MeshAttributeClassInterface Class Reference

#include <mesh_attribute_base.h>

Inheritance diagram for MeshAttributeClassInterface:

详细描述

By implementing this interface, it is possible to define a new mesh attribute type so that a data type can be attached to mesh vertices or to mesh polyvertices. The interface needs to be implemented with the data type description, which has to be registered using MAXON_MESHATTRIBUTE and MAXON_DATATYPE, and all arithmetic and comparison functions.

成员函数文档编制

◆  MAXON_INTERFACE()

MAXON_INTERFACE ( MeshAttributeClassInterface   , MAXON_REFERENCE_CONST   , "net.maxon.mesh_misc.interface.meshattributeclass"    )

private

◆  GetDataType()

Returns the DataType this class manages, e.g. Vector2d32 for UV maps.

返回

The DataType .

◆  InterpolateLinear()

Interpolates linearly between two values. Both addresses need to be cast to the appropriate data type.

参数

[in,out]	data1	The address of the first value. The value will be overwritten with the result.
[in]	data2	The address of the second value.
[in]	blend	The blend percentage [0.0..blend..1.0]

◆  InterpolateInOutline()

Interpolates a value in the outline using the specified weights. The addresses in data and outline need to be cast to the appropriate data type.

参数

[in,out]	data	The address of the value. The value will be overwritten with the result.
[in]	outline	The outline data used to perform the interpolation.
[in]	weights	Weights to be used for the interpolation, represent the interpolation distance from each outline edge.

◆  GetDefaultValue()

Returns the default value for this attribute. The caller owns the passed pointer.

参数

[out]

data

A pointer filled with the default value.

◆  AtrLessThen()

Compares two data values for "less than". In most cases this returns the MeshAttributeClassInterface::GetDataType() Compare() but the developer is free to customize comparison if needed.

参数

[in]	data1	First data to compare.
[in]	data2	Second data to compare.

返回

True if the content of data1 is smaller then data2.

◆  AtrIsEqual()

Compares two data values for equality. In most of cases just returns the MeshAttributeClassInterface::GetDataType() IsEqual() but the developer is free to customize comparison if needed.

参数

[in]	data1	First data to compare.
[in]	data2	Second data to compare.

返回

True if the content of data1 is equal to data2.

◆  AtrAdd()

Defines how to add two data values.

参数

[in,out]	data1	The address of the first value. The value will be overwritten with the result.
[in]	data2	The address of the second value.

◆  AtrSubstract()

Defines how to subtract two data values.

参数

[in,out]	data1	The address of the first value. The value will be overwritten with the result.
[in]	data2	The address of the second value.

◆  AtrMultiply() [1/2]

Defines how to multiply two data values.

参数

[in,out]	data1	The address of the first value. The value will be overwritten with the result.
[in]	data2	The address of the second value.

◆  AtrMultiply() [2/2]

Defines how to multiply a data value by a float value.

参数

[in,out]	data	The address of the data value. The value will be overwritten with the result.
[in]	value	The value to be used for the multiplication.

◆  AtrDivide() [1/2]

Defines how to divide two data values.

参数

[in,out]	data1	The address of the first value. The value will be overwritten with the result.
[in]	data2	The address of the second value.

◆  AtrDivide() [2/2]

Defines how to divide a data value by a float value.

参数

[in,out]	data	The address of the data value. The value will be overwritten with the result.
[in]	value	The value to be used for the division.

◆  AtrToString()

Returns a readable string of the content of a data pointer.

参数

[in,out]	data	The address of the data value.
[in]	formatStatement	Nullptr or additional formatting instructions. Currently no additional formatting instructions are supported.

返回

The converted result.
