What is the path frame?

Happy New Years guys! I'm working to increase my understanding of SA this year by studying the SA manual as in depth as I can. Right now I'm on chapter 9: bezier paths. I think I'm missing clarity for a few definitions and am hoping you can help me out. What exactly is a path frame? I couldn't find a definition of what it is. I think its the current bezier paths on the canvas for a particular frame but want to double check.

  • There is a bezier path frame associated with each layer. So each layer has a rgba raster image buffer ( red - green - blue - alpha), and a bezier path frame. You can think of the bezier path frame as the buffer where the bezier paths stored in the layer are recorded. If you are in bezier operation mode then you can see the contents of the bezier path frame displayed on the canvas. Otherwise they are hidden from view.

    When you switch to the different layer, it has it's own associated bezier path frame and the display would change accordingly when in bezier operation mode.

    Resizing the canvas scales all of the bezier path frames in addition to the raster image buffer. So a path that stretches across the canvas will continue to do so at the new canvas resolution.

    There are 4 global bezier path memories. You can use these as working buffers for saving and retrieving sets of bezier curves. So you could save a set of curves in a global memory, then switch to the new layer, and then play them back in to a new layer.

    There's also an internal bezier path memory in the paint synthesizer. You can use this internal path memory to encapsulate a set of bezier paths in a paint preset.

On the closure of the User Forum : An open letter to John Dalton

Hi John I have no idea what you are going through. However the impact you have made not to continue with the user forum and your desire keep it as a permanent feature as promised in the past is a big shock. It also betrays the faith and love we have shown in you and Studio Artist.  Bluntly spoken, it sucks. That you have chosen to follow this direction in silence, allowing no compassion or understanding on our part is a betrayal of the deepest level. What is going on? This is not the John…

Interdimensional Coincidence Control

Hi everyone, I am glad the site is still here! Here is a new short video I made. All made in Studio Artist, several separate videos with alpha channels, then combined in layers with the music in Blender. A lot of MSG running through brushes, with several of the brush Path Starts being controlled by the MSG Scan Generator in the Generator part of the Path Start in the Paint Synthesizer. Also some MSG running through a brush, then making a video of that with an alpha channel, then making that a…

Whats going on with this site?

Has anyone else gotten a warning about this site disappearing? An email form just popped up, asking me to contract the owner and leave a message to let them know that they may loose their "network"Did Synthetik forget to pay it's bills, or is something else going on?I think 8 months is more than enough vacation time. Is anyone at Synthetik doing any development work at all?
