<div dir="ltr"><div><div><div><div><div>Hi all,<br><br>I have a 1900 x 800 gemwin. I render a few geos on a big [sphere] and a pmpd system on top of it.<br></div><br></div>I'd need some cpu-friendly motion blur and glow effects on everything rendered in the gemwin.<br>
<br></div>My strategy so far has been to split the final rendering into two 800x800 squares. That is:<br><br>I have two [snap2tex] snapping two separate [gemwin -1] onto two [square]. One [snap2tex] has 0 0 offset, and the other has 800 0 offset. Then, by modulating the opacity of [colorRGB] for the 2 squares I can get motion blur effect.<br>
<br></div>This works fine, but the same splitting strategy doesn't work for shaders. If I apply a shader to the two [square] the coordinate of the texture are all mixed up.<br><br></div><div>Also, when applying the shaders the cpu go up +30%, whereas [snap2 tex] takes way less resources. is that normal?<br>
</div><div><br></div>What's the best way to go here?<br><div><div><div><div><div><div><div><br></div><div>thanks!<br>best,<br></div><div><br clear="all"><div><div dir="ltr">--<br>Marco Donnarumma<br>New Media + Sonic Arts Practitioner, Performer, Teacher, Director.<br>
