Mesh Problem

[yellowspark]

Hello,

I recently started to build my own MeshGenerator based on WoWMapper and BananaMPQ, however I am facing some issues.

1) The rotation seems to be flipped which makes the navigation in Recast hilariously hard. This is how it looks like on startup:

I tried mixing around the cords, however the result just seems to be worse.


2) The poly mesh is completely wrong and I can't generate any path where I should be able to, only on mesh where I shouldn't be able to?

It's important to remember that:

Unlike most coordinate systems Z is used for the height, Y is used for the width and X is used for the depth.
Y is "reversed". The more you go to the right (if north is up), the more it decreases.

I can understand why they use Z as height, but can't - why they reverse east-west (in game roll rotation is counter-clockwise, and Y is inverted)

// wow to recast
inline static void w2r(const float *o, float *r)
{
r[0] = -o[1]; r[1] = o[2]; r[2] = -o[0];
}

// recast to wow
inline static void r2w(const float *o, float *r)
{
r[0] = -o[2]; r[1] = -o[0]; r[2] = o[1];
}

I can understand why they use Z as height, but can't - why they reverse east-west (in game roll rotation is counter-clockwise, and Y is inverted)

It's a right-handed coordinate system. They're by far the most common in pure math and physics, and the default in OpenGL.
