Member Function Documentation

◆ GetIndexCount()

unsigned Urho3D::IndexBuffer::GetIndexCount ( ) const
inline

Return number of indices.

◆ GetIndexSize()

unsigned Urho3D::IndexBuffer::GetIndexSize ( ) const
inline

Return index size in bytes.

◆ IsDynamic()

bool Urho3D::IndexBuffer::IsDynamic ( ) const
inline

Return whether is dynamic.

◆ SetShadowed()

void Urho3D::IndexBuffer::SetShadowed ( bool  enable)

Enable shadowing in CPU memory. Shadowing is forced on if the graphics subsystem does not exist.
