I have come back to Rhino to have another stab at surfacing vehicles. I gave up years ago because I was unable to accomplish this after at least 100hrs of youtube videos, trial and error and the manual (well written) Perhaps I am expecting too much from a CAD tool, but these examples I see of vehic…

@DavidRutten [Sci-Fi idea] Now I’m wondering, since the mouse is now connected directly to the GPU, bypassing the CPU; If instead of a traditional C, a shader graph is use instead to make the red Grasshopper surface mesh,… I mean using shader language to build the mesh directly. You bake the final …

Are you proposing we convert our multi-thousand line NURBS mesher, which relies on hundreds of other methods, from C++ into GLSL?

I think he is, and I think you are on the verge of rejecting it out of hand as “too much work”. I think Alan has a very interesting idea with what sounds on the surface of it as having a lot of potential. I think it would be useful if you (and the rest of the team) adjusted your attitude to “probabl…

[image] AlW: I think he is, and I think you are on the verge of rejecting it out of hand as “too much work” Oh I’ll let @stevebaer reject it out of hand for me. I don’t even know if it’s possible in a shader language to create a functionally equivalent mesher. You’d have to basically convert …

[image] DavidRutten: I really don’t want to be the one saying it can or can’t be done. OK. Understandable. It’ll be interesting to hear what Steve has to say, should he choose to respond.

The only reason to have computation code run on the GPU is to take advantage of the large number of processors available. These processors aren’t faster than the CPU, there just happen to be a lot of them. Moving code to work on a GPU isn’t the issue, it’s about rewriting code with entirely differe…

Yes! old and new running in parallel together. One (red mesh in shader language { meshlets mesh shade r??}) in real-time with low precision for visualization only, other (Grashopper → C++) for double-checking and baking To resume, I know about shaders but not how to use the tensor core side other tha…

I misunderstood what you were asking. Yes it is possible to color pixels on the screen with raw polysurface data and GPU shaders. I would say possible, but also very hard to implement (and make work on the majority of graphics cards out there). I’m sure there are a number of research projects that …

[image] stevebaer: projects that attempt to draw shaded polysurfaces entirely through GPU shaders [Procedural texturing of a parametric building for VFX, with Substance Designer & Substance Painter]

I don’t believe that video is what I was trying to explain.
