I can't find anyway to scale a vector or vertex position in Irrlicht....

 

irr::core::matrix4 scale, translation;
        scale.setScale(.005f);
        for(int x = 0; x < vertex.size(); ++x)
        {
            translation.makeIdentity();
            translation.setTranslation(vertex[x].Pos);
            translation *=scale;
            vertex[x].Pos = translation.getTranslation();
        }

 

I need to shrink my image and not seeing anyway to do this.

 

drawIndexedTriangleFan()

 

I am calling that vs. using nodes....

 

Thanks!

You don't need a matrix to scale or translate a vector. You just need to multiply by another vector, or add another vector.
