Volumetric path tracing

Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. 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, explosions, smoke, clouds, fog or soft shadows. Like in the path tracing method, a ray gets followed backwards, beginning from the eye, until reaching the light source. In volumetric path tracing, scattering events can occur along with ray tracing. When a light ray hits a surface, a certain amount gets scattered into the media. (Wikipedia).

Volume Flow Rate & Mass Flow Rate - Fluid Dynamics Physics Problems

This physics video tutorial provides a basic introduction into mass flow rate and volume flow rate. The mass flow rate is the change in mass per unit time. It is also equal to the product of the fluid density, cross sectional area and the speed of the fluid in a pipe. The volume flow ra
