Member Function Documentation

setColor()

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

overridevirtual

Set modulation color.

Parameters

r	Red component in [0,1].
g	Green component in [0,1].
b	Blue component in [0,1].
a	Alpha component in [0,1].

Implements OpenGL::Pipeline.

setProjectionMatrix()

void OpenGL::ShaderPipeline::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::ShaderPipeline::activateInternal ( )

overrideprotectedvirtual

Activate the pipeline.

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

Reimplemented from OpenGL::Pipeline.

deactivateInternal()

void OpenGL::ShaderPipeline::deactivateInternal ( )

overrideprotectedvirtual

Deactivate the pipeline.

Reimplemented from OpenGL::Pipeline.

drawTextureInternal()

void OpenGL::ShaderPipeline::drawTextureInternal ( const Texture &  texture, const GLfloat *  coordinates, const GLfloat *  texcoords  )

overrideprotectedvirtual

Implements OpenGL::Pipeline.
