Re: Math Library (with iqm animation demo)

Thanks, there must be more typos and mistakes
It should have been function quat.from_rot(r, a, x, y, z) like (mat4.rv etc) to begin with

Math Library (with iqm animation demo)

https://github.com/monolifed/lua-module ... main/vmath (MIT Licensed)

Library is a port of my C library: https://github.com/monolifed/vmath (Unlicense)

IQM animation demo is modified to use this library (replacing cpml)

Re: Bizarre nil issue

x = notes[x][y].x0 -- x is never affected by this bug... y = notes[x][y].y0 -- somehow this can set y to nil even though I've just shown a non-nil value for y0... first statement sets x to notes[x][y].x0 but the second sets y to notes[notes[x][y].x0][y].y0 Not notes[x][y].y0 You can do x, y = notes...

Re: Easings Preview

Thanks Yes very slight but there and compared to smootherstep it becomes very noticeable. polynomial outin functions seem to be smooth but all inout ones have that problem One solution is adding a higher degree polynomial that resembles the piecewise inout function (Like the smootherstep you provide...

Re: Easings Preview

I understand that they are not mathematically smooth but I am yet to see visual artifacts caused by it, Feel free to provide an example That said I am not inventing new functions here. They are some standard functions and some other functions from easings.net If they are not smooth there is nothing ...

Re: Easings Preview

Yes they (InOut ones) don't seem to have continuous second derivatives.
Interestingly leap from acceleration to deceleration doesn't seem to affect smoothness of the transition noticeably

Re: Easings Preview

Which ones are not smooth?
bounce is clearly not
elasticOutIn, expoOutIn also not
Anything else?

I can add smoothstep
I think its out version can be

Code: Select all

f(x) = sqrt(x * (x - 1) / 3) for x < 0.5
1 - f(x - 2) for x >= 0.5


Thinking again, smoothstep is more like an InOut function

Easings Library

I am writing yet another easings library

smoothstep 1 to 6
polynomial 2 to 6
circle, sine, expo
back, elastic, bounce

Re: video:play() issues

It worked with seek(0.1) and bgv1_4.4.ogv everytime I tried.

I also re-encoded your bgv1_4.4.ogv with ffmpeg 4.3.2-0, it seems to work.

Code: Select all

ffmpeg -i bgv1_4.4.ogv -c:v libtheora -q:v 10 -c:a libvorbis -q:a 5 bgv1.ogv

Re: video:play() issues

I don't know what is wrong.
But the following seems to work as a work around.

Code: Select all

local video = love.graphics.newVideo("bgv1.ogv", {audio="true"})
video:seek(0.1) -- added
