Flexible Vertex Format - special SVN branch is ready!!!

[Nadro]

It looks like a bug in an Octtree Scene Node, I will look onto a bounding box creation process methods once again. Thanks for a report. I will add a doxygen style comments in a header files soon, because You're right that this is an important part of an each project.

when compiling for windows from c::b I get these errors (just launched compiling using the project file inside the source folder)

I fixed compilation errors in a rev4113.

[REDDemon]

wao there are lots of extra lines of code and compiling is taking very long.

...

Finished to compile.
Got compressed textures working also with your branch in the last revision
(the loader code needed no changes, but the example required few changes )


Here's the custom scene node example with compressed textures support enjoy. (compressed textures + FVF )

Great patch Nadro everything worked like a charm (tried most of examples randomly)

[REDDemon]

I found few bugs (all related to Code::blocks+mingw projects files and EDT_OPENGL as driver).. I hope to not be boring.

05 - this example simply setted as output directory "gcc" instead of "win32-gcc".

08 - Special FX example has buggy shadows (already noticed)

10 - Shaders example Cg shaders are not working at all (all the 3 cubes are identical)

16 - this example is linking with Irrlicht.lib instead of libIrrlicht.dll.a

19 - same problem as 05

21 - this example don't compile it says "main.cpp" line 1171 error: invalid conversion from 'int' to 'const wchar_t*'"

23 - same problem as 16

all other examples worked

[Nadro]

Thanks for info. What about Code::blocks+mingw projects? I use version from a trunk, so we should first fix a file project in a trunk I have one question for example no. 10? Did You compile Irrlicht with a Cg support? Cg isn't enabled default. If not, this is a normal behaviour for this example.

[REDDemon]

ah !:) thx

[Mel]

I am also testing this with the CG languaje support disabled, is it better to have it or not?

[fmx]

Depends if you want to use CG or not
I like CG, only have to write shaders once and they work regardless of driver

[Nadro]

Bug in a Demo example is fixed. Currently it looks like a FVF implementation is a bugs free.

Thats why I said "Currently it looks like a..." I mean that known bugs list is now empty I'm 99,(9)% sure that in future we'll found many bugs in FVF

Yes, but i was wondering if there was any kind of dependency between the FVF system and the CG system.

[Nadro]

No, there is no a dependency between a FVF and Cg.

is pretty stable for a so huge patch anyway. .
