The Evas_Canvas3D_Mesh structure manages key-frame based mesh animations for geometrical objects like character models, terrain, buildings, and other such visible objects. Each mesh frame can have its own material and geometric data. Blending functions, fog effects, level of detail boundaries, and shadow properties are also supported.

Like other data objects, a mesh definition is located and oriented in the canvas with one or more nodes, with the mesh transformed from its modeling coordinate space to the node's coordinate space. The frame number is also tracked by the node, permitting creation of multiple nodes in the canvas each set to a different animation frame, for example.

Unlike camera and light objects, multiple meshes can be contained in a single node.
