All visible game elements in a scene, whether it is a Model or a Shape, are made up of polygon meshes. JME3 has a com.jme3.scene.Mesh class that represents all meshes.

.You can use default Shapes as meshes; load 3D models (i.e. meshes created in external applications); or create free-form custom meshes programmatically.
The VertexBuffer contains a particular type of geometry data used by Meshes. Every VertexBuffer set on a Mesh is sent as an attribute to the vertex shader to be processed.
Vertex Buffer Type | Description |
---|---|
Type.Position | Position of the vertex (3 floats) |
Type.Index | Specifies the index buffer, must contain integer data. |
Type.TexCoord | Texture coordinate |
Type.TexCoord2 | Texture coordinate #2 |
Type.Normal | Normal vector, normalized. |
Type.Tangent | Tangent vector, normalized. |
Type.Binormal | Binormal vector, normalized. |
Type.Color | Color and Alpha (4 floats) |
Type.Size | The size of the point when using point buffers. |
Type.InterleavedData | Specifies the source data for various vertex buffers when interleaving is used. |
Type.BindPosePosition | Inital vertex position, used with animation. |
Type.BindPoseNormal | Inital vertex normals, used with animation |
Type.BoneWeight | Bone weights, used with animation |
Type.BoneIndex | Bone indices, used with animation |
Mesh method | Description |
---|---|
setLineWidth(1) | |
setPointSize(4.0f) | |
setBound(boundingVolume) | |
setStatic() | Locks the mesh so you cannot modify it anymore, thus optimizing its data (faster). |
setDynamic() | Unlocks the mesh so you can modified it, but this will un-optimize the data (slower). |
setMode(Mesh.Mode.Points) | Used to set mesh modes, see below |
getId() | |
getTriangle(int,tri) | |
scaleTextureCoordinates(Vector2f) |
Mesh Mode | Description |
---|---|
Mesh.Mode.Points | Show only corner points |
Mesh.Mode.Lines | Show lines |
Mesh.Mode.LineLoop | ? |
Mesh.Mode.LineStrip | ? |
Mesh.Mode.Triangles | ? |
Mesh.Mode.TriangleStrip | ? |
Mesh.Mode.TriangleFan | ? |
Mesh.Mode.Hybrid | ? |
