Module all_is_cubes::camera

Projection and view matrices, viewport and aspect ratio, visibility, raycasting into the scene, etc.

Structs

• Camera
  Defines a viewpoint in/of the world: a viewport (aspect ratio), projection matrix, and view matrix.
• Flaws
  Deficiencies of a rendering.
• GraphicsOptions
  Options for controlling rendering (not affecting gameplay except informationally).
• Layers
  A collection of values associated with each of the layers of graphics that is normally drawn (HUD on top of world, currently) by HeadlessRenderer or other renderers.
• Rendering
  Image container produced by a HeadlessRenderer.
• StandardCameras
  Bundle of inputs specifying the “standard” configuration of Cameras and other things to render an All is Cubes scene and user interface.
• UiViewState
  Specifies what to render for the UI layer in front of the world.
• Viewport
  Viewport dimensions for rendering and UI layout with the correct resolution and aspect ratio.

Enums

• AntialiasingOption
  Choices for GraphicsOptions::antialiasing.
• ExposureOption
  “Camera exposure” control: selection of algorithm to control the scaling factor from scene luminance to displayed luminance. Part of a GraphicsOptions.
• Eye
  Unit-of-measure/coordinate-system type for points/vectors in “eye space”, the space of camera-relative coordinates that are not perspective-projected.
• FogOption
  Choices for GraphicsOptions::fog.
• ImagePixel
  Unit-of-measure type for vectors representing the width and height of an image.
• LightingOption
  How to display light in a Space; part of a GraphicsOptions.
• Ndc
  Unit-of-measure type for points/vectors in “normalized device coordinates” (where screen-space x and y have the range -1 to 1, zero is the center of the screen, and z is image depth rather than an equivalent third spatial axis).
• NominalPixel
  Unit-of-measure type for vectors representing the on-screen dimensions of a Viewport, which may be different from the “physical” pixels of the image rendered to it.
• RenderError
  An error indicating that a HeadlessRenderer failed to operate.
• RenderMethod
  Choices for GraphicsOptions::render_method.
• ToneMappingOperator
  Choices for GraphicsOptions::tone_mapping.
• TransparencyOption
  How to render transparent objects; part of a GraphicsOptions.

Traits

• HeadlessRenderer
  Rendering a previously-specified scene to an in-memory image.

Functions

• eye_for_look_at
  Calculate an “eye position” (camera position) to view the entire given bounds.

Type Aliases

• ImageSize
  Width and height of an image, framebuffer, or window, as measured in actual distinct image pixels.
• NdcPoint2
  Screen-space point in normalized device coordinates, with depth.
• NdcPoint3
  Screen-space point in normalized device coordinates, with depth.
• ViewTransform
  Representation of a camera viewpoint and orientation.
