![]() ![]() LOVE binary STL model by Drayde, from thingiverse, ![]() The SpotLight is very visible, but the Graphics Processor is doing lots of work.Īn interesting side-effect of "Best" is that the black square could be made of 2 triangles, 4 vertices which would greatly reduce the model size in GPU memory, and the visual result would be the same when in "Best" mode. Lighting done on a per-Fragment basis, so at each fragment of a triangle, lighting calculations are performed. You can almost see the triangles indeed, if the triangles were larger, the SpotLight effect can actually disappear, if no Vertices are "hit" by the light. Square made of many triangles lighting when in "Fast" mode is done by interpolating light from Vertex to Vertex - this is the traditional OpenGL way of interpolating light across a triangles' surface. Yellow SpotLight shining on black square. The top vertical edge, which is shared with the other faces of the box, is identified as having a Manifold issue, and the other two edges are flagged with having an edge issue.Ĭlick on the picture for a full-size screen shot from a Google Nexus-7. The duplication has one vertex pulled out, creating a flap. The box has been filled, and the inside material has been changed to a dark blue, to help outline the missing facet.īox, with one facet duplicated. The algorithms in FreeX3D find this missing facet, outline it in red, and place a count of edge issues in the Info screen. Here are two examples of a simple box, one with a hole in it, the other with an extra triangle.īox-hole.stl and box-manifold.stl are shown below these models also have facet normal errors, so if run in "Original" mode, (or in other STL viewers) the box may appear unlit.īox with a missing facet. FreeX3D can, if the "Check" option is selected (see the STL page). The pictures are clickable, and the models are available by downloading the relevant links.ģD printers require models that are printable.

Work continues on the FreeWRL library code base, cross platform compatibility, and on the pre-compiled "FreeX3D" Android App. Ubuntu build and install revisited working on getting some issues fixed for a V2.0 release. Stereovision updown viewports added for interlace shutterglasses, in addition to the existing sidebyside, quadbuffer and anaglyph. Navigation, protos, sound, inline import/export, javascript interface improved.ĭuktape javascript engine option added for platforms with no spidermonkey. Version 3.0 released, SSR (server-side rendering) toy in vista-10 version, target frame rate limit adjustment, pinnable menubar, unpinnable statusbar, choice of menubar colorschemes. Version 3.1 released, with changes for statusbar and menubar: commandline option -want FF to suppress statusbar and menubar touch-toggling of unpinned statusbar and/or menubar improved ? help. Please download the source code from the git repository,Īnd get the "origin/develop" branch (see the "Download" page Plus 2 non-spec nodes: Teapot (geometry node) and (compositing shader) Effect (child node).ĭevelopment continues, but we have not make a binary release in a while. Version 4.0 (codename: Kelp Forest) release: 101 more node types added: see Conformance page for current state of specs nodes.
