Technique Documentation: Continuous changing through Grasshopper

This assignment aims to generate continuous changing by Grasshopper. The prototype of the calculator is assembled in the model “combine_mesh-Manipulating Terrain (multiple images).gh”, I put several adjustment to make it work for my assignment 4.0.a1

The original calculator shows how a model  gradually changes to another, and cast onto a terrain. Thus, the key adjustments appear to be:

1. Change the two grayscale DEM images with two proper ones.

2. Control changing pace, make it homogenous.

3. Change the terrain with the one “heightfield”(conmand in rhino) by the starting DEM image.

4.Show the contours.

Press Start to continue

Double click the upper picture. In the Image Sampler Settings window, click “…” to change the file path to the target image, click OK. This image will be the starting one.

Change the lower picture to the target ending one, same operation.

Double click the slider, make 0 decimal place, set the min value as 0 and max value as 11. Put a divide calculator, connect the slider to A, set the value of B as 14. And then connect the outcome to the calculators as the original slider. the  This fragment will break the change homogeneously into 15 moments.

a3

Next step is replace the samples grasshopper picked from rhino. Put “Pictureframe” in rhino, select the starting image, and then right click “PictureFrame surface 1”, click “Set one surface”.

 

a5

Then put “heightfield” in rhino, select the starting image and set it as big as the pictureframe, set the Height as 10 meters and number of sample points as 100 x 100. A surface is generated, select it and click mesh from surfacea6, OK to continue.  Right click “starting mesh” in grasshopper, click set one mesh, and select the one in rhino.

a7

At the final step, we need to add contour to the model. Double click blank space in grasshopper, put “contour”, select the “brep or mesh contours”.

a8

Connect the “M” of the final Del calculator to the “S” on contour calculator; Pick one of the “Box Corners” and connect it to “P” on contour calculator; Put a number slider from 0 to 10 and connect it to “D” on the calculator.

a9

So the calculator is done, all I need to wrap up is just slide and bake.
