◆ compute_sizes()
|
pure virtual |
To be implemented by a derived class to specify how many attributes, indices and chunks the PainterAttributeDataFiller will fill. All attributes and indices are on a common array. A chunk is a selection of attribute and index data. Each of the outputs is initialized as zero.
- Parameters
-
[out] number_attributes number of total attributes to be set [out] number_indices number of total indices to be set [out] number_attribute_chunks number of attribute chunks to be set [out] number_index_chunks number of index chunks to be set [out] number_z_ranges the number of z-ranges to be set; z-ranges of PainterAttribtueData are accessed by PainterAttributeData::z_ranges() and PainterAttributeData::z_range().
◆ fill_data()
|
pure virtual |
To be implemented by a derived class to fill data.
- Parameters
-
attributes location to which to place attributes indices location to which to place indices attrib_chunks location to which to fill attribute chunks; each element of attrib_chunks must be a sub-array of attributes. Initialized so that each element is an empty array. index_chunks location to which to fill index chunks; each element of attrib_chunks must be a sub-array of indices. Initialized so that each element is an empty array. zranges location to which to fill the z-range values (PainterAttributeData::z_ranges()). index_adjusts location to which to fill the index adjust value (PainterAttributeData::index_adjust_chunks()).
