class HPS::TransparencyKit : public HPS::Kit
The HPS::TransparencyKit class is a user space object, useful for carrying a group of attribute settings related to transparency. Calling HPS::TransparencyKit::GetDefault() will return a kit with values found in this table.
Public Functions
-
virtual bool Empty() const
Indicates whether this object has any values set on it.
- Returns
true if no values are set on this object, false otherwise.

true if the objects are equivalent, false otherwise.
-
inline virtual HPS::Type ObjectType() const
This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).
- Returns
The declared type of the object in question, which may differ from the true, underlying type.
-
bool operator!=(TransparencyKit const &in_kit) const
Check if the source TransparencyKit is not equivalent to this object.
- Parameters
in_kit – The source TransparencyKit to compare to this object.
- Returns
true if the objects are not equivalent, false otherwise.
-
TransparencyKit &operator=(TransparencyKit &&in_that)
The move assignment operator transfers the underlying impl of the rvalue reference to this TransparencyKit thereby avoiding a copy.
- Parameters
in_that – An rvalue reference to an TransparencyKit to take the impl from.
- Returns
A reference to this TransparencyKit.
-
TransparencyKit &operator=(TransparencyKit const &in_kit)
Copies the source TransparencyKit into this object.

in_kit – The source TransparencyKit to copy.
- Returns
A reference to this object.
-
bool operator==(TransparencyKit const &in_kit) const
Check if the source TransparencyKit is equivalent to this object.
- Parameters
in_kit – The source TransparencyKit to compare to this object.

void Set(TransparencyKit const &in_kit)
Copies all settings from the source TransparencyKit into this object.

TransparencyKit &SetAlgorithm(Transparency::Algorithm in_algorithm)
Sets the algorithm to use when calculating transparency.
- Parameters
in_algorithm – The algorithm to use.
- Returns
a reference to this object.
-
TransparencyKit &SetDepthPeelingLayers(unsigned int in_layers)
Sets the number of layers to use when performing depth peeling. Ignored in other transparency methods.
Warning
This setting will be limited by the depth peeling layer count set at the containing window / subwindow. If the count is lower than the containing window’s count, excess render passes will be omitted.
- Parameters
in_layers – The number of layers to use when performing depth peeling.
- Returns
a reference to this object.
-
TransparencyKit &SetDepthPeelingMinimumArea(float in_area, Transparency::AreaUnits in_units)
Sets the amount of the screen a layer needs to occupy in order to process another layer when performing depth peeling. Ignored in other transparency methods.
- Parameters
in_area – The amount of the screen a layer needs to occupy in order to process another layer.
in_units – The units of the minimum area.
- Returns
a reference to this object.
-
TransparencyKit &SetDepthPeelingPreference(Transparency::Preference in_preference)
Specifies whether quality or performance should be favored when performing depth peeling. Ignored in other transparency methods.
- Parameters
in_perference – The desired preference setting.
- Returns
a reference to this object.
-
TransparencyKit &SetDepthWriting(bool in_state)
Controls whether transparent geometry should write into the Z-buffer. Applies only when the transparency algorithm is NoSorting, ZSortNicest, or ZSortFastest.
- Parameters
in_state – Whether transparent geometry should write into the Z-buffer.
- Returns
a reference to this object.
-
TransparencyKit &SetMethod(Transparency::Method in_style)
Sets the method to use when blending transparent geometry.
- Parameters
in_style – The method to use when blending transparent geometry.
- Returns
a reference to this object.
-
void Show(TransparencyKit &out_kit) const
Copies all settings from this TransparencyKit into the given TransparencyKit.
- Parameters
out_kit – The TransparencyKit to populate with the contents of this object.
-
bool ShowAlgorithm(Transparency::Algorithm &out_algorithm) const
Shows the algorithm to use when calculating transparency.
- Parameters
out_algorithm – The algorithm to use.
- Returns
true if the setting is valid, false otherwise.
-
bool ShowDepthPeelingLayers(unsigned int &out_layers) const
Shows the number of layers to use when performing depth peeling.
- Parameters
out_layers – The number of layers to use when performing depth peeling.
- Returns
true if the setting is valid, false otherwise.
-
bool ShowDepthPeelingMinimumArea(float &out_area, Transparency::AreaUnits &out_units) const
Shows the amount of the screen a layer needs to occupy in order to process another layer when performing depth peeling.
- Parameters
out_area – The amount of the screen a layer needs to occupy in order to process another layer.
out_units – The units of the minimum area.
- Returns
true if the setting is valid, false otherwise.
-
bool ShowDepthPeelingPreference(Transparency::Preference &out_preference) const
Shows the depth peeling performance setting.
- Parameters
out_preference – Whether quality or performance should be favored when performing depth peeling.
- Returns
true if the setting is valid, false otherwise.
-
bool ShowDepthWriting(bool &out_state) const
Shows whether transparent geometry should write into the Z-buffer.
- Parameters
out_state – Whether transparent geometry should write into the Z-buffer.

- Returns
true if the setting is valid, false otherwise.
-
TransparencyKit()
Initializes an empty kit.
-
TransparencyKit(TransparencyKit &&in_that)
The move constructor creates a TransparencyKit by transferring the underlying impl of the rvalue reference to this TransparencyKit thereby avoiding a copy and allocation.

Public Static Functions
-
static TransparencyKit GetDefault()
