Migrating Unigine 3D Engine to Java #889

eix128 · 2020-05-30T23:56:29Z

Hi , i have downloaded Unigine 3D Engine
https://unigine.com/get-unigine

Then i wanted to make Binding to Java
I have made the Java File
I got error on 3 files "UnigineString.h" , "UnigineType.h" , "UnigineVector.h"

Here is the command i have tried:

Here is the patched some include files:

I donno what to do ? How to fix "UnigineString.h" , "UnigineType.h" , "UnigineVector.h" files.
1.44 MB 1 big Java file i got out when i disable "UnigineString.h" , "UnigineType.h" , "UnigineVector.h"

But how to fix the issue ?
or i am at wrong way to convert the problem?

The text was updated successfully, but these errors were encountered:

Please try to follow this guide: https://github.com/bytedeco/javacpp/wiki/Mapping-Recipes

And let me know where you are having problems with it. Thanks!

Well okay i started with small includes now,
I got error on UnigineVector.h

UnigineVector.h file is here:
https://paste.ofcode.org/NjVmiiTJB4NWYSAzbTBD3y

Or you can get Unigine Free SDK.

Why EOF Error occurs ? I checked all braces.
There seems to be like no problem on file.

My generator file:

Might be caused by UNIGINE_ALIGNED4(), UNIGINE_ALIGNED8(), UNIGINE_ALIGNED16(), and UNIGINE_ALIGNED128(). Make sure that they don't expand to anything that has strange attributes.

eix128 · 2020-06-04T06:42:29Z

I have found the location of decleration on UnigineBasic.h

UNIGINE_ALIGNED4(), UNIGINE_ALIGNED8(), UNIGINE_ALIGNED16()
/*
*/
#define UNIGINE_IS_ALIGNED4(VALUE) (((size_t)(VALUE) & 3) == 0)
#define UNIGINE_IS_ALIGNED8(VALUE) (((size_t)(VALUE) & 7) == 0)
#define UNIGINE_IS_ALIGNED16(VALUE) (((size_t)(VALUE) & 15) == 0)
#define UNIGINE_IS_ALIGNED128(VALUE) (((size_t)(VALUE) & 127) == 0)
#define UNIGINE_ASSERT_ALIGNED4(VALUE) UNIGINE_ASSERT(UNIGINE_IS_ALIGNED4(VALUE))
#define UNIGINE_ASSERT_ALIGNED8(VALUE) UNIGINE_ASSERT(UNIGINE_IS_ALIGNED8(VALUE))
#define UNIGINE_ASSERT_ALIGNED16(VALUE) UNIGINE_ASSERT(UNIGINE_IS_ALIGNED16(VALUE))
#define UNIGINE_ASSERT_ALIGNED128(VALUE) UNIGINE_ASSERT(UNIGINE_IS_ALIGNED128(VALUE))

/*
*/
#ifdef _WIN32
#define UNIGINE_ALIGNED4(NAME) __declspec(align(4)) NAME
#define UNIGINE_ALIGNED8(NAME) __declspec(align(8)) NAME
#define UNIGINE_ALIGNED16(NAME) __declspec(align(16)) NAME
#define UNIGINE_ALIGNED128(NAME) __declspec(align(128)) NAME
#else
#define UNIGINE_ALIGNED4(NAME) NAME attribute ((aligned(4)))
#define UNIGINE_ALIGNED8(NAME) NAME attribute ((aligned(8)))
#define UNIGINE_ALIGNED16(NAME) NAME attribute ((aligned(16)))
#define UNIGINE_ALIGNED128(NAME) NAME attribute ((aligned(128)))
#endif

So i will try
infoMap.put(new Info("UNIGINE_ALIGNED4", "UNIGINE_ALIGNED8", "UNIGINE_ALIGNED16", "UNIGINE_ALIGNED128").cppTypes().annotations());

Right ?
Or is there any better solution ?

Right ?

No, this: https://github.com/bytedeco/javacpp/wiki/Mapping-Recipes#redefining-the-code-of-a-macro

When i remove the VectorHelper class , error disappears but CPU Usage reached to %50
And project hanged on processing UnigineVector.h

saudet · 2020-06-04T10:16:00Z

Could you try to isolate which line makes it fail?

eix128 · 2020-06-04T11:37:15Z

I got new UnigineVector.h
https://gist.github.com/eix128/4ef19375c73168dca8ad8c1f1882db43

It generated
https://gist.github.com/eix128/fe2f7ae09cc3a2d7fee56eb76559889e

The problem seems
template<typename T, int>
struct VectorHelper

I changed it to:
template< typename T >
struct VectorHelper

PATCH 2:

FROM:

template<typename T, int C, int>
struct Data { char data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C, 4> { UNIGINE_ALIGNED4(char) data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C, 8> { UNIGINE_ALIGNED8(char) data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C, 16> { UNIGINE_ALIGNED16(char) data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C, 128> { UNIGINE_ALIGNED128(char) data[C * sizeof(T)]; };



TO:



template<typename T, int C>
struct Data { char data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C> { char data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C> { char data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C> { char data[C * sizeof(T)]; };

template<typename T, int C>
struct Data<T, C> { char data[C * sizeof(T)]; };

This works but
But i dont see Vector class generated.
Something seems wrong.

eix128 · 2020-06-04T12:02:33Z

It would be good to make javacpp utils like modulating header files.
Seperating header implementation and prototypes.
And for finding error modulate header class files.
These utilities makes javacpp easier to port C++ projects.
More easy to find errors.

…without names (issue bytedeco/javacpp-presets#889)

Thanks! I fixed this issue in commit bytedeco/javacpp@6d84ea7.

You'll need create instances and give them valid names in Java:

I fully agree. We just need someone that has some time to work on this, see bytedeco/javacpp#51.

Okay now , when i tried the Wrapper , I got error Unigine::SystemDialog put into generated Java code.How can i fix this kind of issues ? Why there is no filter? There is no keyword "::" in Java as we know , javacpp can replace automatically from
Unigine::SystemDialog
to
UnigineSystemDialog

also

PtrUnigine::SystemDialog
to
PtrUnigineSystemDialog

        infoMap.put(new Info("Unigine::SystemDialog").javaText("UnigineSystemDialog"));
        infoMap.put(new Info("UNIGINE_INLINE", "ZEXPORT", "z_const", "zlib_version").cppTypes().annotations());

Redefining an Info like that 4 times will only end up with the last value being set. Make sure to set everything on the same line like this, if that makes sense, but it probably doesn't:

         infoMap.put(new Info("Unigine::SystemDialog").pointerTypes("UnigineSystemDialogP")
                                                      .valueTypes("UnigineSystemDialog")
                                                      .javaNames("UnigineSystemDialogK")
                                                      .javaText("UnigineSystemDialog"));

Okay now ,
i just made like this:

public class NativeLibraryConfig implements InfoMapper {
public void map(InfoMap infoMap) {

    infoMap.put(new Info("Unigine::SystemDialog").pointerTypes("UnigineSystemDialogP")
            .valueTypes("UnigineSystemDialog")
            .javaNames("UnigineSystemDialogK")
            .javaText("UnigineSystemDialog"));
}

}

Ptr<Unigine::SystemDialog> is a template instance. You're going to need to give it a valid Java name:

Okay now I have NativeLibrary.java
Here it is:
https://we.tl/t-qDC1Z5biE6

But , its 1MB , all classes generated into 1 file.
I want every class generation to seperate file.
So it will be modular and i will compile each module seperate for more easy fixing problems.

My NativeLibraryConfig.java :
https://gist.github.com/eix128/671d89f70c746bb073e14d3c08ce329a

saudet · 2020-06-06T22:48:59Z

Be sure to set the @Properties(global=...) value, for example, as shown here: https://github.com/bytedeco/javacpp-presets/wiki/Create-New-Presets

eix128 · 2020-06-07T15:53:21Z

Thanks it worked.
Now
generated invalid 2 methods
public class BodyWater extends Body {
...
public static native @byval PtrUnigine::BodyWater create();
public static native @byval PtrUnigine::BodyWater create(@const @ByRef PtrUnigine::Object object);
...
}

What to add to infoMap.put to fix it?

saudet · 2020-06-07T22:36:12Z

Give them valid names, see above #889 (comment)

eix128 · 2020-06-08T10:37:07Z

Nice , now
I have 3 questions :

@namespace("Unigine") @properties(inherit = org.unigine.presets.UnigineConfig.class)
public class Properties extends Pointer {
....
}

Properties class is Unigine::Properties class file
it collides with
import org.bytedeco.javacpp.annotation.Properties;

What to put to "infomap.put" rename class name from Properties to UnigineProperties ?

i put
infoMap.put(new Info("Unigine::Property").javaNames("UnigineProperty"));
but it didnt work

I got

public class APIInterface extends Pointer {
...
public native int isNull();
...
}

public native int isNull();
collides with org.bytedeco.javacpp.Pointer isNull method
How to remove colllision ?

i dont know how to fix method collision with javacpp and unigine

org.unigine.Node class

public native @ByVal vec3 getDirection(@ByVal(nullValue = "MathLib::AXIS(Unigine::Math::AXIS_NZ)") AXIS axis);

AXIS is undefined.
I have looked at it.Its enum type

I tried
infoMap.put(new Info("AXIS").javaNames("int"));

But this also didnt work.

in C++ side AXIS is defined in
UnigineMathLib.h

enum AXIS
{
AXIS_X = 0, // positive axes
AXIS_Y,
AXIS_Z,
AXIS_NX, // negative axes
AXIS_NY,
AXIS_NZ,
};

But JavaCPP cant get enum type

Thanks

saudet · 2020-06-08T22:20:55Z

It's with Info.pointerTypes, like this:
https://github.com/bytedeco/javacpp/wiki/Mapping-Recipes#specifying-names-to-use-in-java

saudet · 2020-06-14T00:19:20Z

To rename methods, we can use Info.javaNames, like this:
https://github.com/bytedeco/javacpp/wiki/Mapping-Recipes#specifying-names-to-use-in-java

You'll need to include "UnigineMathLib.h" in the @Platform(include=... list explicitly for JavaCPP to pick it up. But it's also possible to set it with Info.valueTypes, like this: https://github.com/bytedeco/javacpp/blob/master/src/main/java/org/bytedeco/javacpp/tools/InfoMap.java#L68
