Howto create a custom mesh with a vertexbuffer

vvvv beta general

Hello world.

I’m pretty new to vvvv. Willing to understand but still struggling…

At this moment I’m trying to understand how the mesh function in combination with a vertex buffer works.

The help file of the mesh function describes a method to create a square into a mesh with the help of a vertex buffer.

But is it possible to create different geometrical figures with the help of a vertexbuffer for example a seastar. which means 10 adjustable points in the mesh.

I have tried to add extra vertex positions and texture coordinates, to no avail.

can someone give me some hint and tips to create a custom mesh?

i think you will have to create more complexs meshs in a 3d software and import to 4v … or work with the vvvvs ex9.geometry (grid, teapot , box , etc)

Thanks, for the reply plic.I was thinking the same. But is it possible to adjust imported x files in vvvv?

here is my basic vertex buffer patch, might give you some more understanding to that i think it’s possible with advanced vertex buffer and shader wrote to it. see if someone know how to deal with it proper ;)
