Hi All, With the next WIP release, there will be a completely new display architecture in use, as well as a new OpenGL engine. This change involved upgrading our display code to always use modern OpenGL routines when available, and required a complete rewrite of most of the core shaders/code used …

Hi Jeff, Thanks for the heads up looking forward to your* wizardry. *)you and the team -Willem

@jeff , @stevebaer , this is quite impressive. I got a mesh (4450289 vertices, 8900268 faces), comparison in shaded display mode with mesh wireframe visible, TestMaxSpeed result using Radeon HD7970 with 3GB display RAM: Rhino 5: Time to regen viewport 100 times = 41.84 seconds Rhino 6: Time to regen…

Are you bummed because it took 3.43 seconds instead of 3.26? :slight_smile:

LOL, no because i can actually use flat shade for the first time. And of course because of the speed i get now with meshes + wireframe. Usually i got good speed in shaded mode in Rhino 5 but as soon as the wireframe was overlayed, it dropped noticably. Comparison, mesh in shaded mode, without wiref…

@stevebaer , large scene nurbs test, using file with 680MB, content: 53306 block instances, 5912 curves, 5632 polysurfaces, 17114 surfaces Testing Wireframe display, with curves, no shading: Rhino 5: Time to regen viewport 100 times = 229.60 seconds. Rhino 6: Time to regen viewport 100 times = 265…

Please remember that this WIP is more about making sure things look correct after a large change in technology and are not about performance improvements. Jeff pointed out that we will be making performance improvements once we know things are displaying the correct way on user’s computers.

Yes :wink: The Rendered display shadows are btw. no comparison to V5, it really is smooth and seems to tax my GPU a lot judging from the fan which spins up immediately once entered. Looking forward to performance improvements and appreciate that i finally can use flatshade. c.

Since I don’t see a real progress in the performance test results I will wait for the official display testing start. :wink: It’s nice if the mesh results are better than before, but my biggest problem is the shaded NURBS display. I hope that I don’t need to convert my scenes to meshes anymore in t…

@stevebaer , btw. the difference in above performance test may also come from the fact that in V5 i do not have AA enabled while in V6 this is required to get smooth looking curves. In V5 i get this without AA: [image] While it looks like this in V6: [image] With AA (x8) in V5: [image] Wit…
