MutableMeshData

data class MutableMeshData(val vertexData: MutableVertexData, val polygons: MutableList<IndexedPolygon>) : IMeshData(source)

Represents mutable mesh data with modifiable vertex data and polygonal structure.

Constructors

MutableMeshData

constructor(vertexData: MutableVertexData, polygons: MutableList<IndexedPolygon>)

Properties

bounds

val IMeshData.bounds: Box

Provides the bounding box of the mesh based on its polygons and associated vertex data.

polygons

open override val polygons: MutableList<IndexedPolygon>

Mutable list of indexed polygons defining the geometric structure of the mesh.

vertexData

open override val vertexData: MutableVertexData

Mutable vertex data instance containing positions, texture coordinates, colors, normals, tangents, and bitangents of vertices.

Functions

isTriangular

fun IMeshData.isTriangular(): Boolean

Checks if all polygons in the mesh are triangular.

join

open override fun join(other: IMeshData): IMeshData

Combines the current mesh data with another mesh data instance.

toMeshData

open override fun toMeshData(): MeshData

Converts the current mesh data into an immutable MeshData instance.

toMutableMeshData

open override fun toMutableMeshData(): MutableMeshData

Converts the current mesh data into a mutable representation.

toPolygons

open override fun toPolygons(): List<Polygon>

Converts the current mesh data into a list of polygons.

toVertexBuffer

fun IMeshData.toVertexBuffer(elementOffset: Int = 0, vertexBuffer: VertexBuffer? = null): VertexBuffer

Converts the current mesh data into a VertexBuffer representation, preparing geometry for rendering.

triangulate

open override fun triangulate(): MutableMeshData

Converts the current mesh data into a fully triangulated form.

weld

fun IMeshData.weld(positionFractBits: Int, textureCoordFractBits: Int = -1, colorFractBits: Int = -1, normalFractBits: Int = -1, tangentFractBits: Int = -1, bitangentFractBits: Int = -1): MeshData

Welds the mesh data by consolidating vertices based on specified fractional bit precision for attributes such as positions, texture coordinates, colors, normals, tangents, and bitangents. This reduces redundant vertices and optimizes the mesh structure.

wireframe

fun IMeshData.wireframe(): List<List<Vector3>>

Generates a wireframe representation of the mesh.
