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.

The deformation occurs according to the relative distance between the two wires. First select the plane object that will be deformed and then the sphere object around which the wrapper is shrunk.

In all the mayya I could find, including the official Autodesk examples, this was done with a member function of MPxGPUDeformer that looked like this:. Do this before animating if you are making a blend shape for Unity. Notify me of new comments via email. You are commenting using your WordPress.

You will need to be comfortable with the idea of flat arrays where each contiguous N elements represent a linear algebra type. Maya creates Lattices around the object and when you transform the influence lattice, the object inside it gets deformed.

Here There Be (GPU) Deformers – Yantor3d

Wave – creates circular ripples on an object. You can also skin the lattice to an IK skeleton. Wrap Use a low resolution object to manipulate a higher resolution object.

Fill in your details below or click an icon to log in: Finally, Maya deformers may involve matrix multiplication. Change the second sphere shape by sculpting points Change the name of the second sphere to something that describes the motion, ie.

I tried to keep my GPU deformer in a separate file from my normal deformer. Select the mesh you would like to deform. You can also access blend shape sliders in the Attribute Editor or through the channels in the Channel box.

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.

If you need more information about the functions available to use in your OpenCL, Google is your friend. Delta Mush works with skinned IK joints. In this type of animation, a group set shapes such as certain phonemes or facial expressions need to be readily accessible, editable and blendable. To find out more, including how to control cookies, see here: Lattice This allows you control the deformation of complicated objects with fewer control points than deforming object directly.


Email required Address never made public. You are commenting using your Facebook account. Select the mesh you would like to deform, and use shift to select the curve. You may want to move, rotate or scale both elements together. You can transpose them before you write them to the GPU buffer, or transpose them in the kernel. You can scale, rotate or move the points in order to deform the object into various shapes.

Here There Be (GPU) Deformers

Every shrinkwrap deformation contains the the wrapper the object that is deformed and the target the object around which the wrapper is shrunk. An MMatrix reduces to a float[16] array. In the product release demos, a rig went from 6 fps drformers 60 fps with the click of a button.

Use a curve warp when you want to deform a polygon mesh along the length of a curve. Jiggle Think jello, this is not so effective, because it is difficult to control.

Squash – stretches and squashes an object.
