Everything is a simple form
- Rendering 塑造 means building smooth, believable volume from flat shapes.
- Every complex subject simplifies into basic forms 基本形体: sphere, cylinder, cube, cone.
- Render the simple form first; the likeness rides on top.
Which basic form hides inside?

Sphere, cylinder, cube, cone.
Work in one direction
- Work dark-to-light or light-to-dark consistently; jumping around destroys the value structure.
- A blending stump 擦笔 smooths values — but preserved marks often read stronger than over-blending.
- Keep the lit side and shadow side clearly separated: form collapses when halftones creep into shadow.

Each move has one job.
The white-object test
- Drawing white objects (eggs, cups, cloth) is the classic rendering test.
- With no local colour to hide behind, every value must come from light alone.
- One polished white-object study is strong evidence of the light and shade skill.

Over-blending kills solidity.
Over-blending is the beginner's comfort blanket: everything smooth, nothing solid. Blend the big transitions, but let marks survive — a rendered drawing is not a photograph of fog.
Render a cylinder: flat tone first, then darken the core shadow band, lift the light side, add reflected light near the far edge, and keep the top ellipse a clean halftone. Five moves — the tube turns.
Rendering = volume from value: simplify to basic forms, work in one direction, separate light from shadow, blend with restraint, and prove it all with a white-object study.
Write from a mug as a cylinder
- A mug is drawn by starting with a cylinder.
- The handle is added after the form is placed.
A student draws a mug by first constructing a cylinder and only then adding the handle. Why start with the simple form?
The large form is placed before the small part.
What should be drawn first?

The mug's volume is a cylinder. The handle hangs on that form.
