"3D scene - Create mesh.vi - opacity?"

[atrende]

Hi,

I'm creating 3D objects, which I display in the 3D scene (LV 8.2). Generally it works great, but I have two questions:

1. I don't understand the create mesh.vi. What should it be used for, and how? Is there a way to connect a set of coordinates that describes the mesh?

2. I would like to have some of the objects more or less transparent, so that you can see objects placed behind these objects. I thought the alpha value of the RGBA colour code was the parameter to play with, but alpha = 0 makes the object invisible and all other values of alpha makes it completely opaque. Is there anything else I have to do to make it work?

I found the solution to my first question by looking at the code behind the "Load ASE Geometry.vi". There is an Invoke node meathod called "Set Mesh Parameters", which does the job.

The opacity problem is still unsolved.

Just wondering if the opacity problem has been solved ??

I never solved the opacity problem at that time, but later I assumed that it was the graphics board of my computer that couldn't handle opacity.

I have not yet tried my code on another computer.

Maybe this solves your problem as well
