◆ clear_scissor()
|
overridevirtual |
Implements gdk::graphics::screen_camera.
◆ set_clear_color()
|
overridevirtual |
sets the clear color, used to fill color buffer after it is cleared.
Implements gdk::graphics::camera.
◆ set_clear_mode()
|
overridevirtual |
clear mode decides which buffers to clear. see enum
Implements gdk::graphics::camera.
◆ set_orthographic_projection()
|
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]
|
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]
|
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_scissor()
|
overridevirtual |
clip this camera to a rectangle of the window without moving what it draws
Implements gdk::graphics::screen_camera.
◆ set_transform() [1/2]
|
overridevirtual |
sets the camera's world and view matrix
Implements gdk::graphics::camera.
◆ set_transform() [2/2]
|
overridevirtual |
Implements gdk::graphics::camera.
◆ set_viewport()
|
overridevirtual |
sets the normalized size and position of the viewport within the window
Viewports that meet share their edge exactly: a pixel is drawn by one of them, never by neither
Implements gdk::graphics::screen_camera.
