The art club venue was not available today, so we all went to a church instead. I usually paint watercolour, but I did some drawing today for a change.

Last week's art club painting. Brief was "music".

Looking at my solar panel data output is fascinating. The 16C swing from Tuesday night's temperature to last night is obvious in the frequency that my central heating turned on (orange downward spikes. Left is Tuesday night, right is Wednesday night. Key for the other colours is in the second image.

Just read the info about #half-edge. Looks really cool! I was thinking about doing something similar after really struggling to get to grips with Blender, for the same reasons you state. Very interested in the .OBJ output, as I just happen to have a ray-tracing renderer I wrote that will read them 😊

Looks ... interesting. The images are too complex for me to figure out what's going on. Could you elaborate?
I once built a "functional" Newtonian telescope in my renderer and was able to see the image of a distant flower on the focal plane. See ALT text for descriptions.

3D vector algebra is fun, and Bezier splines are awesome!
Here's an extruded objected created by sweeping an outline along a path in 3D space defined by just 8 points.
Modelled in ODL (my own language)
Rendered with my own toy ray-tracing renderer.

That's an awesome picture!
I hope you don't mind, but I took the liberty of combining your picture with one I took of the Milk Way from the northern hemisphere last week. I never see what you see!

Another exceptionally clear night tonight. Here's a picture of the Milky Way in the constellation Cygnus, and with the constellations annotated.

It was really clear tonight, so I snapped a quick picture of the Milky Way as it runs through the constellation Cygnus.

Still a little buggy, but *much* better now.
Just needed to update the materials ID list buffer 🙄

I've seen some strange bugs in my time .. but this one in my own hobby renderer has me scratching my head in disbelief.
The materials associated with the objects (the three little balls) change with position. There must be some pointer corruption going on .. but it's otherwise so stable! No crashes!

I've just done a couple of quick renders of this *GORGEOUS* model of the Apollo 11 Command Module from the #Smithsonian museum using my own ray-tracing renderer.

I just used Cursor to generate the Object Description Language file that describes this scene to my hobby renderer.
It's simple at the moment, but I have plans ... 😉

@leerob.com I just taught Cursor the syntax of my proprietary Object Description Language for my ray tracing renderer, and with a bit of back-and-forth, it generated the ODL file that describes this rendered scene.
It's very simple, but I have plans ..... 😉

Went to mow the lawn and a plastic part on the mower had broken so had to make a new one. Why is nothing ever simple...
