Hi all!
I have an interesting visual problem I would like to get some feedback on.
First I have a very complicated model loaded and displayed.
Next I shoot the model and show the path of the bullet thought the model.
This is currently implemented with 4 clipping planes giving me a cube along the trajectory of the bullet. I can view the elements internal to my model allowing me the ability to rotate around and inspect which is ultimately the goal.
Now I would like to add multiple shots through the model without the need to re-draw the model every time. Basically a 3d stencil where I could render elements into it, then render my model having it draw the areas that are contained within the volumes I have rendered into the 3d stencil.
I have investigated stencil buffers but this only functions with pixels… No good, I basically would get a series of stripes showing the outside of my model. I have also reviewed geometry shaders which seems an ill fit for this problem.
Any other ideas?
Thanks!
