## Detailed Description

Encapsulates the data from a GeomVertexData, pre-fetched for one stage of the pipeline.

Does not hold a reference to the GeomVertexData, so make sure it does not go out of scope.

## Member Function Documentation

## ◆ copy_row_from()

void GeomVertexDataPipelineWriter::copy_row_from | ( | int | dest_row,
|  | const GeomVertexDataPipelineReader & | source,
|  | int | source_row
| ) |  |

Copies a single row of the data from the other array into the indicated row of this array.

In this case, the source format must exactly match the destination format.

Don't call this in a downstream thread unless you don't mind it blowing away other changes you might have recently made in an upstream thread.
