Also, the term "Nurbs" is being dragged around the net and destroyed. Poser definately does not need Non-Uniformed-B-Spline support. What it does need is Subdivision Surfaces support. Nurbs is building something out of mathimatical curves. Its used mostly in scientific and architectural modeling where exact meassurements are required. It also has a ton of topology problems that make using it for characters that need to animated difficult. It generally makes models that have far more polygons in low detail areas than needed, once its 'frozen'. Subdivision Surfaces is a technique that Pixar brought to the forefront for taking low resolution Polygon models and mathematically subdividing them to get a higher res, smoother mesh. It allows you to get all the benefits of freefrom polygon topology while getting the benefits of a smooth high resolution mesh like nurbs. Programs are running these terms through the wringer with all sorts of names and terms. (LightWave) MetaNurbs are actually SS, (3DSMax) has true Nurbs support and called their SS NURMs, (trueSpace) called their SS Nurbs in version 4; in version 5 they have since added real Nurbs support so are naming them appropriately. You get the picture. OBJ format created by Alias I believe (people who make Maya) : is one of the better formats for polygons that has been created; far better than 3DS imo. Models in OBJ format can be be used in a program that uses Subdivision Surfaces very well because its a format that can generate mesh based on quadrangles. Triangles in general don't SS well. The problem isn't the format is the crappy support in other programs out there for importing and exporting it imo.
