I’m probably doing something wrong here, but when I use GL_LINE_STRIP I get a lot of extra lines drawn (see the attached graphic.)
In the top example, I’m storing 4 vertices with GL_LINES in order to draw 2 lines at one position of the grid. And this is drawing correctly.
When I use the GL_LINE_STRIP primitive mode, I think I have to store only 3 vertices (in this example) to draw the same 2 lines at one position of the grid.
However the bottom graphic shows a lot of extra lines drawn.
I have the same issue when trying to use the GL_TRIANGLE_FAN.
btw, in this example I’m reading CEIL (ceiling weather data) from a netcdf file to generate the binary glTF.
Thanks for your help.
