color_texture()

virtual texture_ptr_type gdk::graphics::null_texture_camera::color_texture ( ) const

nodiscardoverridevirtual

the texture the camera draws colour into

Implements gdk::graphics::texture_camera.

depth_texture()

virtual texture_ptr_type gdk::graphics::null_texture_camera::depth_texture ( ) const

nodiscardoverridevirtual

the texture the camera draws depth into

Exceptions

gdk::graphics::exception

where the device cannot sample depth

Implements gdk::graphics::texture_camera.

set_clear_color()

virtual void gdk::graphics::null_texture_camera::set_clear_color ( const color & acolor )

overridevirtual

sets the clear color, used to fill color buffer after it is cleared.

Implements gdk::graphics::camera.

set_clear_mode()

virtual void gdk::graphics::null_texture_camera::set_clear_mode ( const clear_mode aClearMode )

overridevirtual

clear mode decides which buffers to clear. see enum

Implements gdk::graphics::camera.

set_orthographic_projection()

virtual void gdk::graphics::null_texture_camera::set_orthographic_projection ( const vector2_type & aOrthographicSize, const floating_point_type aNearClippingPlane, const floating_point_type aFarClippingPlane, const floating_point_type aViewportAspectRatio )

overridevirtual

use an orthographic projection with the given view volume aOrthographicSize is the full extent of the volume, not its half extents

Implements gdk::graphics::camera.

set_perspective_projection() [1/2]

virtual void gdk::graphics::null_texture_camera::set_perspective_projection ( const floating_point_type aFieldOfView, const floating_point_type aNearClippingPlane, const floating_point_type aFarClippingPlane, const floating_point_type aViewportAspectRatio )

overridevirtual

use a perspective projection with the given view volume

Parameters

aFieldOfView	vertical field of view, in radians
aNearClippingPlane	distance to the near plane; must be > 0
aFarClippingPlane	distance to the far plane; must be > aNearClippingPlane
aViewportAspectRatio	width divided by height

Implements gdk::graphics::camera.

set_perspective_projection() [2/2]

virtual void gdk::graphics::null_texture_camera::set_perspective_projection ( const floating_point_type aFieldOfView, const floating_point_type aNearClippingPlane, const floating_point_type aFarClippingPlane, const floating_point_type aViewportAspectRatio, const vector2_type & aShift )

overridevirtual

use a perspective projection whose window is off the view's axis: an asymmetric frustum, as an eye of a stereo pair sees a screen both eyes converge on, or a panel of a tiled display sees its share

Parameters

aShift

how far the window's centre is from the axis, as a share of the window's half extents: {0, 0} is the symmetric projection above; {0.25, 0} moves the window a quarter of its half width to the right, so what is on the axis is drawn that far left of the centre

Implements gdk::graphics::camera.

set_transform() [1/2]

virtual void gdk::graphics::null_texture_camera::set_transform ( const matrix4x4_type & aMatrix )

overridevirtual

sets the camera's world and view matrix

Implements gdk::graphics::camera.

set_transform() [2/2]

virtual void gdk::graphics::null_texture_camera::set_transform ( const vector3_type & aWorldPos, const quaternion_type & aRotation )

overridevirtual

Implements gdk::graphics::camera.
