Leveller 2.5 alpha now at build 1281. http://www.daylongraphics.com/products/leveller/download/lev25a.zip http://www.daylongraphics.com/products/leveller/plugins/download/lev25a_pi.zip - Plug-ins updated to match; the older 2.5 plug-ins may not work. If you get one package you should get the other. - Right mouse click was not aiming camera; fixed. - View, Render... command added. This brings up a dialog letting you execute Renderer plug-ins, which draw the current document using entirely their own method. The example 'Detail Increase' renderer plug-in is provided in the plug-ins archive; it synthesizes extra heightfield detail by subdividing each HF cell into four triangles. The existing scanline renderer will eventually be made into a Renderer plug-in, and the raytracer may follow. There's little limit to what a renderer plug-in can draw; Leveller sets up an OpenGL context (or one can draw with GDI) and aims the camera but that's it. The plug-in can scanline, raytrace, REYES, add a zillion objects, whatever. Ray
