* Split and rewrite the preview window and canvas. * Create a new class for handling the board information. * Adds new render targets: openGL, legacy, and ray tracing. * Render targets take full advantage of the new 3D plugins system and 3D cache for a fast 3D model loading. * Faster board loading. * New OpenGL render is faster than the old one. * New ray tracing render target with a post processing shader. * Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching. * Preview of 3D model while browsing the file name. * 3D preview of the footprint while adding / align 3D shapes. * Render of 3D models according to attributes: Normal, Normal+Insert, Virtual. * Pivot rotation centered in one point over the PCB board. * Shortcuts keys improved for XYZ orientation.. * Animated camera.
