Draw a stroke and switch to edit mode in the top left corner of the 3D viewport. Start Blender and choose the "2D Animation" template. Run git checkout soc-2020-greasepencil-curve before building to switch to the branch. Link to the final patch: How does curve edit mode work? Getting StartedĬurrently, to use the features explained below, you need to build the soc-2020-greasepencil-curve branch yourself.
In the end, all of the changes were compiled into a single patch and submitted to for review. These changes in the plan don't affect the way the end-user interacts with the feature by much but made it a lot easier to implement.Īll of the work was done on the soc-2020-greasepencil-curve branch on the main blender git repository.
Implementing it as a "mode" not only meant that no inputs would be blocked but also opened up the possibility to reuse existing operators from edit mode in curve editing mode. For obvious reasons, this was not the best approach. This would have meant that every interaction the user makes with the viewport would have to be handled by said tool. One of the most important reasons was that an interactive tool like the knife tool consumes all the inputs of the user while being active. As it turns out, there are numerous reasons not to implement curve editing as an interactive tool but rather as a "sub-mode" in edit mode. In the proposal, I suggested adding an "interactive edit mode tool". All of the main goals in my proposal were achieved. The main goal of the project was to provide a way to edit strokes using curve handles. As a 2D/3D animation-, drawing-, and illustration tool, grease pencil was missing an important feature requested by many in the community: Curves. This summer I got to work on grease pencil in Blender. Nevertheless, we suggest you test Pencil for yourself and find out if it fits your preferences.Editing Grease Pencil Strokes Using Curves - Final Report Summary
On the other hand, we would have liked the possibility of applying drawing effects and filters. The graphic editing tool requires a moderate amount of system resources, includes a brief online help file with snapshots and didn't freeze, crash or pop up errors during our tests. frame size in pixels, timeline size in frames). window opacity, shadows, vector curve opacity and smoothing) and options regarding files (e.g. In addition, you can configure options when it comes to color, size and feather, enable size with pressure, as well as preserve alpha, use a timeline, and others.įurthermore, you can use the undo and redo functions, import images and sounds, create a new layer (bitmap, vector, sound, camera), import a palette and export a SWF movie, image sequence, and more.īut you can also configure general settings (e.g. So, you can use basic editing tools, such as sketch, coloring, draw, polyline, erase, clear, fill, color picker, select, zoom and modify curves. You can start a new drawing from scratch or open an image via the file browser or "drag and drop" method (in the BMP format only). The interface of Pencil is plain and simple.
Plus, your Windows registry entries will not be changed. It means that it can be stored on a removable drive and used on any computer.
This is a portable software, so you don't have to install Pencil. Pencil is a simple application that provides you with some basic graphic editing tools.
