note to self, also need to change mass matrix input to a function that calculates the *action* of the mass matrix on a vector, to make the solver entirely matrix-free

1. looks the best out of those options, here are a couple of suggestions to increase speed, would any of these work?: - using snprintf to write to a char...

I agree, I don't think using `snprintf` is worth the extra speed.

that does look really nice! I'd be happy to start using this, but would require a bit of work upfront to convert everything

Thanks @Lorjuo. As I recall we turned off the iterator debug mode in msvc because it wasn't playing nicely with our custom iterator `ColumnIterator`. We need to (a) check if...

Trase uses a `Colormap` [class](https://codedocs.xyz/trase-cpp/trase/classtrase_1_1Colormap.html) to map data values to colors. We don't as yet have a mechanism for using a custom colormap, although it should be simple to add...

True. You might be able to set a simple custom colormap to do what you want, for example have a three element color map: ```cpp Colormap my_map(std::vector{ {{1.f, 0.f, 0.f},...

The 3 refers to the 3 color channels in rgb, so to put 6 colors in the colormap it would be: ```cpp trase::Colormap my_map(std::vector{ {{0.f, 0.f, 1.f}, {0.f, 1.f, 0.f},...

I think I know the problem, it is interpolating between the colors you want rather than hitting those colors exactly. You need to set the min/max values of the color...

The [Line](https://codedocs.xyz/trase-cpp/trase/classtrase_1_1Line.html) geometry does not use the color aesthetic. What behaviour are you looking for with the lines? Do you want to create a bunch of different line geometries with...
