You know, I plan them, and it does not have to happen. My school starts in mid-september and I also have my job , and I have planned to rest for a while, but anyway, here is the list of features that I have in my mind:
- Famous girl done by enkithan using sumi-e brush
* bidirectional painting — Emanuelle work could be involved
* brush shape defined by bitmap:
- bristles coordinates related to the center of bitmap or it could be selected in GUI somehow
- bristle length defined by brightness of the bitmap color (value from HSV color space)
I need to come up whether I use predefined brushes (brushop use them now) or I made own Gui for loading bitmap
* toXML, fromXML : export, import brush settings
* improve GUI: naming for 1D/2D, what to do with sigma?
* weighted saturation and opacity — i need to come up with clever formula
* Catmull-Rom curves used for path of the bristle (lines used now — some artifact happen)
* mixing of the bristle colors
* scale of the brush
What I would love to see, but it is quite harder:
* physics for bristles
* springiness for bristles
* TZander talked about brush properties to scale with the ppi of the canvas on our IRC (irc.freenode.net -> #koffice)
What do you miss in Sumi-e ? Let me know through comments…
Hey Lukas,
Great work on the SoC! The Sumi-E is really cool. What I miss; painting incrementally doesn’t seem to work. Other than that I can’t say I miss anything specific. The bristle strokes look a little coarse for me, maybe even non-antialiased, but I’m guessing that will be fixed. (http://dose.se/stroke.png shows what I mean).
Hi Elvis, thanks for comment.
I will fix that anti-aliasing problem. You can get better results with tablet and using 2D brush in settings dialog.
But I will fix that also for 1D brush.Problem here is that the path of the bristle is generated by poor line algorithm with no sub-pixel precision…More commits to follow!
Ah alright. That’s great.
