◆ defaultname

const char* LayerTypeInfo::defaultname

Referenced by CustomData_external_write().

◆ free

cd_free LayerTypeInfo::free

a function to destruct this layer's data.

Note: implementations should make sure that the data pointer itself is not freed.

◆ initminmax

void(* LayerTypeInfo::initminmax) (void *min, void *max)

Definition at line 186 of file customdata.cc.

Referenced by CustomData_data_initminmax(), and CustomData_layer_has_math().

◆ interp

cd_interp LayerTypeInfo::interp

a function to interpolate between count source elements of this layer's data and store the result in dest if weights == null they should default to 1

weights gives the weight for each element in sources count gives the number of elements in sources

Note: in some cases dest pointer is in sources so all functions have to take this into account and delay applying changes while reading from sources. See #32395.
