Check if camera sees quad

[schlonzo]

hi all,

I want to check if my camera sees certain 2d quads. I get the “look direction” vector from the view matrix. But how to I check which of the vectors deviate too much from the view direction?

I have no idea if there is something ready made to use in vvvv, but generally you’d want to look at “view frustum culling”

when you type “frustrum” in the nodebrowser you’ll see

• FrustrumTest (DX11.Validator)
• ViewFrustrumCulling (EX9.Geometry Mesh)
  that both come with helppatches.
