IVertexData

Interface representing vertex data for 3D graphics. This includes attributes such as positions, texture coordinates, colors, normals, tangents, and bitangents. It provides methods to convert the data to either immutable or mutable vertex data representations.

Inheritors

VertexData

MutableVertexData

Properties

bitangents

abstract val bitangents: List<Vector3>

Vertex bitangents

colors

abstract val colors: List<ColorRGBa>

Vertex colors

normals

abstract val normals: List<Vector3>

Vertex normals

positions

abstract val positions: List<Vector3>

Vertex positions

tangents

abstract val tangents: List<Vector3>

Vertex tangents

textureCoords

abstract val textureCoords: List<Vector2>

Vertex texture coordinates

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.

toMutableVertexData

abstract 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

abstract 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.
