madgui.survey.gl_widget module

Contains a OpenGL widget to display a static scene.

Classes

GLWidget(create_items, *args, **kwargs)

OpenGL widget that shows a static 3D scene, allowing the observer to freely move and look around.

ambient_color = array([0.1, 0.1, 0.1], dtype=float32)

background_color = array([0.6, 0.6, 0.6], dtype=float32)

camera_speed = 1

closeEvent(event)

Free items.

create_scene()

Fetch new items from the given callable.

create_shader_program()

Create simple program with generic fragment/vertex shaders used to render objects with a simple ambient+diffuse lighting model.

diffuse_color = array([1., 1., 1.], dtype=float32)

free()

Free all items.

hideEvent(event)

Stop scene updates (camera movement).

initializeGL()

Called after first creating a valid OpenGL context. Creates shader program, sets up camera and creates an initial scene.

keyPressEvent(event)

Maintain a list of pressed keys for camera movement.

keyReleaseEvent(event)

Maintain a list of pressed keys for camera movement.

minimumSizeHint(self) → QSize

showEvent(event)

Start scene updates (camera movement).

show_gl_info(spec, text)

Show GL version info.

sizeHint(self) → QSize

update_event()

Implement camera movement. Called regularly.

update_timer = None

wheelEvent(event)

Handle mouse wheel as zoom.

zoom_speed = 0.1
