CGlState Class to encapsulate Rendering state so that a set of user-selected GL state options can be ...

void SkipTarget(ERenderTarget target, bool skip)

Turn off visibility for individual render targets.

void SetDefaultPosition()

Set 1 transformation and have it be the identity matrix.

virtual void Render()

Set state and call x_Render() to render geometry.

CMatrix4< float > GetTransformedPosition(size_t idx)

return the position with rotation and pixel offset baked in

IRender & GetGl()

convenience function for getting current render manager

CVect2< TModelUnit > GetScaleFactor() const

CVect2< float > m_PixelOffset

Pixel offset to apply to object.

vector< CMatrix4< float > > m_Positions

Set of positions (transformations) at which to render this node.

void SetPosition(const CMatrix4< float > &mat)

Set 1 transformation and have it be "mat".

virtual void x_Render()

Does actual rendering work.

void SetState(CGlState *state)

Set/get current OpenGL state.

CRef< CGlState > m_State

OpenGL state.

void MakeCurrent(ERenderTarget target)

Set current options.

float m_RotAngleZ

Optional rotation angle to rotate object around Z axis.

ERenderTarget

Different api levels based on information from OpenGL driver.

virtual ERenderTarget GetApi()=0

vector< ERenderTarget > m_SkippedTargets

Set of rendering targets for which this node will not be rendered even if m_Visible is true.

bool IsSkipped(ERenderTarget target) const

bool GetScaleInvarient() const

void Reset(void)

Reset reference object.

TObjectType & GetNCObject(void) const

Get object.

#define END_NCBI_SCOPE

End previously defined NCBI scope.

#define BEGIN_NCBI_SCOPE

Define ncbi namespace.
