 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 en...

 Notes from Ned Rush's 80's retro visuals video - https://youtu.be/LiUCD-8vgFY What' we're making - spheres instanced onto a noisy point base AND making a weird grid thing that connects all the points up  Going to break down several parts of this video separately so it's easier to search for on this blog.  Firstly introducing noise to the points that we're instancing onto.     firstly we make a gridshape to define the shape - here we're using a torus and we make sure we are outputting the matrix. Lets setup the shapes we're instancing next. We're using spheres. We're going to use a jit.noise with 3 planes (3 axes) of type float32 (values 0-1) and size of 2 2 2 (fairly low frequency noise, think of 3d textures). I remap the noise using jit.map to a range of -4 to 4.   Now... we can actually plug the result of the noise or map straight into the jit.* to multiply the torus matrix, and that will work, but the noise will need to be banged. I'm usi...

 Might be a long post...it's a bunch of notes about this  video by Federico. He's using Max 8.something, I'm hoping this knowledge is not obsolete with the new 3d jitter geom stuff that we got in Max 9! ANYWAY. To instance jit.gl shapes we use something called jit.gl.multiple (I think this used to be called jit.gl.multipleS) and plug it into the jit.gl.mesh we want to instance all over the place. It takes a few specific attributes, which will create extra inputs on the top of the node when we specify we are using them. Notice we specify the "context" or the name of the gl.world (myWorld) and the number of inputs we want (3). We also have to use the @glparam to specify the parameters...for whatever reason.    First lets tackle what we want to plug into the position . All of these inputs will need to be matrices. We could use a noise with 3 values as a position vector. We'd use the "jit.noise" node. This creates values between 0 and 1. We'll need t...
