[GRASS-user] 3D raster color coding

[Francois_Chartier]

Hi,

I have created a 3D raster from soil properties with about 70K points, with a lot of help from the mailing list i must say.
from the copy of the metadata of the 3d raster (below) it would confirm that the 3D raster worked and the grid is populated with data.
I have copied below the r3.colors and assigned ‘aspectcolr’ as a trial. Unfortunately in the Display window nothing shows up, whether in 2D or in 3D view. I do not know what i am doing incorrectly.

Once I am done and able to develop the 3D raster of the soil properties, I will prepare a simple step by step for developing such a raster which may be useful for others.

Hello,

That’s probably because that palette is for integer values ranging from 0 to 360 [0]. Try with a relative one such as viridis or bcyr.

Try removing -r from your command (unchecking the box in the GUI).

That flag is used to remove a color palette.

i removed the ‘r’ and used elevation and bcyr as the color tables, see below. Display window is blank.

to recap the steps:
1 - i selected the Mapset and also tried Map that corresponds to the 3d raster
2 - then in Define tab, i only choose the Name of Color Table: bcyr, i have not selected anything else,
3 - then i just Run.

What about the region? Is it set to the extent of your raster?

That’s probably because that palette is for integer values ranging from 0 to 360 [0]. Try with a relative one such as viridis or bcyr.

Hi,

I have created a 3D raster from soil properties with about 70K points, with a lot of help from the mailing list i must say.
from the copy of the metadata of the 3d raster (below) it would confirm that the 3D raster worked and the grid is populated with data.
I have copied below the r3.colors and assigned ‘aspectcolr’ as a trial. Unfortunately in the Display window nothing shows up, whether in 2D or in 3D view. I do not know what i am doing incorrectly.

Once I am done and able to develop the 3D raster of the soil properties, I will prepare a simple step by step for developing such a raster which may be useful for others.

how do you ensure that region is selected to the extent of the raster. I think I already did this when making v.vol.rst.

Hi Veronica,

Hi,

I have created a 3D raster from soil properties with about 70K points, with a lot of help from the mailing list i must say.
from the copy of the metadata of the 3d raster (below) it would confirm that the 3D raster worked and the grid is populated with data.
I have copied below the r3.colors and assigned ‘aspectcolr’ as a trial. Unfortunately in the Display window nothing shows up, whether in 2D or in 3D view. I do not know what i am doing incorrectly.

Once I am done and able to develop the 3D raster of the soil properties, I will prepare a simple step by step for developing such a raster which may be useful for others.

Unfortunately in the Display window nothing shows up, whether in 2D or in 3D

view. I do not know what i >am doing incorrectly.

I have pasted below the colors files for the 3d raster. the screen capture shows that the data is there as i am showing the wireframe around the data. the r3.color is set to bgyr. therefore, i do not see how come the interpolated data does not show up in the display.

the vector is visible in 3d as per attached screen shot. could this be a problem due to computer instead of Grass. there may be too many data points to show?

I sent you some time ago a video how to view 3D rasters using isosurfaces or slices:
https://youtu.be/CmK-fEyf2SY

If you haven’t added any isosurface or slice, you won’t see anything beside the 3D box.

Also, I recommend setting higher z-exaggeration.

that worked! thank you. i can see the data using 3D view, in data tab, select 3d raster at bottom (scroll down), select 3d raster, draw: slices, shading flat, resolution 1, select wire box.
then i can add slices. I havent mastered the system yet but i think i am on the right track now. thank you very much!

Unfortunately in the Display window nothing shows up, whether in 2D or in 3D
view. I do not know what i >am doing incorrectly.

see https://trac.osgeo.org/grass/ticket/3571

please add your findings there.

here is a screen shot of the 3D view.

here is a screen shot of the data set, ground surface, top bedrock, data points, 3d raster. still a lot of work but now i can move to the next step

that worked! thank you. i can see the data using 3D view, in data tab, select 3d raster at bottom (scroll down), select 3d raster, draw: slices, shading flat, resolution 1, select wire box.
then i can add slices. I havent mastered the system yet but i think i am on the right track now. thank you very much!

I sent you some time ago a video how to view 3D rasters using isosurfaces or slices:
https://youtu.be/CmK-fEyf2SY

If you haven’t added any isosurface or slice, you won’t see anything beside the 3D box.

Also, I recommend setting higher z-exaggeration.

the vector is visible in 3d as per attached screen shot. could this be a problem due to computer instead of Grass. there may be too many data points to show?
