Computer Graphics Questions
Alpha blending is a technique used in computer graphics to combine two or more images or objects with transparency. It involves blending the colors of the foreground object with the colors of the background object based on the alpha value of each pixel. The alpha value represents the level of transparency or opacity of a pixel, ranging from 0 (completely transparent) to 1 (completely opaque).
During alpha blending, the color of the foreground object is multiplied by its alpha value, while the color of the background object is multiplied by (1 - alpha value). These two resulting colors are then added together to produce the final blended color. This process allows for smooth and seamless integration of objects or images with varying levels of transparency, creating realistic and visually appealing graphics.
