Properties

coordsPerVertex

Returns the number of position coordinates per vertex. This will be 2 or 3.

abstract val coordsPerVertex: Int

modelMatrix

The model matrix for this object. Defaults to the identity matrix, but can be accessed and modified.

val modelMatrix: FloatArray

vertexArray

Returns the array of vertices. To avoid allocations, this returns internal state. The caller must not modify it.

abstract var vertexArray: FloatBuffer

vertexArrayVersion

var vertexArrayVersion: Int

vertexCount

Returns the number of vertices stored in the vertex array.

open val vertexCount: Int

vertexStride

Returns the width, in bytes, of the data for each vertex.

open val vertexStride: Int
