by Minkyung Choi With Maya deformers, you can quickly build and animate deformed surfaces with a high level of control. Switch to the Modeling or the. Sep 28, Join George Maestri for an in-depth discussion in this video Understanding wrap deformers in Maya, part of Maya: Tips, Tricks & Techniques. Feb 11, Maya also brought us the GPU Override mode, which transformed how some of Maya’s built in deformers performed. But what about all.

Finally, it enqueues the OpenCL kernel that will compute the deformation. First select the plane object that will be deformed and then the sphere object around which the wrapper is shrunk.
Select the mesh you would like to deform. The deformation occurs according to the relative distance between the two wires. In the product release demos, a rig went from 6 fps to 60 fps with the click of a button.
You may want to move, rotate or scale both elements together. Every shrinkwrap deformation contains the the wrapper the object that is deformed and the target the object around which the wrapper is shrunk. Tension T he Tension deformer simulates surface tension without squashing and stretching the surface too much.

Switch to the Modeling or the Animation Module for these examples. Use the Rigging Module.
Here There Be (GPU) Deformers
In all the examples I could find, including the official Autodesk examples, this was done with a member function of MPxGPUDeformer that looked deformwrs this:. Another problem I ran into was project structure. Squash – stretches and squashes an object. In OpenCL, you have to do this long hand.
It is not too difficult to do vector matrix multiplication. Flare – flares and tapers an object.
Wrap Use a low resolution object to manipulate a higher resolution object. You can transpose them before you write them to the GPU buffer, or transpose them in the kernel.

Any modifications you make to the curve will affect the deformera object. Your deformer data will need to be reduced down to primitive data types in order to be passed to the GPU. An MMatrix reduces to a float array. You can scale, rotate or move the points in order to deform the object into various shapes.

Select the CVs or vertices you would like to group together. Play it, stop and duplicate shapes you would like to blend between. Create a cylinder with enough divisions to bend along the length. A blend shape node is created and the target slider is an attribute of that node Prepare nCloth Shapes for Unity and Blend Make your nCloth simulation. It also is a solid example of how to approach a deformer algorithm, and organize your data.
You will need to be comfortable with the idea of flat arrays where each contiguous N elements represent a linear algebra type. In reality… it took considerably more effort. I tried to keep my GPU deformer in a separate file from my normal deformer. As the distance between the two curves decreases, so does the intensity of the Wire deformation.
Texture Texture deformers let you deform objects with a texture pattern. Wave – creates circular ripples on an object. Lattice This allows you control the deformation of complicated objects with fewer control points than deforming object directly. These may also be manipulated for various effects. Change the second sphere shape by sculpting points Change the name of the second sphere to something that describes the motion, ie.
It is specifically designed to perform morphing tasks, and it has a separate slider editor. You can also skin the lattice to an IK skeleton. You are commenting using your Facebook account. Use a curve warp when you want to deform a polygon mesh along the length of a curve.
Twist – twists an object. Judging by some of the examples in the wild, it seems that some of the behaviors surrounding a GPU deformer changed between Maya and Maya Maya will not run a deformer on the GPU if it will have to copy the data back to the CPU for a downstream node, so any deformers upstream of an unsupported node are stuck running on the CPU.
It uses the connectivity between the mesh vertices to preserve the relative lengths between them.
