using vizzie and jit.gl.pix to post process a 3d scene

 https://youtu.be/LiUCD-8vgFY a few last bits from this vid



just a quick post.. Using the last post's setup, I wanted to do some 2d post processing. As if i was sending my renders to Nuke/After Effects..do a bit of blur, hue-sat, that sort of thing.

The gist is - use jit.gl.node with @capture set to 1. Then attach everything you want to put on this layer into the middle output (i don't know why they don't have this on the top). The connected objects will then disappear from your jit.world window. Next you need to plug the left output of the gl.node into a jit.gl.layer. The selected objects should show up again. Now the interesting stuff, you can use vizzie nodes like BRCOSA, SLIDR etc inbetween the gl.node and gl.layer. Or say you want to composite them a bit? We use something called jit.gl.pix. You plug something into the left and something into the right, a bit like a Merge node in Nuke. If you lock the patch (or hold control) and double click the .gl.pix node, you can enter it and see what's inside.


Next - the contents of the gl.pix

so we can do stuff here - the default is just a + which adds the inputs. But Ive changed it here to a mix. Will cover more advanced jit.gl.pix and layering stuff in future posts. But this all looks quite cool!

load texture using path

  This is supposed to be a fast and automated way of loading textures into the jit.gl.texture... Honestly... it would be far quicker to drag the images onto the object as mentioned in the previous post, but I guess it is worth mentioning the "this patcher" object which provides the path for where the patch has been saved (displayed using the message object). It seems like you have to pass it a "path" message for it to output the info. Next we use sprintf to add the rock/Rock..............etc to the end of the path. I believe the %s represents the string that you pass into the sprintf object, eg the path. The symout is present to process any symbols or spaces as text. Prepend adds the "read" message in front of the full path of the texture file, this gets piped into the jit.gl.texture and when banged the texture should be loaded in. You might find you have to click some of the upper bits of the path to trigger it all. I find this method a bit extra, but I d...

jit.gl.camera basics

Image
jit.gl.camera is the camera object. It starts off at position 0, 0, 2. That's 2 units "out towards the screen". Z positive is out of the screen towards you. You can set the position using the @position attribute with floats. Or, you can drive the camera using WASD, QZ and the mouse. The default speed is a bit crazy, so you should probably lower it to about 10.  @ui_listen lets you actively drive, @ease lets you tweak the easing of the motion. There are a few other parameters to tweak but these are the main ones. @tripod stops the camera from twisting on the Z axis.
