Constructor with position, direction and uvw data.

参数

[in]	pos	The position array to sample.
[in]	dir	The direction array to sample.
[in]	uvw	The uvw array to sample.
[in]	allocatedCount	The allocated length of the pos and dir arrays.
[in]	transform	The transform matrix required to convert the position and direction inputs to global space.

◆  FieldInput() [8/11]

Constructor with position, direction and uvw data.

参数

[in]	pos	The position array to sample.
[in]	dir	The direction array to sample.
[in]	uvw	The uvw array to sample.
[in]	allocatedCount	The allocated length of the pos and dir arrays.

◆  FieldInput() [9/11]

Constructor with position, direction and uvw data.

参数

[in]	pos	The position array to sample.
[in]	dir	The direction array to sample.
[in]	uvw	The uvw array to sample.
[in]	allocatedCount	The allocated length of the pos and dir arrays.
[in]	transform	The transform matrix required to convert the position and direction inputs to global space.
[in]	fullCount	(optional) The full position count if count was to big to allocate in pos. Will be allocatedCount unless specified otherwise.

◆  ~FieldInput()

Destructor. FieldInput owns no memory.

◆  FieldInput() [10/11]

Copy constructor NOTE: This performs a dumb raw copy of the FieldInput instance. I.e. internal pointers will be copied and point to the content of the original owner. Field point never owns the data, this is why a standard CopyFrom is not part of this class.

参数

[in]

src

Copy source.

◆  FieldInput() [11/11]

Move constructor

参数

[in]

src

Move source.

成员函数文档编制

◆  MAXON_OPERATOR_MOVE_ASSIGNMENT()

◆  MAXON_OPERATOR_COPY_ASSIGNMENT()

◆  CopyFromRaw()

Performs a raw copy of the the FieldInput described by src. Equivalent to copy construction. NOTE: this is not a CopyFrom, see copy constructor note above.

参数

[in]

src

Source for the duplication.

◆  GetSubBlock()

Return a FieldInput struct for a subset of the original array. This can be used to pass smaller blocks to the field processing threads.

参数

[in]	offset	The subblock start offset in the full array (0 based).
[in]	blockSize	The size of the desired subblock.

返回

The sub FieldInput structure. Will be empty if request is out of bounds.

◆  GetCount()

Gets the number of elements in the FieldInput

返回

The count.

◆  GetOffset()

Gets the offset of the first element in the full arrays.

返回

The offset.

◆  IsValid()

Checks if the FieldInput allocations and sizes are valid. Empty FieldInput is considered valid.

◆  IsPopulated()

Checks if the FieldInput is valid and non-empty.

Member Data Documentation

◆  _position

The position values for the array of points, if this is a sub-block then element 0 is at _blockOffset within the larger array, caller owns this array, size must match or be greater than count value @required.

◆  _direction

The (optional) direction values for the array of points, if this is a sub-block then element 0 is at _blockOffset within the larger array, caller owns this array, size must match or be greater than count value.

◆  _uvw

The (optional) uvw values for the array of points, if this is a sub-block then element 0 is at _blockOffset within the larger array, caller owns this array, size must match or be greater than count value.

◆  _blockCount

The number of elements in the array to be processed (for this processing block, this should be treated as the count to use when iterating over elements in FieldObject and FieldLayer .

◆  _blockOffset

The offset (starting point) of the elements if a portion of a larger array, used e.g. to get the actual index in the array actualIndex = index - points._blockOffset;.

◆  _fullArraySize

The full size of the source data, this may be larger than blockCount, also might be larger then the size of the allocated pointers within the FieldInput class. Do no use this size to browse the arrays!

◆  _transform

The transform matrix for the points in the input block, use this to bring the _position and _direction arrays into world space or the local space of your FieldObject .

◆  _allocatedArraySize

The allocated size of the vector arrays. Use this with _blockOffset to browse all the input vectors safely. Might be larger than blockCount.
