Release Minetest

[ptitSeb]

Here is a recent version of Minetest.

It has been requested to have a freshen build of Minetest. So here it is. I know there is another built, this one is not an update.

/!\ on CC model, it will not work with default driver, use lastest 4.04 for good result /!\

[___]

any performance increases on a cc pandora?

any performance increases on a cc pandora?

it should be fast enough, with some slowdown sometime (probably when loading chunks).

Try it and report, as I haven't much myself.

will do! thanks for all the porting goodness!

 

[mongrol]

Hrmff, and once again I'm tempted to spring out the soldering iron to fix my busted nubs.

Hi !

@ ptitSeb: thanks for porting Voxelands and Minetest to the Pandora

With some OC @ 850MHz the speed is okay-ish on my Rebirth unit, but both games suffer from the same issue: **huge clipping**

Is there anything you can do about that ?

Cheers, Magic Sam

 

[ptitSeb]

I'm not sure I understand. I see in my screenshot the clipping is quite far. You don't have that? Is it the chuks taking time to load?

 

[Magic Sam]

Sometimes I just seem to reach the edge of the world, starring at nothing but black void. Then, after quite some time, a huge chunk of landscape will pop up in front of me... Any idea where this issue could come from ? Cheers, Magic Sam

Lack of CPU power? 

 

[Magic Sam]

@ ptitSeb: You're right. Notaz' Live System Info indicates Minetest uses 100% CPU resources, even with OC @ 850MHz...

Could this be improved ? Cheers, Magic Sam

p.s: I turned all the eye candie off, to no avail

 

[ptitSeb]

Well, I think I have already activated all perf optims.

Here a screen shot of the PVRTune tool. You see that CPU is 100% and GPU is ... what, less than 20%.

And a sudo perf top also, where you can see, no clear function to work on...

 

[Magic Sam]

@ ptitSeb: I managed to lower the CPU load quite a lot with these options in minetest.conf:

wanted_fps = 5

fps_max = 10

viewing_range_nodes_max = 40

viewing_range_nodes_min = 8

enable_fog = true

new_style_water = false

enable_clouds = false

menu_clouds = false

enable_sound = false

 

Yet, the clipping issue is still there

 

EDIT: some more interesting options:

 


fullscreen_bpp = 8

show_debug = on

directional_colored_fog = false

chunksize = 1

 


Cheers, Magic Sam

Aside from the artifacts, it is playable on a 1Gh.

Artifacts from default drivers?

 

[FBnil]

yes. default drivers.

also: has more fps than voxelands (http://repo.openpandora.org/?page=detail&app=voxelands_ptitseb)

Hi

I overclocked my Rebirth unit to 1GHz/OPP5, but the clipping effect is unfortunately still there...

Question: would the perlin noise algorithm be worth optimizing ?

Cheers, Magic Sam

Because it's one of the top function in the perf top?

I haven't looked at the function, so I don't know if it could be easy or not.  I may try a bit later.

The ciipping is part of the game. It constructs areas progressively, especially in the beginning. nothing unusual there.

By the way PtitSeb this PND deserves better screenshots

I agree about the screenshots, but I suck at this kind of game, as you can see

But if someone as nice one, I'll change them

 

[Magic Sam]

@ekianjo: I played Minetest before, and the clipping effect was not **THAT** strong

@ptitSeb: according to Wikipedia, perlin noise can be quite demanding sometimes. There's another, simpler noise algorithm, Simplex noise, but that one is patented though...

p.s: Craft seems to be using Simplex noise, maybe you could borrow some code from it.
