Parameters

Positions

An array containing positions (in the order x, y, z) used to update a subset of positions in the polyline.

Indices

An array of integers containing the indices into positions. A set of x, y, and z elements is considered a single index.

IndicesOrderHint

Member	Value	Description
eStkGraphicsIndicesOrderHintNotSorted	0	The `indices` passed to `SetPartial` are not sorted. Therefore, the primitive may sort them to improve performance of writing its geometry to video memory.
eStkGraphicsIndicesOrderHintSortedAscending	1	The `indices` passed to `SetPartial` are sorted in ascending order. Therefore, the primitive does not need to sort them. It is recommended to only use `SortedAscending` if it is easy and efficient for you to provide the `indices` in ascending order. For example, do not use a standard sorting algorithm to sort your indices so you can use `SortedAscending`. Instead use `NotSorted` and let the primitive decide what is most efficient.

Remarks

Example

Shows the format of the Positions, Colors and Indices parameters when updating a polyline primitive.
