Hi, I am working on a 2d strategy Game!
For rendering the Graphics I use draw_quad(), because its faster than with panels for my purpose.
Now I want to include a zoom function. First I tried with scaling through the draw_quad() function, but if I scale the grapfics smaller i have an aliasing effect, the graphics don't look good. I think I need a filter, but how...?
I tried with rendering the pgraphics on a bmap... creating a bmap, useing bmap_rendertarget() and set the bmap to a panel with Filter flag. Now I am able to scale the Panel and with it the whole rendering. but the problem is, that draw_quad() is not working outside the window... if I zoom out I have following problem:



Does Anyone have an Idea to work around?

I don't have a direct solution for your problem but have you thought about using sprites and ISOMETRIC rendering?

Yes I have throught about it. I want to make a traditional 2d game and there should be a possibility to transfer it to other platforms and Browser without a 3d engine. I've not planned it yet, but I want to have the option. This are the two reasons.

So I'm serching a solution for my problem...

Can you run a scene-screen anti-aliasing.
d3d_antialias = 4 or 9; // activate scene antialiasing

or
Postprocessing shader

Was it Helix that posted a scene space AA shader with his bloom shader long ago?

So that's me guessing. Maybe it will be helpful

I think this is not working. d3d_antialias I tried also, but not working. I have no Level loaded so Im not using a view.
I have just the engine window.
But how is the FILTER flag of Panels working? Is it possible to have something like the Panel FILTER flag for the whole window?

Ok some more info I should have looked up

Now I can assume somethings. Panels are created with dx9 function. Direct_3d because direct_draw was removed. To get a good understand I'd have to ask the dev. There are some flag like settings I found looking up d3dx9 and maybe this filter flag is just on of them. I assume we can access dx9 so should be able to it turn a anti aliasing for d3d quid. But I'm all guessing

@^: Antialiasing doesn't affect texture quality. Anisotropic filtering does, but I'm afraid you can't get draw_quad to use a specific texture filtering method (or a custom shader which would allow even more possibilities).

@Kartoffel - Thanks for bring this out the muddy water of my guessing.
If this is a as you say

Does that make the quad surface a texture in the nature of engine entities? So can his quad use some kind of manipulation of the mip-map system to blur the texture when he "zooms - out" or rather scales down the quad?

Of course that would not give great results.

@O.P> bmap_rendertarget leads to view.bmap http://www.conitec.net/beta/aview-bmap.htm
which leads to bmap_zbuffer(BMAP*)
http://www.conitec.net/beta/bmap_zbuffer.htm
which leads to render_zbuffer
http://www.conitec.net/beta/render_zbuffer.htm

This chain, as I understand is a way to create a render target larger then the screen and render into a bmap larger then screen. However this my just be my confusion.

Also not sure how you create a engine-ambiguous 2d game using any 3dgs engine commands. Wouldn't you need to write it directly in openGl. also is it even possible to create a web based game and windows game with the same code in any library?

But ok, Have fun!

hm I'm looking into the possibilities of unity :-)

I am back. Really used to A8...

I tried with increasing the zbuffer, but its still not working
