Suggestions

Hey dude, good work.

I've wondering if you plan to add eventually:

• line thickness
• line style { dotted ... , slashed _ _ _ , dotslashed . _ . _ . and/or others }
• line alpha lerp { lerp between 0.0 at midpoint and 1.0 at every edge }

keep up the good work

Thanks @r-lyeh!

I can see how that can be useful for debugging, but wasn't planning on adding anything new at the moment. I might give it some priority though, if people are interested on those features...

I think those features wouldn't be hard to implement and can be added on the library side without changing the existing interfaces.

Line thickness might be a bit of a problem though. If it is just passed on to the user renderer then it would have to be a hint, since not all platforms and rendering APIs support configurable line thickness. OpenGL in particular has poor support with glLineWidth. Or optionally handle it on the library side by drawing a stretched quad when thickness != 1.

Nice ideas there.

One more suggestion:

• 2D shapes { circle, rectangle, triangle, arrow.. } in both ortho and projected perspectives.

More ideas:

• Grid with semi-transparent lines; and solid thicker lines on axes.
• Grid with very thick lines on axes, medium thick every X units, else regular thickness.

It would be handy to support 3D gizmos as well, as seen in:
