The framework call this method any time a change of instance occurs.
Implemented in NL3D::CMeshGeom. |
|
|
The framework call this method when he will render instances of this meshGeom soon.
Implemented in NL3D::CMeshGeom. |
| virtual bool NL3D::IMeshGeom::clip |
( |
const std::vector< CPlane > & |
pyramid, |
|
|
const CMatrix & |
worldMatrix |
|
) |
[inline, virtual] |
|
|
|
clip this shape with a pyramid.
the pyramid is given in world space.The world matrix of the object is given. -
Parameters:
-
| pyramid |
the clipping polytope, planes are normalized. |
| worldMatrix |
the world matrix of the instance. |
-
Returns:
-
true if the object is visible, false otherwise. The default behavior is to return true (never clipped).
Reimplemented in NL3D::CMeshGeom.

) |
[inline, virtual] |
|
|
|
When the framework succes to allocate a VBHeap space, it call this method to fill this space and compute shifted Primitive block.
-
Parameters:
-
| the |
dest VertexBuffer. NB: start to fill at dst[0] |
| indexStart |
used to shift primitive block. |
Reimplemented in NL3D::CMeshGeom.
Definition at line 195 of file mesh_geom.h. |
|
|
The framework call this method when it has done with this meshGeom.
Implemented in NL3D::CMeshGeom. |
| virtual const NLMISC::CAABBoxExt& NL3D::IMeshGeom::getBoundingBox |
( |
|
) |
const [pure virtual] |
|
|
|
get the extended axis aligned bounding box of the mesh.
Implemented in NL3D::CMeshGeom. |
| virtual uint NL3D::IMeshGeom::getNumRdrPasses |
( |
|
) |
const [pure virtual] |
|
|
|
return the number of renderPasses for this mesh.
Implemented in NL3D::CMeshGeom. |
| virtual float NL3D::IMeshGeom::getNumTriangles |
( |
float |
distance |
) |
[pure virtual] |
|
|
|
get an approximation of the number of triangles this instance will render for a fixed distance.
-
Parameters:
-
| distance |
is the distance of the shape from the eye. |
-
Returns:
-
the approximate number of triangles this instance will render at this distance. This number can be a float. The function MUST be decreasing or constant with the distance but don't have to be continus.
Implemented in NL3D::CMeshGeom. |

[inline, virtual] |
|
|
|
The framework call this method to know if the mesh can fit in VBHeap.
if yes, deriver must return mesh vertexFormat and num of vertices.

render() this meshGeom in a driver, with the specified TransformShape instance information.
NB: the meshGeom is ensured to not be skinned to a skeleton, but CMeshGeom may still have skin information.
Implemented in NL3D::CMeshGeom. |
|
|
The framework call this method to render the current renderPass, with the current instance NB: if the material is blended, DON'T render it!!

[pure virtual] |
|
|
|
render this meshGeom as a skin, with the specified TransformShape instance information (which gives the driver) NB: trans->isSkinned() is ensured to be true.
All the materials must be rendered.
Implemented in NL3D::CMeshGeom. |
| virtual bool NL3D::IMeshGeom::sortPerMaterial |
( |
|
) |
const [pure virtual] |
|
|
|
true if the sort criterion must be by material.
Else, sort per instance.
Implemented in NL3D::CMeshGeom. |
| virtual bool NL3D::IMeshGeom::supportMeshBlockRendering |

) |
const [pure virtual] |
|
|
|
true if this meshGeom support meshBlock rendering.
eg: return false if skinned/meshMorphed.
