Pencil sharpener

Prior to the initial Rhino 7 release I created this model of the pencil sharpener that we have lying around. It was a quick modelling practice where I stress tested Ratraced mode while modelling.

It took roughly 45 minutes to create the model with all the detailing and set up the materials. There is actually not enough back light to see the shavings I created inside as well.

The desk and lamp were created by @marika_almgren, the plant and jar I had in an old model stash, ot sure where that came from.

I added a couple of simple pencils. The pencil holder is a simple tube with a PBR material on that makes it look like I worked really hard on it. The piece of paper has a SSS material on it. The placemat is a simple cube with a leather from the Rhino material library.

I used this also to test the multi-GPU fix I made this week (will be available in Rhino 7.7). Appears to be holding up well.


lighting set up? all environment or are there lights in the scene? Gorgeous work as always!

Beautiful Lighting and Shading

Primarily the skylight through the window.

There is an emmisive material on the Led filament of the table lamp, but that is almost imperceptible. You can see it in the reflection on the lamp foot and on the glass vase.


That’s pretty sweet. Makes me wonder why I just ponied up for Maverick… :roll_eyes:

I can never seem to get my shadows that nice and soft. Do you have a sample scene you could share? I’d love to poke around and see how you’ve set things up.

I’ll see about cleaning up the 3dm file - or just set up a simpler one for sharing. After my latest fix for HDRi skylighting the environment used in this scene will actually cause sharp shadows, since there is a very high-energy spot.

But I can show how to create such soft shadows. Until I get to record something you can use one of the following tricks:

  1. Use an environment texture that doesn’t have high-energy spots (use for instance a clamped version of a HDRi such that you get pixels with highest values of ˋ1.0, 1.0, 1.0ˋ). This will generally give very soft shadows.
  2. Use a large-area rectangular light. The larger the light the softer the shadows.
  3. With directional, spot and point light set shadow intensity to something low, but larger than 0.0.

In all cases I like to not use the shadows-only ground plane (or ground plane at all for that matter).

Nice work
Quixel bridge offer a huge library of realistic textures, materials, 3d models …
You can try to use them and maybe add a feature to import them directly with conversion

For this I used only two image textures that don’t come from the Rhino material library. I try to get the best results I can with whatever Rhino itself provides. In most of my work the exception is the usage of HDRi textures. Those I get from HDRIs • Poly Haven ( former HDRI Haven).

But no doubt using third party content could help bring it even further.
