Questions tagged [rasterizing]

Rasterization (or rasterization) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (pixels or dots) for output on a video display or printer, or for storage in a bitmap file format.

In normal usage, the term refers to the popular rendering algorithm for displaying three-dimensional shapes on a computer. Rasterization is currently the most popular technique for producing real-time 3D computer graphics. Real-time applications need to respond immediately to user input, and generally need to produce frame rates of at least 30 frames per second to achieve smooth animation.

Why is my Bresenhams line algorithm crashing my program?

I have been trying to create a Bresenhams line algorithm that preserves order so that the user is able to draw on a grid at runtime. It works 'for the most part, however, it seems to get stuck in a while loop and crashes my program occasionally. I…

OpenGL scanline algorithm - does it use rays and bounding boxes?

I'm studying how scanline algorithms work and I'm wondering whether to determine the closest hit per each pixel a ray is shooted like ray tracing algorithms and, in that case, if bounding boxes are used to determine if there's an intersection or not
