Examples of com.jme3.scene.Mesh

com.jme3.scene.Node
Mesh is used to store rendering data.
All visible elements in a scene are represented by meshes. Meshes may contain three types of geometric primitives:
- Points - Every vertex represents a single point in space, the size of each point is specified via {@link Mesh#setPointSize(float) }. Points can also be used for {@link RenderState#setPointSprite(boolean) pointsprite} mode.
- Lines - 2 vertices represent a line segment, with the width specified via {@link Mesh#setLineWidth(float) }.
- Triangles - 3 vertices represent a solid triangle primitive.
