the app is amazing work

[flufy3d]

hope there could be a cooler ui. data gui only a demo way
and feature like image project painting
could i help you anything?

[stephomi]

For all the painting stuff I will need texture coordinates... and UV mapping is not an easy problem :(

I also wish for a better interface ( I think there is a bug with it in the lower left area of the screen).
And the combo boxes aren't not really user friendly.
I don't know if there's a good alternative for dat.gui, maybe tweaking the css might be enough (but I'm bad at the css stuffs).

@stephomi then.. how are you thinking about painting the color on vertex color property? (maybe need to modify shader)

[flufy3d]

@disjukr color on vertex is ugly

[disjukr]

@flufy3d but it dont need uv mapping.

[stephomi]

I already thought about that, it would be easy but ugly...

It would be great to have UVs... but as sculptris and blender do, I should then prevent the decimation and subdivision process (well in theory it would be possible to assign new uv coordinates to the newly created vertices but that's another problem).

There're some softwares that are only dedicated to UV mapping... so I don't think I'll find a magic javascript library on UV unwrap :D.

[flufy3d]

@stephomi dedicated UV mapping softwares such as？

are there any open source UV mapping softwares ?

the zbrush's uv mapping tool is very cool ,but its Commercial

[stephomi]

This one or this one, but they are commercial.

As for open source project... there're CGAL, blender... and maybe wings3d and other softwares .

The best uv tools are not completely automatic and the artists usually just have to give a few hint ("cut here", "want more pixel on this area"...)
An automatic uvmapping that produce patches such as in sculptris would be fine enough, but that's quite a challenge (on top of doing it in Javascript).

[disjukr]

I think painting color on vertex is maybe not so much ugly then you guys thinking..
because sculpted model is usually have high poly then texture map resolution.
and also zbrush support it.
I think offering conversion between vertex color and texture map later then uv mapping is enough to user.

[stephomi]

Hmmm maybe u're right, I'll give it a try when i'll have time.

The shader should be very simple, integration with the subdivision/decimation process will also be easy, and there's also the history (undo/redo) that shouldn't pose any problems.

[disjukr]

sounds great XD

[stephomi]

done :D

[flufy3d]

@stephomi cool, the vertex color painting is done ,Very efficient！:D

[DreadKnight]

Nice! Is there a colorpicker functionality right from the model?

[flufy3d]

seems I found a bug

[stephomi]

Dat.gui color picker is broken...
I really want to change the interface but I'm a bit afraid to dive in HTML/CSS stuff.

For the color problem I guess I can fix it easily as someone already experienced the same kind of bug for the color picking (and gave me an hint on how to fix it).

For the model color picker, if you mean click on the model and pick the color under the mouse, that shouldn't be difficult either.

[flufy3d]

the color problem is difficult to reappear.....
