Today together with @TheoA and @mostapha , I am very pleased to reveal another brother of Aragog Spider viewer – RAD viewer - new brother of Ladybug Tools – Spider. As always, it is free and open source, 3D and viewable in your browser. Finally your .RAD file can viewed on any device. This script was first shown by Mostapha at The 17th International Radiance Workshop 2018
As always, excellent work and can’t thank you enough for it! I was so tired of viewing the RAD files in ecotect (the HB RadViewers were always too slow for large models due to grasshopper limitations)
that´s cool,
when I used firefox it crashed, but with chrome it worked out after 1-2 minutes, but it was really really slow.
But as I understand it should always come down to the specs of the computer, (GPU or CPU ?) and not to browser difference
Thank you for sharing ( privately ) the file in question. It is precisely the type of file I was looking for: many triangles and a reasonable number of materials.
I should now be able to assemble the triangles into groups of meshes. This will enable the merging of vertices and more.
Fingers crossed we get a small faster model. I will try to build some of this into the next release of the Viewer. Again, thanks for sharing.
thank you to doing it.
I´m quite sure everyone who works in our field has tons of such models, and until now, the good old ECOTECT was the only program able to visualize it, but just in wireframe, so I hope you will succeed.
Fingers crossed, and if you have any question let me know.
This is the first pass at an experimental script designed to open large files.
It opens a 72 MB file in four seconds or so, but still has issues:
Only a singe color is displayed for all surfaces
Some quadrilaterals are not triangulated properly
In this version you can load multiple files one at a time using the file dialog box. I’m not sure if this is a bug or a feature. Click the script title to reload a fresh page.
Loads in like 0.0001 millisecond, and frame rate stay high, in other words, .works as a charm. The colours or some info at hover over would be appreciated
There are still many issues with triangles appearing and disappearing incorrectly. Only polygons with three or four vertices are drawn. No Spheres, cylinders and no 10 vertex surfaces with ‘openings’.
Also if the details of a material are not specified then a random color will be displayed. This happens in the private file you sent me for example.
You will note that your Warwick file displays very quickly in the RAD Viewer - quicker than the gbX/ml Viewer. It should, however, be possible to bring similar speeds yo the Viewer in future releases.
BTW, feature requests are good and bug are not needed. As you will see there are many issues - but in fixing them I may also be able to add any tricks you might crave.
Hi @TheoA, would it be possible to show the camera position and view direction somewhere on the screen? This would be useful as it would allow the use of those values to create renderings for point-in-time and annual simulations. The full list of view parameters that can be specified within radiance can be found here:http://radsite.lbl.gov/radiance/rpict.1.html (all the ones that begin with -v , for example -vp view point and -vd view direction are the ones that I am asking about).
Radiance allows a lot of flexibility in how the final renderings can be generated, however, one needs to be sure that the view settings have been set correctly before proceeding with the actual task of raytracing (which can take a few minutes to a few days). Right now one has to start a 3D software like Rhino, Sketchup etc to get the view info. Objview, the native Radiance viewer requires some getting used to and is controlled through command line options only.
Thanks,
Sarith
(PS: If you think this is something that can be done and need more detailed explanations, please feel free to ask)
