Quick Reference

Raster vs. Vector Graphics

Raster graphics are composed of pixels arranged in a grid, making them resolution-dependent and prone to quality loss when scaled. Vector graphics are defined by mathematical paths, allowing infinite scalability without loss of quality.

Keyframe Animation

A technique where the animator defines the object's position, rotation, scale, or other properties at specific points in time (keyframes), and the software interpolates the values between those keyframes to create smooth motion.

Layers and Compositing

A workflow in which different elements of an artwork or animation are placed on separate transparent layers that are stacked and blended together. This allows independent editing of each element without affecting others.

3D Modeling and Mesh Topology

The process of creating three-dimensional objects using polygons (typically triangles and quads) that form a mesh. Good topology refers to clean, logical edge flow that allows for proper deformation, smooth shading, and efficient rendering.

Rigging and Skeletal Animation

Rigging is the process of creating a virtual skeleton (armature) inside a 3D model so that it can be posed and animated. Bones, joints, and constraints define how the model deforms when moved.

The 12 Principles of Animation

A set of foundational guidelines developed by Disney animators Ollie Johnston and Frank Thomas, including squash and stretch, anticipation, staging, follow-through, timing, exaggeration, and others that create the illusion of life in animated characters.

Color Theory in Digital Media

The study of how colors interact, including concepts like hue, saturation, value, complementary colors, analogous palettes, and color temperature. Digital artists work in color spaces such as RGB for screens and CMYK for print.

Rendering and Shading

Rendering is the computational process of generating a final 2D image from a 3D scene. Shading determines how surfaces respond to light, using material properties like diffuse color, specularity, roughness, and transparency.

Motion Graphics and Kinetic Typography

Motion graphics are animated visual elements, typically used in video, advertising, and user interfaces. Kinetic typography animates text to convey emotion, rhythm, or narrative emphasis.

UV Mapping and Texturing

UV mapping is the process of unwrapping a 3D model's surface onto a 2D plane so that 2D textures (images) can be applied accurately to the 3D geometry. The U and V coordinates correspond to X and Y axes on the texture.

Key Terms at a Glance

Alpha Channel:A channel in a digital image that stores transparency information for each pixel.

Ambient Occlusion:A shading technique that calculates how exposed each point on a surface is to ambient light, adding soft shadows in crevices and corners.

Armature:A virtual skeleton structure used in 3D animation to control the deformation and movement of a character model.

Bezier Curve:A smooth curve defined by control points, used in vector drawing, animation paths, and font design.

Bitmap:An image represented as a grid of pixels, where each pixel stores color and sometimes transparency values.

Blending Mode:A mathematical formula that determines how a layer's pixels combine with the pixels of underlying layers.

Compositing:Combining multiple visual elements from different sources into a single cohesive image or sequence.

DPI (Dots Per Inch):A measure of print resolution indicating how many ink dots fit in one linear inch. Higher DPI means finer detail.

Easing:Gradual acceleration or deceleration of motion in animation, controlled by interpolation curves between keyframes.

Frame Rate:The number of individual frames or images displayed per second in an animation or video.

Global Illumination:A group of rendering algorithms that simulate how light bounces between surfaces, producing realistic indirect lighting.

HDRI (High Dynamic Range Image):An image with a greater range of luminance than standard images, used in 3D rendering to provide realistic environment lighting.

Interpolation:The automatic calculation of intermediate values between two defined keyframes to create smooth transitions.

Keyframe:A frame in an animation where a specific property value is explicitly defined by the animator.

Mesh:A collection of vertices, edges, and faces that define the shape of a 3D object.
