Get Vertex Index

[macklebee]

How can you determine what vertex index you are grabbing from a particular triangle or surface?

[macklebee]

For example: you have a 5mx5m mesh plane that has a 5x5 division resulting in 50 triangles that are all using the exact same material (which then would be considered one surface). Now using a pick based on mouse position on the mesh, how would you determine what vertex your mouse was over? I do not see a GetVertex() or GetTriangle() that could allow you determine which vertex index you are near... and you need this vertex index to be able to get/set the vertex position, color, etc..

 

Unless I am missing something obvious, it appears theres a command missing in the wiki?

TPick::triangle

[macklebee]

thanks masterxilo... i just tried it in lua and it always returns a zero. I haven't tried it yet in bmax but will do so tomorrow after a good night's rest.

[macklebee]

hmmm. it returns 0 in a bmax program as well... does this work anymore? I am using 2.32... perhaps I should try earlier versions...

[macklebee]

does pick.triangle only work for C? can anyone thats using C or C++ check to see if it returns anything besides zero? In lua and bmax that's all it ever returns...
