Hello,

first PB520 x86 lib ready for testing. You find them on the first page of this topic...

Many thanks!

Hi Michael
thanks for updating, i have downloaded the file Install_MP3D_32_x86.exe , i have tried it on winxp, it still gives the error "PureBasic library missing: Misc"
regards

Hi,

@applepi, you must copy th elib manuelly, the installer Install_MP3D_32_x86.exe works with pb 5.11. With PB5.2 you need this installer an then you copy the file manually. In the future we need 2 installer

Testversion for PB5.20 beta, please copy into the PureBasic5.20\SubSystems\dx9\purelibraries\userlibraries\ folder
http://www.flasharts.de/mpz/PB520/x86/MP3D_Library

@Alexi, Xray... hm i think this could be done with a shader. I will look, it could be a have one for this
hm Instances , yes with the render routines or with the shader, perhaps i can make example for this too

Hi Michael
now it does not issue the error message but gives those 2 errors

possibly by unsuccessful upload, i have downloaded it several times. i suggest zip files better than bare file. any one else have this error with PB 5.20 ??

Hi applePi,

here it comes:
http://www.flasharts.de/mpz/PB520/x86/MP3D_Library.zip

i have checked it with PB 5.20 and these lib works. I think it is a donwload problem too..

Hi Michael
now it works. thank you

Hi Michael, in addition to the question about textures ...
Are you planning to work on display of objects with alpha? Because for me, they look like this:

Posted: **Mon Jul 29, 2013 12:40 pm**

Hi Andyly,

i am working on a feature to add a texture on a texture, but it is not so easy. To copy a texture to a texture is easy, but with alpha modus not. For now you can add a texure on another, but the textures can onyl be not big one. Can you send me two textures for testing please (one background and one to copy it on the background). Then i hav somthing for testing

I am working on a new terrain function too. If you can make a litte demo for me (one/two trees with the alpha problem and the background terrain) i can check the problem an find a solution for you...

Greetings Michael

Michael, 2 files sent to you (to mail), as you asked, with examples.

Hi mpz,it would be great if your functions sush as MP_Create3DText() support unicode.

Michael, can we consider the example MP_Physic_Primitives.pb from C:\PureBasic\MP3D Demos\3DPhysik\ an example about concave geometry physics ?! because i have tried to compile the bullet-2.81-rev2613 engine and there is an example called
App_ConcaveDemo_vs2008_debug and it is almost do the same as your example, i attach the App_ConcaveDemo_vs2008_debug.exe it may need vc++2008 run time
http://www.mediafire.com/?a9ltd7l7a7oqle7
i have checked the file with https://www.virustotal.com and the results are Detection ratio 0 / 45
its output like this

the same as your example output http://www.flasharts.de/mpz/Physic.JPG
from your link http://www.purebasic.fr/english/viewtop ... 90#p414292
i am still don't know how to do Gears in bullet since my C++ are little
in fact my main purpose is to run Gears, i will do more experiments with your example to see how much it will go with concave concepts.

@leonhardt: i have used Google SketchUp 8 to make a model for chinese sentence (karate school) after translating it by google translator, but after i have installed the chinese fonts, it has this feature in Tools -> 3D Text

Dear applePi,

i am sorry but i dont understand, how i can help you?!?

With mp3d it is possible to change the vertex coods of a mesh and this can actualized with the Physic engine. So it is possible to make a demo like your App_ConcaveDemo.

In the next mp3d version i have newton dynamics 3.1 included. This will be faster physics as the last version of mp3d. For now i have only 10% includet of the newton physic functions. Water and car Physic will be one of the next steps...

Greetings Michael

Hi Michael
good news that you want to update to newton dynamics v3.1 and to add more functions
my wish if it is possible in newton dynamics to implement Gears, so the teeth of every one can go inside the other like the old clock, it is not possible to do this in bullet physics used in purebasic engine unless we choose its preperty as static and we want the gear to be dynamic. look here for the gear in ogre bullet, it is impossible to go inside between two tooths.

so since you are going to newton dynamics 3.1 in the future, if you can make the 2 Gears tangled and the second gear rotate by the effect of the first gear, then will be great. there is one thread in newton dynamics forum http://newtondynamics.com/forum/viewtop ... ars#p50537 in which someone was trying to simulate gears and he ask what collision hull should he use for this purpose? and someone replied him: You want a compound collider --> http://newtondynamics.com/wiki/index.ph ... s#Compound
so if you can implement that compound collider then may be we can make Gears
the following is a Gear 3D for MP3D based on a formula from matheworld http://mathworld.wolfram.com/GearCurve.html
it is useless in the context of my wish , i just want to celebrate your good news about newton 3.1 . use arrow keys and space to rotate.
save this texture to the same folder as the code
