VertexData

class VertexData(val positions: List<Vector3> = emptyList(), val textureCoords: List<Vector2> = emptyList(), val colors: List<ColorRGBa> = emptyList(), val normals: List<Vector3> = emptyList(), val tangents: List<Vector3> = emptyList(), val bitangents: List<Vector3> = emptyList()) : IVertexData(source)

Immutable implementation of vertex data for 3D graphics. This class provides a container for vertex attributes such as positions, texture coordinates, colors, normals, tangents, and bitangents.

It implements the IVertexData interface, allowing easy conversion between immutable and mutable representations of vertex data.

Functions

get

operator fun IVertexData.get(index: Int, textureCoordsIndex: Int = index, colorsIndex: Int = index, normalsIndex: Int = index, tangentsIndex: Int = index, bitangentsIndex: Int = index): Point

Retrieves a Point instance from the vertex data at the specified indices. The indices allow access to positions, texture coordinates, colors, normals, tangents, and bitangents.

toMeshData

fun VertexData.toMeshData(): MeshData

Converts the vertex data into a MeshData representation by constructing the indexed polygons based on the vertex data attributes such as positions, texture coordinates, colors, normals, tangents, and bitangents.

toMutableVertexData

open override fun toMutableVertexData(): MutableVertexData

Converts the vertex data represented by the current instance into a mutable MutableVertexData object. This includes attributes such as positions, texture coordinates, colors, normals, tangents, and bitangents.

toVertexBuffer

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

Converts the vertex data stored in the IVertexData instance to a VertexBuffer. The method iterates through the vertex attributes such as positions, normals, texture coordinates, and colors, and writes them sequentially into the provided or newly created VertexBuffer. Missing attributes are substituted with default values.

toVertexData

open override fun toVertexData(): VertexData

Converts the vertex data represented by the current instance into an immutable VertexData object. This includes attributes such as positions, texture coordinates, colors, normals, tangents, and bitangents.
