Aspose.3D for Java offers to manage normals and UV on the geometric shapes. A mesh stores the key properties for every vertex, position in space, and its normal, known as a vector perpendicular to the original surface. The normal is major to shading counts and should be a unit vector. Most mesh formats also support some form of UV coordinates which are a separate 2D representation of the mesh "unfolded" to show what portion of a 2-dimensional texture map to apply to different polygons of the mesh....object as narrated here and then point node to the Mesh geometry by...to perform per-pixel normal/color. A per-vertex information like...
