Unstable work on windows target

I've ported some simple test https://github.com/Beeblerox/openfl-stage3d-perfomance-test
and it works normally on flash and neko targets, but windows target crashes 1 second after application start, and i don't know the source of this problem, since it doesn't give me any information about the problem causing it.

Can't draw more than 2 triangles with the code from demo

Hello! i'm trying to use your lib. It's looking Great, but i have some problems (mostly because i'm newbie with OpenGL stuff).
I've took the code from your demo ( https://github.com/wighawag/OpenFLStage3DTest ) and tried to draw 4 triangles instead of 2 - i've changed only one function in Main class, here is how it's looking now:

private function onReady(event : Event) : Void{
        context3D = stage3D.context3D;
        context3D.configureBackBuffer(stage.stageWidth, stage.stageHeight, 0, false);
        context3D.enableErrorChecking = true;

        var vertexShaderSource =
            "attribute vec3 vertexPosition;
            attribute vec2 uv;
            uniform mat4 modelViewMatrix;
            uniform mat4 projectionMatrix;
            //uniform mat4 matrix;
            varying vec2 vTexCoord;
            void main(void) {
                gl_Position = projectionMatrix * modelViewMatrix * vec4(vertexPosition, 1.0);
                //gl_Position = matrix * vec4(vertexPosition, 1.0);
                vTexCoord = uv;
            }";

        //var vertexAgalInfo = '{"varnames":{"uv":"va1","matrix":"vc0","vertexPosition":"va0"},"agalasm":"m44 op, va0, vc0\\nmov v0, va1","storage":{},"types":{},"info":"","consts":{}}';
        var vertexAgalInfo = '{"varnames":{"uv":"va1","modelViewMatrix":"vc0","projectionMatrix":"vc4","vertexPosition":"va0"},"agalasm":"m44 vt0, va0, vc0\\nm44 op, vt0, vc4\\nmov v0, va1","storage":{},"types":{},"info":"","consts":{}}';

        var fragmentShaderSource =
            "varying vec2 vTexCoord;
             uniform sampler2D texture;
             void main(void) {
                vec4 texColor = texture2D(texture, vTexCoord);
                gl_FragColor = texColor;
            }";

        var fragmentAgalInfo = '{"varnames":{"texture":"fs0"},"agalasm":"mov ft0, v0\\ntex ft1, ft0, fs0 <2d,wrap,linear>\\nmov oc, ft1","storage":{},"types":{},"info":"","consts":{}}';

        var vertexShader = new GLSLVertexShader(vertexShaderSource, vertexAgalInfo);
        var fragmentShader = new GLSLFragmentShader(fragmentShaderSource, fragmentAgalInfo);

        sceneProgram = new GLSLProgram(context3D);
        sceneProgram.upload(vertexShader, fragmentShader);

        var logo = openfl.Assets.getBitmapData("assets/hxlogo.png");
        texture = context3D.createTexture(logo.width,logo.height, Context3DTextureFormat.BGRA,false);
        texture.uploadFromBitmapData(logo);

        var vertices : Array<Float> = [
            -100,   -100,   0,     0,   0,
            100,  -100,   0,     1,   0,
            -100,   100,  0,     0,   1,
            100,  100,  0,     1,   1,

        -50,   -50,   0,     0,   0,
            50,  -50,   0,     1,   0,
            -50,   50,  0,     0,   1,
            50,  50,  0,     1,   1
        ];

        vertexBuffer = context3D.createVertexBuffer(8, 5);
        vertexBuffer.uploadFromVector(flash.Vector.ofArray(vertices), 0, 8);

        indexBuffer = context3D.createIndexBuffer(12);
        var indexes : Array<UInt> = [0,1,2,1,2,3, 0,1,2,1,2,3];
        indexBuffer.uploadFromVector(flash.Vector.ofArray(indexes), 0, 12);

        context3D.setBlendFactors(flash.display3D.Context3DBlendFactor.SOURCE_ALPHA, flash.display3D.Context3DBlendFactor.ONE_MINUS_SOURCE_ALPHA);
        context3D.setRenderCallback(renderView);
    }

So, as you can see, i've done following:

1. added data for 4 additional vertices into vertices array;
2. set the new number of vertices in the createVertexBuffer() (8 instead of 4);
3. set the new number of vertices in the uploadFromVector() (8 as well);
4. added 6 vertex indicies into indexes array (just duplicated existing indicies);
5. set new number of vertex indicies in createIndexBuffer() (12 instead of 6);
6. set the new number of vertex indicies in uploadFromVector() (12 as well)

And it didn't worked for me (it draws only first two triangles, and ignores other).
But if i want to draw one triangle and make similar changes in code (just reduce the numbers), then it works.
So i don't know where is the problem: is it me, or is it library problem.

Thanks in advance, Alexander

Bunnymark

@wighawag Hello, I recently came across this project, and was wondering if it might be ready for worth adding it to this project of mine https://github.com/drkibitz/openfl-bunnymark

I've been trying to get my own version using OpenGLView up and running, but I am totally not there yet.

Let me know when you get a chance, thanks!

need support setVertexBufferAt(i, null), setTextureAt(i,null), setScissorRectangle(null)

Hi wighawag,

Stage3D uses "null" in setVertexBufferAt/setTextureAt/setScissorRectange/.. APIs to release resources. Could you help implement them in openfl-stage3d?

Thank you.
Jian

Problem with setFragmentUniformFromVector on native targets

It seems like it works incorrectly. Here what i have on flash:

and here what i have on cpp (windows):

the code for this test can be found here: https://github.com/Beeblerox/openfl-stage3d-perfomance-test/tree/master/space3d

Context3D's setScissorRectangle() doesn't work on native targets

It is ignored on native targets, so graphics is being drawn without any clipping

no work on flash

E:\user\desktop\OpenFLStage3DTest-master>openfl build project.xml flash

x:11: characters 7-40 : Class not found : com.adobe.utils.AGALMiniAssembler

Stage3D object blocks all other standart display objects on native targets

i can't see any DisplayObject which had been added to stage on native targets (but it works on flash target).
Maybe it is connected somehow with http://www.openfl.org/index.php?cID=11989&ccm_paging_p=1&time=1376130309#msg12694

stage3D's x and y are ignored on native targets

is it there a some error of glsl shader vec3?

i made a 3d framework of openfl stage3d.
but the cpp target not work with light.
https://github.com/matrix3d/native3d.

so i change your project with vec3.find it have some error or not?

var fragmentShaderSource =
            "varying vec2 vTexCoord;
             uniform sampler2D texture;
             uniform vec3 c1;
             void main(void) {
                vec4 texColor = texture2D(texture, vTexCoord);
                gl_FragColor = texColor * vec4(c1, 1);
            }";

can you help code agal 2 glsl?

Is it okay to use this in closed source applications?

Is this still GPL? Or, is it okay to use this code with less-strict licenses like MIT? I've heard that current Stage3D impl is based on the code from this repo.
I've also found Stage3D layer code in https://github.com/away3d/away3d-core-openfl and says nothing specifically about licensing of Stage3D layer.

We've moved source code to OpenFL repo long time ago because we thought it was licensed under MIT license.
@jgranick is now thinking about switching to new code base, partly because of licencing issue, but I cannot switch to that one immediately. So I want to keep using code which originated from this repo.

call to GL.getAttribLocation should be cached

Unknown class Stage3D for cpp targets

Flash target works well, but when I select cpp target (windows/android) compiler says:
Class not found : flash.display.Stage3D
My environment Windows 7 sp1 32-bit, openfl 2.2.1, FlashDevelop 4.6.4.1.
Probably it's openfl syntax issue, may be with it's packages auto substitution "openfl" instead of "flash".
