SceneMesh provides functionality for creating, manipulating, and rendering 3D geometry with materials. It supports various primitive shapes (box, sphere, quad, etc.) as well as loading 3D models from files.

Functions

Name	Summary
calculateNodeGlobalMatrix	fun calculateNodeGlobalMatrix(index: Int): Matrix44 Calculates the global transformation matrix of a node.
computeCombinedBounds	fun computeCombinedBounds(): Bound3D Computes the combined bounding box of all geometry in this mesh.
destroy	fun destroy()
getAnimationTracks	fun getAnimationTracks(): Array<AnimationTrack> Gets all animation tracks defined in this mesh.
getMaterial	fun getMaterial(index: Int): SceneMaterial? Gets a material from this mesh by index. This material is the "parent" of any SceneObjects instanced from this mesh. Any changes to attributes will apply to the non-overridden properties of the child materials. fun getMaterial(material: String): SceneMaterial? Gets a material by name. This material is the "parent" of any SceneObjects instanced from this mesh. Any changes to attributes will apply to the non-overridden properties of the child materials.
getMaterialIndex	fun getMaterialIndex(material: String): Int Gets the index of a material by name.
getMaterialIndexForNodeMeshElement	fun getMaterialIndexForNodeMeshElement(nodeId: Int, meshElementId: Int): Int Gets the material index for a specific node and mesh element.
getMaterialName	fun getMaterialName(materialIndex: Int): String Gets the name of a material by index.
getNodeCount	fun getNodeCount(): Int Gets the number of nodes in this mesh.
getNodeLocalMatrix	fun getNodeLocalMatrix(index: Int): Matrix44 Gets the local transformation matrix of a node.
getNodeName	fun getNodeName(index: Int): String Gets the name of a node by index.
updateCylinderSurface	fun updateCylinderSurface(radius: Float, height: Float, fractionOfCircle: Float) Updates the geometry of a cylinder surface mesh.
updateWithTriangleMesh	fun updateWithTriangleMesh(triMesh: TriangleMesh, updateBVH: Boolean = false) Updates this mesh with geometry from a triangle mesh.
