DtIndirectModelInfo& makVrv::DtIndirectModelInfo::operator= ( const DtIndirectModelInfo & )

delete

not allowed

virtual void makVrv::DtIndirectModelInfo::unloadBuffers ( )

virtual

unload gl buffers make gl buffers non-resident and add them to the delete manager

virtual bool makVrv::DtIndirectModelInfo::buffersUploadedToGpu ( ) const

virtual

Is all buffer data completely uploaded to the GPU?

virtual bool makVrv::DtIndirectModelInfo::processGpuBufferUploads ( unsigned int & uploadedMemory )

virtual

Processes any remaining gpu buffer uploads. Returns true if the model data is still in the process of being uploaded to the gpu.

Parameters

uploadedMemory The amount of memory uploaded to the GPU. (modified by this function)

virtual void makVrv::DtIndirectModelInfo::texturesSet ( std::map< const DtIndirectTexturePrototype *, int > & texturesSet ) const

virtual

get the set of textures (diffuse + effect textures) that this model refers to

virtual void makVrv::DtIndirectModelInfo::addUser ( const DtGpuCulling * user )

virtual

gpu culling is the only 'user' of the model info since it uses the bindless address of the buffers and textures of the model multiple gpu cullings (and hence indirect geometries) can refer to the same model info

virtual void makVrv::DtIndirectModelInfo::removeUser ( const DtGpuCulling * user )

virtual

gpu culling is the only 'user' of the model info since it uses the bindless address of the buffers and textures of the model multiple gpu cullings (and hence indirect geometries) can refer to the same model info

virtual void makVrv::DtIndirectModelInfo::computeMaxTextureResolution ( const DtIndirectLimitTextureStrategy & limitStrategy )

virtual

update the max texture resolution in x and y for all textures of a given model should be done when the model is finalized. Also, excludes the excluded textures from the max computation, per the specified strategy

virtual const BindlessPtrNV& makVrv::DtIndirectModelInfo::vertexBufferBindless ( int index ) const

virtual

bindless vertex buffer

virtual const BindlessPtrNV& makVrv::DtIndirectModelInfo::additionalBufferBindless ( int index ) const

virtual

bindless additional attributes buffer

virtual const BindlessPtrNV& makVrv::DtIndirectModelInfo::indexBufferBindless ( int index ) const

virtual

bindless index buffer

virtual int makVrv::DtIndirectModelInfo::numSubGeometries ( ) const

virtual

number of sub goes

virtual int makVrv::DtIndirectModelInfo::maxCoords ( int index ) const

virtual

The max texture coordinates unit/number of the texture coordinate sets.

virtual int makVrv::DtIndirectModelInfo::numVertices ( int index ) const

virtual

The num of vertices.

virtual int makVrv::DtIndirectModelInfo::numIndices ( int index ) const

virtual

The num of indices.

virtual void makVrv::DtIndirectModelInfo::addSubGeometry ( DtIndirectModelSubGeometry * modelSubGeometry )

virtual

Don't use directly Added only by aggregator. This will transfer ownership of the sub geo/ (ie, the model info will handle the lifetime/deletion of this subgeo)

virtual DtIndirectModelSubGeometry* makVrv::DtIndirectModelInfo::subGeometry ( int index ) const

virtual

Don't use directly. Used only by DtIndirectModelInfoContainer::copyData to copy data: sub geo <- osg.

virtual void makVrv::DtIndirectModelInfo::promoteDataFromSubGeosToMe ( )

virtual

Don't use directly. Used only by DtIndirectModelInfoContainer. Promote data from sub geos into me. The sub geos can then be deleted.

virtual void makVrv::DtIndirectModelInfo::resetGpuUploads ( )

protectedvirtual

Resets information associated with gpu uploads. Marks the state of the model buffers as not uploaded to gpu.

virtual bool makVrv::DtIndirectModelInfo::isDefaultTexture ( const DtIndirectTexturePrototype * texture ) const

protectedvirtual

whether a texture is the default white texture

virtual bool makVrv::DtIndirectModelInfo::glBuffersContainAnyData ( ) const

protectedvirtual

Returns true if any gl buffer data has been loaded partially or fully.

virtual void makVrv::DtIndirectModelInfo::releaseGLObjects ( osg::State * state )

protectedvirtual

release gl objects

virtual void makVrv::DtIndirectModelInfo::createIndirectBuffers ( )

protectedvirtual

internal. create the indirect buffers

virtual void makVrv::DtIndirectModelInfo::deleteIndirectBuffers ( )

protectedvirtual

internal. delete the indirect buffers

virtual void makVrv::DtIndirectModelInfo::computeChunkUploadSize	(	unsigned int &	desiredUploadSize,
		unsigned int &	maxUploadSize
	)		const

protectedvirtual

internal. computes the the desired upload size for each chunk of data that is uploaded to the GPU. Rather than updating the entire buffer at once, the buffer updates are split into chunks to improve GPU driver interaction.

Parameters

desiredUploadSize	the chunk size
maxUploadSize	the maximum chunk size

virtual void makVrv::DtIndirectModelInfo::prepareToUploadGpuDataForBuffer	(	DtGlBuffer &	buffer,
		std::vector< uint8_t > &	stagingData
	)

protectedvirtual

internal. prepares information about chunks of data that will be uploaded to the gpu for a given buffer

virtual void makVrv::DtIndirectModelInfo::prepareToUploadGpuData ( )

protectedvirtual

internal. prepares information about chunks of data that will be uploaded to the gpu for all buffers

virtual void makVrv::DtIndirectModelInfo::updateBindlessPointers ( )

protectedvirtual

internal. update the bindless pointers with current buffer data
