I'm working on a little experimental texture painting program. http://www.youtube.com/watch?v=haMfp641sHM Horde works surprisingly well for this purpose, with one exception: I'm using a rendertarget to store each texture point's 3D position (similar to deferred lighting). This, unlike projection, allows for pixel-perfect seamless painting but this only works when the buffer is exact same size as the texture. And that's my problem, I can't set buffer size inside the application, so i have to edit pipeline.xml to match size of the edited texture. Is there some way to change buffer dimensions from inside the application? ResizePipelineBuffers changes all at once, including those i don't want resized. |

One way would be to change the pipeline xml width to a dynamically created one with the new width and height settings and reload the pipeline resource. A more efficient one, may be the following (UNTESTED) patch.

Wow, that was fast! Works perfectly after small change ( replaced ResHandle with H3DRes in DLL void h3dResizePipelineBuffer( ResHandle pipeRes, int index, int width, int height ); otherwise it refused to compile) Thanks for the help. |
