Hi guys,

I just started working with DBPro so bear with these simple questions- I was wondering how to smooth the edges of a 3D model when a program is run? Basically i want to preview one one my 3d models in a game environment. I have managed to get all the objects loaded etc but cant get the nasty jagged line around the straight edges of models to disapear. One other thing is that textures seem to be slightly blured.

Any help on these two issues would be greatly appreciated

Put anti-aliasing into the search button. Only prob is that in the current release you cannot use anti-aliasing and sprites. Think they might have fixed it in the 7.5 Beta.

It sounds like you have the resolution set too low. Make sure you set the resolution to the values returned by 'desktop width()' and 'desktop height()' for best results.

I use the Anisotropic filtering dll by @kaedroho for this it works really well and has little to no impact on FPS!

I think he's talking about aliasing.

If it hasn't exploded yet, I haven't touched it.

in that case, I think the set display mode command has an optional flag to turn it on, but when aa is turned on you can't use sprites or get/paste image...

You can't use GET IMAGE, that's true. Sprites prior to the latest 7.5 release would disable anti-aliasing, but I fixed that for this release.

Darn, then I won't be using it in EnviroSCOPE after all...

I was hoping to improve the edge drawing but I need "get image" to make the skybox textures as using "point" is too slow.

Does the STYX plugin work with get image I assume not?

STYX dissapointinly doesn't work with the sprites. I wouldn't say it works with get image either :S

Edit: Are you running in full screen exclusive mode? This smooths the screen and gives better performace than the regular full screen mode.

you can try using memblocks instead of 'get image' to make the textures..

I'm no good with memblocks, how do I get from screen to memblock without using "get image"? Are you suggesting I use "point" as this has been too slow by far compared to "get image"?

I doubt that memblocks will work. You may be able to use 'copy bitmap' however, to copy the data to an off-screen bitmap, and then use 'get image' on that/

i think memblocks are faster.. and you can set an alpha channel

With memblocks you can

1. Copy the backbuffer to a memblock and convert it to an image
2. Create the image directly on the memblock

but that would be hard to do if you dont know about mems. I tested what diggsey said, that works too and seems a lot easier :

Yes but memblocks don't work with a multisampled backbuffer, which was the problem to solve

Try it yourself:

i think the crash is because bitmap 0 is not really a 'bitmap'

im trying to make my own 'get image', help!
whats wrong here? i think those pointers are wrong, i dont know how to use them correctly

No the crash is because you can't convert a multisample bitmap into a memblock. Try disabling multisampling and the code will work fine.

Bitmap 0 is as much a bitmap as any other

Hey guys,

thanks for all the responses! Sorry for the slow reply - was away this week but will test these solutions out over the weekend. I will upload a photo of the edge issue I was talking about later today.

Thanks for helping me out!
