The document discusses various aspects of visual rendering, including the use of sprite visuals, brushes, and effects in UWP applications, emphasizing the importance of using Win2D for graphics. It describes different types of lights—point lights, directional lights, and spotlights—and their characteristics in a scene. Additionally, it mentions the use of height maps to create texture illusions and provides resources for further learning.

- 4. • Visual Tree – • SpriteVisual - The visual that is used to draw content on screen • Brushes - CompositionEffectBrush paints a visual with the contents of a composition effect • UWP - Where possible use Win2D (OSS graphics C# runtime) packages for effect descriptions
- 5. Create a SurfaceBrush to hold your source content Describe your effect Compile your effect Apply your effect
- 6. At the description step – Add another effect as source input to the effect
- 7. At the compile step - specify animatable properties new[] { "SaturationEffect.Saturation" }); myEffect.Properties.InsertScalar("saturationEffect.Saturation", 0f); Create your animation Start the animation on the saturation property
- 10. Point lights have color and position within a scene, but no single direction. They give off light equally in all directions. Like a lightbulb lights have only color and direction, not position. They emit parallel light. This means that all light generated by directional lights travels through a scene in the same direction. Like the sun Spotlights have color, position, and direction in which they emit light. Light emitted from a spotlight is made up of a bright inner cone and a larger outer cone. Like a flashlight.
- 11. Diffused light appears to be a non-reflective surface and the light is scattered in all directions Specular lighting effect appears to be a reflective surface Height maps create an image with surface and elevation information to create an illusion of light falling on the textures of an image.
