the app is amazing work about sculptgl HOT 16 CLOSED

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)

from sculptgl.

@disjukr color on vertex is ugly

from sculptgl.

@flufy3d but it dont need uv mapping.

from sculptgl.

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.

from sculptgl.

@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

from sculptgl.

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).

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.

from sculptgl.

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.

from sculptgl.

sounds great XD

from sculptgl.

done :D

from sculptgl.

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

from sculptgl.

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

from sculptgl.

seems I found a bug

from sculptgl.

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.

from sculptgl.

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