Seamless

Very Sorry Isa and Alain, for some reason I have not been getting automatic updates from this thread lately this is the first time I have seen the last 7 posts here

Thanks very much Alain for explaining the color sweep I am indebted to you.

And Isa too for your experimentation what an original pretty looking flower !

LOL Alain yes this how all maps are printed in Australia

This may seem odd to you in France but in Australia it feels totally natural to wear your shoes on your head and to hop with your feet in a hat

Radial Tug Extended to NURBS Control Points for 2.150

Open Source Seamless3d 2.150 can be downloaded from:

http://www.seamless3d.com/download

For 2.150 I have extended the Immediate radial tug (that was announce for Version 2.120 in May 2007) to nurbs control points:


By thymefromti

Now that seamless supports nurbs modelling perhaps its a logical conclusion but when I first had this idea it sounded a bit silly to me because aren't nurbs an alternative to using radial tugs? Well not exactly. In the case of a realistic human face you need many control points to define it and so it can be very useful to be able to tug multiple control points at a time and have the amount each control point is tugged within a specified radius vary depending on how close they are to the center of the tug so that there is always a smooth transition to the unaffected control points.

To use the radial tug first select the NurbsPatch in the scene tree window and establish a radius by clicking up on this button: from the toolbar.

When the radius is visible you can also resize the radius by dragging the control point located to the right on the radius (the red dot located on the cyan colored circle)

The following screenshots show how no more than 2 radial tugs can dramatically alter Lucy's face:

H-Anim Import & Browser Avatar Compatibility Test Updated for 2.151




Open Source Seamless3d 2.151 can be downloaded from:

http://www.seamless3d.com/download

Seamless3d could import hanim a good many months ago but for lack of time in testing, this is the first formal announcement. Also improvements have been made over time including this last week.

To show how to import hanim I have written a tutorial that has evolved from Nontiti's tutorial he wrote in Japanese.

I have updated the browser test page, it now uses Lucy as the example and it better demonstrates the advantages and disadvantages of using different options for different browsers.
All except one of the sub examples are exported without any hand editing to the source file to make them work for the various VRML/X3D browsers.
I would have liked to have tested Instant Player but it crashed for me after I installed it even when I do not try to open anything with it. Anyone used it for hanim?

Seamless3d is the only modeller I am aware of that can use hanim as an interchange format for both exporting and importing avatars. Thanks to the way Seamless3d natively indexes vertices for part ownership, there is no need to re-rig the model for further modelling. With Seamless3d, animated HAnim avatars can be imported and exported repeatedly without accumulating file bloat.

Single meshed h-anim models that use either an IndexedFaceSet or an IndexedTriangleSet node can be imported.

Nontiti has tested this feature on an avatar he made using Vivaty Studio and was able to use this avatar in Seamless chat and be able to export to use the setByVertexTransform so that it can play efficiently in Cortona. I have tested the import feature on Lucy exported a number of different ways and even got Seamless to import Joe D William's avatar he made using only a text editor. Being able to import this range of avatars without needing to hand edit the file suggests some robustness has been attained.

For 2.151 I have added a new export option outScriptAsRoutes.

This feature causes simple lines of script that have a ROUTE equivalent to be exported as ROUTEs instead of script.

ROUTEs allow for animations to be played by a greater range of VRML/X3D browsers, however this export setting will prevent more advanced scripting features such as "if statements" and math functions from being used for animation so don't use it for any scripts more complex than nodeB.field = nodeA.field

On a different note I have made it so that the chat log can easily be opened by right clicking on the chat window and selecting "open chat log"

Many thanks to nontiti for his help getting Vivaty Studio to export hanim models for Seamless3d and his Seamless3d & Vivaty Studio tutorials which have greatly helped me.

It is Saturday 20:GMT so I am available for chat in Seamless3d

Great !

Avatars are one of the key aspects in 3D multiuser and is really fantastic all the work you have done around them in seamless; creating, importing/exporting, animating and also around the h-anim standard.

I have tried to look in your site for a complete example of one mesh imported from Avatar Studio and animated with seamless, as you say in one of the tutorials. Can you point to some of them you imported from avs (or someone else) which includes a complete set of post animations in seamless?

thanks

Hi vcard and Thyme

I was playing with our dear Lucy , that morning ,

I wondered if she could be more sexy dressed ,
I must admit that the result is a bit crappy LOL

http://dumenieu.free.fr/louizeforum/seamless/lucy6_etpants4.wrl

but my way to still learn seamless

( more easy for Thyme to "answer" on seamless forum , vcard ,

if I could say ,

but we are all use to jump from friendly forums to others ,
so no matter

Thanks vcard

Its a good question you ask, links to hanim models online are a rare find and even rarer if they work and are legal.

All the avatars on my av page in smls format can be exported to H-Anim x3dv/z format and then should also be able to be imported back to smls format.

You wont however get back all the goodies that it exist in the original smls file such as the nurbs control points and because the original smls files use features like nurbs to generate the meshes, smls files are about half the size of the H-Anim files.

For some smls files online already exported to hanim I have 3 of Lucy (exported with different hanim options) on my avatar compatibility page:

http://www.seamless3d.com/browser_test/lucy_test0.x3dvz
http://www.seamless3d.com/browser_test/lucy_test2.x3dvz
http://www.seamless3d.com/browser_test/lucy_test4.x3dvz


The hand coded file made by Joe D Williams that I imported is located on his site:

http://www.hypermultimedia.com/acontents.htm

See there: X3D H-Anim Examples

I tested the first example:

H-Anim Example 0 .x3dv

Although I asked Joe D Wilaims if I can reference his avatar as an example I do not know if they are exactly open source like all my avatars are so you may need to check with him first if you want to modify them for online use.

I dont think nontiti's av he made with Vivaty studio will be online in H-Anim.

Hope this helps

best wishes

hi tutan

Good work Alain, yes good to play like this to get familiar with the features of the software. I am interested to know how you added the trousers
I showed your wrl to ep, we both agree it looks good how you made her underwear have a matching pattern, or at least the elusion of, very clever

LOL
by my stupid way I am used

after deleting many things in Lucy
from your tree ,
you could get the hips -legs

http://dumenieu.free.fr/louizeforum/seamless/hips.wrl

and changing it in a trouser

btw I am not the best teacher in seamless ,
because it needs more work to have a non static mesh

...
*blushing* that Ep saw that I am playing with trousers LOOOL

( hello Ep

so ....same way with a shirt

http://dumenieu.free.fr/louizeforum/seamless/lucy6_shirt.wrl



reedit

or


http://dumenieu.free.fr/louizeforum/seamless/lucy6_shirtzeb.wrl

The shirt looks great Alain You used a NurbsPatch for this?
and how did you apply the "I am not a zebulon" texture?

sorry for the delay

I used a piece picked in your tree ,
then converted to a blue node

and scaled

and the tecture with vrmlpad ,
as I saw the mapper is only for white nodes ,
if I am not wrong ..


may be you could add the mapper texture working for blue nodes

an other way for fun is to add a Nurb Lathe as clothe ,
ans then texturing it

Nice Dress Alain I will talk more about texture mapping later.

Miranda's Birthday 2009



Please join me, Miranda and other friends to celebrate Miranda's birthday in seamless chat .

For the occasion I have dusted off and restored Miranda's Famous Birthday Cake Ep made back in 2003 and which I animated the flowers

If you have not updated seamless chat in a few months you had better download the latest version from

http://www.seamless3d.com/download

It's faster than flash to install, you don't have to uninstall the old version first or anything complicated, just download and install.

The party will begin at :

19:00 GMT
9:00 PM Europe
3:00 PM New York

You can see where everyone is hanging out from this link:

http://www.seamless3d.com/worlds_open.php

But to join a world to chat you must open seamless (the modeller is used for chat) and click on the "open smls file from the web" button:



All are welcome at the party, hope to see you there

playing with Lucy , LOL

http://dumenieu.free.fr/louizeforum/seamless/lucypneu.wrl

dont ask me what it means , I have no idea
I just got the "project" from a movie I was watching

I wonder if fog and music makes all more "poetic" LOL

btw I saw that Chisel change the file from 205 ko to 45 ko ,
but broked a bit the colors ,
so ..
I had the idea to delete the colors then adding music

http://dumenieu.free.fr/vrml/zik/lucypneu_pavane.wrl

I hopr that works , it is mp3

I think both versions you made of Lucy swirling on the rope are mood provoking and very arty Alain
Seeing this reminds me how making movies could be a lot of fun.
I think movies can offer the artist a lot of artistic freedom in setting up the mood for the viewer that may not be possible in VR.
For example movies often make much use of what the camera shows, from what angle and the timing of the event plays an important role.
Even just the period a scene is played for is under the control of the artist and is utilized.
As with VR the lighting and fog effects can play a role in stirring emotions but ray tracing should allow even greater control over the end result
NURBS animation could also be better utilized for movies because you don't have to worry about the frame rate dropping below 24 FPS
What I like is the idea of making a controlled movie and making the movie props available to VR for chat.
Seamless3d's NSPE should make it relatively easy to optimize for both environments.

Thanks much for the screen shot of Miranda's Birthday Alain and for being there
This makes for a nice logo:

Here is a photo I took of Mikerman wearing the Seamless3d hopzog logo over the candle and Taranis's avatar to the left and Miranda to the right in red:



I like much this photo taken by Mikerman, It shows Dajamma wearing gamonbrat's pink fairy av and me after experiencing a lot of internet lag which resulted in a bad case of cloned spotted cat av



It was great to see Miranda and Mikerman again and the unexpected visits from Isa, Laz, Taranis and VCard

Many thanks to all

yesssssssssssssssssssss !!!

it is what I thought just after finishing my fog-music Lucy

but I have nothing good to make that and I was forgetting your PovRay way !


I retried it quickly ,


http://dumenieu.free.fr/vrml/zik/lucypneu.htm


hard to remember all after all these last months I didn't used it ,

but I had the help of your tutorial


Thanx Thyme , I think I will re try that nice movie way

now I must learnt how to add the sound in the movie

http://dumenieu.free.fr/vrml/zik/lucy_pneusmls2_movie.avi

indeed I got in in the smls file

http://dumenieu.free.fr/vrml/zik/lucy_pneusmls2.wrl

but I understand nothing about the Background
it stays black

LOL whats the Hell !

I followed your



but the song is more long than the animation ( that is loop )

so the animation stop after some minuets



where I am wrong ?,


btw I am lost too with the view point , I cant go closer the girl LOL


here is my last file


http://dumenieu.free.fr/vrml/zik/lucy_pneusmls22.smls


and here the results

http://dumenieu.free.fr/vrml/zik/lucy_pneusmls22_movie2.avi

Well done Alain
I see what you mean, when making a movie "loop" does not work.
However when generating frames for a movie you need to specify an exact number of frames and so an infinite loop may be impractical.

I would like to make it so you can copy a length of animation in the time frame and paste it anywhere else in the time frame. This should allow the user to repeat a number of cycles pretty fast for a movie without needing loop mode.

Here is a quick solution that will work now :
Keep the existing Anim node looping for the animation and add a new Anim node to the scene tree.
Set the new Anim node's period to the length you want the movie to last for
Right click on the new Anim node to generate the frames for the movie.

The old Anim node if left looping to animate the povray move for the period specified by the new Anim node.


Set anim2.period to the number of cycles times anim1.period


The following example will play 4 cycles:

Code:

DEF anim1 Anim{
   play TRUE
   pause FALSE
   loop TRUE
   period 4
   #interpolators and script as you left it
}
DEF anim2 Anim{
   period 16
}

Makes sense?

Ok I set your viewpoint to:

Code:

Viewpoint{
   perspective FALSE
   zoom 1.948717
   position -.391533 1.098554 3
}

To get close view of Lucy.

To do this, this is what I did.

1/ In the scene tree I deleted your viewpoint node.
2/ I pressed Esc to reset viewpoint to default position.
3/ I dragged on background to move Lucy (this really moves the viewpoint position) and used mouse wheel to zoom in
4/ dragged a new viewpoint in to capture the view.

You can re-capture a new view for the viewpoint node later if you click the Viewpoint node's "capture" button.

Tip: if you don't already have the viewpoint node selected, right click to select the viewpoint node so that you don't reset the view to the Viewpoint's fields before you have a chance to click the capture button.

Ok Alain I understand now sorry.
Seamless3d remembers the background color in the settings.
You can change the background color 2 ways.

You can open the F10 menu and select Settings and then change the backgroundColor field

of you can add a Background node to the scene node (look for black node with stars on it in the vertical new node bar)

When exporting to VRML you must have a Background node if you want to export the background color.

I see you already have a Background node Alain
Ok I dont know how a VRML Background node works eaither lol

LOL

the fact is that the wrl outputed

from

http://dumenieu.free.fr/vrml/zik/lucy_pneusmls22.smls


is

Code:

Background{
groundAngle 0
groundColor .1 .1 1
backUrl ""
bottomUrl ""
frontUrl ""
leftUrl ""
rightUrl ""
topUrl ""
skyAngle 0
skyColor .1 .1 .51
}

and it is black !

if I delete in vrmplad

Code:

backUrl ""
bottomUrl ""
frontUrl ""
leftUrl ""
rightUrl ""
topUrl ""

it is OK ...blue

...strange ..

btw I tried things for your previous answers ,

I will post tomorrow when time , scuse
