How can I create large-scale pixelart using [jit.scissors], please?
Dec 17 2015 | 12:53 am
Hi there,
I'm fairly new to Max/jitter and have looked for a simple solution but have not been able to find one, so far :( I am creating live visuals for a project and would love to be able to include pixel-art as part of the performance and am looking for help/advice on how this can be done, please?
I am running Max 7 on El Cap! and using [jit.scissors] to split a video into 12 rows by 16 columns, as used by most 8-bit pixel art. I would like to be able to control the colour of each [jit.scissors] video outlet to create an 8-bit pixel-image. I would also, if possible, like to have the ability to produce different pixel-art as well; e.g. have a pixel-art of Super Mario that can be changed to him jumping, and vice-versa.
Many thanks :)
- Dec 17 2015 | 2:56 amAnother approach is to use [matrixctrl] to set pixel values in a single matrix and [suckah] to select 8-bit colors from a palette image. For the animation, you can draw each frame and save the [matrixctrl] values to recall in sequence or use other jitter tricks to shift cells etc. Here is something to get you going in that direction.

- Dec 21 2015 | 5:51 amHi Jamie ,you could cheat and simply downsample your image@YGREQ : I posted a jit.gl.scissor last summer. Look it up, it's quite flexible. using jit.gl.shader and multiple etc... can get crazy results with high fps
- Dec 21 2015 | 11:41 pmThanks for all the info and advice, very much appreciated :)@ Metamax: The patch you sent was ideal for my purpose (i.e. overlaying blocks of colour onto a video that would produce a pixel-art effect) however, I can't see how the patch is made and don't know enough about Max/Jitter (yet) and the objects to work it out. There is a problem with the patch in that when I use the [preset] object it causes the [mtrxctrl] to display a single colour throughout the matrix on recall. I imagine that this may be because the preset needs to be attached to specific objects to prevent this?@ Ygreq; Just after I posted this I realised that using [jit.scissors] would be too much as having 192 matrices (12x16 outlets), with each having a separate patch to control colour schemes, would suck the life out the CPU.@ Phiol: This patch is more pixellation of the image than creating pixel-art (think 8-bit console game images, like Mario). However, i like what this patch does and it taught me something new and it will definitely come in very handy, so thank you :)
- Dec 22 2015 | 3:33 amJamie, not sure what's up with [preset], but in this case, each matrix frame can be saved as a .jxf file. Save the patch somewhere and the frames will be saved to the same folder. There's an easier way to do this with [jit.matrixset] but this should work okay. Good luck. I also attached an example .jxf file because, well.. I couldn't resist. hehe
- Dec 22 2015 | 3:35 amWhoops.. never mind. Apparently I can't attach .jxf files.
- Dec 22 2015 | 5:07 amsomething like this ?
- Dec 22 2015 | 5:13 amI think more like this... :P
- Dec 22 2015 | 5:14 amright on metamax :-)
