[question] How to display an array of pixels? about dgame HOT 15 CLOSED

I would try the vertex array class:
http://dgame-dev.de/?package=Graphics&module=VertexArray
http://dgame-dev.de/?page=tutorial&tut=vertex_arrays

Otherwise the VertexRenderer:
http://dgame-dev.de/?package=System&module=VertexRenderer

from dgame.

If you doesn't want a Shape, you could also try to load your Pixel in a Texture/Surface.

Can this be closed?

In what format should I load memory with this function? I use Texture. final void loadFromMemory(void* memory, ushort width, ushort height, ubyte depth, Format fmt = Format.None);

Could you give me more code? Currently I don't see what you want.

from dgame.

Now I have:

Color bitmap[1024][768];
Texture screen = new Texture;
Sprite sprite = new Sprite(screen);

void draw_bitmap()
{
screen.loadFromMemory(&bitmap, 1024, 768, 24, Texture.Format.RGBA);
}

void Render()
{
sprite.setTexture(screen); // I think this isn't right :)
wnd.draw(sprite);
}

I want to change pixel data manually, and display it on the Window with hardware acceleration.

Have you tried Texture.setColorkey? You could also use Texture.getMemory. The latter could be converted to your Color array. You can use the setcolorkey code for inspiration: https://github.com/Dgame/Dgame/blob/master/Graphics/Texture.d#L470

What is your main intention?

Have you tried Texture.setColorkey?

Yes, I got this: https://dl.dropboxusercontent.com/u/76682625/Trash/shot1.png
Is it OpenGL issue? I have Intel HD Graphics 4600 on Linux Mint 15, maybe there is some bugs in drivers or incomplete support (i didn't find drivers, but TF2 runs fine, as example).

What is your main intention?

Pixels are not rendered correctly.

You could also use Texture.getMemory.

Thanks, I'll try it tomorrow.

Which Dgame version did you use? If it's the bug I think about it was fixed here: 59fff01#diff-a351c750b91f11d1a9b2fa332a3c3f0cL448

Sorry, it was my fault. Now it works almost perfectly, but there is some strange bug.
It appears randomly in ~30% of cases.

My code:

Color bitmap[768][1024];
Texture screen = new Texture;
sprite = new Sprite(screen);

        foreach(ref map; bitmap[])
        {
            map = Color(67,0,67);
        }

        for(int x=0; x<1024; x++)
        {
            for(int y=0; y<768; y++)
            {
                bitmap[y][x] = Color(30,30,127, 127);
            }
        }
        screen.loadFromMemory(&bitmap, 1024, 768, 32);
        sprite.setTexture(screen);
        sprite.setPosition(0,0);
        wnd.draw(sprite);

You mean this artifacts? The blue triangle?

You mean this artifacts? The blue triangle?

Yes, this triangle. On a plot of the screen with this triangle, pixels doesn't update.
In this video my code is

        foreach(ref line; bitmap[])      // clear bitmap
        {
            line = Color(67,0,67);
        }

        /* render 3d points */
        /* write it on a bitmap */

        screen.loadFromMemory(&bitmap, 1024, 768, 32);        //load bitmap on a Texture

        sprite.setTexture(screen);        //load Texture to Sprite
        sprite.setPosition(0,0);
        wnd.draw(sprite);  //and show it

This seems more like a bug with your graphics card driver. You should update them. Otherwise you could try to extend glClear in Window.d: https://github.com/Dgame/Dgame/blob/master/Window/Window.d#L358
Enable the outcommented GL_DEPTH_BUFFER_BIT or try some other: http://wiki.delphigl.com/index.php/glClear
But from my point of view it looks almost as a driver bug. Which graphic card did you use? And could you try it on another computer?

But from my point of view it looks almost as a driver bug.

I think same.

Which graphic card did you use?

Intel HD Graphics 4600 (built-in Intel i7 4770k). I didn't find official drivers for Linux, and I use built-in drivers from Linux Mint 15. Maybe this is a reason why it doesn't work correctly.

And could you try it on another computer?

I'll try it today or tomorrow.

Anything new?

Sorry, nothing. I still have not tested this, and not sure if I'll have time to do that.
