    NextParticle()

    Advances the pointer to the next particle in the buffer, so that its first vertex can be written
    NextSegment()

    Advances the pointer to the next segment in the buffer, so that its first vertex can be written
    NextVertex()

    Advances the pointer to the next vertex in the buffer, so that it can be written
    SetAttribute(AttributeAccessor, IntPtr)

    Sets the data for the current vertex using the provided AttributeAccessor
    SetAttributePerParticle(AttributeAccessor, IntPtr)

    Sets the same data for the all vertices in the current particle using the provided AttributeAccessor
    SetAttributePerSegment(AttributeAccessor, IntPtr)

    Sets the same data for the all vertices in the current particle using the provided AttributeAccessor
    SetVerticesPerSegment(Int32, Int32, Int32)

    Sets how many vertices are associated with the first, middle and last quad segments of the buffer. In case of billboards 1 segment = 1 quad but other shapes might be laid out differently
    StartOver()

    Moves the index to the beginning of the buffer so that the data can be filled from the first particle again
    TransformAttributePerParticle<T, U>(AttributeAccessor, AttributeAccessor, IAttributeTransformer<T, U>, ref U)
    TransformAttributePerSegment<T, U>(AttributeAccessor, AttributeAccessor, IAttributeTransformer<T, U>, ref U)

    Transforms attribute data using already written data from another attribute
