data display

[farshizzo]

Hi,

I've created an addon module to make it easy to create height fields. The attached zip file contains the modules (kgarr.py, HeightField.dlc) and a test script (testHeightField.py). I've commented the test script to explain what each command does. Let me know if this isn't what you wanted.

I didn't implement the cylinder because I'm still not clear what it is supposed to look like. Do you have an image or a sample file?

Thanks, as soon as I get a sample of the cylinder, I will send it over.

One other question. Is it possible to apply a color map to the height values? something like this.



It does not have to be exactly like that, but something simular.

Hi,

I've attached a modified version of the addon module that allows setting a color map. The sample script shows how to use this, it also displays a wireframe version of the heightfield over the colored version.

is it easy to get the data from a outside source, like the 50x50 CSV file attached.

If this isn't easy, then I don't know what is

import csv
height = [ [float(val) for val in row] for row in csv.reader(file('data.txt','rUb')) ]

Thanks Again!

Is it easy to map the color to the height of the surface, like in the picture above.

For example, the highest points have an RGB value of 1 0 0 and the lowest points have a value of 0 0 0, any height between has a value between those.

here are some examples of the cylinder







the radius comes from a 2D matrix, one dimension being the points around the cylinder, the other being the points along the cylinder.

Hi,

I've attached a new version of the test script that generates colors based on the height.
