With the ProPack, Poser now has an SDK. Although it has some limits it does expose a large portion of the scene to manipulation. While it cannot be used to change the rendering engine and some of the animation guts are inaccessible, code can (will) be written to do a number of the items on the wish lists above. Some of them will run quick and others will go overnight, depending on what you're trying to do. Collision detection, Gravity effects, subdivision and particles systems are all doable do's. The trick would be to get a number of them, like collisions, running fast under Python. Of course, there exists the option of compiling to native code and farming out some of the more intensive computations to a compiled Python extension lib. If/when CL exposes mouse, button and keyboard event callbacks to the python interface, then the sky would pretty much be the limit in terms of mesh modeling in poser. I invite Gecko and any other interested parties to post your wishlists over on the Python Scripting forum wish list. I, for one, will be looking at new projects once I get the !@#$%^&&*(()# Vicki 2 clothes pack debugged.
