adding points into group


Recommended Posts

Hello everyone,

I have a few questions on how to do certain operations with hdk. I looked through the docs and through example files as much as my brain has permitted me.

1. using GU_PointGroup->add(pt); only keeps one pt in the group on every recook. Is there a version of add that accepts more than one point. Or does an array or something have to be saved to keep track.

2. what functions would i use to read in a bgeo file and manipulate the geo. would it bring in something similar to gdp

3. is there a way to delete a range of points without having to use GA_Range (and if that is the case, then how would one use GA_range

thanks in advance. I'm sorry if these questions sound so basic. Reading through the documentation feels like chasing a rabbit down a rabbit hole.
