operations with texture vs matrix
Hi, very basic question (sorry):
Why do I get some grey lines separating the pixels when I am using jit.gl.texture (texture generated from jit.matrix) vs when I always stay in the jit.matrix world?
Please see the patch below. I understand this is an extremely basic question for more advanced jitter users. I am sorry, and thank you for all the help you can provide to understand this.
So... I've found that if I change the resolution of the original matrix I can "fix" this issue.
I understand the problem I am facing relates somehow with what is intrinsically different between matrices and textures: one uses pixels and the other vectors. This is just my intuition talking.
I would love if someone could share some more well articulated insights into this.
Also, why does the jit.gl.texture output seems fine whereas if I connect the small matrix directly to a jit.gl.pix it will unavoidably show the "pixel interpolation" effect? I am just trying to learn this part of Max a bit better.
Here is another walkaround based on the suggestion by mattyo here:
I still don't understand some things though: on the red jit.gl.pix object, why do I get 2 shades of dark further down the line when I insert a vec 0 in between in1 and out1? Because these are single channel black and white matrices, I would guess the equivalent would be a vec with a single index.
