Hijack viewport for preview rendering 2009年11月22日17:41

I have heard of people who are hijacking the houdini viewport and render directly to it. The idea is to enable quick previews. I.e. if we are simulating millions of particles in a custom made SOP using the GPU it would be great to render directly to the viewport and not have to copy them back to houdini first.

Another approach would be to render the particles to a buffer and then convert the buffer into an image and make houdini display it. Would that be possible?

Or, simply open our own opengl-preview window from the SOP and render to that…

Any ideas?
Thanks.

Off course! Period of one… now I feel like an idiot

Thanks for pointing that out. And also, thanks for the quick response!

Hi,

I know how a noise-function works. The whole idea is to get the same “random” number every time at a certain position.

The problem is

hou.hmath.noise1d(hou.Vector3(1.0,1.0,5.0))
hou.hmath.noise1d(hou.Vector3(2.0,1.0,2.0))
hou.hmath.noise1d(hou.Vector3(4.0,1.0,1.0))

all return 0.5

is this function not implemented yet?
