Bloom

3min
In computer graphics, bloom is a post-processing effect that is used to create the illusion of bright light sources spreading out and glowing. This is done by blurring the image and then adding a bright glow around the edges of bright objects.
Bloom is often used to create a more realistic and atmospheric look in games and other computer graphics. It can be used to make light sources appear more intense and to add depth and realism to scenes.
Here is an example of how bloom is used in computer graphics:
// Create a new 3D object
var object = new Object3D();

// Add a mesh to the object
var mesh = new Mesh();
mesh.addFace(new Triangle(0, 1, 2));

// Create a bloom effect
var bloom = new Bloom();

// Set the strength of the bloom effect
bloom.strength = 0.3;

// Apply the bloom effect to the object
object.addPostProcessingEffect(bloom);
In this example, we create a new 3D object and then add a mesh to the object. We then create a bloom effect and set the strength of the bloom effect to 0.3. Finally, we add the bloom effect to the object.
Here are some tips for using bloom:
Only use bloom for scenes with bright light sources: Bloom can be used to make light sources appear more intense, but it can also make scenes look unrealistic if there are no bright light sources.
Use bloom in moderation: If you use too much bloom, it can make scenes look over-saturated and unrealistic.
Experiment with different bloom settings: The strength of the bloom effect can be adjusted to create different looks.
By following these tips, you can use bloom to create visually appealing and realistic computer graphics.
