 MB download) http://www.digitalarts.dk/cases/gallery/art_gallery.zip Important info first about the .dll vesion . Disable the default 3D Colorcode , and try running it in a 1024 x 768 'Windowed' state first . Just arrow keys and mouse . Read the included help file , if required . Long mail , but in short , these examples may inspire to create examples of what _CAN_ be done with the new RSV6 viewer , with a little time and effort . http://www.videolan.org - plays and transcodes any video file you can throw at it (when you don't have the codec) studioattachment: ClipBoard.jpg
