Raydium 3D Game Engine

For working parallax mapping is needed TBN calculation, because TRI file contain only one normal, is created tangent and bibormal for every vertex after loading?

When not, then it's necessery here is good and working method:

Hello,

I really have no idea

What is parallax mapping Tbn

I can have a look at tri file loading it seem that tangent are computed:


normal.c line 74

Is it what you are looking for ?




Xfennec some help

Have a nice day

Ouille

T = Tangent
B = Binormal
N = Normal

normal.c looks good, but then is problem in parabump shader, because heightmap is shaded always from view direction end not from light position.

I'm probably a bit late here, but have a look at chapter 49.1 from the documentation: Raydium computes and provides a tangent attribute to shaders.
