it seems that was this. Now all is working fine !
Glad that it worked! But I am still a bit worried. Gismo components only modify the gdal-data/osmconf.ini file and no other MapWinGIS file. So your MapWinGIS installation files should not be compromised. The fact that you did not get the "COM CLSID" error message when running the "Gismo Gismo" component suggests that MapWinGIS has been properly installed. So I wonder if the cause for the permanent "invalid shapes" warning has again something with the fact that your system is again not allowing the MapWinGIS to properly edit the osmconf.ini. Maybe this problem will appear again, and again, and reinstallation of MapWinGIS every time can be somewhat bothersome.
- About the terrain generation, is it possible to have the texture from google or other provider mapped onto the terrain surface from gismo component ? (Same as using the ladybug terrain generator in fact). I try to used the image extracted by ladybug component and then applied it to the gismo terrain but the texture is rotated by 90°.
The issue with the rotation can be solved by swapping/reversing the U,V directions of the terrain surface. A slightly more important issue is that terrain surface generated with Gismo "Terrain Generator" component might have a bit smaller radius than what the radius_ input required. This stems from the fact that the terrain data first needs to be downloaded in geographic coordinate system, and then projected. Some projecting issues may occur at the very edges of the projected terrain, so I had to slightly cut out the very edges of the terrain which results in the actual terrain diameters being slightly shorted in both directions. This means that if you apply the same satellite image from Ladybug "Terrain Generator" component to Gismo "Terrain Generator" component the results may not be the same.I attached below a python component which tries to solve this issue by extending the edges of Gismo "Terrain Generator" terrain, and then cutting them with the cuboid of the exact dimensions as the radius_ input. Have in mind that this extension of the original terrain at its edges is not a correct representation of the actual terrain in that location. But rather just an extension of the isoparameteric curve of the terrain surface. So basically: some 0 to 10% (0 to 10 percent of the width and length) of the terrain around all four edges is not the actual terrain for that location, but rather just its extension.The python component is located at the very right of the definition attached below.
Also, if you would like to use the satellite images from Ladybug "Terrain Generator" component along with "OSM shapes", sometimes you may find slight differences in position of the shapes. This is due to openstreetmap data not being based on Google Maps (that's what Ladybug "Terrain Generator" component is using), but rather on Bing, MapQuest and a few others.
- About the requiredKeys_ input of OSM shapes, I understand what you mean and your advice, but in most cases I use it, the component was working fine even without input. I think it's better to extract all tags, values and keys of the selected area, instead of searching for specific ones as I try to find all data related to what I want after, isn't it ? To check what keys are present on the area also.
Ineed, you are correct.I though you were trying to only create a terrain, 3d buildings and maybe find some school or similar 3d building, for these two locations. The recommendation I mentioned previously is due to shapefiles having a limit (2044) to how many keys it can contain. This requires further testing of some big cities locations with maybe larger radii, which I haven't performed due to my poor PC configuration. But in theory, I imagine that it may happen that a downloaded .osm file may have more than 2044 keys. In that case shapefile will only record 2044 of them, and disregard the others. That was my point.But again 2044 is a lot of keys, and I haven't been checking much this in practice. For example, when I set the radius_ to 1000 meters, and use your "3 Rue de Bretonvilliers Paris" location I get around 350 something keys, which is way below the 2044.Another reason why one should use the requiredKeys_ input is to make the Gismo OSM components run quicker: for example, the upper mentioned 350 something keys will result in 350 values for each branch of the "OSM shapes" component's "values" output.Which means if you have 10 000 shapes, the "OSM shapes" component will have 10 000 branches with 350 items on each branch (values). This can make all Gismo OSM components very heavy, and significantly elongate the calculation process.With requiredKeys_ input you may end up with only a couple of tens of items per each branch.Sorry for the long reply.…

le of weeks. But if you are patient I think we will try to solve most of the issues.
For the TOF module, I find that no matter which inputs I provide, the optimalTilt is always 45 and the optimalAzimuth is always 180. I'm providing a weather file input and a north vector.
You are the second user who reported this which means that I was wrong in my assumption of setting a very low default value for the precision_ input, it should have been higher as more user friendly for beginners. Basically the TOF component results depend on the precision_ input. The best would be to set this value to 100, let your PC run the whole night, and in the morning you would get the most precise tilt and azimuth optimal angles. However, as some of us are using weaker PCs, and as sometimes the difference between results from precision_ = 100 and say precision_ = 30 is less than a degree, you can try using the precision_ = 30 for the start.
By default the precision_ is set to only 2. I will make sure this is increased in the next release of this component. Your topic definitively contributed to that!
Another thing I noticed is that "TOF" component does not support north_ inputs not equal to 0, in terms of graphical representation of results. It would probably take me some time to fix this. But the numerical results (which is what we need) are supported.
By looking at some other similar PV applications, I haven't seen the optimal tilt/azimuth graphical representation which supports change of north angle direction, so maybe this is not too much of an issue after all. The important thing is the numerical part, which is outputs correct results.
I'm then using the optimalTilt and optimalAzimuth outputs to supply the PV_SWH_SystemSize inputs for arrayTiltAngle and arrayAzimuthAngle - obviously this isn't actually doing anything useful at the moment as the outputs from the TOF are always 45 and 180.
It will make sence now, that you increase the upper precision_ input.
With the PV_SWH_SystemSize module, I'm having issues with the spacing it is providing between the rows of PV. I know it calculates this based on the sun position on a date based on the altitude of the location the weather file provides, but I think the spacing is far too large, especially for a rooftop array where the space is more like 1-2m normally. I'm trying to specify a summer date in the format the minimalSpacingDate output provides (15 NOV 15:00) so the calculated spacing is lower, but it just throws up an error whenever I do.
minimalSpacingPeriod_ input of the "PV SWH System Size" component accepts data from Ladybug "Analysis Period" component. But again, I apologize: as this is my mistake for not mentioning this in its docstring (that's the explanation you get when you hover your mouse over this input). I will make sure this gets added to the next release of "PV SWH System Size" component as well!
I also noticed a bug with "PV SWH System Size" component - at the moment the values it calculates are not correct if north_ input is not equal to 0. This is due to the component using another Ladybug developer's code which calculates sun position angles. For some reason this code does not support changing the north angle direction. I will contact the author to see how this can be solved.
So to be clear: it's not that all Ladybug Photovoltaics component do not support north_ inputs not equal to 0. It's that "PV SWH System Size" component currently does not due to the upper issue. And "Tilt and Orientation Factor (TOF)" component does not support for its graphical representation of results. I will see if at least the first one can be fixed.
Finally, it would be really useful to be able to get the PV_SWH_SystemSize component to actually produce the array it has created as Rhino geometry, so they can be viewed when rendered; is that possible? Also, is it possible to restrict the module so that it only creates rows with dimensions such that it fits within a surface you provide?
The PV_SWHsurface output of "PV SWH System Size" component contains Grasshopper geometry of all PV rows. Are you familiar with baking in Grasshopper?
I attached below an example of how to perform a shaded PV analysis. I rotated the whole context by 40 degrees so that the issue with "PV SWH System Size" component could be overlooked. When you determine your minimalSpacingPeriod_ input, we can internalize its "PV SWH System Size" output, rotate back your context and use "40" as a value for north_ input for all components.
Let me know if something was not clear, or if I replied vaguely to some of your questions.I apology in advance if it may take me a bit longer to answer to your next question. This spring period has really toughen my free time.…
rent actors to work together in real time on an architectural project.
DixieVR was born from the idea that virtual reality could become a fantastic tool for architecture and architects, not only for virtual tours but for the conception at its very core. Inspired by the efficiency of sandbox games, DixieVR will allow you to build a fully parametric 3D model from scratch in a very intuitive way and to simulate various factors like natural and artificial light, gravity, and more. DixieVR is also multi-user oriented : several people, architects or not, are able to work together in real time on the same 3D model and in the same shared immersive environment !
The project started in the Digital Knowledge department of Paris-Malaquais Architecture School.
The DixieVR Softwares can be found here : dixievr.github.io
// Interoperability
DixieVR deals with .dix files. For more information about this file format, please refer to the Interoperability documentation of DixieVR.
You can use this DixieIO plugin for Grasshopper/Rhinoceros for exchanging data between DixieVR (PC) & DixieViewer (Android).
You can import or export objects at any time inside a DixieVR scene. The Software also come with a library of premade objects that you might find useful. Adding your own premade objects to this library might be a good habit.
If you are hosting a scene, you also have the choice to open a .dix file directly from the main menu, this will load the last scene in which the geometry has been saved.
// Plugin
The DixieVR Plugin can be found in the Extra tab, come with 3 components and a example definition:
Dixie2Gh : Import DixieVR geometry to Grasshopper/Rhinoceros reading a .dix file (up to 1000 beams and/or 750 faces).
G2D_Polylines : Export Grasshopper/Rhinoceros Polylines to DixieVR writing a .dix file (up to 1000 line segments).
G2D_Mesh : Export Grasshopper/Rhinoceros Mesh to DixieVR writing a .dix file (up to 750 triangulated faces).
To install:
In Grasshopper, choose File > Special Folders > Components folder. Place the DixieIO_01.gha file there.
Right-click the file > Properties > make sure there is no "blocked" text.
Restart Rhinoceros or Unload Grasshopper.
