vector< unsigned short >::type IndexMap
Definition: OgreMesh.h:108
Class to manage the scene object rendering queue.
Defines a part of a complete mesh.
Definition: OgreSubMesh.h:63
Summary class collecting together vertex source information.
size_t calculateMaxNumInstances(const SubMesh *baseSubMesh, uint16 flags) const
virtual void _updateRenderQueue(RenderQueue *queue)
Overloaded to visibility on a per unit basis and finally updated the vertex texture.
virtual size_t updateInstanceDataBuffer(bool isFirstTime, Camera *currentCamera)
updates the vertex buffer containing the per instance data
void createVertexSemantics(VertexData *thisVertexData, VertexData *baseVertexData, const HWBoneIdxVec &hwBoneIdx, const HWBoneWgtVec &hwBoneWgt)
Creates 2 TEXCOORD semantics that will be used to sample the vertex texture.
void setupVertices(const SubMesh *baseSubMesh)
virtual bool checkSubMeshCompatibility(const SubMesh *baseSubMesh)
Returns false on errors that would prevent building this batch from the given submesh.
vector< float >::type HWBoneWgtVec
bool isStatic() const
Returns true if this batch was set as static.
void setStaticAndUpdate(bool bStatic)
size_t updateVertexTexture(Camera *currentCamera)
Keeps filling the VTF with world matrix data.
vector< uint8 >::type HWBoneIdxVec
virtual bool matricesTogetherPerRow() const
Affects VTF texture's width dimension.
void _boundsDirty(void)
Overloaded so that we don't perform needless updates when in static mode.
