Base class for glyphers to be used with a MeshModelInstance.
#include <Rendering/SceneComponents/Models/glypher.h>
◆ Glypher() [1/2]
◆ Glypher() [2/2]
◆ ~Glypher()
◆ canSerialize()
bool canSerialize |
( |
| ) |
const |
|
overridevirtual |
- Returns
- True if this object can be serialized.
For objects that can be serialized, the save and load functions will be used to do the serialization. If this function returns false, both load() and save() must also return false.
Implements Serialize.
◆ clone()
◆ getCacheId()
QString getCacheId |
( |
| ) |
const |
- Returns
- A string which characterizes the parameters which affect the output of this object. It should be unique for each possible combination of the inputs. A common format is to append strings in the form ":key=value" to assist debugging, but any string that is unique for a given set of parameters is acceptable.
- Note
- The default implementation uses the serialization function save() to generate an appropriate string. Subclasses can override this function to provide a more efficient string if they so wish, since the default implementation is likely to be relatively expensive.
◆ getEnabled()
bool getEnabled |
( |
| ) |
const |
- Returns
- whether or not the texturizer is enabled.
◆ getGlyph() [1/2]
- Parameters
-
element | The element for which a glyph should be returned. |
- Returns
- A glyph object which can be used for the specified element. It is allowable for this function to return an invalid glyph to indicate that no glyph should be used for this element.
Reimplemented in RodGlypher.
◆ getGlyph() [2/2]
◆ getInterval()
int getInterval |
( |
| ) |
const |
Returns the interval between glyphs, i.e. number of nodes that remain unglyphed between each glyphed node.
- Returns
- The glypher interval.
◆ getMeshModelLibrary()
◆ isElementGlypher()
◆ isNodeGlypher()
bool isNodeGlypher |
( |
| ) |
const |
|
virtual |
◆ load()
- Parameters
-
item | Supplies the state to be loaded into this object. |
This function will load the state of this object from item. For many object types, this is most easily implemented in terms of the object's input operator (>>).
It would be reasonable for subclass implementations to assume that the data provided in item is in the same form as would have been saved from a call to save.
- Returns
- If the state of the object could not be loaded, the function returns false. A return value of true implies that the object state was successfully loaded. If canSerialize() returns false, this function must do nothing except return false as well.
Implements Serialize.
Reimplemented in RodGlypher, SphereGlypher, SquareGlypher, StreakGlypher, SuperquadricGlypher, and VectorGlypher.
◆ matchInterval() [1/2]
- Parameters
-
elt | The element to test whether it matches the interval. |
- Returns
- True if the provided element has an index that is on the interval specified in the glypher.
◆ matchInterval() [2/2]
- Parameters
-
node | The node to test whether it matches the interval. |
- Returns
- True if the provided node has an index that is on the interval specified in the glypher.
◆ operator=()
◆ save()
- Parameters
-
item | Where to save the state of this object. |
This function will serialise the object by saving it to item. For most object types, this is most easily implemented in terms of the object's output operator (<<).
It is allowable for an object to only serialize part of itself. This would be useful if the data it represents has a set of defaults and only those values different to the defaults need to be serialized. Such an implementation then needs to be careful how it handles the complimentary load member function.
- Returns
- If an object could not be serialised or if the underlying object type does not support serialisation, this function should return false. A return value of true implies that the object was successfully saved to item. If canSerialize() returns false, this function must do nothing except return false as well.
Implements Serialize.
Reimplemented in RodGlypher, SphereGlypher, SquareGlypher, StreakGlypher, SuperquadricGlypher, and VectorGlypher.
◆ setEnabled()
void setEnabled |
( |
bool |
b | ) |
|
- Parameters
-
b | whether or not to enable the texturizer. |
◆ setGlyphedModel()
- Parameters
-
model | The model about to be glyphed. |
Subclasses can reimplement this function to save internal data about the model that will be used for subsequent calls to getGlyph(). Clients are free to call this function at any time, so the subclass must keep this in mind, although it will usually only be called by a model appearance processor just before it uses the glypher to process the specified model.
NOTE: Derived classes must call this base class's method.
Reimplemented in RodGlypher, SphereGlypher, SquareGlypher, StreakGlypher, SuperquadricGlypher, and VectorGlypher.
◆ setInterval()
void setInterval |
( |
int |
interval | ) |
|
Sets the interval between glyphs, i.e. number of nodes that remain unglyphed between each glyphed node.
- Parameters
-
interval | Integer in the range [1,inf) specifying how many unglyphed nodes are to be drawn between glyphed nodes. |
◆ setIntervalStateName()
void setIntervalStateName |
( |
const QString & |
stateName | ) |
|
Specify the state name that will be used control the interval
