Leopard Only

This plugin is leopard-only at the moment, and uses some added parts from 10.5 that aren't available in 10.4 (hence the error message). Would you like a Tiger-compatible build?

Hi, do you know of anyway to reduce the 'blockyness' or pixellation that results in the most warped areas of the image using this plugin?

It's almost like the plugin needs to be sent a higher resolution to process than the one that is set automatically when scaling the viewer. If you know what I mean..

Cheers

screenshots and compositions?

Can you provide a sample screenshot and composition (with corresponding warp mesh data)? It should use bilinear filtering across the mesh, which shouldn't pixelate (it should blur, if anything)...

One cube, in a 'render in image' going to both PBmesh and a billboard.

Re: Release: PBMesh, v0.1

This might be a bug. or maybe a feature. I was making meshes for a project and realized that the y and v coords of the pbmesh input text are inverted. My mesh worked fine with warp player by paul bourke. Is there some reason they are flipped.

It was a simple fix
i just had to change my code:
out_string += x + " " + y + " " + u + " " + v + " " + i + "\n";
to:
out_string += x + " " + -1 * y + " " + u + " " + (1-v).toString() + " " + i + "\n";

thanx. this is still an awsome patch.

PS. Do you think you will ever release the source code?
