Parameters

positions

Type: System.Collections.GenericIEnumerableCartesian
A collection of new positions used to update a subset of positions in the polyline.

colors

Type: System.Collections.GenericIEnumerableColor
A collection of new colors used to update a subset of colors in the polyline. There must be one color for each position in positions.

indices

Type: System.Collections.GenericIEnumerableInt32
A collection of zero-based indices that map a corresponding position in positions to a position already in the primitive. For example, if a primitive is first given 5 positions with a call to Set, positions 1 and 3 can be modified with SetPartial by passing in positions containing two new positions and an indices collection with two elements, e.g. [1, 3]. The first position in positions will modify the position at index 1 in the primitive and the second will modify the position at index 3.

indicesOrderHint

Type: AGI.Foundation.Graphics.AdvancedIndicesOrderHint
An optimization hint indicating how indices are sorted.

renderPassHint

Type: AGI.Foundation.Graphics.AdvancedRenderPassHint
An optimization hint indicating the RenderPass implied by colors.

To call SetPartial, the primitive must be constructed with Partial so the primitive builds the data structures necessary for partial updates. See the Set Hint topic for more information on selecting an appropriate value.

If the primitive's AutomaticallyComputeBoundingSphere property is , the primitive's BoundingSphere is computed based the primitive's unmodified positions and the updated positions from the positions collection. Otherwise, it is the caller's responsibility to update the primitive's BoundingSphere to a sphere that encompasses all the positions in the primitive.
