Hi, As seems to be the case with a few people, I'm quite new to Grasshopper, and loving what I get out of it so far - thanks David. However, I'm still on a ridiculously elementary level both when it comes to GH and maths, so here we have several stupid questions baked into one:
I'm trying to create a model that begins with a three-dimensional 'bounding box' object. This would hopefully become asymmetrical later on, but let's say for the sake of simplicity that it's a 5 x 5 x 5 unit box. Let's think of this as if we were viewing it in front elevation. On the left hand side, we have two corners, one top, one bottom. I'd like to create a curve that stretches, say, one unit from the bottom corner upwards (from 0 to 1), and I want to be able to edit this curve in different ways: turn it into a sine curve, a bezier curve, a power curve, and so on, and tweak it into different positions and curvatures. I then want to do the same with the corner on the top left hand side, and then blend the curves together. I then want to do this for each corner of the bounding box, and loft between them, creating a new, deformed object. In other words, I'm trying to create a set of three-dimensional corners that can be updated and that control the surfaces in between them. And I want to do lots of iterations - hence Grasshopper. 1) How do I create the corner curves? Can I do this with the Graph Editor? I understand how to make a curve using a range (with sliders) and an expression, but this doesn't give me as much intuitive control as I would like. The Graph Editor seems to be able to do what I want, but I have no idea how to use it and can't find any info. 2) How do I map these corners onto my bounding box? 3) How do I blend between the end points of my corner curves? Can this be done in Grasshopper, or can I link it to the Rhino BlendCrv command somehow? Many thanks in advance, and once again sorry for bringing up questions the answers to which are probably really obvious. /Mags
