Based on my potentially wrong understanding of jit.gl.sketch or opengl, can I do in other gl objects what can be done in gl.sketch? Specifically want to be able to draw shapes by specifying the vertices such as with glvertex. The reason I ask is that I've been told the sketch object is _older_ and more recent objects should be strongly considered instead. Does jit.gen replace sketch? I don't know.

I am also interested in this. I plan on digging into some gl stuff, and would rather not pursue particular solutions, if better ones are available.

Wish I had some answers, but all I have is questions when it comes to opengl.

Based on my research here is a long quote from a Max dev who posted this a year or so ago in a FB forum:

“jit.gl.sketch is great object, but is one of the earliest gl objects and is slightly deprecated. back in the max 4/5 days it was the only way to do certain things (lighting, shading, grouping, camera moves, capture to texture, etc), but as of max 6, that is no longer the case.

i highly recommend beginners start with the higher level gl objects (gl.gridshape, gl.mesh, gl.camera, gl.light, gl.material, gl.slab, gl.texture). after gaining an understanding of these objects, start incorporating a gl.node and gl.pass effects for scene processing.

the next step would be to start customizing your texture effects using gl.slab and gl.pix. gl.slab loads JXS files, which are simply jitter-wrappers around raw glsl shader code. gl.pix allows you to use the gen environment to generate glsl code. whichever makes you happier, but gl.pix is the future.

if vertex/geometry manipulations are of interest jit.gen and gl.mesh or gl.isosurf are the path to happiness. using jit.gen for vertex manipulations (as opposed to a vertex shader) allows you to plug the matrix directly into a jit.phys.body, if using physics.

gl.model allows you to import animated models from 3d modeling environments, and gl.multiple allows you to quickly create multiple instances of objects and manipulate them with jitter matrices. text rendering is handled with gl.text, and animations via the jit.anim.* objects and the jit.phys.* objects. everything can be accessed via JS, for when your patch gets too complex.”

Also I may have found an unexplained patch that demonstrates an example how to draw things without sketch, I think. The patch is called, "jit.gen.superformula.maxpat"

Can I do things in other objects that can be done in [jit.gl.sketch]?
