public class MeshWriteData
Remarks
You can use this object to fill the values for the vertices and indices only during a callback to the _generateVisualContent delegate. Do not store the passed MeshWriteData outside the scope of _generateVisualContent as Unity could recycle it for other callbacks.
Properties
Property | Description |
|---|---|
| indexCount | The number of indices successfully allocated for VisualElement content drawing. |
| vertexCount | The number of vertices successfully allocated for VisualElement content drawing. |
Methods
Method | Description |
|---|---|
| SetAllIndices | Fills the values of the allocated indices with values copied directly from an array. Each 3 consecutive indices form a single triangle. |
| SetAllVertices | Fills the values of the allocated vertices with values copied directly from an array. When this method is called, it is not possible to use MeshWriteData.SetNextVertex to fill the allocated vertices array. |
| SetNextIndex | Assigns the value of the next index of the allocated indices list. |
| SetNextVertex | Assigns the value of the next vertex of the allocated vertices list. |
