any hint on anti-alias ?

[guillaume]

hi,  my app will run on a custom hardware, and it only support opengl es 1.0,
so how should  I implement anti-alias on my app with jPCT-AE ? thanks.

[EgonOlsen]

You can't. It isn't supported on ES 1.0 as far as i know.

[guillaume]

You can't. It isn't supported on ES 1.0 as far as i know.

thanks. so what's the minimum ES version should I get ?
or is there any other way to implement it ?

[EgonOlsen]

You need 2.0 for this. jPCT has a helper class in the util-package to enable it for an OpenGL ES 2.0 context.

by the way, I also tested my app with jPCT desktop version.
does code

Code Select Expand


buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_HARDWARE_ONLY);


will enable anti-alias ? the result seems no effect.
look the attach image

No, it doesn't. Either use FrameBuffer.SAMPLINGMODE_GL_AA_2X or FrameBuffer.SAMPLINGMODE_GL_AA_4X instead. Or force it in the driver settings.

[guillaume]

I try this.

Code Select Expand


buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_GL_AA_4X);


and the result  seems the same.  am I missing something others ?

see the attachment.

No, that's all there is to do. That doesn't mean that AA is supported on your platform. Many Intel onboard chips don't support it, for example.

[guillaume]

yes.  I am using intel onboard chips.
is there a software way to do anti-alias ?

[EgonOlsen]

No, not really. If it's not a laptop, go out and buy a cheap dedicated graphics card. Anything will do better than this Intel onboard crap (albeit they ARE improving, but it's about time...).
