◆ setColor()

void OpenGL::FixedPipeline::setColor ( GLfloat  r,
GLfloat  g,
GLfloat  b,
GLfloat  a 
)
overridevirtual

Set modulation color.

Parameters
rRed component in [0,1].
gGreen component in [0,1].
bBlue component in [0,1].
aAlpha component in [0,1].

Implements OpenGL::Pipeline.

◆ setProjectionMatrix()

void OpenGL::FixedPipeline::setProjectionMatrix ( const Math::Matrix4 &  projectionMatrix)
overridevirtual

Set the projection matrix.

This is intended to be only ever be used by Framebuffer subclasses.

Implements OpenGL::Pipeline.

◆ activateInternal()

void OpenGL::FixedPipeline::activateInternal ( )
overrideprotectedvirtual

Activate the pipeline.

This sets the OpenGL state to make use of drawing with the given OpenGL pipeline.

Reimplemented from OpenGL::Pipeline.
