| This looks super fun.

|
| The graph on the chart I shared suggests that the peak of

| changes since then. This doesn't make much sense to me, as
| the rendering quality looks great (at least in the videos--
| I'll try the software a bit later), and it's head and

| What's your specific concern? You're making a very strong

| evidence. Furthermore, the project "stalling" makes it
| less... what, exactly?
| mturk wrote:
| I don't think that it's fair to compare the rendering to
| what is currently in use in the scientific community, for
| two main reasons:
|
| The first is that different types of rendering have
| different uses; typically in scientific visualization this
| is broken down into essentially "viz for self, viz for
| peers, viz for others" and oftentimes the most well-used
| rendering engines are targeted squarely at the first and
| second categories. The visual language in those categories
| is qualitatively different than that used for more "outward
| facing" renderings.
|
| The second reason is that I disagree with your assertion
| about the quality of the visualization techniques in use
| within science. There are some truly spectacular
| visualization engines for cosmology and galaxy formation --
| just to pick two examples off the top of my head, the work
| done by Ralf Kaehler or that by Dylan Nelson. (There are
| _many_ really good examples, however, and I feel guilty not
| mentioning more.)
|
| As I said in another, rather terse and unelaborated
| comment, though, this is really, really impressive work. I
| think it's important that in praising it, however, we don't
| discount the work that's been done elsewhere. This need not
| be zero-sum.

| The bullshit amounts of churn-for-the-sake-of-it in the
| JavaScript ecosystem aren't normal.
