There appears to be an easily fixable error in the Math > Operators > Power component. If you give it an A value of 10 and a B value of 2 you would expect the R output to be 100. Instead it returns 10,000. That is 10 cubed.

As it stands Pow returns A to the power of B+1 for any B value 0 and greater. For B values of -1 or less it gives A to the power of 1.

Thanks,
Steven

1) 10 cubed of course is not 10,000 but 1,000

2) I did some more research and have found some interesting results.

In my original test of Pow I used Panels (to input a constant value) for both the A and B inputs. This gives the odd results. I replaced the B Panel with an integer slider and the Pow component works properly.

When I use a Panel for B I get the following results (A panel is 10):

B=0 R=10
B=1 R=100
B=2 R=10,000
B=3 R=100,000,000

Ouch.... that's embarrasing. I fixed the problem. It only occurs with integers btw. so if you feed the component floating point numbers (10.0 instead of 10) it should work as expected.

Once again,
Thank you David! I just downloaded this version after a Grasshopper hiatus and I am really happy with the changes you've made.

I'm hopefully curious - is there something symmetrical to the weave component yet, like an index-based dispatch component?

I wrote a simple VB component to do this... I've been asking to have it integrated into GH, but no luck so far. Luckily now we have User Components so it's no big deal. I have them at home -- I'll upload them later...

Mesh Shadow seems to be broken:

sorry img is so big...

also meshsplitplane has an issue as well... can anyone replicate this on either component?

It's Rhino5. These are new methods in the RhinoCommon SDK and they won't work in Rhino5 until the next beta goes out.
