Cellular Cloud Node¶

class CellularCloudNode : public simul::clouds::CellularCloudGrid ¶

A basic cloud class Don’t create a CellularCloudNode directly, instead, use the derived class FastCloudNode.

Public Functions

virtual const float *GetTransformToLightspaceMatrix(unsigned axis, const platform::math::Vector3 &dir, const platform::math::Vector3 &origin, const platform::math::Vector3 &scales) const¶: Get a 4x4 matrix to transform from real space to lightspace.

virtual const float *GetTransformLightspaceToCloudspaceMatrix(unsigned axis, const platform::math::Vector3 &dir, const platform::math::Vector3 &origin, const platform::math::Vector3 &scales, float cloud_base_z, float w, float h) const¶: Get a 4x4 matrix to transform from lightspace to cloudspace.

platform::math::NoiseInterface *GetNoiseInterface()¶: Get a pointer to the noise memory interface.

inline void SetRecalculate(bool r)¶: Recalculate and reinitialise the cloud grid with updated values.

void SetRelight()¶: Force relighting of the volume. Usually unnecessary.

inline virtual bool NeedsRelight() const¶: Have properties changed that cause relighting to be necessary - either the light has moved or the cloud density grid has changed.

virtual int GetGenerationNumber() const¶: A number that is changed every time the clouds are regenerated.

virtual void GetExtents(platform::math::Vector3 &X1, platform::math::Vector3 &X2, float cloud_base_z, float w, float h) const¶: Get the physical extents of the cloud volume in the x, y and z directions.

virtual platform::math::Vector3 GetOrigin(platform::math::Vector3 windOffset, float cloud_base_z, float w) const¶: Get the effective origin in world co-ordinates, including wind offsets:

std::ostream &StreamOut(std::ostream &os) const¶: Stream/save to the std::osteam os.

std::istream &StreamIn(std::istream &is)¶: Stream/load from the std::isteam is.

std::ostream &StateStreamOut(std::ostream &os) const¶: Stream/save to the std::osteam os.

std::istream &StateStreamIn(std::istream &is)¶: Stream/load from the std::isteam is.

virtual unsigned GetMemoryUsage() const¶: Get the amount of memory used by this class instance, in bytes.
