◆ setMaximumVisibleDistance()

void LibCarna::base::ProjectionControl::setMaximumVisibleDistance ( float maximumVisibleDistance )

Sets far clipping plane distance that should be used by updateProjection.

Precondition: maximumVisibleDistance > 0

◆ setMinimumVisibleDistance()

void LibCarna::base::ProjectionControl::setMinimumVisibleDistance ( float minimumVisibleDistance )

Sets near clipping plane distance that should be used by updateProjection.

Precondition: minimumVisibleDistance >= 0

◆ setViewportHeight()

void LibCarna::base::ProjectionControl::setViewportHeight ( unsigned int height )

Sets the height of the viewport updateProjection should create projection matrices for.

Precondition: height > 0

◆ setViewportWidth()

void LibCarna::base::ProjectionControl::setViewportWidth ( unsigned int width )

Sets the width of the viewport updateProjection should create projection matrices for.

Precondition: width > 0

◆ updateProjection()

virtual void LibCarna::base::ProjectionControl::updateProjection ( math::Matrix4f & projectionMatrix ) const

pure virtual

Creates projectionMatrix based on previously set parameters.

Implemented in LibCarna::presets::OrthogonalControl, and LibCarna::presets::PerspectiveControl.
