At IFCC some of the worlds leading concept and cg artists gather to share and give live demos from the beautiful city of Split, Croatia. In this journey, a wizards leads the way by honoring worlds major artistic pillars such as art, music, agriculture and travel, all examples of ideas that creators followed through with their thoughts and contributed to the world in a positive way. A main title built entirely in Houdini. Directed from a technical standpoint with crafted design and artistic excellence.
Learning and mastering the technical tools allows one to direct and push the boundaries of creativity exponentially. This is the reason why IFCC Main Title was built entirely in Houdini and directed by a technician, Alejandro Robledo M. The aim was to think technicaly and solver creative solutions from a programming perspective. There is a special power that comes to life when one is able to direct and create both simulatiously and the better craftsmenship in the creation, the more polished the final result.
This brings us back to the rennasance days, when Leonardo crafter his painting and then executed them. But it is only through the power of his skill and mastery of the pen that he was able to render such outstanding masterpieces. Apply this craftsmenship and dedication to modern day technical engineering and mix that with the initial creative thought and one can achieve beautiful things.
For sand, PBD's was the main advantage when solving this creative problem. The main advantages of Position Based Dynamics (PBD) are its simplicity and controllability: unlike sophisticated solvers such as FLIP and FEM, PBD uses only positional constraints to determine the movement of the points in the system. It resolves penetrations by projecting points to valid locations.
This completely avoids the overshooting problems common in force based solvers. It handles collision constraints easily, and is useful for simulating sand and snow. Please find a link to SideFX documentation below.
For Cloth solutions, Alejandro focused on utilizing the power of Vellum Solver. The Vellum solver was used in its Cloth configuration and used for the characters cloth and the ships sails. Utilizing creative ways to overlap multiple layers of cloth, the wizard was able to inherit unique artistic qualities both in his fashion and gravitational effects.
Theres two very interesting tutorials that focus on breaking down how to apply cloth to a moving character and how to utilize cloth in creative ways with this solver. Please find the links below:
