Object rotation vs. world axes

[Peter Dym]

Thank you for the offer to process my plane.
The zip size exceeds 64  kb allowed here for the attachement. So one texture is missing (mig29wave0.png)- you can use any png  256x256 and I will replace it. If you let me know the address where I can send the whole stuff I will do that.
Thanks again.

...and here is the example of my cripled plane and your matrices interpolation :

(2 rockets are lunched to the target. If the target is damaged by the first rocket the second one is recalculating the path and turning to the second target)

Hi Egon,

this can finally be another project using jPCT-AE. A beta version but already exists and almost all problems are resolved.

Looks cool! I'll add the missing projects including this one to the website during the next week..

Hi Egon! I am back to my Airdroid project and want to continue and finish it. I have one problem now which is blocking me a little bit. It is a blit function which does not work like I am expecting. What I need is to have a bitmap with a few pictures and to blit a part of the bitmap to the fb. So I have:

   fb.blit(intArray,bitmapwidth,bitmapheight,0,0, 100,100, partialdx,partialdy, FrameBuffer.TRANSPARENT_BLITTING);


I am expecting that there will be rendered a part of my bitmap started from 0,0, with a width and height =partialdx, partialdy at position 100,100.

But the result is that the whole bitmap is always rendered onto fb. Regardless of partialdx, partialdy.

What I am doing wrong?

Regards,

Peter.

What I am doing wrong?

Nothing. There was a typo in the Android port of that method that prevented width and height from having any effect. Here's a (maybe, i haven't tested it...) fixed version: http://jpct.de/download/beta/jpct_ae.jar

However, i strongly advise not to use this method if possible...it can be a huge performance bottleneck. If you have to use it, check if you can use http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#glUseIgnorantBlits in addition.

Thanx, "strongly advised" from author means a rule. So I am using a texture now. I just wanted to save one texture and to have a big bitmap with all controls/buttons/icons.
