Luxology has announced the availability of recoil, a new plug-in for modo 501 that accurately simulates dynamic rigid body interactions. Based on the popular open source Bullet physics engine, recoil simulates dynamic forces and calculates collisions between objects, allowing users to create complex animations or stack vast numbers of objects. The plug-in was developed independently by Eric Soulvie using the modo Plug-in Software Development Kit (SDK) and runs on both the PC and Mac versions of modo 501.
Utilizing version 2.77 of the Bullet physics engine, recoil simplifies the execution of complex physical simulations by combining robust collision detection with a variety of constraints, forces and controls. By tagging any mesh item to be dynamic, the object is ready to respond to forces like gravity or collisions from other objects in a modo scene.
"The integration of the Bullet rigid body dynamics into modo went very smoothly and the resulting animations are astonishingly realistic," said Eric Soulvie, the Seattle-based developer of the recoil plug-in. "The recoil plug-in supports the option of collision detection directly with the Subdivision Surfaces, not just the cage geometry, which provides for more detailed simulation results."
The recoil plug-in is a seamless extension to modo and offers a wealth of new functionality for modo 501 users:
• Any mesh item can be made dynamic with recoil, making it subject to forces like gravity or collisions with other objects in the scene
• Objects can be given "wake-up" conditions and an initial "impulse" behavior. A common wake-up event would be a collision, perhaps with an impulse behavior to jump up slightly and then respond to the force of gravity.
• A system of connectors, including springs and motors enables complex linked behaviors like spinning gears, elastic coils or swinging chains
• Dynamic simulation can be combined with traditional keyframe animation so that a swinging bat can collide with a tower of pins that scatter and fall to the ground
• recoil is also useful for stacking objects so that they come to a resting position naturally, such as cubes of sugar in a dish or gumballs in a vending machine
"recoil is a fast, powerful and fun-to-use product that will be attractive to our large community of modo users," said Brad Peebler, president and co-founder of Luxology. "This is the most extensive use of the modo Plug-in SDK to date and represents a significant milestone for modo as a 3D platform."
The recoil plug-in is available now at US$199. Related links:Luxology modo 501
