Just press »F« on your keyboard to show your presentation in fullscreen mode. Press the »ESC« key to exit fullscreen mode.
Press "Esc" or "o" keys to toggle the overview mode on and off. While you're in this mode, you can still navigate between slides, as if you were at 1,000 feet above your presentation.

Pixels Per Inch (PPI) – количество пикселей на дюйм экрана.
DPI (Dots Per Inch) – используется для печати, но иногда применяется и к экранам.
Resolution – общее количество пикселей по ширине и высоте (например, 1920×1080).
Polygons are the fundamental building blocks of 3D computer graphics, representing surfaces using vertices, edges, and faces.
Polygon Mesh (Wikipedia)
Polygons are measured in terms of vertex count, triangle count, and mesh density.
Level of Detail (LOD) controls how many polygons are displayed depending on distance.
Pixel coverage: A single polygon can span multiple pixels depending on camera projection and resolution.
ASCII art uses characters to create images and is often seen in retro computer graphics and early digital art.
ASCII Art (Wikipedia)
Measured in terms of character grid:
- Screen resolution in characters (e.g., 80×25, 132×43).
- Font size determines how many characters fit on the screen.
- Character aspect ratio affects image proportions.
Voxels are volumetric pixels used in 3D graphics, similar to pixels but in a three-dimensional space.
Voxel (Wikipedia)
Measured in voxel grid resolution:
- Voxel Size: Defined in world space (e.g., 1mm³ per voxel).
- Voxel Density: Number of voxels per unit of space (e.g., 256×256×256).
- Screen Projection: A voxel may occupy multiple screen pixels based on viewing angle and resolution.
E-ink technology mimics the appearance of ink on paper and is commonly used in e-readers.
Electronic Paper (Wikipedia)
- E-ink screens use pixel-based measurements similar to LCDs.
- Resolution is measured in pixels (e.g., 1448×1072).
- PPI is typically high (e.g., 300 PPI for Kindle Paperwhite).
The Ferrolic display uses ferrofluid, controlled by magnets, to create dynamic visuals.
Ferrolic Screen (YouTube)Raster images are made up of a grid of pixels, with each pixel having a specific color and intensity. They are typically used for photos and complex images.
Common Formats: JPEG, PNG, GIF, BMP, TIFF.
Vector images are created using mathematical equations to define geometric shapes. They are resolution-independent and can be scaled infinitely without losing quality.
Common Formats: SVG, EPS, TTF, PDF, AI (Adobe Illustrator).

Fractals are complex, self-replicating structures that can be generated using mathematical formulas. They are often used to create intricate patterns and textures in CG.
Common Formats: PNG, JPEG (after rendering), fractal-specific files like .fsc (for some fractal software).
