Member Function Documentation

◆ getFirstCommandToDraw()

unsigned int osg::DrawElementsIndirect::getFirstCommandToDraw ( ) const

inline

get offset of the first command in the IndirectCommandDrawArrays

References _firstCommand.

◆ getIndirectCommandArray() [1/2]

IndirectCommandDrawElements * osg::DrawElementsIndirect::getIndirectCommandArray ( )

inline

get command array of this indirect primitive set

References _indirectCommandArray.

const IndirectCommandDrawElements * osg::DrawElementsIndirect::getIndirectCommandArray ( ) const

inline

References _indirectCommandArray.

◆ getNumPrimitives()

virtual unsigned int osg::DrawElementsIndirect::getNumPrimitives ( ) const

pure virtual

Reimplemented from osg::PrimitiveSet.

Implemented in osg::DrawElementsIndirectUByte, osg::DrawElementsIndirectUInt, osg::DrawElementsIndirectUShort, osg::MultiDrawElementsIndirectUByte, osg::MultiDrawElementsIndirectUInt, and osg::MultiDrawElementsIndirectUShort.

◆ getStride()

GLsizei osg::DrawElementsIndirect::getStride ( ) const

inline

stride (to set if you use custom CommandArray)

References _stride.

◆ setFirstCommandToDraw()

void osg::DrawElementsIndirect::setFirstCommandToDraw ( unsigned int i )

inline

set offset of the first command to draw in the IndirectCommandDrawArrays

Further methods are for advanced DI when you plan to use your own IndirectCommandElement (stride) or if you want to draw a particular command index of the IndirectCommandElement(FirstCommandToDraw)

References _firstCommand.

◆ setIndirectCommandArray()

void osg::DrawElementsIndirect::setIndirectCommandArray ( IndirectCommandDrawElements * idc )

inline

set command array of this indirect primitive set
