Transparency Question
Apr 26 2013 | 1:44 pm
Hello,
I am trying to make the mesh object transparent in the positions where the values going in to the mesh are equal to 0. However I want to keep the gradual transparency I have at the moment. In other words, I don't want to see the black plane where there are no deformations but keep the fade out effect I have. It feels like this suppose to be an easy thing to do but couldn't seem to work it out.
Thank you.

- Apr 27 2013 | 9:56 amExcuse my ignorance but what is "vertex displacement matrix"?
- Apr 27 2013 | 10:25 amyour vertices are the ones in jit.gl.mesh. The matrix that displaces them is the output of jit.catch~ - but I think it's the output of the "flow" matrix you're supposed to use for this, too.Multiply that matrix with your alpha channel inside the colorselect patcher, and you should be close.
- Apr 27 2013 | 11:38 amI tried what you told me. I am closer to what I want but not quite there yet. I think I need to get the positions where displacement is zero then multiply it with my alpha channel but I don't know how to do that.
- Apr 28 2013 | 9:25 amOk, I managed to get all the 0 values from a matrix but that didn't work as I hoped. Any other ideas?

- Apr 29 2013 | 10:21 pmno need to bump a thread after one day, on a weekend.the patch you posted looks to me like exactly what you're asking for. what's not working for you?
- Apr 30 2013 | 9:38 amI am sorry for the bump. I have a deadline to meet for my university class, I guess I just panicked a little bit.I am trying to get rid of the black plane while keeping other parts unchanged. I know the the black plane is disappeared right now but some parts of the displaced mesh is also transparent.
