Functions

add

fun add(newVertices: FloatArray, srcOffset: Int = 0, dstOffset: Int = 0, count: Int = newVertices.size)

Add a list of existing vertices to the geometry.

addIndex

fun addIndex(idx: Int)

Add an index.

addIndices

fun addIndices(vararg indices: Int)

fun addIndices(indices: List<Int>)

Adds a list of indices.

addTriIndices

fun addTriIndices(i0: Int, i1: Int, i2: Int)

Adds three indices as a "tri".

addVertex

inline fun addVertex(action: VertexView.() -> Unit): Int

Add a single vertex to the geometry using a VertexView.

batchUpdate

inline fun batchUpdate(rebuildBounds: Boolean = false, block: MeshGeometry.() -> Unit)

Mark this geometry as a batch update. This does nothing on its own. Use isBatchUpdate to handle.

clear

fun clear()

Clears the vertices.

clearIndices

fun clearIndices()

Clears the indices.

forEach

inline fun forEach(block: (VertexView) -> Unit)

get

operator fun get(i: Int): VertexView

indicesAsQuad

fun indicesAsQuad()

Converts the array of indices based on a quad.

indicesAsTri

fun indicesAsTri()

Converts the array of indices based on a triangle.

rebuildBounds

fun rebuildBounds()

skip

fun skip(totalVertices: Int)

This moves the current an X amount of vertices from the current vertex index. This takes into account the vertexSize.
