    • addFace

    • addMesh

      Mesh3D addMesh(Mesh3D mesh)

    • center

      AABB center(ReadonlyVec3D origin)
      Centers the mesh around the given pivot point (the centroid of its AABB). Method also updates & returns the new bounding box.
      Parameters:
      origin - new centroid or null (defaults to {0,0,0})

    • clear

      Mesh3D clear()
      Clears all counters, and vertex & face buffers.

    • computeCentroid

      Vec3D computeCentroid()
      Computes the mesh centroid, the average position of all vertices.
      Returns:
      centre point

    • computeFaceNormals

      Mesh3D computeFaceNormals()
      Re-calculates all face normals.

    • computeVertexNormals

      Mesh3D computeVertexNormals()
      Computes the smooth vertex normals for the entire mesh.
      Returns:
      itself

    • faceOutwards

      Mesh3D faceOutwards()
      Changes the vertex order of faces such that their normal is facing away from the mesh centroid.
      Returns:
      itself

    • flipVertexOrder

      Mesh3D flipVertexOrder()
      Flips the vertex ordering between clockwise and anti-clockwise. Face normals are updated automatically too.
      Returns:
      itself

    • flipYAxis

      Mesh3D flipYAxis()
      Flips all vertices along the Y axis and reverses the vertex ordering of all faces to compensate and keep the direction of normals intact.
      Returns:
      itself

    • getBoundingBox

      AABB getBoundingBox()
      Computes & returns the axis-aligned bounding box of the mesh.
      Returns:
      bounding box

    • getBoundingSphere

      Sphere getBoundingSphere()
      Computes & returns the bounding sphere of the mesh. The origin of the sphere is the mesh's centroid.
      Returns:
      bounding sphere

    • getClosestVertexToPoint

      Vertex getClosestVertexToPoint(ReadonlyVec3D p)

    • getFaces

      Collection<Face> getFaces()

    • getNumFaces

      int getNumFaces()
      Returns the number of triangles used.
      Returns:
      face count

    • getNumVertices

      int getNumVertices()
      Returns the number of actual vertices used (unique vertices).
      Returns:
      vertex count

    • getVertices

      Collection<Vertex> getVertices()

    • init

      Mesh3D init(String name, int numV, int numF)

    • setName

      Mesh3D setName(String name)
