In 3D graphics, vertex attributes define per-vertex data necessary<br>
for rendering, animation, shading, and so on.<br>
These attributes include geometric properties such as<br>
position, normal, tangents, texture mapping information (UV coordinates),<br>
shading data (vertex colors), and<br>
deformation information (skinning weights and blend shapes). <br>
<br>
<br>
In this discussion of vertex attributes, the only one I don't recall<br>
seeing in X3D is tangent? <br>
