Detailed Description

This object provides a high-level interface for quickly reading a sequence of numeric values from a vertex table.

It is particularly optimized for reading a single column of data values for a series of vertices, without changing columns between each number. Although you can also use one GeomVertexReader to read across the columns if it is convenient, by calling set_column() repeatedly at each vertex, it is faster to read down the columns, and to use a different GeomVertexReader for each column.

Note that a GeomVertexReader does not keep a reference count to the actual vertex data buffer (it grabs the current data buffer from the GeomVertexData whenever set_column() is called). This means that it is important not to keep a GeomVertexReader object around over a long period of time in which the data buffer is likely to be deallocated; it is intended for making a quick pass over the data in one session.

It also means that you should create any GeomVertexWriters *before* creating GeomVertexReaders on the same data, since the writer itself might cause the vertex buffer to be deallocated. Better yet, use a GeomVertexRewriter if you are going to create both of them anyway.

Sets up the reader to use the data type with the indicated name.

Sets up the reader to use the indicated column description on the given array.

inline

Sets up the reader to use the nth data type of the GeomVertexFormat, numbering from 0.

◆ set_force()

void GeomVertexReader::set_force ( bool force)
inline

Sets the value of the force flag.

When this is true (the default), vertex data will be paged in from disk if necessary. When this is false, the GeomVertexData will simply return a failure code when attempting to read vertex data that is not resident (but will put it on the queue to become resident later).

Normally, vertex data is always resident, so this will not be an issue. It is only possible for vertex data to be nonresident if you have enabled vertex paging via the GeomVertexArrayData and VertexDataPage interfaces.

Definition at line 205 of file geomVertexReader.I.

◆ set_row()

void GeomVertexReader::set_row ( int row)
inline

Sets the start row to the indicated value.

The reader will begin reading from the indicated row; each subsequent get_data*() call will return the data from the subsequent row. If set_column() is called, the reader will return to this row.

◆ set_row_unsafe()

inline

Sets the start row to the indicated value, without internal checks.

This is the same as set_row(), but it does not check for the possibility that the array has been reallocated internally for some reason; use only when you are confident that the array is unchanged and you really need every bit of available performance.
