Hi Emma, which version of Rvcg did you use? could you send me the file for debugging? I have tested the function with a variety of textured files without issues (at least no R crashes). in case your file is not a png and/or split into multiple images, you should get a message stating:
please convert texture images to png format only single texture files supported, only first one stored and if that is the case, when rendering with rgl you will get a warning: Warning message: In rgl.material(...) : RGL: Pixmap load: unable to open file 'Desktop/smilla1_0.png' for reading Best Stefan On 16/12/14 05:02, Emma Sherratt wrote: > Dear David and Stefan, > > The issue was that the PLY file of David has textures, which our > read.ply function currently does not support.
