Study Notes
Texture Maps
- A 2D texture map is a 2D image or pattern that is applied to a 3D object to give it visual detail and texture.
3D Paint Tools
- A 3D paint tool in computer graphics is used to add color, texture, and other visual effects to 3D models and objects.
3D Unit Vectors
- A 3D unit vector is a vector with a length of 1 that is used to represent direction and orientation in 3D space.
2.5D Rendering
- 2.5D rendering is a technique used to create a 3D-like effect by adding depth and visual interest to a 2D image or scene.
4D Vectors
- In graphics code, a 4D vector commonly holds homogeneous coordinates (x, y, z, w) that represent a 3D point or vector in a 4D space.
