> In offline rendering we usually just have some primitive (sphere, cube etc) that acts as the boundary Right, using a SDF as a boundary condition is to discretely check it as an i…

> SDF is still just a surface/boundary representation Meshes and Bezier patches are parametric representations (defined over R^2, evaluated with vec2, output vec3). Implicit functi…

This is a bit confused. Current RT implementations are faster at intersecting the mesh along the ray direction than sphere tracing (which require the expensive lookups or evaluatio…

>Why are SDFs useful at all? Meshes and bezier patches are boundary representations with no information of the volume they enclose. Imagine you'd like to cut an object out of smoke…

Memory savings are the main potential gain, since you won't need as deep a tree. This is not the main issue with this tech atm. Also, their distance output will be an estimate, it …

It's easiest for laptops, since the laptop trays have adjustable angle. If you need a desktop monitor, you can get an over-bed table and mount a small VESA mounting arm. If you can…

Why reinvent the bed? All you need for a lay down desk is a 12 inch orthopedic foam wedge and a laptop tray. Both readily available in Amazon. I've been working this way for years.…
