Bloom in digital cameras is caused by an overflow of charge in the photodiodes, which are the light-sensitive elements in the camera's image sensor. [3] When a photodiode is exposed to a very bright light source, the accumulated charge can spill over into adjacent pixels, creating a halo effect. This is known as "charge bleeding."
Ray tracing solves this problem by reversing the process, instead sending view rays from the observer and calculating how they interact until they reach a light source. [24] Although this way more effectively uses processing time and produces a light simulation closely imitating natural lighting, ray tracing still has high computation costs due ...
The original light tracing and backwards path tracing algorithms are both special cases of these strategies. For light tracing, it is connecting the vertices of the camera path directly to the first vertex of the light path. For backwards path tracing, it is connecting the vertices of the light path to the first vertex of the camera path. In ...
Tracing rays starting at the light source can also be called particle tracing or light tracing, which avoids this ambiguity. [34]: 92 [35]: 4.5.4 Real-time rendering, including video game graphics, typically uses rasterization, but increasingly combines it with ray tracing and path tracing.
Comparison of accurate reflections computed with path tracing (left), approximate reflections with environment mapping (middle), and screen space reflections (right) For rendering environment reflections there exist many techniques that differ in precision, computational and implementation complexity. Combination of these techniques are also ...
Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. [1] This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire ...

Specular highlights on a pair of spheres. A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image on right). ). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the
