CGlRenderNode A unit of renderable geometry and the associated state information needed for rendering...

CGlVboNode A rendering node that holds a vertex buffer object.

class CRgbaColor provides a simple abstraction for managing colors.

static const Colors colors

CIRef< IVboGeom > m_VBOGeom

subclass for vboset representing point, line, tri or quad geometry

CIRef< IVboGeom > GetVBOGeom()

virtual void x_Render()

Does actual rendering work.

void SetVBOGeom(IVboGeom *geom)

Set/get geometry object. These can be shared between nodes.

size_t GetVertexCount() const

GLenum GetDrawMode() const

Return the current drawing mode (e.g.

#define END_NCBI_SCOPE

End previously defined NCBI scope.

#define BEGIN_NCBI_SCOPE

Define ncbi namespace.

#define NCBI_GUIOPENGL_EXPORT

Standard mechanism to include OpenGL headers for all platforms.
