Hello, I have a problem when it comes to collision detection and other stuff. The problem is that I don’t know where my vertexes of my objects is…
example:
I place an object with center in origo with vertexes around origo…then I use opengl glRotated and rotates my object…now how do I know the new positions of my vertexes in my object? without shaders?
thx.
Is there anybody who knows this or can it be done?
or do you haveto rotate the vertex yourself to be able to get the new positions of your vetexes after a rotation?
Hi, I think that you can use feedback mode to retrieve the position of vertices after transformation… but it may be easier to do the math for the transformation and store coordinates to perform your collision detection.
