Module spin_cube 

The example’s own scene: a spinning, textured cube with two egui panels.

This is the scene the windowed example always showed. Its snapshot test is the workspace’s CI check against spin_cube.webp: 30 frames at the default window size, so a rendering regression fails the build.

Structs

CameraOrbit 🔒

How far the camera has been dragged around the cube, in radians.

DragFrom 🔒

The pointer the drag is following, and where it was at the previous move.

FrameCount 🔒

Counts the frames drawn, for the panel’s readout.

Spin 🔒

A behaviour component: the cube turns by radians_per_second.

SpinReset 🔒

Set by the panel’s button, read once by the frame loop.

SpinState 🔒

The state of the spin, shared between the panel, the pointer behaviour and the frame loop.

TexturedCube 🔒

The scene’s one visible object: a textured cube turned by the frame loop.

Constants

ORBIT_ELEVATION 🔒

How high above the horizon the camera starts, in radians.

ORBIT_RADIUS 🔒

How far from the target the camera orbits, in world units.

ORBIT_TARGET 🔒

The point the camera looks at, in world units.

SAMPLE_COUNT

The number of samples every frame is rendered with.

SPIN 🔒

How fast the cube spins, in radians per second.

Statics

SCENE

The scene: a spinning cube at the example’s default window size, whose snapshot test verifies spin_cube.webp.

Functions

build 🔒

Build the cube scene’s world content.

checkerboard 🔒

A size x size checkerboard base-color texture.

orbit_camera 🔒

A camera orbiting ORBIT_TARGET at azimuth and elevation, in radians.
