Hello, I have an issue with texturing, I am using tri-planar but it's not working for me any suggestion?
a working sample integrated with Luna frank here sample
https://github.com/fido9dido/Dual-Contour
the code for tri-planar in
https://github.com/fido9dido/Dual-Contour/blob/master/TexWaves/Shaders/Default.hlsl
and the Dual Contour is in CreateCubeGrid here
https://github.com/fido9dido/Dual-Contour/blob/master/Common/GeometryGenerator.cpp
This is the result I get from this code, only one of the 3 axes is rendered the rest are stretched as you can see,
I expect the result to be somewhere in between these two images, the image below has terrible colors but the terrain is somewhat wrapped, yet still it's not the best result
The most likely issues is that your normals are a bit off. Can you output those to verify they are correct? A simple NdotL lighting shader (untextured) would do the trick.
Yeah thanks, you are right, I was told it's a normal issue, the way normal was calculated was through an approximation of tangent, I changed that to the cross product of edges, here's how it looks before and after, Now I am looking for a way to calculate the weighted normals per vertex.

What you are doing there looks fine - sum and normalise is the usual method. The cross-products at each edge are already weighted by triangle area if you don't normalise them before summing.
