control vertex help
Hi there all,
Before I got started with Maya, I first was thinking that spline patch model like in other 3d apps, are the same in Maya. But no it isn't. I realized buy finding what the definition of NURBS stands for, which stands for Nonuniform Rational B-Splines, and that b-splines work a little different. BTW please bare in mind with me as I will get to my question, though I need to explain where I am comming from.
So anywho, my background of modeling in previous years, I had tended a course in 3d modeling which I learned spline patch modeling with Animation Master, if any of you heard of that program. My point I am getting to is when spline modeling in Animation Master, the vertices are positioned on all 4 corners of each patch, just like how polygon vertices are layed out on each corner of their faces. However, when I have first opened up Maya, and tried editing a NURBS sphere primitive through control vertices, I notice that they look like they are wrapped around the object instead of positioned on each corner of their patch which doesn't really give me help where each vertex corresponds to the corners of each patch. In addition, when moving a vertex, I notice that the curvature of the isoparm also reacts differnent then how the curvers of the splines react in Animation Master. For example, when you select a vertex in Animation Master, and you move that one vertex, only that one vertex moves and the curveature of the splines adjusts itself between the distances of the vertices that are adjacent to that one vertex you are moving. However, in Maya, you select vertex and move it a distance, not only that one vertex gets moved, but also the vertices that are adjacent to that one vertex also adjusts itself to keep its correct curve. I am extramly not use to this. In addition, I also tried downloading the cartoon dog tutorial like a couple others here who suggested that this would be a good start. Though I found that the video was a little to advance for me, face paced, and did not explain how they where selecting the vertices. Especially when the person who did this tutorial would place his mouse in one area and then puff, somehow a bunch of vertices get selected. He didn't drag select, he just click on one area and a bunch of the vertices got selected. So my question is, is there a more basic version of tutorials in here that explain in more detail how to control the vertices with NURBS?
