i'v got a problem with some drawing in opengl..

first i generate the plane in @poly_mode 1 1 with @dim 20 2, to get the stripes, then i store the texture in jit.gl.node, and with jit.gl.slab i am substracting it with an alpha mask and next to jit.gl.videoplane. untill now everythink goes right, but when i*am trying to turn on the lighting on videoplane, the resolution is geting low. the only solution that i found, is to increase the @dim on the videoplane, but then i loose the performance.. anyway i have posted here my patch, with the sample video, and skeleton data from kinect. the other problem is when i turn on the fullscreen, everything is getting buggy, and the axes of light is moving with +- 0.5 fps. i would be thankful for any help!

Could you post something other than a RAR? A ZIP file would be better and a compressed patcher even better.

i'am compressing it, because the mov file, is 100 mb.

wow it is you again :) big thanks!

For whatever reason, the zip file doesn't work for me.

You shouldn't need to increase the dim on the videoplane to create a spotlight effect. If you need 3D lighting, have a look at jit.gl.light (Max6). If you just want an image of a spotlight to modulate the texture, you could use jit.gl.slab and a custom shader in Max5 or jit.gl.pix in Max6. Using jit.gl.pix it should be pretty simple to make a nice looking spotlight.

yes yes! i would like only to modulate the texture. i'am using max 6 and using jit.gl.light, but the jit.gl.pix is some sort of magic for me.. could you help me with this?

napentro, i think these are simply the artifacts that appear when you draw lines with opengl.

you could get better results by setting @antialias 1 on your gridshape, and @fsaa1 on your window. you might want to add some gaussian blur to your output texture as well.

the fullscreen slowdown happens because you are reading your back to a matrix to view with the pwindow.

get rid of that, and you should be fine in fullscreen.

a better solution for a pwindow preview is to use a shared_context.

i dont know if you get me right, because my problem begins when you open the "jit.gl_stuff" patcher, and turn on the lighting. only then the fulscreen is getting buggy and the problems with resolution is starting. sorry for my google translator english, but i think, you get me

i have made another atempt, and stopped on quite similar thing. with this less complicated patch i am trying to get silhouette, with lights on hands and foots. i have got problem, to improve the quality of lights with no lose of performance. next i want to add those stripes some how.. maybe the jit.gl.material will be usefull?

Thanks in advance!


but now i got porblems with fullscreen performance..

i did it with gl.slab and it works :))
 but now i got porblems with fullscreen performance..


i v got another, more simplyfied version with the same problem...

i found that now the problem is in the gaussian blur, that is eating my fps :)

it should be done with gpu and i am messed up..

do you know why is it happened?

i simplified the question and patch and i started new topic.

do you know is there any way to delate topic?
