Member Function Documentation

◆ BeginDrawing()

virtual void KIGFX::GPU_MANAGER::BeginDrawing ( )
pure virtual

Prepare the stored data to be drawn.

Implemented in KIGFX::GPU_CACHED_MANAGER, and KIGFX::GPU_NONCACHED_MANAGER.

◆ DrawIndices()

virtual void KIGFX::GPU_MANAGER::DrawIndices ( const VERTEX_ITEM aItem)
pure virtual

Make the GPU draw given range of vertices.

Parameters
aOffsetis the beginning of the range.
aSizeis the number of vertices to be drawn.

Implemented in KIGFX::GPU_CACHED_MANAGER, and KIGFX::GPU_NONCACHED_MANAGER.

◆ EnableDepthTest()

void GPU_MANAGER::EnableDepthTest ( bool  aEnabled)

References m_enableDepthTest.

◆ EndDrawing()

virtual void KIGFX::GPU_MANAGER::EndDrawing ( )
pure virtual

Clear the container after drawing routines.

Implemented in KIGFX::GPU_CACHED_MANAGER, and KIGFX::GPU_NONCACHED_MANAGER.

◆ MakeManager()

GPU_MANAGER * GPU_MANAGER::MakeManager ( VERTEX_CONTAINER aContainer)
