Drawing a curved shape - 2nd attempt

Yes. I do use alpha mask images to fake it. But real live interaction is problematic. I need 3D control (at least of flat images). I need real curves under dynamic code control. I need object hinging and linking inheritance. I need the y axis. I need speed! I need threading! And yes i have rolled my own in all of these cases. But my god things slow to a crawl! How about edge detection (as an official property? How about gravity? Acceleration? Compression? Spring? Viscosity? Lighting? Surface effects? Built in versioning? Built in history? Topography? I know, i know, i am asking for tooooooooo much. But a guy can dream. What we have as a starting point is a great language. Object code and an event driven message triggered behavior model. That is a very good place to start.

This is true, but then again, how many xtalk environments are flourishing
these days? If one wants to do do slick graphics, an xtalk is not the first
place they'll turn. It's Flash or something similar. Revolution only
recently got antialiasing, and even that doesn't work quite right. But it's

IMO, the key features you need to create the above are 1) alpha
transparency, and 2) gradient support, both of which are now available in
Rev. Ignoring those, PNG support has been strong in Rev for a while now --
the image object is your friend. Create PNG images in the image editor of
your choice and import. In my case, if it wasn't for PNG support, I doubt
there would much reason for me to use Rev at all.
But to your point, better graphic support will be key, and soon, given the
promises of Microsoft and Apple to move toward resolution independence and
scalable vector driven graphics systems.
