Methods

createInstancedMesh

createInstancedMesh(geometry: BufferGeometry, g3d: G3d, instances: number[], useAlpha: boolean): Mesh
Creates a InstancedMesh from g3d data and given instance indices

Returns
a THREE.InstancedMesh
Parameters
- geometry: BufferGeometry
  
  Geometry to use in the mesh
- g3d: G3d
- instances: number[]
  
  Instance indices for which matrices will be applied to the mesh
- useAlpha: boolean
  
  Specify whether to use RGB or RGBA
Returns Mesh
- Defined in src/vim-loader/legacy/meshBuilder.ts:103

createInstancedMeshes

createInstancedMeshes(g3d: G3d, args: InstancingArgs): Mesh[]
Creates Instanced Meshes from the g3d data

Returns
an array of THREE.InstancedMesh
Parameters
- g3d: G3d
- args: InstancingArgs
Returns Mesh[]
- Defined in src/vim-loader/legacy/meshBuilder.ts:36

createMergedMesh

createMergedMesh(g3d: G3d, args: MergeArgs): Mesh
Create a merged mesh from g3d instance indices

Returns
a VIM.Mesh or undefined if the mesh would be empty
Parameters
- g3d: G3d
- args: MergeArgs
Returns Mesh
- Defined in src/vim-loader/legacy/meshBuilder.ts:137

createWireframe

createWireframe(g3d: G3d, instances: number[]): LineSegments<WireframeGeometry<BufferGeometry>, LineBasicMaterial>
Create a wireframe mesh from g3d instance indices

Returns
a THREE.Mesh
Parameters
- g3d: G3d
- instances: number[]
  
  g3d instance indices to be included in the merged mesh. All mergeable meshes if undefined.
Returns LineSegments<WireframeGeometry<BufferGeometry>, LineBasicMaterial>
