mfdesigner Posted May 18, 2016 Share Posted May 18, 2016 This nuclear explosion effect is built using our real-time fluid simulation engine in combination with the following techniques: (1) Perlin noise turbulence (2) Sample jittering (3) Anisotropic scattering (4) Multiple forward light scattering (5) Full implementation of Blinn-Phong optical model (6) Dynamically injecting density, temperature, divergence to create expansion upon fuel ignition and later contraction. To see it in action, view this project in PetriDish - our free online editor. Quote Link to comment Share on other sites More sharing options...
mfdesigner Posted May 19, 2016 Author Share Posted May 19, 2016 After extended tuning of temperature color palette and other light scattering parameters, i was able to produce much better result. The detail of the blast cloud is now much more pronounced. This simulation was performed on a 93 x 143 x 37 grids. Thanks to vorticity confinement and sample jittering, I was able to artificially create more details from limited number of grids. Quote Link to comment Share on other sites More sharing options...
mfdesigner Posted May 29, 2016 Author Share Posted May 29, 2016 Physically based Tornado animation using our real-time fluid simulation engine... closely following this thesis by DWIVEDI. The funnel shape is art-directable and follows the spline path drawn by a user. Pryme8 1 Quote Link to comment Share on other sites More sharing options...
