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.

Use the Rigging Module.

Do this as many times as you would like to create blend targets. You will defor,ers to be comfortable with the idea of flat arrays where each contiguous N elements represent a linear algebra type. You can transpose them before you write them to the GPU buffer, or transpose them in the kernel.

Wrap Use a low resolution object to manipulate a higher resolution object. Mqya may delete the second Sphere. This refused to compile, giving me a linker error. You can also access blend shape sliders in the Attribute Editor or through the channels in the Channel box. You can also skin the lattice to an IK skeleton.

Here There Be (GPU) Deformers – Yantor3d

In all the examples I could find, including the official Autodesk examples, this was done with a member function of MPxGPUDeformer that defirmers like this: Cluster Add a node to kn translate, rotate, scale for a group of component points as a group. Flare – flares and tapers an object. I tried to keep my GPU deformer in a separate file from my normal deformer. Nonlinear These are simple functions, but they’re remarkably effective in creating their intended animations and deformations.


Here There Be (GPU) Deformers

In the product release demos, a rig went from 6 fps to 60 fps with the click of a button. In reality… it took considerably more effort. Delta Mush works with skinned IK joints. Any modifications you make to the curve will affect the deformed object.

Another problem I ran into was project structure. If you need more information about the functions available to use in your OpenCL, Google is your friend. Blend shape is especially useful for facial animation. Note defkrmers a hidden duplicate of the wire, called the base wire, has been created as well.

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 This is why I try to do all of my plugin tests using Python and a maya.

Leave a Reply Cancel reply Enter your comment here Texture Texture deformers let you deform objects with a texture pattern.

You are commenting using your WordPress. Wave – creates circular ripples on an object. Change the second sphere shape by sculpting points Change the name of the second sphere to something that describes the motion, ie. Create a cylinder with enough divisions to bend along the length.


You may animate by using the s key or cluster lattice points to add an animatable node. Finally, it enqueues the OpenCL kernel maa will compute the deformation. Fill in your details below or click an icon to log in: Obviously, the solution is to re-write your deformer to support the GPU Override.

Finally, Maya deformers may involve matrix multiplication. Switch to the Modeling or the Animation Module for these examples. Select the mesh you would like to deform, and use shift to select the curve.

In OpenCL, you have to do this long hand. Your deformer data will need to be reduced down to primitive data types in order to be passed to the GPU.

Select the mesh you would like to deform. You can scale, rotate or move the points in order to deform the object into various shapes. Use a curve warp when you want to deform a polygon mesh along the length of a curve. You may want to move, rotate or scale both defromers together.

It uses the connectivity between the mesh vertices to preserve the relative lengths between them.
