TP_PShapeInterface Struct Reference

#include <c4d_particles.h>

详细描述

Callback interface for nodes that register shapes.
The easiest way to create this is to implement the TP_BaseShape class:
This class is only forward-declared in c4d_particles.h , so as long as the linker approves this is fine.
范例：

class TP_BaseShape { public : TP_PShapeInterface si; TP_BaseShape () { si. base = this ; }

TP_PShape* GetShapeClone ( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, Int32 flags, AliasTrans *trn) { // ... } TP_PShape* GetShape ( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, Int32 owner_id) { // ... } BaseObject * GetShapeVirtualObjects ( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, BaseDocument *doc, HierarchyHelp *hh) { // ... } Float GetShapeScale ( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid) { // ... } void FreeShape ( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid) { // ... } };

在 TP_MSG_GET_PSHAPEINTERFACE message then simply set the passed pointer TP_PShapeInterface to &baseshape.si , for a global TP_BaseShape baseshape object that was previously created.
Thinking Particles will then call the shape functions as needed.

Member Data Documentation

◆ base

TP_BaseShape * base

Base class pointer.

◆ GetShapeClone

TP_PShapePtr (TP_BaseShape::* GetShapeClone(const TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, COPYFLAGS flags, AliasTrans *trn)

Return a clone of shape .

参数

[in]	shape	The particle shape pointer structure of the particle shape handle.
[in]	msys	The master system. The caller owns the pointed TP_MasterSystem .
[in]	pid	The particle ID: 0 <= pid < msys -> NumParticles()
[in]	flags	The flags: COPYFLAGS
[in]	trn	An alias translator for the operation. Can be nullptr . The caller owns the pointed AliasTrans .

返回: The particle shape pointer structure of the cloned particle shape. The caller owns the pointed TP_PShapePtr .

◆ GetShape

TP_PShapePtr (TP_BaseShape::* GetShape(const TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, Int32 owner_id)

Return the shape associated with shape . Normally this is the same object, so a typical implementation would be:

TP_PShapePtr GetShape ( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, Int32 owner_id) { if (shape-> Get ()-> owner_id == owner_id) return TP_ShapePtr(shape); return nullptr ; }

参数

[in]	shape	The particle shape pointer structure of the particle shape handle.
[in]	msys	The master system. The caller owns the pointed TP_MasterSystem .
[in]	pid	The particle ID: 0 <= pid < msys -> NumParticles()
[in]	owner_id	The owner ID.

返回: The particle shape pointer structure. The shape handler owns the pointed shape.

◆ GetShapeVirtualObjects

BaseObject *(TP_BaseShape::* GetShapeVirtualObjects(const TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid, BaseDocument *doc, HierarchyHelp *hh)

Return a real BaseObject for shape .

参数

[in]	shape	The particle shape pointer structure of the particle shape handle.
[in]	msys	The master system. The caller owns the pointed TP_MasterSystem .
[in]	pid	The particle ID: 0 <= pid < msys -> NumParticles()
[in]	doc	The current document. The caller owns the pointed BaseDocument .
[in]	hh	A hierarchy helper for the operation. The caller owns the pointed HierarchyHelp .

返回: The particle shape object. The particle shape handler owns the pointed object.

◆ GetShapeScale

Float (TP_BaseShape::* GetShapeScale(const TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid)

Return the scale of the particle shape.

参数

[in]	shape	The particle shape pointer structure of the particle shape handle.
[in]	msys	The master system. The caller owns the pointed TP_MasterSystem .
[in]	pid	The particle ID: 0 <= pid < msys -> NumParticles()

返回: The particle shape scale.

◆ FreeShape

void(TP_BaseShape::* FreeShape( TP_PShapePtr &shape, TP_MasterSystem *msys, Int32 pid)

Free the particle shape.

参数

[in]	shape	The particle shape pointer structure of the particle shape handle.
[in]	msys	The master system. The caller owns the pointed TP_MasterSystem .
[in]	pid	The particle ID: 0 <= pid < msys -> NumParticles()
