Rastrer

Rastrer is a type of rasterization technique used in the field of computer graphics and design. Rasterizing refers to the process of converting 2D vector graphics into a rasterized image, which can be composed of pixels on a display screen.

This technique involves mathematically determining the intersection of a curved vector line with a network of closely spaced horizontal and vertical grid lines. Each intersection point on the grid defines a pixel that will be generated in the final rasterized image. This means that the accuracy of the rasterization process is highly dependent on the density of the grid used.

The impact of grid density on the staircase effect should not be overlooked. This effect occurs when there are noticeable and unnatural-looking stair-step patterns in the final rasterized image due to inadequate grid density. Trades are often made in the field between increasing the complexity of the grid (which offers more accuracy) and increasing the processing time required by said density.

Rastrer is distinct from other rasterization techniques, such as Bresenham's line algorithm. Bresenham's algorithm uses a specific set of rules for line segment rasterization with integers results not requiring explicit fleshed-out space.
