GeometryClass Common Properties, Operators, and Methods

The mesh operations underlying the Boolean Compound Object in 3ds Max are accessible in MAXScript. They appear as operators (+, -, *) that you can apply to any two scene objects that are convertible to meshes. These objects are all GeometryClass objects with the exception of the particle systems.

The operators are:

<node1> + <node2>

Returns the union of node1 and node2

<node1> - <node2>

Returns the subtraction of node2 from node1

<node1> * <node2>

Returns the intersection of node1 and node2

Example:

$foo - $baz

$sphere01 + $sphere02 + $sphere03 + $sphere04

The Boolean operators change the first operand to be the result of the operation and leave the second operand untouched. So, in the first example, the $foo node is changed to an Editable Mesh object containing the result of the difference operation. In the second example, $sphere01 is successively unioned with each of the other spheres - $sphere01 contains the compound result and the other spheres are left standing.

Note

Unlike the Boolean compound object in 3ds Max, this operation destructively modifies the first operand - you cannot retrieve the original first operand after the Boolean operation is performed. You can effectively keep the first operand by using a copy function,

For example

result = (copy $foo) - $baz

will put a modified copy of $foo into the variable result, leaving the original $foo unchanged.

GetTriMeshFaceCount <node>

Returns an array of two integers - the face count and the vertex count of the TriMesh on top of the modifier stack.

Boolean2 : GeometryClass

Constructor

boolObj.createBooleanObject <operand_A> [ <operand_B> <add_method> <mat_method> ]

Creates a Boolean2 object using node <operand_A> and an optional node <operand_B>. <add_method> specifies how <operand_B> is to be used as follows:

1 - instance(Экземпляр), operand is an instance of the original node.
В операции принимает участие экземпляр второго объекта.

2 - reference(Ссылка), operand is a reference to original node.
В операции принимает участие ссылка  на второй объект.

3 - copy(скопировать),operand is a copy of original node .
В операции участвует копия второго обекта.Сам Обьект остается при этом без изменения.

4 - move(Переместить),original node should be deleted .
operand_B пропадает после выполнения операции.

<mat_method> specifies how the materials of the two operands are to be handled as follows:

1 - combines materials without changing them or the ID's

2 - matches ID's to materials, then combines materials

3 - matches materials to ID's, then combines them

4 - discards original material, uses new node's instead

5 - discards new node's material, uses original

Properties

The following properties are available only after the boolean2 object has been created. The values shown for the properties are those for a boolean2 object created from two spheres. The operand transforms are in the local coordinate system of the boolean2 object.

<bool_obj>.Sphere02 SubAnim default: SubAnim:Sphere02

<bool_obj>.Operand_A_Transform SubAnim default: SubAnim:Operand_A_Transform

<bool_obj>.Sphere01 SubAnim default: SubAnim:Sphere01

<bool_obj>.Operand_B_Transform SubAnim default: SubAnim:Operand_B_Transform

Methods

boolObj.setOperandB <bool_obj> <operand_B> <add_method> <mat_method>

sets operand B. The values for <add_method> and <mat_method> are describe above.

boolObj.getOperandSel <bool_obj> <integer>

boolObj.setOperandSel <bool_obj> <integer> <boolean>

these methods get and set whether operand_A and operand_B are selected in the Operands list. <integer> = 1 - operand_A, 2 - operand_B

boolObj.getBoolOp <bool_obj>

boolObj.setBoolOp <bool_obj> <integer>

these methods get and set the boolean Operation Type. Valid values are:

1 - Union(Объединение)-
Результирующий обьект ,полученный объединение  двух объектов,содержит все точки двух исходных объектов-орерандов,за исключением общих точек.

2 - Intersection(Пересечение)
Объект ,полученный в результе операции пересечения ,содержит только те точки ,которые являются общими для
двух исходных объектов.

3 - Subtraction(Вычетания) (A-B)

4 - Subtraction (Вычетания)(B-A)

5 - Cut

boolObj.getBoolCutType <bool_obj>

boolObj.setBoolCutType <bool_obj> <integer>

these methods get and set the boolean Cut Type. The value for this property only has an effect if the Operation Type is Cut. The Cut Types are:

1 - Refine

2 - Split

3 - Remove Inside

4 - Remove Outside

boolObj.getDisplayResult <bool_obj>

boolObj.setDisplayResult <bool_obj> <boolean>

these methods get and set whether Results or Operands are displayed. If true, Result is displayed. If false, Operands are displayed.

boolObj.getShowHiddenOps <bool_obj>

boolObj.setShowHiddenOps <bool_obj> <boolean>

these methods get and set whether Results + Hidden Operands are displayed. If true, Results + Hidden Operands are displayed. If false, the Results or Operands as specified using boolObj.SetDisplayResult() are displayed.

boolObj.getUpdateMode <bool_obj>

boolObj.setUpdateMode <bool_obj> <integer>

these methods get and set the Update mode as follows:

1 - Always

2 - When Rendering

3 - Manually

boolObj.getOptimize <bool_obj>

boolObj.setOptimize <bool_obj> <boolean>

4 - move(Переместить),original node should be deleted .
operand_B пропадает после выполнения операции.

<mat_method> specifies how the materials of the two operands are to be handled as follows:

1 - combines materials without changing them or the ID's

2 - matches ID's to materials, then combines materials

3 - matches materials to ID's, then combines them
