Q1 What does the name mean?
Q2 Why does the wireframe flicker and look all jaggy?
If the GPU does not support the
GL_EXT_geometry_shader4 OpenGL extension, Dilay (version 1.6.1 or higher) uses a fallback method for wireframe rendering which doesn’t look very pretty, but is probably better than nothing.
Q3 What to do if Dilay crashes when enabling wireframe rendering?
Start Dilay version 1.6.1 or higher, go to Edit -> Configuration -> Misc, and disable Use geometry shader. Then restart Dilay. Now wireframe rendering should work, albeit looking a bit off (see previous question).
Q4 Can you point out resources you found useful for developing Dilay?
While developing Dilay, different approaches for its sculpting tools have been tested and evaluated. The following list cites papers where some of the underlying techniques are described:
Sculpting and smoothing
