The most common universal file extension is shared immensely for viewing 3d presentations of product design, architecture, mechanics and props of vfx industry. But lets see how you can give more life and boost your 3d pdf presentation
The real-time render of 3d Pdf can give meaningful but bland object presentation. The lack of shading in displaying textures on any 3d object gives very undistinctive surfaces. The most common solution in these cases is to bake some lighting and shading effects into the texture themselves. We use that to implement the effect of light-trace rendering to view it in a simple 3d Pdf viewer.
You need a powerful render engine and a 3d pdf exporter. You can try out SimLab Composer from here. This software can bake your model textures with shade and shadow and light effects very easily with a powerful render engine, then directly export your 3d model with baked textures into a Pdf file.
