Hello,
My name is Rodrigo Hernandez and I am writing some code to add an
Octahedron primitive
(dubbed "octaspehere" following the icosphere convention).
I have already managed to add the code, however I have a couple of
questions before submitting a patch:
1- My changes are on header_info.c and editmesh_add.c, I reckon I also
need to add some code to
python\api2_2x\meshPrimitive.c in order to expose the function to Python
(am I right?), but I also noticed
that the file toolbox.c in the create_mesh_sublevel function has
something that looks vaguely as a primitive menu,
How should I modify it in order to add the new primitive? would just
adding the line for octasphere do?
My code works without any changes to this file, so I am wondering what
exactly does it do.
2 - In order not to reinvent the wheel I just made a search for the
string icosphere and duplicated the code, then
made the appropriate modifications, I noticed the static arrays icoverts
and icofaces.
I noticed that icoverts are normal vectors multiplied by 200, I use the
length 1 normal vectors on my octaverts,
it works fine, but I am wondering if I should be using the times 200
version instead, is this some sort of floating
point safeguard? the octaverts are actually coaxial, so I doubt there
would be any problems,
but I rather use the Blender standard and keep everything consistent...
I might have just answered my own question there.
So, thats it for now.
Thanks.
