cee::geo::PartSettings

class PartSettings : public RefCountedObject

Part settings represents how to draw a part and its associated part data.

Each part can have any number of effects. Add effects for manipulating how the part data should be drawn. These effect are added, queried and retrieved from the parts part settings.

• It is not allowed to enter an effect not applicable for the associated part data.
• Default effects are used if not provided, where needed.
• Effects are organized in a stack and the system will use the first applicable unused effect type found, ignoring any other effects in the same group further down the stack.

Public Functions

PartSettings()

Constructs an empty part settings.

void setVisible(bool visible)

Shows or hides the whole part.

bool visible() const

Returns true if the part is drawn.

void setIntersectable(bool intersectable)

Sets if the part should be “selectable” or not when doing rayIntersect/regionIntersect.

The default is true. If this is set to false, this part will not be hit by the GeometryModel::rayIntersect() or GeometryModel::regionIntersect() methods.

This is useful if you only want the user to be able to pick/select parts of the model.

bool intersectable() const

Returns true if the part is “selectable” (default), i.e.

considered in rayIntersect() or regionIntersect().

If this method returns false, the part will not be hit in GeometryModel::rayIntersect() or GeometryModel::regionIntersect().

size_t effectCount() const

Returns the number of associated effects.

size_t effectIndex(const Effect *effect) const

Returns index of the given effect.

Effect *effect(size_t index)

Returns the effect at the given index.

const Effect *effect(size_t index) const

Returns the effect at the given index.

void addEffect(Effect *effect)

Adds an effect.

void removeEffect(Effect *effect)

Removes effect from part.

Warning

Effect must already be present in the part settings

void removeAllEffects()

Removes all associated effects.

template<typename T>
const T *activeEffectOfType() const

Returns the active (last inserted/top of stack) effect of the given type T, or NULL if no effect of that type was found.

template<typename T>
T *activeEffectOfType()

Returns the active (last inserted/top of stack) effect of the given type T, or NULL if no effect of that type was found.

template<typename T>
void removeAllEffectsOfType()
