Create Dynamic OpenGL Scene Processing Chains

it crashes Max instantly when i bang to commit the change with this chain : bloom 1st, blur 2d, rota 3rd

Great article.

But Max also crashes if you turn off one of the effects so that less than a total of 3 cells are selected.

Looks like matrixctrl could use another attribute (in addition to @one/row and @one/column) that prevents you from turning off all the cells in a row or column (that is, if a cell is on, you wouldn't be able to click it off by clicking on it).

There seem to be various problems switching the order of the passes on the fly - I've been getting various crashes and freezes, as well as this error:

jit.gl.node: capture cannot be changed when bound to jit.gl.pass.

However, if I make sure to:

A) set enable 0 on all jit.gl.passes B) remove all child references on all passes C) reorder layers & specify parent/child relationships D) set enable 1 on all jit.gl.passes

everything seems to be OK (so far).

Ditto on crashes. Stage 2 and then Commit (Stage 3) crashes max. I think this was noted elsewhere in another thread.

I am not sure why using gl.pass over gl.pix or gl.slab It's possible to chain effects with either of these gl objects

I'm reading documentation and the logic of using one or another isn't clear to me.

Someone has a synthesis explanation?

good question. the best information on the technical aspects of jit.gl.pass is the Discussion section of the object's reference page. https://docs.cycling74.com/max7/maxobject/jit.gl.pass

there's nothing that can't be done using one or more gl.slab/pix objects. it is simply another format for creating multipass texture effects, and may or may not be more convenient for you.

for example, below is a side by side comparison of the bloom effect, jit.gl.pass vs no jit.gl.pass. and this is one of the most basic of the built-in pass effects.

i think the real power of this object comes with how easy it is to access multiple render target outputs (as described in the reference file linked above).

Hey thanks Rob

Sorry for late answer! Car accidents can put your life upside down!

Great comparison patch! Very useful! From what I understand Gl.pass is a way to "condense" code I mean assemble all the steps of multiple shaders "receipe" together.

Would you have a patch showing many different render targets?

Like in this jxp code I understand that the cf.edgedetect.jxs targets the COLOR of the image and multiply.jxs only of the COLOR of the PREVIOUS image? I guess another .jxs could be applied on the TEXTURE like lumadisplace ?

Next question Is there a step-by-step tutorial on how to create a .jxp?

The crash seems related to NVidia drivers: http://pastebin.com/ugJY2hLJ

hey guys, i'll be investigating a fix for this crash for the next update. thanks for the reports.
