**set_indices**(Indices indices, int n_indices)

Cogl.Primitive.set_indices – doc Reference Manual

Associates a sequence of Indices with the given this.

Indices provide a way to virtualize your real vertex data by providing a sequence of indices that index into your real vertex data. The GPU will walk though the index values to indirectly lookup the data for each vertex instead of sequentially walking through the data directly. This lets you save memory by indexing shared data multiple times instead of duplicating the data.

The value passed as `n_indices`

will simply update the Primitive <
structfield>n_vertices</structfield> property as if set_n_vertices
were called. This property defines the number of vertices to draw or, put another way, how many indices should be read from ```
indices
```

when drawing.

<note>The Primitive <structfield>first_vertex</structfield> property also affects drawing with indices by defining the first entry of the indices to start drawing from.</note>
