xsimrAttributeData Struct Reference

---

Detailed Description

A structure containing the information for a single attribute.

Each attribute has a name and a type. The tag points to a miUserdata blob that contains a flat array of xsimrPointCloudData::nb_particles attribute values.

Note:

If the xsimrAttributeData::constant flag is miTRUE, then all the attribute entries are the same value and therefore only the first attribute entry is valid to conserve space.

xsimrAttributeType, xsimrPointCloudData, xsimrParticleShape

Since:

7.0

Example:

Example demonstrating how to use the xsimrAttributeData structure

        miScalar getSizeAtIndex( siParticleAttribute *attr, miUint pid, miUint index )
        {
            miUserdata      *data_ptr;
            miScalar        *size_ptr;
            miScalar        result;

            if( index >= attr->count )
                index = attr->count - 1;

            data_ptr = (miUserdata *)mi_db_access( attr->tag );
            size_ptr = (miScalar *)&data_ptr->parameters[ 0 ];
            if( attr->constant )
                result = size_ptr[ 0 ];
            else
                result = size_ptr[ pid * attr->count + index ];

            mi_db_unpin( attr_size->tag );

            return( result );
        }
