Member Function Documentation

◆ pixelSize()

Real fe::ext::ViewOpenGL::pixelSize	(	const SpatialVector &	a_center,
		Real	a_radius
	)		const

virtual

Estimate object's screen size.

The input is a sphere center and radius.

Reimplemented from fe::ext::ViewCommon.

References fe::ext::ViewI::camera().

◆ project()

SpatialVector fe::ext::ViewOpenGL::project	(	const SpatialVector &	a_point,
		ViewI::Projection	a_projection
	)		const

virtual

Project 3D location into screen coordinates.

By default, the current Projection determines the projection method.

Window coordinates orginate from bottom left.

Reimplemented from fe::ext::ViewCommon.

◆ scissor()

const Box2i * fe::ext::ViewOpenGL::scissor ( void ) const

virtual

Get current scissor region.

NULL indicates no scissoring.

Reimplemented from fe::ext::ViewCommon.

◆ setScissor()

void fe::ext::ViewOpenGL::setScissor ( const Box2i * a_pBox )

virtual

Clip all drawing operations to a 2D box.

Use NULL pointer to stop scissoring.

Reimplemented from fe::ext::ViewCommon.

◆ unproject()

SpatialVector fe::ext::ViewOpenGL::unproject	(	Real	a_winx,
		Real	a_winy,
		Real	a_winz,
		ViewI::Projection	a_projection
	)		const

virtual

Determine 3D location of screen coordinate.

By default, the current Projection determines the projection method.

Window coordinates orginate from bottom left.

Reimplemented from fe::ext::ViewCommon.

◆ worldSize()

Real fe::ext::ViewOpenGL::worldSize	(	const SpatialVector &	a_center,
		Real	a_pixels
	)		const

virtual

Estimate object's world size.

The input is a sphere center and projected pixel radius.

Reimplemented from fe::ext::ViewCommon.

References fe::ext::ViewI::camera().
