Morphing and instansing

[VeTaL]

Okay, i know that the best way of doing this is shader, but....

 

I have model of fat and thin face... now i want to get a new model: i get every vertex of first model, then from second model, got an equation of "division of the segment in a given ratio" and a coefficient (A).

 

if A = 0 then each vertex of new face is on the place of vertex from first face (they are similar)

if A = 0,5 then i have my own face - between first and second

if A = 1 then my face is similar to second face

 

The question is: do anybody work on this before using Leadwerks? Is this idea effective?

And what about instancing: if i would move one vertex of instanced model, wouldnt all other models change?

I can't see any reason why this wouldn't work although as you say probably more efficiently executed by a shader on the GPU, however as you point out you wouldn't be able to indiviually alter instanced models.

I decied to use not "division of the segment in a given ratio", but equotion

X = (1-A) * X1 + A * X2, where A comes from 0 to 1

 

 

This works, but no instancing: looking like i really need to find someone, who knows shaders well
