GMOperatorsInterfaces Interface CATICGMTopSilhouette

Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.

interface CATICGMTopSilhouette

Class defining the operator that computes the silhouette for a given body.

It follows the general frame of all operators and satisfies the smart mechanism: the input bodies are not modified. A new resulting body is created, possibly sharing data with the input bodies.

CATICGMTopSilhouette is created with the CATCGMCreateTopSilhouette global function. It must be released with the Release method after use. It is not streamable.
The result is accessed with the GetResult method. If you do not want to keep the resulting body, use the method to remove it from the geometric factory.

Method Index

o SetProjectionScreenForShadows(CATBody*,CATBoolean): Sets the operator to project shadows on a planar screen whose the normal is the projection direction.
o SetProjectionScreenForShadows(CATMathPlane&,CATBoolean): Sets the operator to project shadows on a planar screen whose the normal is the projection direction.

Methods

o SetProjectionScreenForShadows

public virtual SetProjectionScreenForShadows(		`iScreenBody`,
		`iLightSourceInFront`)

Sets the operator to project shadows on a planar screen whose the normal is the projection direction.

Parameters:

iScreenBody: The infinite or trimmed planar screen to project the shadows.
iLightSourceInFront: The side from which the light comes : This side influences the location of points on the boundary of the shadow.
TRUE if the planar normal direction shows the light source.
FALSE if the light source is behind the screen.

Returns:

o SetProjectionScreenForShadows

public virtual SetProjectionScreenForShadows(	const	`iScreenPlane`,
		`iLightSourceInFront`)

Sets the operator to project shadows on a planar screen whose the normal is the projection direction.

Parameters:

iScreenPlane: The infinite planar screen to project the shadows.
iLightSourceInFront: The side from which the light comes : This side influences the location of points on the boundary of the shadow.
TRUE if the planar normal direction shows the light source.
FALSE if the light source is behind the screen.
