LOFTING CURVES IN GRASSHOPPER
LOFTING CURVES IN GRASSHOPPER Learning to use the programs Rhino and Grasshopper in conjunction was the main agenda of this week’s exercise. In doing so we were instructed to create a set of curves, lofting them first through rhino and then through grasshopper. From this the importance of grasshopper was seen.
The curves of the shape were drawn in rhino and then referenced in Grasshopper. By doing so a loft which could be manipulated was constructed. The top image displays the manipulation of the first loft to the last. After each manipulation the result was ‘baked’ from grasshopper into Rhino. The grasshopper base is the red shaded object in the bottom left image. Here we can see the working process of manipulation. The left screen-grab shows the ‘bake’ having just been performed. The red curves can be seen underneath. The shape has been derived from these curves which are red as they are connected to grasshopper.
The bottom right screen-grab shows the initial lofted curve I made through the Rhino ‘loft’ command. Whilst this may be a faster method originally, manipulation is not able to be completed with ease. Instead of the loft moving with the curves as the control points are moves, as it does in Grasshopper, the loft remains stationary, only the curves themselves moving.
At the suggestion of the video, I tried to find an output which I could input by surface into. I tried to create a panelling system with a square, which I made on grasshopper. It became a little too complex and I was unable to make panels on my lofted shape. Within a box I experimented in creating 3D cells. They were then taken out from the box and randomly deleted to play with different forms. This was done with the Voroni3D command which created the cells around a selection of points I created within the box. I proceeded to use a similar concept on a lofted form which I had created. This time using the Octree command, I placed points on my surface and boxes were created on it. This can be seen in the screen grab below.
