mmm in #blender I tested Cycles but apparently only #luxcore is able to correctly simulate a light source bouncing on a mirror ... I'm looking at some simulation for a project that use hemispheric mirror for dome like projection ...
the pattern seen here in the white is due to the hemisphere being made of faces, I had to make it super detailed, each "dot" is one facet reflection (the light source is invisible)
just a reminder that #b3d #blender #cnc addon BlenderCam is still developped, and that last version works on 2.90 and is pretty complete for 3 axis milling/cutting ...
wondering if you can see your model in #vr and export the gcode directly in any other 3d package out-there ;)
so it appears latest versions (2.91 alpha - this will trickle down to 2.90 and 2.83) of #blender finally works well in #vr with #openxr on #linux with #openvr backend or #monado, at least with AMD video cards (navi10 chips)
the #eevee rendering is even pretty usable if you disable some effects that need multiple redraws (like bloom or volumetric shadows)
cool ... I could manage to record a video of an interactive scene with external sensors datas (using an arduino as HID joystick input) in #godotengine in csv then load them in #blender (2.79 ... I need to update my bpy knowledge) to drive animations synched to that video to render a "meta" scene with a visualisation of the player and the screen
now I'm wondering if the sim would play the same (is it deterministic?) if I put the datas back as controls ;p (I bet not so much) #b3d
collective virtual portrait during a #pandemic ... (not the 1rst!)
this archery guild ( > 600yo!) cannot meet for months nor participate to a bigger annual walk
Now they have participated to a virtual meeting by sharing photos of them with masks we gathered in a 3D space of the historical shooting range.
I'm so happy with #mozilla #aframe #vr framework ... it works in a snap to present projects on any terminal (2d magic mirror, desktop fps or hmd)
the process to bake the lightning in #blender #b3d is still a bit touchy (from my pov regarding people with no prior 3d pipeline knowledge) but the end result in term of "convenience" for once with #floss is priceless
<3 to the devs
and hope they join the fediverse at some point ( :z they still use discord/birdsite to coordinate/communicate :/)
and now a higher backside with hollowing and more interlocking work (not very visible here)
I think I'm near the point I can make a test, it fits on the plank, I just have to push the design in inkscape to extract a gcode
so apparently concerning "viewport-texture" there is no implementation in blender 2.8x to this day ?
I'm looking for the way to have the view from one/x camera(s) available as texture for objects
in 2.5+ we could use the Game Engine Video Texture module to do crazy things including realtime #videomapping , mirrors, virtual cams, larsen effects
I don't find the way in 2.8+ although it sounds like it could be doable with viewports? (unfortunately BenoitB is not around anymore... ) #b3d
ILM is using "video projection mapping" techniques now to set the backgrounds of the scene, using realtime 3D rendering with perspective correction from the camera pov. It has many advantages over green screen.
It seems nowadays their best solution uses out-of-range LCD screens that needs 5y to grow the crytals for (!) but used laser projectors and led walls too
2 good pres. today #bconf talked about the Video Sequence Editor in #b3d #blender : specifically pointing the ability to use it to assemble and edit your entire project. By combining scenes, you can quickly jump from edit to scene, and even using that to block then replace fully done shots along the work. You can even work with linked scenes edited on a network by other people !
I worked like that last year for a music video commission : (green bar are scenes) (repost)
you ask the blender game engine to add 0.1 or subtract 0.01 from a variable initally set at 1.0 depending or whether you click on the mouse or not, and you end up with ...
ho wow ... I did not tried it before but you can actually install blender 2.79b from the #raspbian repo on the #raspi 3b / 4b and it's actually totaly usable even on the 3b, including the game engine ... (a little slow at HD res but still! )
it totaly beats #godotengine on the #raspberrypi 3b as I can even load a bunch of images that made godot freeze ... (but godot had higher fps when loading on demand...) cool for education also as you can model and render simple things too #b3d
