Melody FAQ

What is Melody?

See the description of Melody on the Melody homepage.

Does Melody work on GPUs from other vendors?

Melody should work with any GPU that supports PS2.0 shaders.  Additional minimum system specification (minspec) requirements are:

• Windows XP or 2000
• DirectX 9

What geometry file formats does Melody support?

Melody supports reading .3ds, .obj and .ply file formats.   The .3ds file format has a 64K poly limit per mesh, but you can have multiple meshes in each .3ds file. If your geometry is not in a format supported by Melody, you will need to convert it to a format that is supported.

What is the maximum number of polygons Melody can support?

The maximum number of polygons Melody can support is limited by the amount of main memory available on your system.  PCs can address as much as 4GB of memory, and that can contain huge models.  The display driver also needs to have enough memory to create a vertex list for your model, so it can be displayed.

How much does Melody cost?

NVIDIA does not charge for Melody.  It is provided for free as part of our developer tools program.  Please let us know if you would like help incorporating similar features in your commercial products.

Is source code available for Melody?

Full source for Melody is not available; however, a portion of Melody is based on the MixKit open source library for multiresolution surface modeling.  Source code for this component of Melody is available on request by sending e-mail to SDKFeedback@nvidia.com. Additional information about the latest version of MixKit is available from http://graphics.cs.uiuc.edu/~garland/software.html.
