Detailed Description

Combines shapes in different ways to create a new one.

To create a concrete operation, subclass Boolean and implement isTangible() and updateAttributes(). Of course, make sure to pass the right number of vertices and all the attribute names in the constructor.

---

Constructor & Destructor Documentation

Boolean	(	const Tag &	tag,
		ShapeTraits	traits
	)

Creates a new Boolean node.

Exceptions:

	Exception	if of attribute not present
	Exception	if operation attribute not present
	NodeException	if float is not signed

~Boolean

(

)

[virtual]

Deletes all the uniforms stored.

Member Function Documentation

void applyUniforms

(

int

i

)

const [protected]

Applies all the uniforms for one of the shapes.

void applyUniforms

(

)

const [protected]

Applies all the uniforms for all of the shapes.

void associate

(

)

[virtual]

Finds the group, shapes, transforms, and uniforms needed by the operation.

Exceptions:

NodeException

from Shape::associate()

Reimplemented from Shape.

Reimplemented in BooleanAnd.

void associateUniforms

(

)

[protected]

Associates all the uniforms.

void calculate

(

)

[protected]

Boolean shape is not correct and must be recalculated.

Reimplemented in BooleanXor.

void calculateExtents

(

Node *

node

)

[protected]

Traverse a subtree and calculate extents for each shape.

void calculateExtents

(

)

[protected]

Traverse the group and calculate extents for each shape.

void calculateOverlap

(

)

[protected]

Find where the shapes overlap.

void draw

(

)

const [virtual]

Only draw the boolean operation if its output is tangible.

Reimplemented from Shape.

Reimplemented in BooleanAnd, and BooleanXor.

void finalize

(

)

[virtual]

Creates the shape and finalizes all the uniforms.

Reimplemented from Shape.

void finalizeUniforms

(

)

[protected]

Suppresses then finalizes all the stored uniforms.

void findGroup

(

)

[protected]

Finds the group the Boolean should look for shapes in.

Exceptions:

NodeException

if the group named by of cannot be found.

void findShapes

(

)

[protected]

Exceptions:

NodeException

if no shapes are in group.

void findTransforms

(

)

[protected]

Finds transforms in the group and listens for changes from them.

void findUniforms

(

)

[protected]

Finds uniforms of the shapes, then copies and stores them.

bool isOverlapped

(

)

const [protected]

Determines if the shapes intersect each other using overlap attribute.

bool isSubstantial

(

const Extent &

extent

)

[static, protected]

Determines if an extent is three dimensional.

void onNodeEvent

(

NodeEvent &

event

)

[virtual]

Redo the operation when a Transformation has changed.

Reimplemented from SimpleTransformable.

string toString

(

)

const [virtual]

Returns:

string representing the node.

Reimplemented from Shape.

Reimplemented in BooleanXor.

void updateBuffer

(

)

[protected, virtual]

Only initialize all the attributes if the boolean output is tangible.

Reimplemented from Hexahedron.
