I was wondering if the YOST twist IPAS has the ability to define spline twist amounts for the length of the twist axis. I have written my own simple twist program that just linearly twists objects. But I am working on one that you set the twist amount using splines(like in the lofter) and the axis of twist can be rotated to any angle. If the Yost twist can do this then I don't want to waste my time. I used the FFD IPAS (free-form deformation?) to twist an object. I selected the top layer of verts & rotated them 90 degrees, then the next to top and rotated them 60 degrees etc… I made a couple twists and they are very nice, especially because of the spline functioning of the IPAS. linear twists are no good, spline control is necessary. The picture of the twisted 'M' I have from the YOST IPAS ad looks linear, like the ones I produced with my early program. But the ad said there is some kind of bias control. Any clarity on this subject would help. – – — — —– ——– ————- ——————— ———————————-Will

Our twist.pxp on disk3 only does linear twists. The bias control is for biasing the center of the twist from one end to the other. Your spline twist sounds like a hit. Have you seen the real-time rendering library that we uploaded to the developer section? A spline twister with rt preview would be a blast. – G

I couldn't find the real time rendering library. What is the file name for it? I'll be purchasing an IPAS dev. kit soon and I never thought a PC had the power to do real time. I saw a preview of R4 at a seminar a while ago and was amazed at how fast it rendered the shaded man in the IK module. Thanks for the info.———————————() Will

Hi Will, << I couldn't find the real time rendering library. What is the file name for it? >> The source code was made available by Gary to individuals participating in the Autodesk MultiMedia Developer Program. It is found in the MM DEV Section of the lib.
