New Meta Primitives: cone, pyramid, curve, donut, etc

Meta shapes have had a renaissance due to ray casting techniques. Most notably, Inigo Quilez’s Shadertoy work using simple signed distance functions on GPUs.

Blender (and every other 3D package) has had pretty basic “metaballs” features. But times are changing. I’d like to start a conversation about Blender’s meta system. Who else is interested in starting a development branch where we improve meta shapes?

Someone told me there are Blender builds with more metaball object types. Does anyone know where I can find those builds? I’m on a journey to rediscover the power of metaballs. :slightly_smiling_face:
