BGBTech: The Status Update

random: video upsample and enhance...

Posted by BGB, 24 September 2013 · 646 views

well, this was another experiment... (possibly a waste of time, but oh well...).

I had an idea for a tool idea to experiment with:
a tool which will take input video, try to up-sample it in a way which "hopefully doesn't look like crap", and save output video.

basically, it just decodes frames from one video, and then resamples and re-encodes them into...

new experimental video codec, BTIC1C...

Reused text...

Once again, it is a codec intended for quickly decoding into DXT for use in animated textures and video-mapped textures.

It is a direct continuation of my effort to implement Apple Video, but with a slight rename.

I ended up calling it BTIC1C as it is (despite being based on Apple Video), still within the same general "family" as m...

Planets, and Apple Video...

I have decided to change my voxel engine from being an "infinite" 2D plane, to being a bounded 2D region, which I will assert as being a "planet".

this basically consisted of adding wrap-around, and generating a topographical map for the world.
currently, the world size is fairly small, roughly a space about the size of the surface of Phobos, or...

Bounds-checking? in C? it would appear so?... (sort of...).

bounds checking, c++
well, here is something unexpected.
I have yet to generally confirm this, or yet did any real extensive testing to confirm that what I have encountered works, in-general, but it appears to be the case at least in the cases encountered.

(I can't actually seem to find any mention of it existing, like somehow encountering a feature which should not exist?.....

complexity and effort-budget...

Posted by BGB, 11 September 2013 · 345 views

idle thoughts here mostly:
project complexity is not nearly so easily estimated as some people seem to think it is;
time budget is, similarly, not nearly so easily estimated.

there is a common tendency to think that the effort investment in a project scales linearly (or exponentially) with the total size of the codebase.
my experiences here seem to imply...

otherwise: new codec, BTAC 2A

audio, codec, compression, BTAC
Some info available here:


this is basically a codec I threw together over the past some-odd days (on-off over the past 10 days), probably a solid 3 or 4 days worth of implementation effort though.

it was intended to try to have a better size / quality tradeoff than my prior BTAC, but...

working backwards: A 2D platformer game?...

Posted by BGB, 01 September 2013 · 609 views

(started writing a post, but not sure if this makes much sense as a post...).

currently, I have a 3D game (FPS style), but also a bit of a problem:
it kind of sucks, pretty bad;
I don't think anyone really cares.

I also have a few drawbacks:
not very good at 3D modeling;
I am worse at map-making (hence... why I ended up mostly using voxels...).

but, I...
