Hi there, i have a question which is possibly more of a generic VTK question than specifically about Mayavi, but i'll see if anyone can offer me some quick advice.
I have data outputted from a model arranged in a x,y,z grid. the x and y grid is the same for all z levels, but the actual z values for each point with the same z grid index varies.. that is, the actual z value (in meters) of a cell varies across the same integer z value (between the other x,y's). i hope thats clear. so i have 3, 3d variables for my x,y, and z data.. and i build a dataset like this: mlab.pipeline.scalar_field(x, y, z, scalars) however i see that it results in an ImageSource, and if i test to visualise a dataset that is zero for all z values except one where it is one, i see a flat plane, when i should see the varying z values for that z level. if i try to use a scalar_scatter, i get the results i expect when i visualise using glyphs,(each z level follows the expected terrain), but then i cannot to iso contours or cut planes, i think because i have lost my connectivity info. running a delaunay 3d filter on the scalar_scatter output gives me the results i need.. but it takes a long time and i feel like i'm missing a better way to do this. any ideas would be appreciated, i hope this makes sense. thanks -i ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
