Re: [Algorithms] Triangle strips still useful?

[Tomas A. @ Z. <ta...@ze...>]

Another way to think about the triangle strips lists, etc. It is just a way
to represent a patch object. Where the patch is already been texelated for
you. Then it will be worth adding a CULL cone-sphere. Cone-sphere I define
it as a sphere that can become a cone such you will have a normal and a
parametric value that will go from [1,-1] along the normal which will
describe the uni-sphere extent. Such if you do the dot product between the
camera and the normal you can reject base on the parametric value. The
hardware could use this cone-sphere to skip a hold batch of triangles. 

 

But there is a good chance that triangles are going to just become a
specialize primitive as pixel shader becomes better at giving good parallax
and the geometry shader may be able to improve the silhouette. The hardware
guys just need to add a new texture format that will allow for real time
raytracing of it. Similar to the

ping.pdf. It will be a good first step towards a more robust raytracer. 

 

But I guess I am changing the subject here.
