Following the video tutorial closely I was able to understand how to find the average of points on a singular surface and then see how this became an issue when trying to find the average of points divided across numerous surfaces. We then looked at giving each of the points a coordinance that would enable us to manipulate the path in which each of these coordinates were connected. The reason for doing this was to allow us to create a pattern on a surface reflected within the varying connection of points. By dividing the coordinates into rows and columns we could then determine how the connections were made between each, whether to offset the rows, columns or both by varying degree to then see what aesthetic output was created. The output was given in the form of a polyline
which was then generated into a planar surface. Initially I struggled with this as the command was asking for a planarsrf node and I did not have that with my updated version of Grasshopper so I did some quick research and found out that the command had been replaced by a node called a ‘boundary surface’. This enabled me to achieve the desired outcome of the tutorial. Below are the two different patterns generated by manipulated the amount of offset given to the rows and columns of each coordinate.
By creating all that was asked for in the tutorial I then looked to creating my own patterns. I attempted numerous different inputs for both the rows and columns. My outcomes are displayed in the three images above. As you can see the outcomes were not completely successfull. It appeared to me that the offset I was generating was confining the pattern between the first and second column and row. I need to look further in to how to ensure the pattern will cover the surface entirely.
After my attempts did not generate the most desired outcomes I became curious as to whether this technique would work on different surfaces. I quickly generated a surface from a few curves and applied the same constraints to the coordinates as given in the tutorials outcomes. I quickly found out that the same connections between coordinates do not work when you change the surface. Below is the surface that I generated and a basic offset of coordinates that worked.
