1.4 how to display triangle meshes

[mafshar]

Hi!

I am able to load the matrices V and F, but I am a little confused as to how to display them/go about rendering them in the image using the ray-tracing technique.

Thank you in advance!

Hi,

It's actual similar to the sphere case, only difference is that you are dealing with triangles now. Just treat the mesh as many independent triangles and follow through the ray tracing slide.

Best,

I'm wondering which perspective should we use for this question? Perspective or orthogonal?

@majia67 Both are fine, if you are using a general implementation it's just a line of difference. Perspective is better because you don't need to tune to hit the mirror afterward.
